springmvc怎样进行异常处理
人气:0异常处理
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; }
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>
