解决Springboot @WebFilter拦截器未生效问题

问题描述

@WebFilter(filterName = “ssoFilter”,urlPatterns = “/*”)

未生效拦截器

解决方法

在springboot启动类上添加

@ServletComponentScan(basePackages = “full.package.path”)

路径替换为@WebFilter所在包

补充知识：在spring boot中使用@WebFilter配置filter（包括排除URL）

我就废话不多说了，大家还是直接看代码吧~

@WebFilter(urlPatterns = '/*')@Order(value = 1)public class TestFilter implements Filter { private static final Set<String> ALLOWED_PATHS = Collections.unmodifiableSet(new HashSet<>( Arrays.asList('/main/excludefilter', '/login', '/logout', '/register'))); @Override public void init(FilterConfig filterConfig) throws ServletException { System.out.println('init-----------filter'); } @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; HttpServletResponse response = (HttpServletResponse) res; String path = request.getRequestURI().substring(request.getContextPath().length()).replaceAll('[/]+$', ''); boolean allowedPath = ALLOWED_PATHS.contains(path); if (allowedPath) { System.out.println('这里是不需要处理的url进入的方法'); chain.doFilter(req, res); } else { System.out.println('这里是需要处理的url进入的方法'); } } @Override public void destroy() { System.out.println('destroy----------filter'); }}

@Order中的value越小，优先级越高。
