package com.ls.action;


import com.ls.entity.User;

import com.opensymphony.xwork2.ActionSupport;

import com.opensymphony.xwork2.ModelDriven;


public class LoginAction extends ActionSupport implements ModelDriven<User>{


private static final long serialVersionUID = 2420947456421303802L;

private User user =new User();

public String login() {

if(user.getUsername()==null || " ".equals(user.getUsername())){

this.addFieldError("username", "姓名不能为空");

return INPUT;

}

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

System.out.println(user.getBookList().get(0).getUsername());

System.out.println(user.getBookList().get(1).getUsername());

return SUCCESS;

}


@Override

public User getModel() {

// TODO Auto-generated method stub

return user;
