struts2如何将jsp页面中的一个值传到pojo中的一个属性中去.(属性是对象类型的)
public User{
private String userid;
private String password;
private Classes classes;//班级
//getter and setter
......
}

public Classes {
private String classesid;
private String classesname;
private Major major;//专业
//getter and setter
......
}

public TestAction extends ActionSupport{
private UserService us;
private User user;
public String execute() throws Exception{
us.inser(user);
}
}

//jsp页面
<s:textfiled name="user.userid"/>
<s:textfiled name="user.password"/>
<s:textfiled name="user.classes.classesid"/>

jsp页面提交后,如何能将classesid的值传给user对象中的classes属性呢,并且将classes完全初始化呢?
