SpringBoot配置全局的异常捕获-web页面跳转

一定义控制器

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";
    }
    
}

二定义错误处理类

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();

        ModelAndView mav = new ModelAndView();
        mav.addObject("exception", e);
        mav.addObject("url", reqest.getRequestURL());
        mav.setViewName(IMOOC_ERROR_VIEW);
        return mav;
    }
    
}

三定义错误页面模板

<!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>
