1.先定义拦截器的文件内容，如interceptor/BingInterCeptor
public class BingInterCeptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { String path = request.getServletPath(); if(path.matches(".*/((.css)|(.js)|(images)|(login)|(anon)).*")){ return true; }else{ System.out.println("这里开始拦接"); System.out.println(request.getSession()); System.out.println(request.getQueryString()); System.out.println(request.getRequestURI()); System.out.println(request.getRequestURL()); System.out.println(request.getPathInfo()); return false; } // return false; }
2.再在配置文件夹中定义配置类,就可以使用了
@Configuration public class WebConfig implements WebMvcConfigurer { @Override public void addInterceptors(InterceptorRegistry registry) {
InterceptorRegistration loginRegistry = registry.addInterceptor(bingInterCeptor()).addPathPatterns("/**"); //拦截所有请求
// 排除路径
loginRegistry.excludePathPatterns("/login");
loginRegistry.excludePathPatterns("/loginout");
loginRegistry.excludePathPatterns("/view/toLogin");
loginRegistry.excludePathPatterns("/view/toReg");
loginRegistry.excludePathPatterns("/user/UserReg");
loginRegistry.excludePathPatterns("/static/user/css/*.css");
loginRegistry.excludePathPatterns("/static/user/js/*.js");
loginRegistry.excludePathPatterns("/static/user/images/*");
} @Bean public BingInterCeptor bingInterCeptor(){ return new BingInterCeptor(); } }
