详解spring security四种实现方式

浏览：19日期：2023-08-03 15:17:48

spring security实现方式大致可以分为这几种：

1.配置文件实现，只需要在配置文件中指定拦截的url所需要权限、配置userDetailsService指定用户名、密码、对应权限，就可以实现。

2.实现UserDetailsService，loadUserByUsername(String userName)方法，根据userName来实现自己的业务逻辑返回UserDetails的实现类，需要自定义User类实现UserDetails，比较重要的方法是getAuthorities()，用来返回该用户所拥有的权限。

3.通过自定义filter重写spring security拦截器，实现动态过滤用户权限。

4.通过自定义filter重写spring security拦截器，实现自定义参数来检验用户，并且过滤权限。

1.最简单配置spring-security.xml，实现1

2.实现UserDetailsService

先整理下spring secruity验证流程：

springSecurity的登录验证是由org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter这个过滤器来完成的,在该类的父类AbstractAuthenticationProcessingFilter中有一个AuthenticationManager接口属性,验证工作主要是通过这个AuthenticationManager接口的实例来完成的。在默认情况下，springSecurity框架会把org.springframework.security.authentication.ProviderManager类的实例注入到该属性

UsernamePasswordAuthenticationFilter的验证过程如下：

1. 首先过滤器会调用自身的attemptAuthentication方法，从request中取出authentication, authentication是在org.springframework.security.web.context.SecurityContextPersistenceFilter过滤器中通过捕获用户提交的登录表单中的内容生成的一个org.springframework.security.core.Authentication接口实例.

2. 拿到authentication对象后，过滤器会调用ProviderManager类的authenticate方法，并传入该对象

3.ProviderManager类的authenticate方法中会调用类中的List<AuthenticationProvider> providers集合中的各个AuthenticationProvider接口实现类中的authenticate(Authentication authentication)方法进行验证，由此可见，真正的验证逻辑是由各个AuthenticationProvider接口实现类来完成的。DaoAuthenticationProvider类是默认情况下注入的一个AuthenticationProvider接口实现类

4.provider的实现类在验证用户时，会调用userDetailsService的实现类的loadUserByUsername方法来获取用户信息，

首先spring-security配置文件

<?xml version='1.0' encoding='UTF-8'?><beans:beans xmlns='http://www.springframework.org/schema/security' xmlns:beans='http://www.springframework.org/schema/beans' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd'>  <http auto-config='true' use-expressions='false'>   <intercept-url pattern='/login.jsp*' access='IS_AUTHENTICATED_ANONYMOUSLY'/>  <intercept-url pattern='/**' access='ROLE_USER'/>  <form-login login-page='/login.jsp' default-target-url='/jsp/index/main.jsp' authentication-failure-url='/login.jsp?error=true'/>   </http> <authentication-manager alias='authenticationManager'>  <authentication-provider user-service-ref='msecurityManager'>  <password-encoder ref='myPasswordEncoder'/> </authentication-provider> </authentication-manager>  <beans:bean class='com.ultrapower.me.util.security.support.SecurityManagerSupport'></beans:bean>  <beans:bean /> </beans:beans>

