Question

我是Stack Overflow和Apache Camel路由的新手，我遇到了一些麻烦。我创建了一个非常简单的SOAP Web服务，它接受包含一些随机文本的XML请求，然后在响应中返回相同的字符串。

使用Camel我能够将请求发送到Web服务并获得响应（如果我使用日志组件来捕获请求/响应。

理想情况下，我想将XML消息（message1.xml，message2.xml，message3.xml）发送到Web服务，然后处理它们并将响应存储在文件中：src / data / responses /（message1.xml， message2.xml，message3.xml）等。我认为这可能就像在我的路线中添加一个额外的步骤一样简单（见下文）。

<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="file:src/data?noop=true" />
<log loggingLevel="INFO" message="${body}"/>
<to uri="cxf://http://localhost:8181/cxf/webservice?wsdlURL=src/main/resources/META-INF/webservice.wsdl&amp;serviceName={http://carose.com/}EchoServiceImplService&amp;portName={http://carose.com/}EchoServiceImplPort&amp;dataFormat=MESSAGE"/>
<log loggingLevel="INFO" message="${body}"/>
<to uri="file:src/data/responses" />
</route>
</camelContext>

但是，当我使用mvn camel:run运行路由时，它会在/ responses /文件夹中为每条消息创建一个空白XML文件。执行路径时会显示以下错误消息：

我假设它可能无法检索响应并将其存储在文件中，或者可能有一些东西可以指向我的方向？

感谢您的帮助！

Answer 1

我不确定message2.xml是否调用单向服务。你能仔细检查你的src / data目录中的message2.xml吗？如果是单向消息或无效的soap请求，您可能无法获得所需的正确输入流。

Answer 2

使用Camel v2.12.2，我没有得到异常，但在记录正文内容时该文件为空。这是因为流只能读取一次，请参阅here。因此，在使用CXF Web服务后删除日志：

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route>
        <from uri="file:src/data?noop=true" />
        <log loggingLevel="INFO" message="${body}"/>
        <to uri="cxf://http://localhost:8181/cxf/webservice?wsdlURL=src/main/resources/META-INF/webservice.wsdl&amp;serviceName={http://carose.com/}EchoServiceImplService&amp;portName={http://carose.com/}EchoServiceImplPort&amp;dataFormat=MESSAGE"/>
        <!-- do not log the body or the file written will be empty
        <log loggingLevel="INFO" message="${body}"/>
        -->
        <to uri="file:src/data/responses?fileName=output.txt" />
    </route>
</camelContext>

除此之外，我添加了fileName选项以获得一个漂亮的文件名。

Answer 3

我想我已经成功解决了这个问题。

我认为这可能是因为路由期间没有缓存或存储任何响应，导致它创建空白文件（message1.xml，message2.xml和message3.xml）。我发现你可以设置一个流缓存设置，所以我打开它，它现在正在创建所有三个文件，其中包含正确的XML响应。请参阅下面的路由XML：

<camelContext xmlns="http://camel.apache.org/schema/spring">
<route streamCache="true">
    <from uri="file:src/data?noop=true" />
    <log loggingLevel="INFO" message="${body}"/>
    <to uri="cxf://http://localhost:8181/cxf/webservice?wsdlURL=src/main/resources/META-INF/webservice.wsdl&amp;serviceName={http://carose.com/}EchoServiceImplService&amp;portName={http://carose.com/}EchoServiceImplPort&amp;dataFormat=MESSAGE"/>
    <log loggingLevel="INFO" message="${body}"/>
    <to uri="file:src/data/responses" />
</route>
