我们有这个JPA / Spring设置，我们已经查看了许多关于同一错误的其他线程。我们似乎遵循了正确的方法。但是当我们在WebSphere中测试它时，我们会看到可怕的
javax.persistence.TransactionRequiredException: no transaction is in progress
我们知道我们可以在Spring事务中混合使用JPA和JDBCTemplate查询。但是我们需要一个Spring / JPA专家来查看我们的配置。

@PersistenceContext(unitName="pu1")
private EntityManager entityManager;
@Transactional("jpaTransactionManager")
public DeviceVO updatedDevStatus( Test test) {
entityManager.persist(test)
entityManager.flush();
}