userDetailsService实现：

/** * */package com.ultrapower.me.util.security.support;import java.util.ArrayList;import java.util.HashMap;import java.util.HashSet;import java.util.List;import java.util.Map;import java.util.Set;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.dao.DataAccessException;import org.springframework.jdbc.core.JdbcTemplate;import org.springframework.security.core.userdetails.UserDetails;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.core.userdetails.UsernameNotFoundException;import com.ultrapower.me.util.Constants;import com.ultrapower.me.util.dbDao.SpringBeanUtil;import com.ultrapower.me.util.security.SecurityManager;import com.ultrapower.me.util.security.entity.Resource;import com.ultrapower.me.util.security.entity.Role;import com.ultrapower.me.util.security.entity.User;import com.ultrapower.me.util.task.PasswordUtils;public class SecurityManagerSupport implements UserDetailsService{ private Log log = LogFactory.getLog(this.getClass().getName()); public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException, DataAccessException {// List<User> users = getHibernateTemplate().find('FROM User user WHERE user.name = ? AND user.disabled = false', userName); log.info('SecurityManagerSupport.loadUserByUsername.userName:'+userName); User user =null; if('admin'.equals(userName)){ Set<Role> roles = new HashSet<Role>() ; Role role = new Role(); role.setRoleid('ROLE_USER'); role.setRoleName('ROLE_USER'); Set<Resource> resources=new HashSet<Resource>() ; Resource res = new Resource(); res.setResid('ME001'); res.setResName('首页'); res.setResUrl('/jsp/index/main.jsp'); res.setType('ROLE_USER'); res.setRoles(roles); resources.add(res); role.setResources(resources); roles.add(role); user = new User(); user.setAccount('admin'); user.setDisabled(false); user.setPassword(PasswordUtils.entryptPassword(Constants.securityKey)); log.info(user.getPassword()); user.setRoles(roles); } return user;//返回UserDetails的实现user不为空，则验证通过 } }

UserDetails实现：

/** * */package com.ultrapower.me.util.security.entity;import java.util.ArrayList;import java.util.Collection;import java.util.HashMap;import java.util.List;import java.util.Map;import java.util.Set;import org.apache.commons.lang.StringUtils;import org.springframework.security.core.GrantedAuthority;import org.springframework.security.core.authority.SimpleGrantedAuthority;import org.springframework.security.core.userdetails.UserDetails; public class User implements UserDetails { private static final long serialVersionUID = 8026813053768023527L; private String account; private String name; private String password; private boolean disabled; private Set<Role> roles; private Map<String, List<Resource>> roleResources; /** * The default constructor */ public User() { } /** * Returns the authorites string * * eg. * downpour --- ROLE_ADMIN,ROLE_USER * robbin --- ROLE_ADMIN * * @return */ public String getAuthoritiesString() { List<String> authorities = new ArrayList<String>(); for(GrantedAuthority authority : this.getAuthorities()) { authorities.add(authority.getAuthority()); } return StringUtils.join(authorities, ','); } @Override public Collection<? extends GrantedAuthority> getAuthorities() { // 根据自定义逻辑来返回用户权限，如果用户权限返回空或者和拦截路径对应权限不同，验证不通过 if(!roles.isEmpty()){ List<GrantedAuthority> list = new ArrayList<GrantedAuthority>(); GrantedAuthority au = new SimpleGrantedAuthority('ROLE_USER'); list.add(au); return list; } return null; } /* * 密码 */ public String getPassword() { return password; } /* * 用户名 */ public String getUsername() { return name; } /* *帐号是否不过期，false则验证不通过 */ public boolean isAccountNonExpired() { return true; } /* * 帐号是否不锁定，false则验证不通过 */ public boolean isAccountNonLocked() { return true; } /* * 凭证是否不过期，false则验证不通过 */ public boolean isCredentialsNonExpired() { return true; } /* * 该帐号是否启用，false则验证不通过 */ public boolean isEnabled() { return !disabled; } /** * @return the name */ public String getName() { return name; } /** * @return the disabled */ public boolean isDisabled() { return disabled; } /** * @return the roles */ public Set<Role> getRoles() { return roles; } /** * @return the roleResources */ public Map<String, List<Resource>> getRoleResources() { // init roleResources for the first time System.out.println('---------------------------------------------------'); if(this.roleResources == null) { this.roleResources = new HashMap<String, List<Resource>>(); for(Role role : this.roles) { String roleName = role.getRoleName(); Set<Resource> resources = role.getResources(); for(Resource resource : resources) { String key = roleName + '_' + resource.getType(); if(!this.roleResources.containsKey(key)) { this.roleResources.put(key, new ArrayList<Resource>()); } this.roleResources.get(key).add(resource); } } } return this.roleResources; } /** * @param name the name to set */ public void setName(String name) { this.name = name; } /** * @param password the password to set */ public void setPassword(String password) { this.password = password; } /** * @param disabled the disabled to set */ public void setDisabled(boolean disabled) { this.disabled = disabled; } /** * @param roles the roles to set */ public void setRoles(Set<Role> roles) { this.roles = roles; } public String getAccount() { return account; } public void setAccount(String account) { this.account = account; } public void setRoleResources(Map<String, List<Resource>> roleResources) { this.roleResources = roleResources; } }

