我有一个弹簧启动项目，在此之前我总是将它打包到一个jar文件中并按此运行：
java -jar myjar.jar
现在我想将它转换为war包并将其部署到tomcat中。我跟着这篇文章：
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#build-tool-plugins-maven-packaging
但当我尝试将其部署到tomcat时，我收到了错误：

任何可以帮助我的人？提前谢谢！

就我而言，我有两个类在Spring Boot扫描的同一包中扩展了'SpringBootServletInitializer'。即使删除其中一个类的@SpringBootApplication或@ComponentScan也无效。只留下一个类，经过编译后它又可以工作了。

添加@SpringBootApplication或@Configuration TeacService类，它将对我来说很好用，请检查该答复是否对您不起作用。
答案 2 :(得分：-2)
由于我的部署在公司平台上，我的问题解决了，因为项目的解包地址不正确
