Hi all,
I'm creating a RESTful web service, but I don't understand how to manage
multiple parameters in the exchange message. My idea is that if multiple
parameters are passed to the service, I can find some sort of hashmap, indexed
by parameter name, in the body of the message created by the REST endpoint, but
this doesn't happen.
Reading from the source code, method
org.apache.camel.component.cxf.jaxrs.DefaultCxfRsBinding.populateExchangeFromCxfRsRequest(...),
I see that a "Object[] paramArray" (that has only parameters values and not
names) is saved in the message body with "camelMessage.setBody(new
MessageContentsList(paramArray))".
Am I missing something or multiple parameters are really passed as *positional*
parameter of an Object[] array?
I'm using Camel 2.7.1 with the following definition (I've pasted only the
relevant portion)
@Provider
@Produces("application/json")
public class DocumentListRest {
@GET
@Path("/document/{userId}/{documentId}")
public Document getDocument(@PathParam("userId") long userId,
@PathParam("documentId") long documentId) {
return null; // Is it ok if I return null?
}
}
my Spring configuration is:
[...]
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-http.xml" />
<cxf:rsServer id="rsServer" address="/"
serviceClass="xxx.yyy.impl.DocumentListRest" />
<camelContext id="camel" trace="true"
xmlns="http://camel.apache.org/schema/spring";>
<route>
<from uri="cxfrs:bean:rsServer" />
<choice>
<when>
<simple>${in.header.operationName} == 'getDocument'</simple>
[...]
</route>
</camelContext>
Tracing gave me the follwing output:
(route1) from(cxfrs://bean:rsServer) --> choice <<< Pattern:InOut,
Headers:{CamelAcceptContentType=*/*, Content-Type=null, Accept=*/*,
CamelHttpUri=/server/document/23/234, CamelHttpMethod=GET,
connection=Keep-Alive, CamelCxfRsResponseClass=class xxx.yyy.bean.Document,
CamelCxfRsOperationResourceInfoStack=[org.apache.cxf.jaxrs.model.MethodInvocationInfo@3b48a8e6],

operationName=getDocument, CamelCxfRsResponseGenericType=class

Thanks,
