我为五罐开发了一个OSGI捆绑包
poi-3.9 - bundle name:- org.apache.poi
poi-ooxml-3.9- bundle name:- org.apache.poi.ooxml
poi-ooxml-schemas
dom4j
xmlbeans
但当我使用这些罐子时，它会给出一个错误
NoClassDef found
org.apache.poi.ss.usermodel.WorkbookFactory
然后我在中实现了一些包（比如org.apache.poi.ss.usermodel）
poi-3.9
poi-ooxml-3.9 jars are same
then i use
Require-Bundle:
org.apache.poi;visibility:=reexport,
org.apache.poi.ooxml;visibility:=reexport
它将给出相同的错误我能做些什么来解决这个问题

首先：您真的需要将poi jar转换成bundle吗？如果只使用另一个bundle中的代码，那么明智的做法是将jar包含到该bundle中，并相应地调整bundle类路径。这可能会为您省去很多问题，尤其是如果您不太熟悉将现有jar转换为OSGi捆绑包的话。
我快速查看了poi分发版，包的名称可能相同，但内容不相同（拆分包）。这意味着，这里最简单的选项是创建一个新的bundle jar，其中包括来自分发版的poi和poi-oxml jar的所有类。然后使用Export-Package标头导出该捆绑包中的所有包。
