Thanks for the example Christian. Obviously I didn't search the web well
enough :)
I tried to replicate your example and everything works as expected.
I have a question though: Assume rest interface is different than model
interface (but somewhat overlapping), or simply assume I don't want my
model to be "polluted" with JAXRS annotations.
I thought I could remove all the annotation within the service interface
and add the same annotations within the rest class. Something like:
interface:
public interface TaskService {
public Task getTask(String id);
public void addTask(Task task);
public void updateTask(Task task);
public void deleteTask(String id);
public Task[] getAll();
public default Collection<Task> getTasks() {
return Arrays.asList(this.getAll());
}
}
rest:
@Api
@Path("")
@Produces(MediaType.APPLICATION_XML) //if you want to generate json instead
@Component(
immediate = true,
name = "TaskService",
property = {
"service.exported.interfaces=*",
"service.exported.configs=org.apache.cxf.rs",
"org.apache.cxf.rs.address=/tasks2",
}
)
public class TaskRest implements TaskService {
//reference of another implementation of TaskService, inside osgi framework
@Reference
private TaskService taskService;
@GET
@Path("/{id}")
public Task getTask(@PathParam("id") String id) {
return this.taskService.getTask(id);
}
@PUT
public void addTask(Task task) {
this.taskService.addTask(task);
}
@Override
public void updateTask(Task task) {
this.addTask(task);
}
@DELETE
@Path("/{id}")
public void deleteTask(String id) {
this.taskService.deleteTask(id);
}
@GET
public Task[] getAll() {
return this.taskService.getAll();
}
}
However, rsa:endpoints does not detect the rest service when the rest
bundle starts.
Is this an expected behaviour (since I removed an interface with JAXRS
annotation)? Can I make this work?
I know the example I have provided does not make any sense (it's just a
semantic-less wrapper of an osgi service).
Thanks you very much!
