我试图了解 HK2 Factory 在 Jersey 应用程序中的实现。

目标：如何实现单例工厂？

    // Below is the simple factory implementation

    public class MyFactory implements Factory<SomeObject> {

        private static final Logger logger = LoggerFactory.getLogger(MyFactory.class);
        private final CloseableService closeService;

        @Inject
        public MyFactory(CloseableService closeService) {
            this.closeService = closeService;
        }

        @Override
        public MyFactory provide() {
            logger.debug("provide object from MyFactory");
            SomeObject objectFromFactory = new SomeObject();
            this.closeService.add(() -> dispose(objectFromFactory));
            return objectFromFactory;
        }

        @Override
        public void dispose(SomeObject instance) {
            // destroy instance
             logger.debug("dispose object from MyFactory");
        }
    }

    // and binding
     bindFactory(MyFactory.class).to(SomeObject.class).in(Singelton.class);

     // …
