实现HandlerExceptionResolver

import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;

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

//全局异常
@Component
public class GlobleException implements HandlerExceptionResolver {

    @Override
    public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("500");
        modelAndView.addObject("message",e.getMessage());
        return modelAndView;
    }
}

开发一个500.jsp的页面

程序中一旦出现异常就会跳转到500.jsp页面

<%@page contentType="text/html; UTF-8" pageEncoding="UTF-8" isELIgnored="false" %>
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>

    <h1>服务器出现异常，异常信息为：${requestScope.message}</h1>

</body>
</html>
