1.在jsp标签上添加属性isErrorPage=“true”

<%@ page language="java" contentType="text/html; charset=UTF-8" 
pageEncoding="UTF-8" isErrorPage="true" %>

2.借用重定向

重新写一个执行success的方法，返回时先重定向到该方法
@RequestMapping(value = "/user",method = RequestMethod.DELETE)public String del(String id){System.out.println("del......."+id);return "redirect:/tosuccess";}
@RequestMapping("/tosuccess")public String test(){return "success";}
