基于struts2的全局自定义类型转换器

实体bean的
package com.bean;

public class User {
	private  :arrow: String username;
	
	private String password;

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}
}


struts2.xml配置文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    <constant name="struts.enable.DynamicMethodInvocation" value="true" />
    <constant name="struts.devMode" value="true" />
    
    <package name="default" namespace="/main" extends="struts-default">
        <action name="struts2Index_*" class="com.struts2.action.Struts2ConverterAction" method="{1}" >
        	<result type="dispatcher">
        		/index.jsp
        	</result>
        </action>
    </package>
</struts>


控制器actin
package com.struts2.action;

import org.apache.log4j.Logger;

import com.bean.User;

public class Struts2ConverterAction {
	
	private static Logger logger = Logger.getLogger(Struts2ConverterAction.class);
	
	private User user;
	
	public String loginUser(){
		System.out.println(user.getUsername() + ":" + user.getPassword());
		return "success";
	}
	
	public User getUser() {
		return user;
	}
	
	public void setUser(User user) {
		this.user = user;
	}
	
}


注册器
package com.struts2.strutsconverter;

import java.util.Map;

import org.apache.struts2.util.StrutsTypeConverter;

import com.bean.User;

public class Struts2Converter extends StrutsTypeConverter {

	@Override
	public Object convertFromString(Map context, String[] values, Class toClass) {
		User user = new User();
		String[] strValue = values[0].split(",");
		user.setUsername(strValue[0]);
		user.setPassword(strValue[1]);
		return user;
	}

	@Override
	public String convertToString(Map context, Object o) {
		User user = (User)o;
		return user.getUsername() + "," + user.getPassword();
	}
	
}



试图jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  </head>
  
  <body>
    <form action="/StrutsTypeConverter/main/struts2Index_loginUser" method="post">
    	<input type="text" name="user" value="${user.username },${user.password }" />
    	<input type="submit" value="提交" />
    </form>
  </body>
</html>


最后配置注册器,在classpath目录下配置如下配置文件,文件名为固定格式:
xwork-conversion.properties
具体配置为:
com.bean.User=com.struts2.strutsconverter.Struts2Converter
