Я получаю исключение при создании простой веб-службы CXF с OSGI и Karaf.OSGI: исключение CXF с Karaf JAX-RS: для ресурса не найдены методы ресурсов
Был бы очень признателен за любые комментарии/предложения по исправлению.
Вот описание моего проекта и шаги, которые я последовал:
- Скачано Апач Karaf-4.0.7
- запустить «MVN чистую установку» в командной строке с пути моего проекта
Started Karaf консоль и выполните следующие команды
feature:repo-add cxf 3.1.8 feature:install cxf/3.1.8
Интерфейс:
public interface MyRestService {
String pingMe(String echo);
}
Реализация:
@Path("/")
public class MyRestServiceImpl implements MyRestService {
@GET
@Path("/{echo}")
@Produces(MediaType.APPLICATION_XML)
public String pingMe(@PathParam("echo") String echo) {
return "Knock Knock: " + echo + " !!";
}
}

Вы можете попробовать не для использования интерфейса, просто сделайте реализацию REST и аннотацию в классе 'MyRestServiceImpl'; У нас были некоторые проблемы с interfcaes в прошлом, и теперь вся наша служба REST определена только в классах. –
