Springmvc异常处理器及拦截器实现代码

Springmvc异常处理器及拦截器实现代码

一、异常处理器

1、实现HandlerExceptionResolver接口

package com.wuxi.exceptions;

import org.springframework.web.servlet.HandlerExceptionResolver;

import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class RequestExceptionResolver implements HandlerExceptionResolver {

@Override

public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {

ModelAndView mv = new ModelAndView();

mv.addObject("errorMsg", e.getMessage());//错误信息

mv.setViewName("error");//请求转发的页面

return mv;

}

}

2、springmvc的xml配置文件

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xmlns:context="http://springframework.org/schema/context"

xmlns:mvc="http://springframework.org/schema/mvc"

xsi:schemaLocation="http://springframework.org/schema/beans

https://springframework.org/schema/beans/spring-beans.xsd

http://springframework.org/schema/context

https://springframework.org/schema/context/spring-context.xsd

http://springframework.org/schema/mvc

https://springframework.org/schema/mvc/spring-mvc.xsd">

</bean>

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xmlns:context="http://springframework.org/schema/context"

xmlns:mvc="http://springframework.org/schema/mvc"

xsi:schemaLocation="http://springframework.org/schema/beans

https://springframework.org/schema/beans/spring-beans.xsd

http://springframework.org/schema/context

https://springframework.org/schema/context/spring-context.xsd

http://springframework.org/schema/mvc

https://springframework.org/schema/mvc/spring-mvc.xsd">

</bean>
