自定义拦截器


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;@Component
public class TimeInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)throws Exception {System.out.println("prehandle");return true;}@Overridepublic void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,ModelAndView modelAndView) throws Exception {System.out.println("postHandle");}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)throws Exception {System.out.println("afterCompletion");}
}

自定义WebConfig

@Configuration
public class WebConfig implements WebMvcConfigurer {//WebMvcConfigurer接口的方式，而不用使用WebMvcConfigurerAdapter @Autowiredprivate TimeInterceptor timeInterceptor;//自定义的拦截器，标注为@compent已经注入带bean中@Overridepublic void addInterceptors(InterceptorRegistry registry) {//registry.addInterceptor(timeInterceptor).addPathPatterns("/user");;//添加登录处理拦截器，拦截所有请求，登录请求除外InterceptorRegistration interceptorRegistration = registry.addInterceptor(timeInterceptor);//排除配置/*interceptorRegistration.excludePathPatterns("/sys/login.json");interceptorRegistration.excludePathPatterns("/charts/**");interceptorRegistration.excludePathPatterns("/css/**");interceptorRegistration.excludePathPatterns("/easyUi/**");interceptorRegistration.excludePathPatterns("/flashPlayer/**");interceptorRegistration.excludePathPatterns("/font/**");interceptorRegistration.excludePathPatterns("/images/**");interceptorRegistration.excludePathPatterns("/js/**");interceptorRegistration.excludePathPatterns("/pages/**");interceptorRegistration.excludePathPatterns("/plugin/**");interceptorRegistration.excludePathPatterns("/index.html");interceptorRegistration.excludePathPatterns("/show.html");*///配置拦截策略interceptorRegistration.addPathPatterns("/**");}/*    @Beanpublic FilterRegistrationBean timeFilter() {FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();TimeFilter TimeFilter = new TimeFilter();filterRegistrationBean.setFilter(TimeFilter);List<String> url = new ArrayList<String>();url.add("/*");filterRegistrationBean.setUrlPatterns(url);return filterRegistrationBean;}*/}
