Struts2通过json前后台传数据的问题

Question

bean如下

public class User implements Serializable
{
    private static final long serialVersionUID = 9093919302451530682L;
    private String name;
    private String password;
}

 前台传得json格式如下

var date={
             "userName":"1111",
             "password":"2222",
             "user":{
                 "name":"3333",
                 "password":"4444"
             }
     };

 action里

 
public class LoginAction implements Action
{
     private User user;
     private String userName;
     private String password;
     public String execute() throws Exception
    {
        System.out.println(userName);
        //userName值"1111"
        System.out.println(password);
        //password值"2222"
        System.out.println(user.toString());
        //user对象为null，这里怎么获取json对象并转User对象     
        return Action.SUCCESS;
      
    }
}

 json的jar包有：

 json-lib-2.4-jdk15.jar

 jsonplugin-0.34.jar

你前台的json要组装成下面的格式，传入后台struts2才能被正确封装。
[code="javascript"]
var date={

"userName":"1111",

"password":"2222",

"user.name":"3333",

"user.password":"4444"
};
[/code]
