我正在尝试将来自cxf rest服务的rest请求路由到另一个。我看了http://camel.apache.org/cxfrs.html，这有助于理解部分过程。我在remoteService Invocation级别有一个classCastException。
我做错了什么？
<cxf:rsServer id="exposedService" address="/exposed/"
serviceClass="com.example.project.ExposedService" />
<!-- using different classes since we are not just proxying -->
<cxf:rsClient id="remoteService" address="http://remote.com/service"
serviceClass="com.example.project.RemoteService" />
<camel:camelContext xmlns="http://camel.apache.org/schema/spring">
<package>com.example.project</package>
</camel:camelContext>
@Path("/myservice")
public class ExposedService {
@POST
@Consumes("application/xml")
public void postResource(javax.xml.transform.Source resource) {
// source : not using jaxb just plain xml
// only serves to configure the endpoint (?)
}
}
public class RemoteService {
@POST
@Consumes("application/xml")
public void postResource(javax.xml.transform.Source resource) {
// source : not using jaxb just plain xml
// only serves to configure the endpoint (?)
}
}
public class MyRouteBuilder extends RouteBuilder {
public void configure() {
from("cxfrs://bean://exposedService")
.process(...) // a few System.out.println's
.to("cxfrs://bean://remoteService")
;
}
}
