首先把SpringBoot默认的异常处理屏蔽掉:

spring:
  mvc:
    throw-exception-if-no-handler-found: true
  resources:
    add-mappings: false
server:
  error:
    whitelabel:
      enabled: false

如下代码, 其中401,403处理是配合shiro使用的, 当没有授权时,shiro指定 /error/403跳转

package com.ztdz.tmss.web.controller;

import org.springframework.http.HttpStatus;
import org.springframework.web.HttpMediaTypeNotSupportedException;
import org.springframework.web.HttpRequestMethodNotSupportedException;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.NoHandlerFoundException;

import javax.servlet.http.HttpServletResponse;
