JAX-RS Overwrite method with same path

Currently I have a generic rest service, which receives all the calls and processes them according to the type of operation.

Some of the calls would be:

• / user / 1 / v3 / people
• / user / 1 / v3 / machinery

Then depending on whether they are post or get or even if they have a specific suffix, a list, insertion, search with filters, modification or elimination is called.

The thing is that you want for a specific operation, when you pass a POST without any suffix (in the superclass it would be an insert), you do a search with filters (because in the superclass would be with the suffix "/ search")

@Path("/user/{userId}{a:\/v3\/|\/}{operation}")
public class Service {

 @POST
 @Consumes(MediaType.APPLICATION_JSON)
 @Produces(MediaType.APPLICATION_JSON)
 public Response insert(@Context final HttpHeaders httpHeaders,         
 @PathParam(USER_ID) final Integer userId,
        @PathParam(OPERATION_LABEL) final String oper, final String record) {
     //......
 }

 @POST
 @Path("/search")
 @Consumes(MediaType.APPLICATION_JSON)
 @Produces(MediaType.APPLICATION_JSON)
 public Response search(@Context final UriInfo uriInfo, @Context final HttpHeaders httpHeaders,
        @PathParam(USER_ID) final Integer userId, @PathParam(OPERATION_LABEL) final String oper,
        final String record) {

     //...........
  }
}

I have created a new class that has first specified the type of operation ("treatments") and then I want to overwrite the insert class, so that instead of doing an insert, I do a search.

@Path("/user/{userId}{a:\/v3\/|\/}tratamientos")
public class TratamientosService extends Service {

 @POST
 @Consumes(MediaType.APPLICATION_JSON)
 @Produces(MediaType.APPLICATION_JSON)
 @Override
 protected Response insert(final HttpHeaders httpHeaders, final Integer userId, final String oper, final String record) {
     //..............
 }
}

But you are giving me an error that does not overwrite the method.

GRAVE: Servlet [appServlet] in web application [/vnwebservicesnew] threw load() exception org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization. [[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method POST and input mime-types as defined by"@Consumes" and "@Produces" annotations at Java methods public javax.ws.rs.core.Response com.visualnacert.ws.version.base.services.TratamientosService.insert(javax.ws.rs.core.UriInfo,javax.ws.rs.core.HttpHeaders,java.lang.Integer,java.lang.String,java.lang.String) and public javax.ws.rs.core.Response com.visualnacert.ws.version.base.services.Service.insert(javax.ws.rs.core.HttpHeaders,java.lang.Integer,java.lang.String,java.lang.String) at matching regular expression /user/([^/]+)(\/v3\/|\/)tratamientos. These two methods produces and consumes exactly the same mime-types and therefore their invocation as a resource methods will always fail.; source='org.glassfish.jersey.server.model.RuntimeResource@18a82922']

Alternative path

I have also tried that the logic within the methods is in another protected method and in TratamientosService overwrite this protected method, but even though I do not skip error, when making the call, it does not go through the overwritten class.

Would there be any way that @Path("/user/{userId}{a:\/v3\/|\/}tratamientos") have higher priority than @Path("/user/{userId}{a:\/v3\/|\/}{operation}")
