Question

我的轮询器从数据库中获取数据后，我正在调用外部服务。从该服务获得响应后，我想在一个单独的线程中调用另一个系统。意思是，在得到回复之后，我的轮询器应该再记录并发送。另外调用其他系统应该并行工作。

为此，我使用直接通道从DB接收数据。使用服务激活器向外部服务发送请求。响应被传递给执行者channel.can任何人请告诉我下面的配置是否适用于该场景？

为清楚起见，我正在共享poller.xml

Answer 1

没有;它不正确（几乎是正确的）。

<stream:stdout-channel-adapter id="executerchannel"/>

这会覆盖您的执行程序通道定义（没有channel属性的出站适配器会创建一个具有该ID的通道。）

您最终会得到一个简单的直接频道，其中包含2个订阅者（stdout和您的服务激活器） - 他们将获得备用消息。

我不确定你为什么要添加这个元素;将其删除或订阅其他频道。

如果你想要去两个地方;使用执行程序将频道更改为<publish-subscribe-channel/>。
