可选的捆绑分辨率
Optional bundle resolution
我是 OSGi 新手。我写了 JIRA 插件，它是 Apache Felix Bundle. My bundle uses Sprring Framework RestTemplate and Jackson XML 用于简单的 REST API 调用。
所以我使用其他包（在 OSGi 容器上可用）：Apache ServiceMix :: Bundles :: spring-web 将 <Import-Package> 设置为 com.fasterxml.jackson.*; version="[2,3)";resolution:="optional"
我在 OSGi 容器上安装了 jackson-databind, jackson-core and jackson-annotations（全部在版本 2.6.5 中）以提供缺少的可选依赖项。
我的 github.
上提供了完整的源代码
当我安装我的插件时一切正常，但在运行时我收到错误：

看起来像 OSGi 容器 不知道 com.fasterxml.jackson.core 现在可用了。
- 我应该重新加载
Apache ServiceMix :: Bundles :: spring-web 吗？
- 或者我可能需要用另一种方式来做？
我希望有人能帮助我。
如果您的包有一个可选的导入，并且您允许它在没有将导入连接到导出器的情况下解析，那么这种情况将一直持续到您执行 "refresh" 操作。 OSGi 尝试让 bundle import/export 布线尽可能保持静态，因为重新计算的成本很高，而且它还会强制 bundle 重新启动。
因此，如果您希望 OSGi 连接到现在可用的导入，则需要刷新。这可以在 Gogo shell 中通过键入 refresh 命令来完成。
