Java Apache Camel CXF端点空回复

java web-services apache-camel

Java Apache Camel CXF端点空回复,java,web-services,apache-camel,cxf,Java,Web Services,Apache Camel,Cxf,我遵循《骆驼行动手册》的第7章，实现了一个CXF路线 <cxf:cxfEndpoint id="orderEndpoint" address="http://localhost:9000/order/" serviceClass="test.order.OrderEndpoint" wsdlURL="wsdl/order.wsdl" /> <camelContext xmlns="http://camel.apache.org/sche

我遵循《骆驼行动手册》的第7章，实现了一个CXF路线

<cxf:cxfEndpoint 
    id="orderEndpoint" 
    address="http://localhost:9000/order/"
    serviceClass="test.order.OrderEndpoint" 
    wsdlURL="wsdl/order.wsdl" />


<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route>
        <!-- Expose route as web service endpoint -->
        <from uri="cxf:bean:orderEndpoint" />
        <to uri="log:orderEndpoint_MsgIn" />
        <to uri="seda:incomingOrders" />
        <transform>
            <constant>OK</constant>
        </transform>
        <to uri="log:orderEndpoint_MsgOut" />
    </route>

    <!-- test route -->
    <route>
        <from uri="seda:incomingOrders" />
        <to uri="mock:end" />
    </route>
</camelContext>
然而，我得到了

"Received reply from orderEndpoint = null"
在控制台日志中，我可以看到

"orderEndpoint_MsgOut           INFO  Exchange[ExchangePattern: InOut, BodyType: String, Body: OK]"
这意味着Web服务应该已经生成了回复消息“OK”，但我不确定为什么这个回复消息没有作为requestBody（）方法调用的返回值进行传递

我下载了Camel in Action第7章的示例代码并运行Junit测试用例，它能够按预期返回结果。。。我试图将路由定义和源代码与我的进行比较，但到目前为止没有发现任何差异

我想看看是否有人能提供一些线索

---编辑1---

我已更新路线定义，仅保留如下路线

    <route>
        <from uri="cxf:bean:orderEndpoint" />
        <transform>
            <constant>OK</constant>
        </transform>
        <to uri="seda:incomingOrders" />
    </route>
但是，它因超时异常而失败

您正在请求CXF端点的主体。如果查看管线，可以看到在“变换”标记中设置了主体的内容，该标记位于管线定义的后面。因此，由于
requestBody（）
，您没有获得OK是合乎逻辑的。这同样适用于您的seda端点。我敢打赌，
orderEndpoint\u MsgIn
的日志正文与OK不同

关于您在
orderEndpoint\u MsgOut
上的日志是否正确，这是因为您在转换步骤后记录了正文

要接收OK，您可以使用以下路线：

<route>
    <from uri="cxf:bean:orderEndpoint" />
    <transform>
        <constant>OK</constant>
    </transform>
    <wireTap uri="seda:incomingOrders" />
</route>
您应该在
requestBody（）
和
main.stop（）之间使用此代码


有关使用
wireTap
而不是
to
的说明，请参见此
您认为orderEndpoint\u MsgIn不同于“OK”是正确的--它记录了cxf MessageContesticsList对象，其中body等于传入参数“motor”之一，如下所示：orderEndpoint\u MsgIn信息交换[ExchangePattern:InOut，BodyType:org.apache.cxf.message.MessageContentsList，Body:motor]您能告诉我如何修改路由或主程序以获得“确定”吗回复字符串？不幸的是它仍然不起作用…我已经编辑了我的原始问题和最新的异常found@xlogger您可以在堆栈跟踪中看到exchange主体正常。您的问题似乎与此处相同，我进行了相应的编辑。感谢您的更新和参考链接。我现在可以使用了。我唯一的评论是y我们在ConsumerTemplate上的代码不起作用，因为main中没有createConsumerTemplate（）方法（我使用Camel 2.15.0进行测试）。我是通过从Camel上下文获取消费者模板来实现的（请参阅我编辑的代码）…希望您能在我将您的答案标记为已接受答案之前对消费者模板代码进行最后编辑。再次感谢您的支持help@xlogger它现在应该与您的代码片段一致。

    producer.requestBody("cxf:bean:orderEndpoint", params, String.class);
    ConsumerTemplate consumer = producer.getCamelContext().createConsumerTemplate();
    Exchange reply = consumer.receive("seda:incomingOrders");
    LOG.info("Received reply from seda:incomingOrders = " + reply);
