Hibernate : 엔티티가 persist() 함수에서 DB에 푸시되지 않았습니다.

Question

세계를 최대 절전 모드로 전환하고 데모 샘플을 준비하는 것이 좋습니다. 나는 entityManager.persist (엔티티) 함수를 사용해 보았다. 오류는 없지만 엔티티가 DB에 유지되지 않습니다.

여기 여기

package com.fks.nclp.junit; 

import java.math.BigDecimal; 

import javax.persistence.EntityManager; 
import javax.persistence.EntityManagerFactory; 
import javax.persistence.Persistence; 

import com.fks.nclp.model.MstStateDtl; 

public class Test_1 { 

    public static void main(String a[]){ 
     EntityManagerFactory emf = Persistence.createEntityManagerFactory("NCLPEntity"); 
     EntityManager em = emf.createEntityManager(); 

     MstStateDtl state = new MstStateDtl(); 
     state.setStateId(1002); 
     state.setZoneId(new BigDecimal("1234")); 
     state.setDescription("testing");   

     em.persist(state); 
     em.close(); 
     emf.close(); 
    } 
}

Answer 1

begin에서 트랜잭션을 시작하고 끝에 트랜잭션을 커밋해야합니다.

public static void main(String args[]) 
    { 
     EntityManager em; 
     try 
     { 
      em = Persistence.createEntityManagerFactory(
      "NCLPEntity").createEntityManager(); 

     em.getTransaction().begin(); 


     MstStateDtl state = new MstStateDtl(); 
     state.setStateId(1002); 
     state.setZoneId(new BigDecimal("1234")); 
     state.setDescription("testing"); 
     em.persist(state); 

     em.getTransaction().commit(); 

     } 
     finally 
     { 
     if (em != null) 
      em.close(); 
     } 
    } 

Answer 2

절대 EntityManager를 플러시하지 마십시오. 또한 어떤 종류의 거래가 유효하지 않습니다.

EntityManager em = emf.createEntityManager(); 
em.getTransaction().begin(); 

MstStateDtl state = new MstStateDtl(); 
state.setStateId(1002); 
state.setZoneId(new BigDecimal("1234")); 
state.setDescription("testing");   
em.persist(state); 
em.getTransaction().commit(); // performs an implicit flush 

em.close();
