Question

我想通过拦截使用InterceptFrom功能将缓存方面应用于Apache Camel路由路线中的每一个进入的交换。

我能够从单独的xml文件中成功加载RestDefinitions和RouteDefinitions。

以类似的方式，我想从单独的XML文件加载Intercept定义。

我目前在我的xml（Intercept.xml）文件中有以下内容，我用它来加载InterceptFrom定义，如下所示。我现在只记录它们。我将添加逻辑来检查最终的缓存命中/未命中。

 <interceptFrom>
        <log message="Intercepted Route" />
  </interceptFrom>

我正在使用以下方法加载它们，

List<InterceptFromDefinition> intDefns=getInterceptDefinitions("Intercept.xml");

我也将它们设置为路线。

routes.setInterceptFroms(intDefns);

我收到如下错误，

可能我需要使用类似于我包装Rest和RouteDefinitions的方式来包装interceptFrom。但是，不知道如何。我不确定我是否以正确的方式这样做。能以某种方式帮助我。

另外，我看到有一个可以设置为camelcontext的InterceptStrategy。

有没有办法可以通过应用缓存问题而不是InterceptFrom来使用它来执行AOP，例如处理我的路由。

另外，我的Camel应用程序基于Spring Boot，因此Spring Boot中有任何功能可以拦截路由调用。

我添加了我创建的示例项目，以使用XML文件在此repo中加载我的路由和apiroutes。同样，我想要使用拦截器来应用缓存的交叉问题，这样它们就不会与路由逻辑混合。我正在寻找一种方法来使用interceptFrom camel功能，这样我就可以拦截每条消息到路由并相应地处理它们。我不知道如何加载拦截器或如何将它们与路径链接。

由于名称空间错误，我目前已删除了为加载拦截器而添加的代码。有一次，我得到了解决方案的正确方法，我将相应地添加相同的方法。

你能提供完整的Intercept.xml吗？似乎您的Intercept.xml xml文件具有错误的命名空间，就像

一样

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <!-- intercept incoming messages and route them to the mock:middle1 endpoint
         before we proceed and continue routing from the point of interceptions, that
         is mock:end will be the next target -->
    <interceptFrom>
        <to uri="mock:middle1"/>
    </interceptFrom>

    <!-- here we have a very simple route -->
    <route>
        <from uri="direct:start"/>
        <to uri="mock:end"/>
    </route>
</camelContext>

使用InterceptFrom将缓存方面应用于Camel路由
