Virgo 服务器插件解析器冲突

Question

我有两个bundle，A导出两个包，然后B使用这两个包(org.dom4j , org.dom4j.io)，B仍然使用其他bundle导出的spring包。如果我在 osgi 控制台中加载包 A 然后加载包 B，则没有解析器问题。

但是，如果我把这两个包放在一个 par 中，如果在 synthetic.context 包中会失败，说“使用违规：

有人知道如何解决这个问题吗？我尝试制作一个虚拟包，它使用 Import-Bundle 导入两个包的所有导出包，在我手动加载 A 和 B 包后，这些不是解析器错误......

Answer 1

我不熟悉 PAR 文件的部署，使用 Virgo 时我通常会部署 PLAN 文件。这就是说，我怀疑问题可能是由于 A 导出了许多包 org.apache* ，这些包可能已经由 Virgo 中包含的其他包导出，并且是 Spring 的依赖项。因此，当您的 PAR 得到解决时，计划 B 发现自己处于从 A 以及通过传递依赖关系从 Spring 继承相同包的情况。

我会尝试从 A manifest 中删除 Virgo 已经提供的所有包的导出。
