SessionFactory Hibernate doesn't commit Oracle database

Question

I work with Spring MVC 3.2.6,Hibernate 4, Oracle and weblogic 10.3.6

I want to commit in Oracle database a entity using Hibernate and JPA. In server console I don't see errors. But when I check the Oracle table, new records aren't recorded.

This is my JPA entity

package eusurvey.modelA.daos;

import java.io.Serializable;
import javax.persistence.*;


/**
 * The persistent class for the PREFERENCIAS database table.
 * 
 */
@Entity
@Table(name="PREFERENCIAS")
public class Preferencia implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="PREFERENCIAS_ID")
    private long preferenciasId;

    private String nombre;

    private String valor;

    public Preferencia() {
    }

    public long getPreferenciasId() {
        return this.preferenciasId;
    }

    public void setPreferenciasId(long preferenciasId) {
        this.preferenciasId = preferenciasId;
    }

    public String getNombre() {
        return this.nombre;
    }

    public void setNombre(String nombre) {
        this.nombre = nombre;
    }

    public String getValor() {
        return this.valor;
    }

    public void setValor(String valor) {
        this.valor = valor;
    }

}

Service class AdministrationService.java.I use the method createPreferencia .

package eusurvey.services;

import java.util.ArrayList;
import java.util.List;

import javax.annotation.Resource;



import org.hibernate.Query;
import org.hibernate.SQLQuery;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.apache.log4j.Logger;

import eusurvey.modelA.daos.EncuestaSem;
import eusurvey.modelA.daos.Encuestado;
import eusurvey.modelA.daos.Preferencia;
import eusurvey.tools.ConversionTools;


@Service("administrationService")
public class AdministrationService {
    private static final Logger logger = Logger.getLogger(AdministrationService.class);

    @Resource(name="sessionFactory")
    private SessionFactory sessionFactory;



    @Transactional
    public void createEncuestado(Encuestado encuestado) throws Exception {
        Session session = sessionFactory.getCurrentSession();



        session.save(encuestado);
    }   

    @Transactional(readOnly = false)
    public void createEncuesta(EncuestaSem encuesta) throws Exception {
        Session session = sessionFactory.getCurrentSession();


        logger.info("fecha inicio "+encuesta.getFechaInicio());
        session.save(encuesta);
        logger.info("Grabada encuesta");
    }   

    @Transactional(readOnly = false)
    public void createPreferencia(Preferencia preferencia) throws Exception {
        Session session = sessionFactory.getCurrentSession();



        session.save(preferencia);
        logger.info("Grabada prefencia");
    }   

}

Java where I call to createPreferencia method is

administrationService.createPreferencia(preferencia);

Console server messages are

How can I check SQL sentence?

Answer 1

If you use <tx:annotation-driven/> You must define transactionManager like this:

<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="mySessionFactory" />
</bean>

The id must be txManager, otherwise you should define the special id for the transactionManager like this.

<tx:annotation-driven transaction-manager="myTxManager" />

And you should change you code like this @Transactional(propagation = Propagation.REQUIRED,readOnly = false). If you didn't define the Propagation, the default value is SUPPORTS, if there is not a transaction outside, the code would execute in transaction. So no transaction begin and no transaction commit. All by all, just Use @Transactional(propagation = Propagation.REQUIRED,readOnly = false)
