問題描述

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

未生效攔截器

解決方法

在springboot啟動(dòng)類上添加

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

路徑替換為@WebFilter所在包

補(bǔ)充知識(shí)：在spring boot中使用@WebFilter配置filter（包括排除URL）

我就廢話不多說了，大家還是直接看代碼吧~

@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('這里是不需要處理的url進(jìn)入的方法'); chain.doFilter(req, res); } else { System.out.println('這里是需要處理的url進(jìn)入的方法'); } } @Override public void destroy() { System.out.println('destroy----------filter'); }}

@Order中的value越小，優(yōu)先級(jí)越高。

以上這篇解決Springboot @WebFilter攔截器未生效問題就是小編分享給大家的全部內(nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
