Question

我正在使用JmsOutboundGateway和MessageChannelPartitionHandler进行分区批处理作业。我希望能够在句柄方法

中中断此代码

Message<Collection<StepExecution>> message = messagingGateway.receive(replyChannel);

从另一个线程我试图在这个线程上调用interrupt（）。添加此功能的最佳方法是什么？

澄清：

中断确实有效。但是，确实接收响应的每个分区的线程都有一个堆栈跟踪（如下所示）。这些线程仍然被阻塞，从而将它们从该线程池中拉出来，并且它们不可用于后续的分区作业。

如何访问这些线程以进行中断？

Answer 1

中断线程会起作用;但是，中断被捕获（并且QueueChannel中的中断位重新设置）。

在此之后，收到的消息为空，因此分区处理程序将抛出MessageTimeoutException。

目前无法确定超时是由于实际超时还是中断。

中断MessageChannelPartitionHandler
