Question

ajax提交json时action接收不到对象数据但是能接收到action的单个属性

action的配置
<package name="useracton" namespace="/" extends="json-default">
<action name="login" class="userAction" method="login" >
<result>/index.jsp</result>
<result name="error" type="json">
<param name="root">msg</param>
</result>
</action>
</package>

var datas = {"user.userName":userName,"user.passWord":loginPwd,"msg":"好"}
alert(userName);
$.ajax({
url:"login.action",
data:datas,
dataType:"json",
type:"post",
error: function(data){
if(data.msg=="false"){
}
}
});
action类
@Controller("userAction")
public class UserAction extends ActionBase {
private static final long serialVersionUID = 6768226878085889112L;
private Users user;
private String msg = null;
public String login(){
System.out.println(msg);
System.out.println(user.getuserName()+"23");
for(Users user2:list){
if(user2.getpassWord().equals(user.getpassWord())){
user = user2;
session.put("loginUser", user);
return SUCCESS;
}
}
msg = "false";
return ERROR;
}

/////////////////getter和setter方法////////////////////////////////
public Users getUser() {
return user;
}
public void setUser(Users user) {
this.user = user;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}

}
msg能收到数据但是user.userName却等null这是怎么回事?
