Question

我有一条简单的路线，如下所示：

Debug 'py.test in...'

cxf配置也非常简单：

<route handleFault="true" streamCache="true" id="routeA">
    <from uri="cxfrs://bean://simpleCxf" />
    <log message="The message body contains ${body}"/>
    <to uri="direct-vm:RouteB" />
</route>

<route handleFault="true" streamCache="true" id="routeB">
    <from uri="direct-vm:RouteB" />
    <bean ref="requestValidator" method="validateRequest" />
    <log message="The input message ${body}" />
    <bean ref="dbClient" method="queryDatabase" />
</route>

这条简单的路线因以下异常而失败

<cxf:rsServer id="simpleCxf" address="/test"
    loggingFeatureEnabled="true"
    serviceClass="com.gogol.test.TestResource">
</cxf:rsServer>

这是消息历史记录，表明它在No type converter available to convert from type: org.apache.cxf.message.MessageContentsList to the required type: org.apache.camel.Exchange with value [com.gogol.test.resource.SimpleObject@773736ca]

点失败

<bean ref="requestValidator" method="validateRequest" />

我认为问题在于Camel正在尝试将cxf生成的主体转换为Exchange对象。因为requestValidator类有一个签名为：

的方法

Message History
---------------------------------------------------------------------------------------------------------------------------------------
RouteId ProcessorId                   Processor                      Elapsed (ms)
[routeA] [routeA] [direct-vm://routeA                                ] [6]
[routeB] [log12 ] [log                                               ] [2]
[routeB] [to9   ] [direct-vm:routeA                                  ] [4]
[routeA] [bean26] [bean[ref:requestValidator method: validateRequest]] [2]

但理想情况下，cxf生成的消息应设置为Exchange内部的主体。我是否正确，如果没有，那可能是上述例外的原因？

编辑：

我使用的是CXF 3.0.4版本.redhat-621084 和CAMEL版本2.15.1.redhat-621084

public void validateRequest(Exchange exchange) thows SomeException.

我对camel xml dsl没有肯定如何正确格式化，但你总是可以明确告诉camel进行类型转换。您可以使用convertBodyTo调用来强制进行类型转换来测试您的理论。

from("myEndpoint")
    .log("This is my previous object")
    .convertBodyTo(TestResource.class)
    .log("This is my object after a camel type conversion");

Camel bean绑定尝试将主体转换为Exchange
