可选的捆绑解析

标签： java jackson osgi apache-felix osgi-bundle

我是OSGi的新手。我写了JIRA插件，Apache Felix Bundle。我的捆绑包使用Sprring Framework RestTemplate和Jackson XML进行简单的REST API调用。

所以我使用其他包（在OSGi包含上可用）：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和jackson-annotations（全部在2.6.5版本中），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OSGi包含不明白 com.fasterxml.jackson.core现在可用。

  1. 我应该以某种方式重新加载Apache ServiceMix :: Bundles :: spring-web？
  2. 或者我可能需要以另一种方式来做这件事吗？

    3. 我希望有人可以帮助我。

答案 0 :(得分：1)

如果您的捆绑包具有可选导入，并且您允许它在没有将导入连接到导出器的情况下解析，那么这种情况将持续到您执行“刷新”操作。 OSGi尝试将bundle import / export连接尽可能保持静态，因为重新计算它可能很昂贵，并且还强制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。这可以通过键入refresh命令在Gogo shell中完成。
