osgi - 在 Felix.missing requirement [5.0] osgi.wiring.package 中启动 bundle 时出现问题； (osgi.wiring.package=com.sun.jersey.api.core)

Question

我正在使用 maven-bundle-plugin 构建一个 war 文件作为一个包，我想在 Felix 中部署它。这是相同的 POM 文件。

当我使用 maven install 构建它时，我可以在 war 包的 META-INF 文件夹中看到一个逻辑上正确的 MANIFEST.MF 文件。这是 MANIFEST.MF。

但是当我在 Apache Felix 中部署并启动它时，我看到以下错误。

啊! org.osgi.framework.BundleException: bundle war-bundle [5] 中 Unresolved 约束:无法解决 5.0:缺少要求 [5.0] osgi.wiring.package； (osgi.wiring.package=com.sun.jersey.api.core)

包 com.sun.jersey.api.core 是 jersey-core-1.11.jar 的一部分，它已经在 MANIFEST.MF 的 Bundle-ClassPath 中提到，那么为什么我会收到此错误？

如果我开始放置相应的捆绑文件，例如 jersey-core-1.11.jar 的 bundle ，那么问题就解决了，但我认为这不是一个很好的解决方案。事实上，为此目的，只提供了 maven bundle 插件和标签。

请指教。

Answer 1

快速查看 MANIFEST 文件后，我发现 有一个用于 com.sun.jersey.api.core 的导入包。我想你也嵌入了这个包，但这对这种依赖没有影响。如果你要求依赖，你会得到它

只需将其删除即可，在 Maven 中，您可以将其从 Import-Package 行中删除。

此外，您确实嵌入了很多东西。我认为在 webapp 中嵌入 servlet api 不是一个好主意，因为应用程序服务器提供了它。它可能有效，但在部署到其他应用程序服务器时可能会遇到麻烦。
