AccountAction.java



public @Getter @Setter class AccountAction extends ActionSupport implements ModelDriven<Person> {

	private Person person=new Person();

	private final String ERROR404="error404";

	private final String FORMAL="formal";

	private final String INDEX="index";

	

//	用于上一个链接

	private String previousHref=ServletActionContext.getRequest().getHeader("Referer");

	

	

	@Resource(name="userManagerImp")

	private UserManager userManger;

	



	

//	登录

	public String login(){

		if(isUserAlreadyLogin(ServletActionContext.getRequest()))

			return INDEX;

		if(userManger.findUserByEmailAndPassword(person.getEmail(), person.getPassword())==null){

			System.out.println("登录失败"+person.getEmail()+person.getPassword());	

			return FORMAL;

		}

		if( previousHref!= null)

			return SUCCESS;

           storeEmailAtCookieWithSession(person.getEmail());

		System.out.println("登录成功");	

		return INDEX;

	}

	

	

	

	/**再次判断用户注册是否出错 

	 * */

	private boolean isWrongWithPerson(){

		return person.getEmail()==null||person.getPassword().equals("")||person.getName().equals("")||

				userManger.checkUserExistByEmail(person.getEmail());

	}

	

	

	

	

	@Override

	public Person getModel() {

		return person;

	}

	

	

}

Person



private long id;

	

	private String name;

	private String email;

	private String password;

	private String description;



getter setter

结果是：
nullnull
Hibernate:
select
user0_.id as id4_,
user0_.headPhoto_id as headPhoto2_4_,
user0_.personInfor_id as personIn3_4_
from
User user0_,
Person person1_
where
user0_.personInfor_id=person1_.id
and person1_.email=?
and person1_.password=?
登录失败nullnull

为什么太奇怪啦
