Can't we have multiple @Search() methods in a class ?

I have a situation to create two @Search() methods in a class.

here is the illustration.

@Path("/Resource")

@Produces({ MediaType.APPLICATION_JSON, Constants.CT_FHIR_JSON, Constants.CT_FHIR_XML })

public class ReportResourceProvider

{

....

@Search()

public List<Resource> getReportByPatient(@RequiredParam(name = Resource.SP_PATIENT) ReferenceParam patient,

@RequiredParam(name = Resource.SP_VALUE_QUANTITY) String count,

@RequiredParam(name = Resource.SP_IDENTIFIER) String startVal)

{...

}

@Search()

public Resource searchRporteByEncounter(@RequiredParam(name = Resource.SP_ENCOUNTER ) ReferenceParam encounter

{

...

}

When I try to implement the same, I' getting the following exception

java.lang.IllegalArgumentException: Multiple Search Method Bindings Found

FWIW this is definitely possible in the regular (non JAX-RS) server. It's possible that there is a limitation in the JAX-RS module though..

I'm trying to do that in regular (non JAX-RS) server but I'm ended up with

java.lang.IllegalArgumentException: Multiple Search Method Bindings Found : public java.util.List com..........

at ca.uhn.fhir.jaxrs.server.util.JaxRsMethodBindings.addMethodBinding(JaxRsMethodBindings.java:89)

at ca.uhn.fhir.jaxrs.server.util.JaxRsMethodBindings.<init>(JaxRsMethodBindings.java:61)

at ca.uhn.fhir.jaxrs.server.util.JaxRsMethodBindings.getMethodBindings(JaxRsMethodBindings.java:138).....

That is definitely the JAX-RS server you're using- you can see "JaxRsMethodBindings" right in the stack trace.

The following sample project might be helpful in terms of getting started with the non-jaxrs server:

I'm having the same problem and checked the code where the error was thrown. It seems like it's not possible to have more than one method with @Search annotation, unless it's a compartment? Without compartment, the key is always the default key. Is the implementation guide wrong?

/**
* Get the key for the baseMethodBinding. This is:
* <ul>
* <li>the compartName for SearchMethodBindings
* <li>the methodName for OperationMethodBindings
* <li> {@link #DEFAULT_METHOD_KEY} for all other MethodBindings
* </ul>
* @param theBinding the methodbinding
* @return the key for the methodbinding.
*/
private String getBindingKey(final BaseMethodBinding theBinding) {
if (theBinding instanceof OperationMethodBinding) {
return ((OperationMethodBinding) theBinding).getName();
} else if (theBinding instanceof SearchMethodBinding) {
Search search = theBinding.getMethod().getAnnotation(Search.class);
return search.compartmentName();
} else {
return DEFAULT_METHOD_KEY;
}
}

Ok, just additional information, this is for the class extending the AbstractJaxRsResourceProvider
