我已经在spring + cxf：rsServer的帮助下实现了Restful Web服务。
<cxf:rsServer id="cxfContainer" address="/">
<cxf:serviceBeans>
<ref bean="restService"/>
</cxf:serviceBeans>
<cxf:extensionMappings>
<entry key="json" value="application/json" /> <!-- use .json to get data in JSON format -->
<entry key="xml" value="application/xml" /> <!-- use .xml to get data in XML format -->
</cxf:extensionMappings>
<cxf:providers>
<ref bean="jsonProvider" />
<ref bean="jaxbXmlProvider" />
</cxf:providers>
</cxf:rsServer>
现在我想将webservice上的xml / json输入路由到activemq。
所以我像添加了camelContext
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring" trace="true">
<route>
<from uri="cxfrs:bean:cxfContainer"/>
<choice>
<when>
<camel:xpath>/PlayerType/playerId= '007'</camel:xpath>
<inOnly uri="activemq:queue:RESTFULL.queue"/>
</when>
<otherwise>
<inOnly uri="activemq:queue:DefaultQueue"/>
</otherwise>
</choice>
</route>
</camelContext>
XML输入文件
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<PlayerType xmlns="http://benchresources.in/cdm/Player">
<playerId>007</playerId>
<name>abcd</name>
<age>30</age>
<matches>70</matches>
</PlayerType>
它引发以下错误。

最佳答案
在处理Camel的CXF端点时，我已经多次遇到此问题。本质上，当您从cxfrs bean获得响应时，cxf响应将封装在MessageContentsList（本质上是一个arraylist）中。之所以出错，是因为您试图将MessageContentsList对象放入org.w3c.dom.Document中，从而引发此错误。
您可以通过在cxfrs bean之后添加一个处理器来解决此问题，该处理器将响应从MessageContentsList中拉出并将其设置为消息的主体。像这样：
process(Exchange e){
MessageContentsList list = (MyObject) e.getIn().getBody();
MyObject obj = list.get(0);
e.getIn().setBody(obj);
}
