SpringBoot配置全局的异常捕获——同时兼容Web和ajax

一控制器

package com.imooc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.imooc.pojo.IMoocJSONResult;

@Controller
@RequestMapping("err")
public class ErrorController {

    @RequestMapping("/error")
    public String error() {
        
        int a = 1 / 0;
        
        return "thymeleaf/error";
    }
    
    @RequestMapping("/ajaxerror")
    public String ajaxerror() {
        
        return "thymeleaf/ajaxerror";
    }
    
    @RequestMapping("/getAjaxerror")
    @ResponseBody
    public IMoocJSONResult getAjaxerror() {
        
        int a = 1 / 0;
        
        return IMoocJSONResult.ok();
    }
}

二统一错误处理类

package com.imooc.exception;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.servlet.ModelAndView;

import com.imooc.pojo.IMoocJSONResult;

@ControllerAdvice
public class IMoocExceptionHandler {

    public static final String IMOOC_ERROR_VIEW = "error";
    
    @ExceptionHandler(value = Exception.class)
    public Object errorHandler(HttpServletRequest reqest,
            HttpServletResponse response, Exception e) throws Exception {

        e.printStackTrace();

        if (isAjax(reqest)) {
            return IMoocJSONResult.errorException(e.getMessage());
        } else {
            ModelAndView mav = new ModelAndView();
            mav.addObject("exception", e);
            mav.addObject("url", reqest.getRequestURL());
            mav.setViewName(IMOOC_ERROR_VIEW);
            return mav;
        }
    }

    /**
     *
     * @Title: IMoocExceptionHandler.java
     * @Package com.imooc.exception
     * @Description: 判断是否是ajax请求
     * Copyright: Copyright (c) 2017
     * Company:FURUIBOKE.SCIENCE.AND.TECHNOLOGY
     */
    public static boolean isAjax(HttpServletRequest httpRequest){
        return  (httpRequest.getHeader("X-Requested-With") != null
                    && "XMLHttpRequest"
                        .equals( httpRequest.getHeader("X-Requested-With").toString()) );
    }
}

三错误页模板定义

1 error.html

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8" />
    <title>捕获全局异常</title>
</head>
<body>
    <h1 style="color: red">发生错误：</h1>
    <div th:text="${url}"></div>
    <div th:text="${exception.message}"></div>
</body>
</html>

2 ajaxerror.html

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8" />
    <title>捕获全局异常</title>
</head>
<body>
    <h1 style="color: red">发生错误：</h1>
    <div th:text="${url}"></div>
    <div th:text="${exception.message}"></div>
</body>
</html><!DOCTYPE html >
<html>
<head lang="en">
    <meta charset="UTF-8" />
    <title></title>
    
    <script th:src="@{/static/js/jquery.min.js}"></script>
    
</head>
<body>

<h1>测试ajax错误异常</h1>

<script th:src="@{/static/js/ajaxerror.js}"></script>
</body>
</html>

四 Ajax程序

$.ajax({
        url: "/err/getAjaxerror",
        type: "POST",
        async: false,
        success: function(data) {
            debugger;
            if(data.status == 200 && data.msg == "OK") {
                alert("success");
            } else {
                alert("发生异常：" + data.msg);
            }
        },
        error: function (response, ajaxOptions, thrownError) {
            debugger;
            alert("error");       
        }
    });

五测试

1 输入：http://localhost:8080/err/ajaxerror
