私は休止状態の世界が初めてで、デモサンプルを準備しています。entityManager.persist(entity) 関数で試しました。エラーはありませんが、エンティティは DB に永続化されていません。

これが私のpersistence.xmlファイルです...

そして、ここに私が永続化機能をテストしている場所からのスタブがあります...

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();
    }
}

これがコンソールアウトアウトです...

EntityManager をフラッシュすることはありません。また、有効なトランザクションもありません。

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();

最初にトランザクションを開始し、最後にトランザクションをコミットする必要があります。 

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();
      }
   }
