Hibernate는 DB에 데이터를 저장하지 않습니까?

Question

나는 세부 사항을 입력하는 양식이 있지만 저장을 클릭하면 데이터베이스에 저장되지 않는다 ... 테이블이 생성 되더라도.

내 연락 POJO

package your.intermedix.domain; 

import java.io.Serializable; 

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

@Entity 
@Table(name="USER") 

public class Contact implements Serializable { 

    private static final long serialVersionUID = 1L; 

    private Long id; 
    private String name; 
    private String email; 
    private String lastname; 
    private String designation; 

    @Id 
    @GeneratedValue 
    @Column(name="USER_ID") 
    public Long getId() { 
     return id; 
    } 

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

    @Column(name="DESIGNATION") 
    public String getDesignation(){ 
     return designation; 
    } 

    public void setDesignation(String designation){ 
     this.designation = designation; 
    } 

    @Column(name="EMAIL") 
    public String getEmail(){ 
     return email; 
    } 

    public void setEmail(String email){ 
     this.email = email; 
    } 

    @Column(name="LASTNAME") 
    public String getLastname(){ 
     return lastname; 
    } 

    public void setLastname(String lastname){ 
     this.lastname= lastname; 
    } 

    @Column(name="FIRSTNAME") 
    public String getName(){ 
     return name; 
    } 

    public void setName(String name){ 
     this.name = name; 
    } 


    public String toString() 
    { 
     return "designation = '" + designation + "',email='"+ email +"', lastname='"+ lastname +"', name = '" + name + "'"; 
    } 

}

Answer 1

작동

package your.intermedix.services; 

import org.hibernate.SessionFactory; 

import org.springframework.orm.hibernate3.HibernateTemplate; 
import org.springframework.stereotype.Service; 

import your.intermedix.domain.Contact; 
import your.intermedix.services.IContact; 

@Service 
public class ContactSerImpl implements IContact { 

    private HibernateTemplate hibernateTemplate; 

     public void setSessionFactory(SessionFactory sessionFactory) { 
      this.hibernateTemplate = new HibernateTemplate(sessionFactory); 
    } 
      @Transactional 
     public void saveContact(Contact contact) { 
      System.out.println("Hello Guru contact"); 
      System.out.println(contact); 
      hibernateTemplate.saveOrUpdate(contact); 
     } 

     public void hello() { 
      System.out.println("Hello Guru"); 
     } 
} 

내 서비스 클래스 아니 databackend에 flushed. 당신에게주는 것은

System.err.println(hibernateTemplate.getFlushMode()); 

Answer 2

실행 트랜잭션이 필요합니다. HibernateTemplate을 사용하는 경우 Spring transaction management을 사용할 수 있습니다. 설명서를 읽으십시오. 이 답변에 포함하는 데 시간이 너무 오래지만, 여기에 짧은에 : 당신은 당신이 <tx:annotation-driven />

당신이 @Transactional과의 거래 방법에 주석을해야 할 필요가

스프링 빈으로 트랜잭션 관리자를 정의 할 필요가