3.实现动态过滤用户权限

在spring-security配置文件的http标签中添加如下配置

<custom-filter before='FILTER_SECURITY_INTERCEPTOR' ref='securityInterceptor'/>

在spring-security配置文件中添加如下配置

<beans:bean class='com.ultrapower.me.util.security.interceptor.SecurityInterceptor'> <beans:property name='authenticationManager' ref='authenticationManager'/> <beans:property name='accessDecisionManager' ref='mesecurityAccessDecisionManager'/> <beans:property name='securityMetadataSource' ref='secureResourceFilterInvocationDefinitionSource' /> </beans:bean> <beans:bean /> <beans:bean />

securityInterceptor继承AbstractSecurityInterceptor过滤器，实现Filter过滤器

package com.ultrapower.me.util.security.interceptor;import java.io.IOException;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import org.springframework.security.access.SecurityMetadataSource;import org.springframework.security.access.intercept.AbstractSecurityInterceptor;import org.springframework.security.access.intercept.InterceptorStatusToken;import org.springframework.security.web.FilterInvocation;import org.springframework.security.web.access.intercept.FilterInvocationSecurityMetadataSource;public class SecurityInterceptor extends AbstractSecurityInterceptor implements Filter{ //配置文件注入 private FilterInvocationSecurityMetadataSource securityMetadataSource; public FilterInvocationSecurityMetadataSource getSecurityMetadataSource() { return securityMetadataSource; } public void setSecurityMetadataSource( FilterInvocationSecurityMetadataSource securityMetadataSource) { this.securityMetadataSource = securityMetadataSource; } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // TODO Auto-generated method stub FilterInvocation fi = new FilterInvocation(request, response, chain); //fi里面有一个被拦截的url //里面调用MyInvocationSecurityMetadataSource的getAttributes(Object object)这个方法获取fi对应的所有权限 //再调用MyAccessDecisionManager的decide方法来校验用户的权限是否足够 InterceptorStatusToken token = super.beforeInvocation(fi); try { //执行下一个拦截器 fi.getChain().doFilter(fi.getRequest(), fi.getResponse()); } finally { super.afterInvocation(token, null); } } @Override public void init(FilterConfig arg0) throws ServletException { // TODO Auto-generated method stub } @Override public Class<?> getSecureObjectClass() { // TODO Auto-generated method stub return FilterInvocation.class; } @Override public SecurityMetadataSource obtainSecurityMetadataSource() { // TODO Auto-generated method stub return this.securityMetadataSource; } @Override public void destroy() { // TODO Auto-generated method stub }}

登陆后，每次访问资源都会被这个拦截器拦截，会执行doFilter这个方法，这个方法调用了invoke方法，其中fi断点显示是一个url（可能重写了toString方法吧，但是里面还有一些方法的），最重要的是beforeInvocation这个方法，它首先会调用MyInvocationSecurityMetadataSource类的getAttributes方法获取被拦截url所需的权限，在调用MyAccessDecisionManager类decide方法判断用户是否够权限。弄完这一切就会执行下一个拦截器。

