Tomcat（8.0.32）lib目录中的HikariCP（2.4.6）不会记录

Question

当应用程序的战争中捆绑hikari（2.4.6）jar时，日志记录很有效，当我们将它移动到Tomcat（8.0.32）/lib目录时，hikari停止记录。我在hikaricp github (809)中也遇到了类似的问题，其中有一些指导要实现这一目标，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 housekeeper] com.zaxxer.hikari.pool.HikariPool : HikariPool-1 - Pool stats (total=10, active=0, idle=10, waiting=0)

所以我们需要一种方法来在catalina.out

中获取此信息

我的tomcat设置如下：

/lib目录：

和我的logging.properties：

请提供一些有关如何使其正常工作的信息。 非常感谢你

解决方案：

首先，必须将tomcat服务器内部日志记录从Apache Commons Logging更改为log4j。执行此操作的过程描述为here。 假设已阅读上述链接并从extras捆绑包（tomcat-juli-adapters.jar，tomcat-juli.jar）

下载了上述广告

• log4j.properties文件应放在tomcat/lib目录。
• 从logging.properties目录中删除或重命名tomcat/conf文件，因此tomcat在启动时不会将其取回。
• 将以下广告投放到tomcat/lib目录：log4j-1.2.17.jar，tomcat-juli-adapters.jar
• 将以下jar复制并替换为tomcat/bin目录：tomcat-juli.jar

完成上述步骤后，tomcat现在应使用log4j进行记录。

要启用HikariCP日志记录，请执行以下操作：

• 编辑log4j.properties文件，最后添加以下行： log4j.logger.com.zaxxer.hikari = DEBUG
• 确保tomcat/lib目录中存在以下jar：
  • HikariCP-2.4.6.jar
  • JCL-过SLF4J-1.7.21.jar
  • SLF4J-API-1.7.21.jar
  • SLF4J-log4j12-1.7.21.jar
  • 七月到SLF4J-1.7.21.jar

我的log4j.properties文件：
