在pom文件中添加依赖

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

在Springboot自带的Application启动类所在目录下新建启动类SpringBootStartApplication

package com.huang;import org.springframework.boot.builder.SpringApplicationBuilder;import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;//让该类继承springboot的SpringBootServletInitializerpublic class SpringBootStartApplication extends SpringBootServletInitializer {  @Override  protected SpringApplicationBuilder configure(SpringApplicationBuilder application){    //找到原先的启动类    return application.sources(WebchatApplication.class);  }}

#目录如下src |-main  |-java    |-com.huang.sockerservice    |-WebchatApplication.class #原本的启动类    |-SpringBootStartApplication.class #新的启动类  |-resources
