SpringMVC中的异常处理 - JAVA

这是个WebProject，用到的是spring-framework-3.1.1.RELEASE

首先是web.xml
[html] < xml version="1.0" encoding="UTF-8" >
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

user
org.springframework.web.servlet.DispatcherServlet
1

user
/

SpringCharacterEncodingFilter
org.springframework.web.filter.CharacterEncodingFilter

encoding
UTF-8

SpringCharacterEncodingFilter
/*

/WEB-INF/jsp/login.jsp

下面是用户登录页面//WEB-INF//jsp//login.jsp
[html]
<%@ page language="java" pageEncoding="UTF-8"%>

下面是用户登录失败页面//WEB-INF//jsp//error.jsp
[html]
<%@ page language="java" pageEncoding="UTF-8"%>
${myex.message}

下面是用户登录成功页面//WEB-INF//jsp//user//loginSuccess.jsp
[html]
<%@ page language="java" pageEncoding="UTF-8"%>
welcome: ${loginUser.nickname}

接下来是用到的实体类User.java
[java]
package com.jadyer.model;

/**
* User
* @author 宏宇
* @create May 12, 2012 1:24:43 AM
*/
public class User {
private String username;
private String nickname;
private String password;
private String email;
/*==四个属性的getter()、setter()略==*/
public User() {}
public User(String username, String nickname, String password, String email) {
this.username = username;
this.nickname = nickname;
this.password = password;
this.email = email;
}
}

然后是自定义的异常类UserException.java
[java]
package com.jadyer.exception;

/**
* UserException
* @author http://blog.csdn/net/jadyer
* @create May 12, 2012 6:43:29 PM
*/
@SuppressWarnings("serial")
public class UserException extends RuntimeException {
public UserException() {
super();
}

public UserException(String message, Throwable cause) {
super(message, cause);
}

public UserException(String message) {
super(message);
}

public UserException(Throwable cause) {
super(cause);
}
}

最后是核心的UserController.java
[java]
package com.jadyer.controller;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.Req
