Apache的骆驼截取 - 捕获输出。 [英] Apache Camel Intercept - Capture Output.

问题描述

我在尝试使用Apache的骆驼拦截在spring.xml文件以捕获传入的请求和传出的响应，如：

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&amp;
            convertAttachments=true" />
        <camel:to
            uri="sonicesb://Process/rConnect?bindingStrategy=#ExposeBindingStrategy.Resource.rConnect.rconnect&amp;headerFilterStrategy=#ExposeHeaderFilterStrategy.Resource.rConnect.rconnect&amp;esbConfig=#ExposeEsbConfig.Resource.rConnect.rconnect" />
    </camel:route>
    <camel:route autoStartup="false">
        <camel:from
            uri="directsonicesb:Resource.rConnect.rconnect?bindingStrategy=#InvokeBindingStrategy.Resource.rConnect.rconnect&amp;headerFilterStrategy=#InvokeHeaderFilterStrategy.Resource.rConnect.rconnect&amp;uriTemplate=#URITemplate.Resource.rConnect.rconnect" />
        <camel:to uri="sonicesb://Process/rConnect" />
    </camel:route>
</camel:camelContext>

这个文章。

但CaptureProcessor仅在输入周期调用一次。

But the "CaptureProcessor" is only called once on the input cycle.

我怎样才能使它捕获输出呢？

How can I make it capture the Output as well?

推荐答案

按照骆驼DOC ，这是不可能的拦截：

什么情况是，交易所在每一个加工步骤之前截获的，这意味着它会在

What happens is that the Exchange is intercepted before each processing step, that means that it will be intercepted before

因此​​，这是不可能拦截每个步骤之后的处理的。然而，有一个开放的吉拉票这一要求： 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

另外，你可以使用 onCompletion 就是像一个可以为每个路由或全球整个骆驼上下文定义完成回调后：

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>

查看骆驼文档关于这种可能性的更多信息。

See the Camel docs for more information about this possibility.
