如何从全局线路分接头获取频道信息 [英] How to get channel information from a global wire tap

问题描述

有没有办法使用全局线路分路并且仍然能够记录有关相关频道的标识信息?为了澄清让我们假设，我想使用 global wire tap 如下:

Is there a way to use a global wire tap and still be able to log the identification information about the associated channel? To clarify lets suppose, I want to use a global wire tap as follows:

...
<int:channel id="myChannel1" />
...
<int:channel id="myChannel2" />
...

<int:wire-tap pattern="*" order="2" channel="wireTapChannel" />

<int:logging-channel-adapter
   id="wireTapChannel"
   expression="'payload: ' + getPayload()"
   level="DEBUG"
   logger-name="WIRETAP" />

这会记录类似的内容

14:44:31,350 DEBUG WIRETAP:126 - payload: some payload1
14:44:31,350 DEBUG WIRETAP:126 - payload: some payload2

现在有没有办法放置一个表达式，以便查看日志我也可以识别相关的频道?我期待这样的事情:

Now is there a way to put an expression so that looking into the logs I can identify the associated channels as well? I am expecting something like this:

14:44:31,350 DEBUG WIRETAP:126 - channel: myChannel1, payload: some payload1
14:44:31,350 DEBUG WIRETAP:126 - channel: myChannel2, payload: some payload2

不确定一旦流到达wireTapChannel，这个信息是否已经丢失

Not sure whether this information is already lost once the flow reaches the wireTapChannel

推荐答案

您可以启用 消息历史记录，然后使用 Spel 打印所需的标题.

You could enable Message History and then use a Spel to print the desired headers.
