当应用程序的war中捆绑了
hikari
（2.4.6）jar时，日志记录工作很好，但当我们将其移动到Tomcat（8.0.32）
/lib
目录时，
hikari
停止日志记录。我在hikaricp github关注过一个类似的问题，在那里有一些实现这一点的指导，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：

因此，我们需要一种在catalina.out中获取此信息的方法

我的tomcat设置如下所示：

请给我提供一些如何让这个工作的信息。 非常感谢

解决方案：

首先，tomcat服务器内部日志必须从更改为。描述了执行此操作的步骤。 假设已经阅读了上面的链接并从
extras
包下载了上述jar（
tomcat juli adapters.jar
，
tomcat juli.jar
）

  • log4j.properties
    文件应放在
    tomcat/lib
    目录下
  • 从
    tomcat/conf
    目录中删除或重命名
    logging.properties
    文件，这样
    tomcat
    在启动时不会拾取它
  • 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