secureResourceFilterInvocationDefinitionSource实现

/** * */package com.ultrapower.me.util.security.interceptor;import java.util.ArrayList;import java.util.Collection;import java.util.HashMap;import java.util.Iterator;import java.util.Map;import javax.servlet.ServletContext;import org.springframework.beans.factory.InitializingBean;import org.springframework.security.access.ConfigAttribute;import org.springframework.security.access.SecurityConfig;import org.springframework.security.web.FilterInvocation;import org.springframework.security.web.access.intercept.FilterInvocationSecurityMetadataSource;import org.springframework.util.AntPathMatcher;import org.springframework.util.PathMatcher;public class SecureResourceFilterInvocationDefinitionSource implements FilterInvocationSecurityMetadataSource, InitializingBean { private PathMatcher matcher; private static Map<String, Collection<ConfigAttribute>> map = new HashMap<String, Collection<ConfigAttribute>>(); /* * 初始化用户权限，为了简便操作没有从数据库获取 * 实际操作可以从数据库中获取所有资源路径url所对应的权限 */ public void afterPropertiesSet() throws Exception { this.matcher = new AntPathMatcher();//用来匹配访问资源路径 Collection<ConfigAttribute> atts = new ArrayList<ConfigAttribute>(); ConfigAttribute ca = new SecurityConfig('ROLE_USER'); atts.add(ca); map.put('/jsp/index/main.jsp', atts); Collection<ConfigAttribute> attsno =new ArrayList<ConfigAttribute>(); ConfigAttribute cano = new SecurityConfig('ROLE_NO'); attsno.add(cano); map.put('/http://blog.csdn.net/u012367513/article/details/other.jsp', attsno); } @Override public Collection<ConfigAttribute> getAttributes(Object object) throws IllegalArgumentException { // TODO Auto-generated method stub FilterInvocation filterInvocation = (FilterInvocation) object; String requestURI = filterInvocation.getRequestUrl(); //循环资源路径，当访问的Url和资源路径url匹配时，返回该Url所需要的权限 for(Iterator<Map.Entry<String, Collection<ConfigAttribute>>> iter = map.entrySet().iterator(); iter.hasNext();) { Map.Entry<String, Collection<ConfigAttribute>> entry = iter.next(); String url = entry.getKey(); if(matcher.match(url, requestURI)) {return map.get(requestURI); } } return null; } @Override public Collection<ConfigAttribute> getAllConfigAttributes() { // TODO Auto-generated method stub return null; } /* (non-Javadoc) * @see org.springframework.security.intercept.ObjectDefinitionSource#getConfigAttributeDefinitions() */ @SuppressWarnings('rawtypes') public Collection getConfigAttributeDefinitions() { return null; } /* (non-Javadoc) * @see org.springframework.security.intercept.ObjectDefinitionSource#supports(java.lang.Class) */ public boolean supports(@SuppressWarnings('rawtypes') Class clazz) { return true; } /** * * @param filterInvocation * @return */ @SuppressWarnings('unchecked') private Map<String, String> getUrlAuthorities(org.springframework.security.web.FilterInvocation filterInvocation) { ServletContext servletContext = filterInvocation.getHttpRequest().getSession().getServletContext(); return (Map<String, String>)servletContext.getAttribute('urlAuthorities'); }}

mesecurityAccessDecisionManager实现

package com.ultrapower.me.util.security.interceptor;import java.util.Collection;import java.util.Iterator;import org.springframework.security.access.AccessDecisionManager;import org.springframework.security.access.AccessDeniedException;import org.springframework.security.access.ConfigAttribute;import org.springframework.security.access.SecurityConfig;import org.springframework.security.authentication.InsufficientAuthenticationException;import org.springframework.security.core.Authentication;import org.springframework.security.core.GrantedAuthority;public class SecurityAccessDecisionManager implements AccessDecisionManager { /** * 检查用户是否够权限访问资源 * authentication 是从spring的全局缓存SecurityContextHolder中拿到的，里面是用户的权限信息 * object 是url * configAttributes 所需的权限 * @see org.springframework.security.access.AccessDecisionManager#decide(org.springframework.security.core.Authentication, java.lang.Object, java.util.Collection) */ @Override public void decide(Authentication authentication, Object object, Collection<ConfigAttribute> configAttributes) throws AccessDeniedException, InsufficientAuthenticationException { // 对应url没有权限时，直接跳出方法 if(configAttributes == null){ return;} Iterator<ConfigAttribute> ite=configAttributes.iterator(); //判断用户所拥有的权限，是否符合对应的Url权限，如果实现了UserDetailsService，则用户权限是loadUserByUsername返回用户所对应的权限 while(ite.hasNext()){ ConfigAttribute ca=ite.next(); String needRole=((SecurityConfig)ca).getAttribute(); for(GrantedAuthority ga : authentication.getAuthorities()){ System.out.println(':::::::::::::'+ga.getAuthority());if(needRole.equals(ga.getAuthority())){ return; } } } //注意：执行这里，后台是会抛异常的，但是界面会跳转到所配的access-denied-page页面 throw new AccessDeniedException('no right'); } @Override public boolean supports(ConfigAttribute attribute) { return true; } @Override public boolean supports(Class<?> clazz) { return true; }}

