我看到了很多问题，但他们所有的解决方案仍然不清楚。这是我设置的Spring Context文件

所有数据源和其他连接bean都已就位并正常工作。

我的DAO代码如下包com.my. dom.道；

@Component
public class MyDAOImpl implements MyDAO {

@PersistenceContext(unitName="PersistenceUnit1")
EntityManager entityManager; // this is IAR EntityManager.

@Override
@Transactional
public boolean saveMyGroups(
        List<MyGroups> theGroups) {

    logger.info("Entering method -  saveFuturetheGroups ");
    //entityManager.getTransaction().begin();
    for(MyGroups pg : theGroups){
        MyGroups attachedENtity = entityManager.merge(pg);
        entityManager.persist(pg);
    }
    //entityManager.getTransaction().commit();
    entityManager.flush();
    logger.info("Exiting method -  saveFuturetheGroups ");
    //List<MyGroups> savedEntities = futureProcGrpRepository.save(theGroups);
    return true;
}

}

正如Spring JPA@Transactional未提交中建议的那样，我在类路径中包含了所有cglib和aopalliance1.0. jars

我的代码仍然没有将更改提交给DB。任何帮助指针都会很有帮助。

代码显示选择和插入sql语句，没有异常抛出，但代码没有提交。@Transactional注释中是否有任何问题？

这里可以定义多个实体管理器吗？

好的，我发现如果我使用@Transactional（传播=传播。REQUIRES_NEW）

在我的方法之上，它提交了更改！！但是根据我的理解，传播的默认值是“必需的”，任何方式都会开始新的传输，并且应该在结束时提交？任何指针我现在真的很困惑！！

谢谢HK

只是一个注意事项，我正在从一个Junit测试用例中运行这个，有没有可能它正在明确地回滚更改？我在日志中看到了类似的内容

INFO : org.springframework.test.context.transaction.TransactionalTestExecutionListener - Rolled back transaction after test execution for test context [[TestContext@a5503a testClass = ProcessingGroupsTestCase, testInstance = null(com.wellmanage.dos.processingGroups.ProcessingGroupsTestCase), testMethod = testSave@ProcessingGroupsTestCase, testException = [null], mergedContextConfiguration = [MergedContextConfiguration@1363f5a testClass = ProcessingGroupsTestCase, locations = '{classpath:applicationContext.xml}', classes = '{}', activeProfiles = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader']]]

谢谢HK
