org.hibernate.MappingException는 알 수없는 엔티티는 spring4

Question

나는 예외를 얻고있다 org.hibernate.MappingException을 hibernate4 : 알 수없는 엔티티를 com.pro.entity.User

내가 유사한 게시물을 보았다 그러나 거의 모두가 솔루션을 제공합니다 @Entity 어노테이션을 Hibernate 대신 javax.persistence로 변경합니다. 필자는 처음부터 정확한 주석을 사용하고 있기 때문에 유용하지 않았다. 엔티티 클래스 dao와 서블릿 컨텍스트에 대한 코드는 다음과 같습니다.

package com.pro.entity; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.Table; 

@Entity 
@Table(name="user") 
public class User { 

    private static final long serialVersionUID = 1L; 


    @Id 
    @Column(name="userid") 
    @GeneratedValue(strategy=GenerationType.IDENTITY) 
    private String id; 

    @Column(name="password") 
    private String password; 

    public String getId() { 
     return id; 
    } 

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

    public String getPassword() { 
     return password; 
    } 

    public void setPassword(String password) { 
     this.password = password; 
    } 

    } 

다오 클래스 코드 :

public User getUser(String userid) 
{ 

     Session session = this.sessionFactory.getCurrentSession(); 

     User user = (User)session.load(User.class, userid); 

     return user; 

    }

Answer 1

chnage <context:component-scan base-package="com.pro.controller" /> 의 context.xml에서 <context:component-scan base-package="com.pro" /> 에

는 그 다음

작동합니다

Answer 2

감사합니다. 난 그냥 당신이 어딘가에 비밀 최대 절전 모드 설정을하지 않는 한, Hibernate는 당신의 실체에 대해 아무것도 모르는

<beans:property name="annotatedClasses"> 
      <beans:list> 
       <beans:value>com.pro.User</beans:value> 
      </beans:list> 
     </beans:property>
