id to load is required for loading

由于update时没有传到值
在action中

	private Long id;

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public void update(Long id, String username, String password) {
		User user = userDao.findUserById(id);
		user.setUsername(username);
		user.setPassword(password);
		userDao.update(user);
	}

	public void updateRedirect(Long id) {
		user = userDao.findUserById(id);
		
	};

public class UpdateUserAction{
	private Long usersid;
	private String username;
	private String password;
public Long getUsersid() {
		return usersid;
	}
	public void setUsersid(Long usersid) {
		this.usersid = usersid;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
public String execute() {
	 
	 UserServiceImpl userService=new UserServiceImpl();
	  userService.updateService(usersid, username, password);
	  return "allUsers";
  }
}
