org.hibernate.QueryParameterException

我是春季新手。我試圖通過彈簧執行添加，刪除，編輯數據庫操作和hibernate.delete和添加操作已成功執行，但當我試圖編輯通過單擊編輯。我得到這個錯誤：org.hibernate.QueryParameterException

全堆棧跟蹤：

控制器類：「userController.java」

@Controller 
public class userController { 

@Autowired 
private userService userService; 

@RequestMapping("/user") 
public String listUser(Map<String, Object> map) { 
    map.put("user", new User()); 
    map.put("userList", userService.listUser()); 
    return "user"; 
} 

@RequestMapping(value = "/addUser",method = RequestMethod.POST) 
public String addUser(@ModelAttribute("user")User user, BindingResult result) 
{ 
    if(null == user.getId()) { 
     userService.addUser(user);  
    } 
    else { 
     userService.updateUser(user); 
    } 
    return "redirect:/user"; 
} 

@RequestMapping("/delete/{userId}") 
public String deleteUser(@PathVariable("userId") Integer userId) 
{ 
    userService.deleteUser(userId); 
    return "redirect:/user"; 
} 

@RequestMapping("/edit/{userId}") 
public String edit(@PathVariable("userId")Integer userId,Map<String, Object> map) 
{ 
    map.put("user", userService.getUserById(userId)); 
    map.put("userList", userService.listUser()); 
    return "user"; 
} 
}

Dao實施：「userDaoImpl.java」

@Repository 
public class userDaoImpl implements userDao { 

@Autowired 
private SessionFactory sessionFactory; 

@Override 
public void addUser(User user) { 
    sessionFactory.getCurrentSession().save(user); 
} 

@Override 
public void deleteUser(Integer id) { 
    User user = (User)sessionFactory.getCurrentSession().load(User.class,id); 
    if(null != user) { 
     sessionFactory.getCurrentSession().delete(user); 
    } 
} 

@Override 
@SuppressWarnings("unchecked") 
public List<User> listUser() { 
    return sessionFactory.getCurrentSession().createQuery("from User").list(); 
} 

@Override 
public void updateUser(User user) { 
    sessionFactory.getCurrentSession().update(user); 
} 

@Override 
@SuppressWarnings("unchecked") 
public User getUserById(Integer id) { 
    Session session = sessionFactory.getCurrentSession(); 
    List<User> list = session.createQuery("from User u where u.id = :id").setParameter("UserId",id).list(); 
    return list.size() > 0 ?(User)list.get(0): null; 
} 

public SessionFactory getSessionFactory() { 
    return sessionFactory; 
} 


public void setSessionFactory(SessionFactory sessionFactory) { 
    this.sessionFactory = sessionFactory; 
} 

}

'的setParameter（「ID」，ID）' – 2014-09-10 13:42:43

謝謝盧卡·巴索·裏奇。有效。 – bablu 2014-09-10 13:52:56

需要如下改變

List<User> list = session.createQuery("from User u where u.id = :id").setParameter("id",id).list();
