我使用javax.ws.rs注释在 OSGi 容器 (Karaf) 中发布了 REST 端点。HttpService 由 pax-web 创建，jax-rs 服务由com.eclipsesource.jaxrs/publisher.

为了使用这个发布者，伪造了一个非常可怕的功能（从互联网的某个地方复制）：

</feature>

它通常可以工作，但是当我尝试按照 wiki 中的描述注册事件侦听器时，从未调用过该侦听器。另一个问题是功能中以“幻数”作为起始级别的库数量，以及平台升级的潜在问题。

pax-web 是否具有发布 jax-rs 端点的机制，我可以使用它来代替伪造的功能？我需要激活什么才能发布我的端点？

CXF 是发布 REST 端点的一个选项。可以在https://github.com/apache/cxf-dosgi/tree/master/samples/rest找到一个示例。

查看 PAX-Web源代码和文档（请参阅User-Guide和Developer-Guide），它似乎不包括对JAX-RS（用于 RESTful Web 服务的 Java API）或JSR 311的支持。

但是，还有许多其他选项可用于在 OSGi 中公开 JAX-RS 端点，例如 RESTeasy、Jersey、Apache CXF等。希望其中之一可用于改进您描述的架构。在各种选项中，至少根据我的经验， CXF 实现似乎是最好的文档，并且很容易与 OSGi 集成。
