java - Tomcat(8.0.32) lib 目录中的 HikariCP(2.4.6) 不记录

Question

虽然当 hikari(2.4.6) jar 捆绑在应用程序的 war 中时日志记录工作得很好，但当我们将它移动到 Tomcat(8.0.32) /lib 时目录，hikari 停止记录。我在 hikaricp github (809) 中关注了类似的问题在实现这一目标方面有一些指导，但我无法让它发挥作用。对于我们的应用程序，监控池非常重要:

2017-02-01 12:27:17.274 DEBUG 26240 --- [l-1 管家] com.zaxxer.hikari.pool.HikariPool:HikariPool-1 - 池统计(总数=10， Activity = 0, 空闲=10, 等待=0)

所以我们需要一种方法在 catalina.out

中获取此信息

我的 tomcat 设置如下:

/lib目录:

请向我提供一些有关如何使其正常工作的信息。 非常感谢

解决方法:

首先，必须将tomcat服务器内部日志记录从Apache Commons Logging改成至 log4j .描述了执行此操作的过程 here . 假设已阅读上面的链接并从 extras 包中下载上述 jar(tomcat-juli-adapters.jar、tomcat-juli.jar )

• log4j.properties 文件应该放在tomcat/lib 目录下。
• 从 tomcat/conf 目录中删除或重命名 logging.properties 文件，这样 tomcat 就不会在启动时获取它。<
• 将以下 jar 复制到 tomcat/lib 目录:log4j-1.2.17.jar、tomcat-juli-adapters.jar
• 将以下 jar 复制并替换到 tomcat/bin 目录:tomcat-juli.jar

完成上述步骤后，tomcat 现在应该使用 log4j 进行日志记录。

要启用 HikariCP 日志记录，请执行以下操作:

• 编辑 log4j.properties 文件并在末尾添加以下行: log4j.logger.com.zaxxer.hikari = DEBUG
• 确保以下 jar 存在于 tomcat/lib 目录中:
  • HikariCP-2.4.6.jar
  • jcl-over-slf4j-1.7.21.jar
  • slf4j-api-1.7.21.jar
  • slf4j-log4j12-1.7.21.jar
  • jul-to-slf4j-1.7.21.jar

我的 log4j.properties 文件:
