a、针对500异常的统一处理

1、实现HandlerExceptionResolver，重写resolveException方法

package com.liying.mango.common.interceptor;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.log4j.Logger;import org.springframework.web.servlet.HandlerExceptionResolver;import org.springframework.web.servlet.ModelAndView;/** * 异常信息统一处理器 * * @author jqlin */public class MyExceptionHandler implements HandlerExceptionResolver {    private static final Logger log = Logger.getLogger(MyExceptionHandler.class);    @Override    public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response,             Object obj, Exception e) {        //堆栈信息打印到错误的日志文件中        log.error(e.getMessage(), e);                //跳转到500页面        return new ModelAndView("500");      }}

 

2、最后，将HandlerExceptionResolver实现类配置到Spring配置文件中

 

b、针对404异常的统一处理

web.xml 404配置

             
      
       404
              
      
       /page/404.jsp
