从控制台启动OSGI时Log4j2无法正常工作（在Eclipse中工作）

时间：2014-08-21 21:41:53

标签： java eclipse log4j osgi log4j2

我有一个使用log4j2在eclipse上运行的日志记录程序。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。我正在使用声明式服务在OSGi环境中开发。

当我从控制台运行OSGi并启动记录器包时，没有错误。但是，当我启动另一个使用此记录器捆绑服务的捆绑包时，会显示错误，显示：

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

我将整个错误日志放在这里，以防它提供详细信息。因此捆绑将无法解决。可能是造成这个问题的原因是什么？

编辑：

我在一个简单的设置中尝试使用LogManager.getLogger（）而没有配置代码（左边是默认值），但结果仍然相同。如果我没有调用包含“LogManager.getLogger（）”的方法，则包含Log4j2的包只会解析。

....Inside logger...
private static Logger m_Logger;
public void setClassName(String className) 
    {
    //Logger m_Logger = LogManager.getLogger(className); 
    Logger m_Logger = LogManager.getLogger(); 
    m_Logger.error("Logger program working");
    }
....Inside consuming bundle...
protected void OSGiLoggerBind (OSGiLogger myLogger)
    {
    m_LoggerService = myLogger;
m_LoggerService.setClassName(OSGiLoggerTest.class.getName());
    }

1 个答案:

答案 0 :(得分：0)

这实际上是一个错误。 LOG4J2在OSGi环境中具有类here中的类加载器问题，同样here也存在类加载器问题。

我之前使用的是下载版本apache-log4j-2.0-rc2-bin。 但现在有一个新版本here apache-log4j-2.0.2-bin，它在OSGi环境下运行。但是对于正确解析LOG4j2的包，我必须导入“org.osgi.framework.wiring”。

它仍然显示错误“无法重新配置JMX java.lang.NoClassDefFoundError：javax / management / ObjectName ....”我仍然需要找到它的解决方案，但至少它在OSGi环境中运行从控制台开始。
