java - Spring 是否真的用 REQUIRES_NEW 启动了一个新事务？

Question

我的 spring (4.1.1) 应用程序部署在 JBoss-6.10-final 实例上，因此它使用基于容器的事务管理器和数据源。对于消息传递，我使用 TIBCO EMS 8.1 和 XA 队列连接工厂设置。 Java 版本为 1.8.0_20。所有这些都在我的 Ubuntu 14.04 笔记本电脑上运行。

我需要通过 JMS 发送请求，然后等待回复。我正在调用的 bean 将事务传播设置为 Propagation.REQUIRED，因此我需要在新事务中发送请求，然后等待回复。这意味着请求是在一个单独的 bean 中发送的，事务传播设置为 Propagation.REQUIRES_NEW。
它有效，但我收到了来自 JBoss 的令人担忧的警告:

...在 EMS 方面，我看到一些 XA 错误:

johan@my_machine:~/opt/jboss-6.1.0.Final/bin$ 2014-10-02 10:43:15.801 ERROR: Transaction for non-existent consumer: 15 connID=16 sessID=20 {formatID=131076 gtrid_length=29 bqual_length=28 data=%00%00%00%00%00%00%00%00%00%00%FF%FF%7F%00%01%01%00%00%12jT-%0D*%00%00%00%AF1%00%00%00%00%00%00%00%00%00%00%FF%FF%7F%00%01%01%00%00%12jT-%0D*%00%00%00%B1} 2014-10-02 10:43:15.832 ERROR: Error processing xa end - transaction marked ROLLBACKONLY, Exception. connID=16 sessID=20 {formatID=131076 gtrid_length=29 bqual_length=28 data=%00%00%00%00%00%00%00%00%00%00%FF%FF%7F%00%01%01%00%00%12jT-%0D*%00%00%00%AF1%00%00%00%00%00%00%00%00%00%00%FF%FF%7F%00%01%01%00%00%12jT-%0D*%00%00%00%B1}

查看堆栈跟踪后，我打开了 Spring 的 AbstractPlatformTransactionManager 的源代码并遇到了以下用于处理 REQUIRES_NEW 的代码(从第 415 行开始):

if (definition.getPropagationBehavior() == TransactionDefinition.PROPAGATION_REQUIRES_NEW) {
    if (debugEnabled) {
        logger.debug("Suspending current transaction, creating new transaction with name [" +
                definition.getName() + "]");
    }
    SuspendedResourcesHolder suspendedResources = suspend(transaction);
    try {
        boolean newSynchronization = (getTransactionSynchronization() != SYNCHRONIZATION_NEVER);
        DefaultTransactionStatus status = newTransactionStatus(
                definition, transaction, true, newSynchronization, debugEnabled, suspendedResources);
        doBegin(transaction, definition);
        prepareSynchronization(status, definition);
        return status;
    }
    catch (RuntimeException beginEx) {
        resumeAfterBeginException(transaction, suspendedResources, beginEx);
        throw beginEx;
    }
    catch (Error beginErr) {
        resumeAfterBeginException(transaction, suspendedResources, beginErr);
        throw beginErr;
    }
}

我的问题是:新交易从哪里开始？

从表面上看，似乎正在使用现有事务而不是正在启动新事务 - 看看“事务”是如何传递给 doBegin(...) 的。我也查看了 doBegin，没有迹象表明正在请求或创建新事务。这个 View 似乎得到了我从 JBoss 得到的堆栈跟踪和警告的支持......

Answer 1

很高兴看到我不是一个人被困在这个没有光的洞里......

据我了解，此警告的深层原因描述here (线程结束)

when the outer transaction is suspended and the new inner transaction started, the managed connection that Jboss connection pool retrieves for the inner transaction is the same as that of the outer transaction, which is causing the IllegalStateException to get thrown!

并且是由于 jboss JCA 契约(Contract)实现的特定行为 ( Lazy JCA enlistment )。

A defect has been opened on spring side ，标记为“无法修复”，但它们提供了一种解决方法配置:

The typical solution is to use Spring's TransactionAwareDataSourceProxy and switch the "reobtainTransactionalConnections" flag to "true" there
