Spring Boot应用程序已部署，但不会在Tomcat 8中启动

Question

我一直致力于将SpringBootWeb应用程序与Jenkins和Tomcat9集成在一起。当我在Eclipse中作为spring boot应用程序运行时，一切似乎都很好。

我现在正在建立Jenkins和一个测试/质量保证/展示和告知环境。当我试图在独立的Tomcat9环境中部署war时，我的应用程序无法正常启动。

我遵循了Spring Boot文档，让Eclipse为我完成了Tomcat集成的大部分工作。我还使用以下线程作为检查表。。。如何在tomcat服务器上部署spring boot web应用程序

我在我的开发机器和我的目标环境上得到了相同的堆栈跟踪，詹金斯和汤姆卡特9作为服务运行。

Answer 1

尝试驱动程序类名：com.cj.mysql.jdbc.驱动程序

Answer 2

这是由我的伐木罐冲突引起的...我注释了maven log4j2依赖项，并切换到Logback。
