osgi - 将 Swagger 2.0 与 Glassfish 4.1 OSGi REST 项目集成

Question

我是否需要专门包含 JAX-RS 和 HttpServlet jar 才能将 Swagger 2.0 集成到我的 JAX-RS 项目中？

我试图展示我按照以下规范开发的 RESTful 服务:

• Java
• NetBeans IDE 8.0.2 [Maven]
• OSGi 4.2
• 项目以 JSON 格式交换信息
• 玻璃鱼4.1
• JAX-RS 2.0
• Jersey 2.0

该项目成功部署到 Glassfish 上，但是当调用任何 REST 服务时，它会抛出错误 404。服务器日志提示类加载错误，特别是 javax.ws.rs.*(尽管有 javax.ws.rs -提供的api)，并产生 java.lang.NoClassDefFoundError:javax/ws/rs/core/Application

目前已完成的工作:

• 更新了 Glassfish 4.1 以包含 Jersey 2 和 JAX-RS 2
• 所有 Jersey-Glassfish 依赖项均标记为“已提供”
• 解决了重复的依赖关系

Answer 1

确保 javax.ws.rs.* 包由系统 bundle 提供。您可以连接到OSGi Module Management Subsystem使用 Felix Gogo Remote Shell 运行 glassfish 并使用内置命令查询注册表。
