Ich muss @ verwendorg.springframework.transaction.jta.JtaTransactionManager wie meinTransactionManager im FrühlingService. Es werden jedoch keine Änderungen an JPA-Entitäten festgeschrieben. Ich weiß das, wenn ich @ benutJpaTransactionManager Es klappt. Aber ich braucheJtaTransactionManager. Also, bitte nicht empfehlen, @ zu verwendJpaTransactionManager. Mein FrühlingService Klasse ist:

package testspring.view;

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

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import testspring.model.Regions;


@Service
public class HelloBS {
    @PersistenceContext
    private EntityManager entityManager;

    public HelloBS() {
        super();
    }

    @Transactional()
    public void doSomething() {
        Regions region = new Regions();
        region.setRegionName("Antarctica");
        entityManager.persist(region);
    }
}

Und meine Spring xml Konfiguration ist:

Wie kann ich Änderungen an JPA-Entitäten vornehmen lassen, die mit @ festgeschrieben wurdeJtaTransactionManager?