4.实现AuthenticationProvider，自定义参数验证

这种验证以前项目用过，现在没有写示例代码，先写下大概流程和需要用到的类

这种验证的好处：可以在自定义登录界面添加登录时需要的参数，如多个验证码等、可以修改默认登录名称和密码的参数名

整体流程：

1.用户登录时，先经过自定义的passcard_filter过滤器，该过滤器继承了AbstractAuthenticationProcessingFilter，并且绑定了登录失败和成功时需要的处理器(跳转页面使用)

2.执行attemptAuthentication方法，可以通过request获取登录页面传递的参数，实现自己的逻辑，并且把对应参数set到AbstractAuthenticationToken的实现类中

3.验证逻辑走完后，调用 this.getAuthenticationManager().authenticate(token);方法，执行AuthenticationProvider的实现类的supports方法

4.如果返回true则继续执行authenticate方法

5.在authenticate方法中，首先可以根据用户名获取到用户信息，再者可以拿自定义参数和用户信息做逻辑验证，如密码的验证

6.自定义验证通过以后，获取用户权限set到User中，用于springSecurity做权限验证

7.this.getAuthenticationManager().authenticate(token)方法执行完后，会返回Authentication，如果不为空，则说明验证通过

8.验证通过后，可实现自定义逻辑操作，如记录cookie信息

9.attemptAuthentication方法执行完成后，由springSecuriy来进行对应权限验证，成功于否会跳转到相对应处理器设置的界面。

1.自定义PassCardAuthenticationToken类，继承AbstractAuthenticationToken类，用于定义参数，需要实现的方法

/** * 凭证，用户密码 */ @Override public Object getCredentials() { return password; } /** * 当事人，登录名用户Id */ @Override public Object getPrincipal() { return userID; }

2.User类要实现Authentication，需要实现的方法

/** * 返回用户所属权限 */ @Override public Collection<GrantedAuthority> getAuthorities() { return this.accesses; } @Override public Object getCredentials() { return null; } @Override public Object getDetails() { return null; } /** * 登录名称 */ @Override public Object getPrincipal() { return loginName; } /** * 是否认证 */ @Override public boolean isAuthenticated() { return this.authenticated; } /** * 设置是否认证字段 */ @Override public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException { this.authenticated=isAuthenticated; }

3.需要userService实现AuthenticationProvider的 authenticate(Authentication authentication)方法

