Question

我使用类似的基于文件的集成模式有 2 spring integration context 文件。两个扫描目录都在查找消息，如果自己部署则都可以工作。如果我将这两个模块包含在另一个弹簧上下文中，则它们会正常加载但是只有第二个正在运行，第一个正在运行： MessageDeliveryException：Dispatcher没有订阅者。我试图将它们组合成一个没有正增益的上下文文件。我们目前正在使用Spring Integration的2.1.3版和Spring Integration File的2.1版。非常感谢任何想法！

我在配置中看到了这个问题：

<int:service-activator id="batchJobLaunchService" ref="inPaymentService" input-channel="file-inpayment-channel"
    method="schedule" />

和

<int:service-activator id="batchJobLaunchService" ref="launchService" input-channel="scheduler-file-in-channel"
    method="schedule" />

他们假设是不同的服务，但同时使用相同的id - batchJobLaunchService。

Spring默认允许这样做，但只有具有相同id的最后一个bean定义才会获胜。这就是为什么<service-activator>的{{1}}没有被贬低的原因，因此launchService bean没有订阅EventDrivenConsumer。

小心并为所有豆类使用唯一ID。

在复制案例中投入预测并不容易，但如果您为scheduler-file-in-channel类别打开INFO，则会显示一个bean覆盖另一个bean的消息。
