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。
以上这篇解决Springboot @WebFilter拦截器未生效问题就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持自学编程网。