@SuppressWarnings('unchecked') @Override public Authentication authenticate(Authentication authentication) throws AuthenticationException { PassCardAuthenticationToken token=(PassCardAuthenticationToken)authentication; /* * 这里进行逻辑认证操作，可以获取token中的属性来自定义验证逻辑，代码验证逻辑可以不用管 * 如果使用UserDetailsService的实现类来验证，就只能获取userName，不够灵活 */ if(token.getUserID()!=null&&token.getPassword()!=null){ User user=(User)this.getDao().executeQueryUnique('User.loadByLoginName', QueryCmdType.QUERY_NAME, token.getUserID()); String password=token.getPassword(); if(this.passwordEncoder!=null){ password=this.passwordEncoder.encodePassword(password, null); } if(!password.equalsIgnoreCase(user.getPassword())){ token.setErrCode('2'); return null; } if( token.isEnablePasscard() && usePassCard ){//token中激活密码卡且系统使用密码卡 int position1=((token.getRow1()-1)*7)+token.getColumn1(); int position2=((token.getRow2()-1)*7)+token.getColumn2(); //System.out.println( '---pos:'+position1+'---'+position2 ); if(user.getPassCardId()==null){ token.setErrCode('10'); return null; } PassCard passcard=this.passCardDao.findById(user.getPassCardId(), false); if(passcard==null||passcard.getStatus()==PassCardHelper.STATUS_CANCEL ){ token.setErrCode('10'); return null; } if(passcard.getConfusedContent()==null || passcard.getConfusedContent().length()<7*7*32 ){ token.setErrCode('10'); return null; } String content=passcard.getConfusedContent(); int perLen=content.length()/49; String str1=content.substring((position1-1)*perLen, position1*perLen); String str2=content.substring((position2-1)*perLen, position2*perLen); String inputStr1=token.getCard1(); String inputStr2=token.getCard2(); if(this.passwordEncoder!=null){ inputStr1 = md5.getMD5ofStr(md5.getMD5ofStr(inputStr1)); inputStr2 = md5.getMD5ofStr(md5.getMD5ofStr(inputStr2)); } if((!str1.equalsIgnoreCase(inputStr1))||(!str2.equalsIgnoreCase(inputStr2))){ token.setErrCode('10'); return null; } } user.setLastIp(token.getIp()); user.setLastLogin(new Date()); this.getDao().saveOrUpdate(user); user.setAuthenticated(true); /* * 导入一次角色权限，并且把权限set到User中，用于spring验证用户权限(getAuthorities方法) */ List<UserRole> userRoles=(List<UserRole>)this.getDao().executeQueryList('UserRole.listRoleByUserID', QueryCmdType.QUERY_NAME, -1, -1, user.getId()); Set<GrantedAuthority> accesses=new HashSet<GrantedAuthority>(); for(UserRole ur:userRoles){ accesses.add(ur.getRole()); } user.getOrg().getOrgName(); if(user.getOrg().getCertTypes()!=null) user.getOrg().getCertTypes().size();//延迟载入一下 user.setAccesses(accesses); return user; } return null; }

重写supports(Class<? extends Object> authentication)方法，authentication要

/** * 如果此处验证不通过，是不会执行authentication方法的 */ @Override public boolean supports(Class<? extends Object> authentication) { return authentication.equals(PassCardAuthenticationToken.class); }

4.定义filter，实现AbstractAuthenticationProcessingFilter的attemptAuthentication方法，用于获取在登录页面传递过来的参数，spring默认只获取userName(j_username)，password(j_username)，而且实现UserDetailsService时只传递username

