问题：日志的路径没有生效，始终在根目录产生日志文件。

没有用tomcat容器的方式启动程序

在 Servlet API 中有一个 ServletContextListener 接口，它能够监听 ServletContext 对象的生命周期，实际上就是监听 Web 应用的生命周期。

当Servlet 容器启动或终止Web 应用时，会触发ServletContextEvent 事件，该事件由ServletContextListener 来处理。在 ServletContextListener 接口中定义了处理ServletContextEvent 事件的两个方法。

如果你有多个ServletContextListener，其中一些是在部署描述符中声明的和其他带注释的人，然后在 web.xml 中定义的侦听器将获得优先权。

根据类名的排序来执行。
