Apache Camel 拦截 - 捕获输出. [英] Apache Camel Intercept - Capture Output.
问题描述
我正在尝试在 spring.xml 文件中使用 Apache Camel Interceptor 来捕获传入请求和传出响应,如下所示:
I am attempting to use Apache Camel Interceptor in the spring.xml file to capture incoming requests and outgoing responses, like this:
<bean id="InterceptProcessor" class="CaptureProcessor"/>
<camel:camelContext id="camel">
<camel:jmxAgent id="agent" disabled="true" />
<camel:intercept>
<camel:process ref="InterceptProcessor"></camel:process>
</camel:intercept>
<camel:route id="Resource.rConnect.rconnect" autoStartup="false">
<camel:from
uri="cxfjetty:${Resource.rConnect.rconnect.baseUrl}?urlTemplateRef=#URLTemplateRef.Resource.rConnect.rconnect&
convertAttachments=true" />
<camel:to
uri="sonicesb://Process/rConnect?bindingStrategy=#ExposeBindingStrategy.Resource.rConnect.rconnect&headerFilterStrategy=#ExposeHeaderFilterStrategy.Resource.rConnect.rconnect&esbConfig=#ExposeEsbConfig.Resource.rConnect.rconnect" />
</camel:route>
<camel:route autoStartup="false">
<camel:from
uri="directsonicesb:Resource.rConnect.rconnect?bindingStrategy=#InvokeBindingStrategy.Resource.rConnect.rconnect&headerFilterStrategy=#InvokeHeaderFilterStrategy.Resource.rConnect.rconnect&uriTemplate=#URITemplate.Resource.rConnect.rconnect" />
<camel:to uri="sonicesb://Process/rConnect" />
</camel:route>
</camel:camelContext>
关注这篇文章.
但是CaptureProcessor"只在输入周期被调用一次.
But the "CaptureProcessor" is only called once on the input cycle.
如何让它也捕获输出?
推荐答案
根据Camel doc,这对于 intercept
是不可能的:
According to the Camel doc, this is not possible with intercept
:
发生的情况是Exchange在每个处理步骤之前被拦截,这意味着它会在之前被拦截
What happens is that the Exchange is intercepted before each processing step, that means that it will be intercepted before
因此,不可能在每个步骤之后拦截处理.但是,有一个针对此要求的开放式 Jira 票证:CAMEL-6901
Thus, it is not possible to intercept the processing after each step. However, there's an open Jira ticket for this requirement: CAMEL-6901
或者,您可以使用 onCompletion
,它类似于一个完成后的回调,可以为每条路由定义或为整个 Camel 上下文全局定义:
Alternatively, you may use onCompletion
that is like an after completion callback which can be defined for each route or globally for the whole Camel context:
<onCompletion>
<log message="${body}" />
</onCompletion>
有关这种可能性的更多信息,请参阅 Camel 文档.
See the Camel docs for more information about this possibility.
