java Log4j2抛出NoSuchMethodError

6 月，2 周 Questions & Answers 2604

我从log4j22.0-beta9升级到了2.0，包括log4j-core和log4j-api

我的应用程序以前运行良好，现在出现以下错误：

Caused by: java.lang.NoSuchMethodError: org.apache.logging.log4j.core.Logger.log(Lorg/apache/logging/log4j/Marker;Ljava/lang/String;Lorg/apache/logging/log4j/Level;Lorg/apache/logging/log4j/message/Message;Ljava/lang/Throwable;)V
    at org.apache.log4j.Category.forcedLog(Category.java:336)
    at org.apache.log4j.Category.log(Category.java:423)
    at com.mchange.v2.log.log4j.Log4jMLog$Log4jMLogger.log(Log4jMLog.java:171)
    at com.mchange.v2.log.log4j.Log4jMLog$Log4jMLogger.log(Log4jMLog.java:183)
    at com.mchange.v2.cfg.MConfig.dumpToLogger(MConfig.java:101)
    at com.mchange.v2.cfg.MConfig.dumpToLogger(MConfig.java:98)

    at com.mchange.v1.cachedstore.NoCleanupCachedStore.find(NoCleanupCachedStore.java:63)

这里可能出了什么问题？为什么log4j会失败

也许我必须从c3p0重定向日志记录？如何在log4j2中编写以下语句

com.mchange.v2.log.MLog=com.mchange.v2.log.log4j.Log4jMLog

我发现以下语句将阻止c3p0日志记录，因此是我当前的解决方法：

System.setProperty("com.mchange.v2.log.MLog", "com.mchange.v2.log.FallbackMLog");

但我希望将日志重定向到log4j2，因此仍在寻找解决方案

有 Java 编程相关的问题?
