请教struts2接收参数的问题

oodick 2010-02-06 06:05:47

我想通过前台页面给后台传递一个数组，我使用传统的html页面写checkbox 然后后台使用ModelDriven模式就可以成功接受

但是我测试使用DoaminModel方式接受就不行



public class UserAction4 extends ActionSupport{

	

	private User user ; 

	

	private UserServices userServices;



	public String addUser()throws Exception{

		System.out.println("addUser() 被调用");

		System.out.println(user.getPassword());

		System.out.println(user.getUsername());

		String [] tmp = user.getArrs();

		for (int i = 0; i < tmp.length; i++) {

			System.out.print(tmp[i]);

		}

		System.out.println(user.getList());

		return "success";

	}

	

	public String delUser(){

		System.out.println("delUser() 被调用");

		

		return Action.SUCCESS;

	}

	

	

	public String updateUser(){

		System.out.println("updateUser()被调用");

		return Action.SUCCESS;

	}



	public void setUserServices(UserServices userServices) {

		this.userServices = userServices;

	}



	public User getUser() {

		return user;

	}



	public void setUser(User user) {

		this.user = user;

	}
