为什么在action中定义页面属性就能获取到值，但是像这样分开后就拿不到值了呢？求解.
------解决方案--------------------------------------------------------
public class LoginActionForm extends ActionSupport{
User us = new User();//不需要new User 为us生成getter和setter方法
public String execute(){
System.out.println("username:"+us.getUserName());
System.out.println("password:"+us.getPassWord());
return SUCCESS;
}
}
<s:form action="login" method="post">
<s:textfield name="UserName" label="用户名"></s:textfield>// name=us.UserName
<s:password name="PassWord" label="密码"></s:password> // name=us.PassWord