import java.io.IOException;import java.util.Date;import javax.servlet.ServletException;import javax.servlet.http.Cookie;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;import org.apache.log4j.Logger;import org.springframework.security.core.Authentication;import org.springframework.security.core.AuthenticationException;import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;import org.springframework.util.StringUtils;import cn.edu.jszg.cert.user.UserLog;import cn.edu.jszg.cert.user.UserLogService;import cn.edu.jszg.cert.web.WebApplicationConfiguration;import cn.edu.jszg.cert.web.controller.portal.auth.RemoteDataValidator;import com.google.code.kaptcha.servlet.KaptchaServlet;public class PasscardAuthenticationProcessingFilter extends AbstractAuthenticationProcessingFilter { private String successPage = '/home/admin/index'; private String failurePage = '/public/adminLoginEntry'; private boolean forward = false; private boolean useVerifyCode=true; private String certLoginUrl; static Logger logger = Logger.getLogger(PasscardAuthenticationProcessingFilter.class); private WebApplicationConfiguration config; private UserLogService userLogService; public void setConfig(WebApplicationConfiguration config) { this.config = config; } /** * 实现AbstractAuthenticationProcessingFilter的有参构造 * 没记错的话，相当于该filter的访问路径 */ protected PasscardAuthenticationProcessingFilter() { super('/adminLoginCheck'); } public void setUseVerifyCode(boolean useVerifyCode) { this.useVerifyCode = useVerifyCode; } public void setUserLogService(UserLogService userLogService) { this.userLogService = userLogService; } public boolean validate(HttpServletRequest request) { String userId = request.getParameter('username'); String md2 = request.getParameter('m'); String l = request.getParameter('l'); if (userId == null || md2 == null || l == null) { return false; } long longTime = Long.parseLong(l); if (longTime < new Date().getTime()) { return false; } try { String md1 = RemoteDataValidator.genExamMd5Digest(userId, longTime); if (md1.equals(md2)) return true; } catch (Exception e) { //e.printStackTrace(); } return false; } /** * 可以通过request获取页面传递过来的参数，并且set到相应的token中 */ @Override public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException { // logger.warn('-----------------start证书登录用户----------'); HttpSession s = request.getSession(true); PassCardAuthenticationToken token = new PassCardAuthenticationToken(); String verifyCode = request.getParameter('verifyCode'); String userID = request.getParameter('username'); //....此处省略获取参数，并且验证、赋值的逻辑 Authentication auth = null; try { //此处调用getAuthenticationManager的authenticate方法，当supports方法返回true时执行authenticate方法 auth = this.getAuthenticationManager().authenticate(token); //此处为登录成功后，相应的处理逻辑 if (auth == null || !auth.isAuthenticated()) { s.setAttribute('__login_error', token.getErrCode()); } else { s.removeAttribute('__login_error'); s.removeAttribute('__login_username'); s.removeAttribute('__cert_userid'); if( token.isEnablePasscard()) { s.removeAttribute('__passcard_row1'); s.removeAttribute('__passcard_row2'); s.removeAttribute('__passcard_column1'); s.removeAttribute('__passcard_column2'); } } } catch (AuthenticationException e) { s.setAttribute('__login_error', token.getErrCode()); throw e; } return auth; } public void setSuccessPage(String successPage) { this.successPage = successPage; } public void setFailurePage(String failurePage) { this.failurePage = failurePage; } public void setForward(boolean forward) { this.forward = forward; } public void setCertLoginUrl(String certLoginUrl) { this.certLoginUrl = certLoginUrl; } @Override public void afterPropertiesSet() { super.afterPropertiesSet(); /* *该处理器实现了AuthenticationSuccessHandler, AuthenticationFailureHandler *用于处理登录成功或者失败后，跳转的界面 */ AuthenticationResultHandler handler = new AuthenticationResultHandler(); handler.setForward(forward); handler.setLoginFailurePage(failurePage); handler.setLoginSuccessPage(successPage); handler.setCertLoginUrl(certLoginUrl); //设置父类中的处理器 this.setAuthenticationSuccessHandler(handler); this.setAuthenticationFailureHandler(handler); }}

最后为spring-security配置文件中的配置，需要添加authentication-provider的引用，和filter的配置

<security:authentication-manager alias='authenticationManager'>  <security:authentication-provider ref='acocunt_defaultAnthentiactionProvider'/> <security:authentication-provider ref='registrationService'/> <security:authentication-provider ref='enrollmentService'/> <security:authentication-provider ref='userService'/> </security:authentication-manager> <bean class='cn.edu.jszg.cert.security.PasscardAuthenticationProcessingFilter'> <property name='authenticationManager' ref='authenticationManager'/> <property name='useVerifyCode' value='true'/> <property name='failurePage' value='/portal/home/auth/'></property> <property name='config' ref='webAppConfig'/> <property name='userLogService' ref='userLogService' /> <property name='certLoginUrl' value='${cert.login.url}'/> </bean>

还要在http中添加<security:custom-filter ref='passcard_filter' after='SECURITY_CONTEXT_FILTER'/>
