Question

请考虑以下代码：

class ClassOne {
      @Autowired
      ClassTwo classTwo;

      public void mainMethod() {
          Query query = em.createNativeQuery(...);
          classTwo.runTransaction(query);
     }
}

@Component
class ClassTwo {
    @Transactional
    public void runTransaction(Query) {
        System.err.println(TransactionSynchronizationManager.isActualTransactionActive());
        query.executeUpdate();
    }
}

运行mainMethod时，我遇到以下异常：

我觉得奇怪的是，即使您可以在堆栈跟踪中清楚地看到它通过TransactionInterceptor，它也会记录丢失的事务。

此外isActualTransactionAlive返回true。

您需要在事务上下文中获取Query对象。目前，它的外部交易背景。它会解决你的问题。

@Transactional for Native查询不会有任何问题
