TransactionRequiredException Executing an update/delete query

Hi I am using hibernate JPA with spring and mongodb and i am running my application on Glassfish-4.0.

My service class is :

@Component
public class T

I am not sure if this will help your situation (that is if it stills exists), however, after scouring the web for a similar issue.

I was creating a native query from a persistence EntityManager to perform an update.

Query query = entityManager.createNativeQuery(queryString);

I was receiving the following error:

caused by: javax.persistence.TransactionRequiredException: Executing an update/delete query

Many solutions suggest adding @Transactional to your method. Just doing this did not change the error.

Some solutions suggest asking the EntityManager for a EntityTransaction so that you can call begin and commit yourself. This throws another error:

caused by: java.lang.IllegalStateException: Not allowed to create transaction on shared EntityManager - use Spring transactions or EJB CMT instead

I then tried a method which most sites say is for use application managed entity managers and not container managed (which I believe Spring is) and that was joinTransaction().

Having @Transactional decorating the method and then calling joinTransaction() on EntityManager object just prior to calling query.executeUpdate() and my native query update worked.

I hope this helps someone else experiencing this issue.

Using @Modifying and @Transaction fixed me

1. @Modifying @Query(value="DELETE FROM lock WHERE user_id = ?1" ,nativeQuery=true) void deleteByUserId(Long userId);

2. @Service @Transactional

Answer 3

If the previous answers fail, make sure you use @Service stereotype for the class where you call the update method on your repository. I originally used @Component instead and it was not working, the simple change to @Service made it work.

You need not to worry about begin and end transaction. You have already apply @Transactional annotation, which internally open transaction when your method starts and ends when your method ends. So only required this is to persist your object in database.

 @Transactional(readOnly = false, isolation = Isolation.DEFAULT, propagation = Propagation.REQUIRED, rollbackFor = {Exception.class})

         public String persist(Details details){
             details.getUsername();
             details.getPassword();
             Query query = em.createNativeQuery("db.details.find(username= "+details.getUsername()+"& password= "+details.getPassword());

             em.persist(details);
             System.out.println("Sucessful!");
            return "persist";        
     }

EDIT : The problem seems to be with your configuration file. If you are using JPA then your configuration file should have below configuration

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"
    p:entityManagerFactory-ref="entityManagerFactory" />
<bean id="jpaAdapter"
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"
    p:database="ORACLE" p:showSql="true" />
<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    p:persistenceUnitName="YourProjectPU"
    p:persistenceXmlLocation="classpath*:persistence.xml"
    p:dataSource-ref="dataSource" p:jpaVendorAdapter-ref="jpaAdapter">
    <property name="loadTimeWeaver">
        <bean
            class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
    </property>
    <property name="persistenceProvider" ref="interceptorPersistenceProvider" />

</bean>

Using @PersistenceContext with @Modifying as below fixes error while using createNativeQuery

    import org.springframework.data.jpa.repository.Modifying;
    import org.springframework.transaction.annotation.Transactional;

    import javax.persistence.EntityManager;
    import javax.persistence.PersistenceContext;
    import javax.persistence.Query;

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    @Transactional
    @Modifying
    public <S extends T> S save(S entity) {
         Query q = entityManager.createNativeQuery(...);
         q.setParameter...
         q.executeUpdate();
         return entity;
    }

I received this exception when trying to run a bulk UPDATE query in a non-JTA (i.e. resource-local) entity manager in Java SE. I had simply forgotten to wrap my JPQL code in

em.getTransaction().begin();

and

em.getTransaction().commit();
