Spring Security学习笔记（一）

介绍

这里学习SpringSecurity，对SpringSecurity进行学习。

基本用法

添加依赖

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId></dependency>

添加接口

package com.example.demo.web;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping('/test')public class Test { @RequestMapping('/test') public String test(){ return 'test'; }}

启动项目

可以看到日志中，已经有了密码

访问接口，此时已经有了登录页面

输入用户名和密码

用户名： user密码 984cccf2-ba82-468e-a404-7d32123d0f9c

此时已经登录成功

配置用户名和密码

在配置文件中，进行配置

spring:security:user:name: mingpassword: 123456roles: admin

输入用户名和密码，可以正常登录

基于内存的认证

需要自定义类继承 WebSecurityConfigurerAdapter实现自定义的配置这里基于内存的配置，如下

package com.example.demo.config;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;import org.springframework.security.crypto.password.NoOpPasswordEncoder;import org.springframework.security.crypto.password.PasswordEncoder;@Configurationpublic class MyWebSecurityConfig extends WebSecurityConfigurerAdapter { @Bean PasswordEncoder passwordEncoder(){ return NoOpPasswordEncoder.getInstance(); } @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication().withUser('admin').password('123').roles('admin'); }}

这里基于内存的配置

HttpSecurity

这里对某些方法进行拦截

package com.ming.demo.interceptor;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.http.HttpMethod;import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;import org.springframework.security.crypto.password.PasswordEncoder;import org.springframework.security.web.authentication.rememberme.TokenBasedRememberMeServices;@Configuration@EnableWebSecuritypublic class SecurityConfig extends WebSecurityConfigurerAdapter { //基于内存的用户存储 @Override public void configure(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication().withUser('itguang').password('123456').roles('USER').and().withUser('admin').password('{noop}' + '123456').roles('ADMIN'); } //请求拦截 @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests().anyRequest().permitAll().and().formLogin().permitAll().and().logout().permitAll(); }}

这里成功完成了post请求进行登录验证。
