Java 从控制台启动OSGI时Log4j2不工作（在Eclipse中工作）

我使用log4j2编写了一个日志程序，并在eclipse上运行。我没有使用任何xml文件进行配置，而是以编程方式修改默认配置。我正在OSGi环境中使用声明性服务进行开发

当我从控制台运行OSGi并启动记录器包时，没有错误。但当我启动另一个正在使用此记录器捆绑包服务的捆绑包时，会显示一个错误，显示：

Caused by: java.lang.ClassNotFoundException: javax.naming.NamingException 

我把整个错误日志放在这里，以防它提供详细信息。因此，捆绑包将无法解析。这个问题的原因可能是什么

这实际上是一个bug。LOG4J2在OSGi环境中有类加载器问题，与中一样，也是类似的问题

我以前使用的是下载版本apache-log4j-2.0-rc2-bin。 但现在有了一个新版本apache-log4j-2.0.2-bin，它在OSGi环境下运行。但是为了正确解析带有LOG4j2的包，我必须导入“org.osgi.framework.willing”

---

它仍然向我显示错误“无法重新配置JMX java.lang.NoClassDefFoundError:javax/management/ObjectName…”，我仍然需要找到解决方案，但至少它在从控制台启动的OSGi环境中运行。

我刚刚检查了是否可以调用LogManager.getLogger（），它对我有效。您能提供一个示例（您的环境打包成一个zip或log4j初始化的代码片段）来重现这个问题吗？我已经尝试过删除所有初始化，但仍然是一样的。我首先获取包含Log4j2的包实例，然后调用一个执行LogManager.getLogger（）的方法。您使用过相同的方法吗？据我所知，它在调用静态方法LogManager.getLogger（）时失败。我在从命令行开始的equinox环境中也调用了它。静态方法调用运行良好，并且出现了日志。这就是为什么我问你是否可以打包失败的样本。我找不到将样本打包到stackoverflow的选项。这就是我用代码片段编辑主要问题的原因。你看到我添加的部分代码了吗？@balazsoldos我从这里的链接中注意到，Log4j2中有一个bug，当嵌入到OSGi中的另一个包中时，会出现类加载器问题。也许你有一个可以用的罐子。你能给我你的Log4j2罐子的链接吗？你有多少jar文件？非常感谢。
