spring boot 2.0+ 自定义配置404、500页面

 

1.新建controller类：MyErrorController

package com.example.meeting.controller;

import org.springframework.boot.web.servlet.error.ErrorController;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;

@Controller
public class MyErrorController implements ErrorController {

    @RequestMapping("/error")
    public String handleError(HttpServletRequest request){
        //获取statusCode:401,404,500
        Integer statusCode = (Integer) request.getAttribute("javax.servlet.error.status_code");
        if(statusCode == 401){
            return "/error/401";
        }else if(statusCode == 404){
            return "/error/404";
        }else if(statusCode == 403){
            return "/error/403";
        }else{
            return "/error/500";
        }

    }
    @Override
    public String getErrorPath() {
        return "/error";
    }
}

 

2.将500.html、404.html放在相应文件夹下：

 

 

3.显示效果，随便输入一个不存在的界面：
