1.局部处理
2.定义一个全局变量
public class EcxeptionController { @ExceptionHandler public ModelAndView error(Exception exception) { ModelAndView mv=new ModelAndView(); mv.addObject("error",exception.getMessage()); mv.setViewName("error"); return mv; } }
3.定义一个错误页面
<%@ 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> </head> <body> ${error } </body> </html>
