Spring引导WebApplication在Tomcat 7服务器上启动两次

我有Spring引导WebApplication，我可以在没有安装Tomcat的情况下单独启动，因为它本身嵌入了Server，对吗？所以正常启动时，我就可以在Eclipse中单击鼠标右键并选择：运行方式/ SpringBootAppSpring引导WebApplication在Tomcat 7服务器上启动两次

但是当我添加它的Tomcat 7的server.xml是启动两次。所以我假设它首先从他的嵌入式服务器开始，然后尝试在Tomcat 7中启动？

下面是日志：

你是否遵循了Spring Boot的[传统部署指南]（https://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html）？ –

是的，spring-boot-starter-tomcat在pom.xml中提供提供 –

万一management.port从server.port第二嵌入式servlet容器被旋转了配置有所不同。在进行传统的战争文件部署时，您不能使用这两个选项。
