pom

        
            org.springframework.boot
            spring-boot-starter-tomcat
            provided
        



          org.springframework.boot
          spring-boot-starter-web
      

   org.springframework.boot
    spring-boot-starter-tomcat
    provided

如果有servlet，还需要引入此jar包

     
      javax.servlet
      javax.servlet-api
      provided
