SpringBoot添加拦截器

自定义拦截器

package com.company.interceptor;import lombok.extern.slf4j.Slf4j;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;@Slf4jpublic class MyInterceptor implements HandlerInterceptor {         @Override    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {        log.debug("preHandle method is running");        return true;    }    @Override    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {        log.debug("postHandle method is running");    }    @Override    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {        log.debug("afterCompletion method is running");    }}

写一个配置类

package com.company.config;import com.company.interceptor.MyInterceptor;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;@Configurationpublic class MvcConfig implements WebMvcConfigurer{    @Override    public void addInterceptors(InterceptorRegistry registry) {　　　　　//指定拦截器类　　　　　　　　　　　　　　　　　　　　//指定拦截路径        registry.addInterceptor(new MyInterceptor()).addPathPatterns("/**");    }}
