我的要求是从web应用程序接收消息json对象并将其（Json对象）路由到另一个Web应用程序，我正在使用camel用于此目的，这应该是一个相当简单的过程现在给我一个不眠之夜，我的骆驼路线如下：
<camel:route>
<camel:from uri="cxfrs://bean://lmrServer" />
<camel:to uri="log:output?showAll=true"/>
<setHeader headerName="CamelHttpMethod">
<constant>POST</constant>
</setHeader>
<camel:to uri="cxfrs:http://localhost:8080/RESTfulExample/rest/message"/>
现在下面是我的错误堆栈，在那里我可以看到邮件正文中的json对象，有些请让我知道我错在哪里，这会有很大帮助。谢谢提前..

我在骆驼中所做的更改 - 上下文
<dataFormats>
<json library="Jackson" unmarshalTypeName="org.payment.camel.example.MemberApplication" id="jack"/>
</dataFormats>
MemberApplication只是一个实现Serializable的pojo类。可以指出我错在哪里。
答案 0 :(得分：0)
交易所的正文包含一个对象
BodyType:org.apache.cxf.message.MessageContentsList, Body:[MemberApplication [name=xyz, organization=avc, nic=xyz, employeeId=5920]]
不应该在发送到
之前转换为json<camel:to uri="cxfrs:http://localhost:8080/RESTfulExample/rest/message"/>
答案 1 :(得分：0)
如果你想发送JSON，你必须先编辑你的对象。
你可以这样做：
<dataFormats>
<!-- here we define a Json data format with the id jack and that it should use the TestPojo as the class type when
doing unmarshal. The unmarshalTypeName is optional, if not provided Camel will use a Map as the type -->
<json id="jack" library="Jackson" unmarshalTypeName="org.apache.camel.component.jackson.TestPojo"/>
</dataFormats>
<camel:route>
<camel:from uri="cxfrs://bean://lmrServer" />
<camel:to uri="log:output?showAll=true"/>
<setHeader headerName="CamelHttpMethod">
<constant>POST</constant>
</setHeader>
<camel:marshal ref="jack"/>
<camel:to uri="cxfrs:http://localhost:8080/RESTfulExample/rest/message"/>
</camel:route>
有关详细信息，请参阅文档：camel-json doc。
