The above should be:
@Consumes({"text/plain", "application/json"})

Marc's reply shows how you can get the selected media type and then
you can compare that media type.
Depending on what you are doing it might be easier to separate out
your methods:
@GET
@Consumes("text/plain")
@Path("{id}")
public String getText(...) {
}
@GET
@Consumes("application/json")
@Path("{id}")
public String getJson(...) {
}
It is possible to avoid duplication of @Path by using a sub-resource
locator. If you want to share state with the parent resource that
class can be a non-static public inner class, so one could do:
@Path("{id}")
public Inner getId(...) {
return new Inner();
}
public class Inner {
@GET
@Consumes("text/plain")
public String getText(...) {
}
@GET
@Consumes("application/json")
public String getJson(...) {
}
}
