我需要用org.springframework.transaction.jta.JtaTransactionManager我的TransactionManager春天Service。但是，它不对JPA实体进行任何更改。我知道，如果我使用JpaTransactionManager它会起作用。但是，我需要JtaTransactionManager。因此，建议您不要使用JpaTransactionManager。我的spring班Service是：

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);
    }
}

我的Spring xml配置是：

如何在使用提交的JPA实体中进行更改JtaTransactionManager？
