当我在 maven (m2e) 中使用 logback 时出现以下错误。Environment: JBOSS 7.1.1,maven,eclipse。但如果我只是作为主类单独运行，它就可以正常工作。我无法弄清楚为什么会出现此错误，任何人都可以帮助我解决此问题并找到解决方案。

该错误表明com.zreflect.emyed.whiteboard.pubsub.EventLoggerAsync该类期望 a ch.qos.logback.classic.LoggerContext，而不是它获得 a org.slf4j.helpers.NOPLoggerFactory。这通常发生在某些代码尝试强制转换的返回值org.slf4j.LoggerFactory.getILoggerFactory并且 slf4j 绑定到 NOP 实现时，因为类路径上没有可用的 slf4j 绑定。这通常伴随着一条错误消息。
