本文详细介绍如何将Spring Boot应用打包成WAR格式，并部署到Tomcat服务器上。具体步骤包括：修改pom.xml中的打包类型为WAR，配置Spring Boot应用以继承SpringBootServletInitializer，排除并重新引入spring-boot-starter-tomcat依赖，配置maven-war-plugin，以及调整资源文件的打包路径。

1.修改打包格式war

2.修改代码入口

@SpringBootApplication
@MapperScan("com.example.demo.dao")
public class DemoApplication extends SpringBootServletInitializer {

   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

      return application.sources(DemoApplication.class);
   }

   public static void main(String[] args) {
      SpringApplication.run(DemoApplication.class, args);
   }
}

3.添加引用
