springmvc如何进行异常处理

1.异常处理

1.1局部处理(直接写在处理器中)

    @ExceptionHandler
    public ModelAndView error(Exception exception) {
        ModelAndView mv = new ModelAndView();
        mv.addObject("error", exception.getMessage());
        mv.setViewName("forward:../error.jsp");
        return mv;
    }

1.2全局处理（新建一个类，用来接收获得的所有的异常，以此避免在每一个类中进行异常处理）

代码如下：

package com.zhiyou100.wyf.controller;

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

@ControllerAdvice
public class ExceptionController {

    @ExceptionHandler
    public ModelAndView error(Exception exception) {
        ModelAndView mv = new ModelAndView();
        mv.addObject("error", exception.getMessage());
        mv.setViewName("forward:../error.jsp");
        return mv;
    }
    
}

jsp页面：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8" isErrorPage="true" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script type="text/javascript"></script>
</head>
<body>
${error }
</body>
</html>
