如何把springbootjar项目改为war项目

@SpringBootApplication
public class JeewxBootApplication extends SpringBootServletInitializer {
  public final static Logger log = LoggerFactory.getLogger(JeewxBootApplication.class);

  public static void main(String[] args) {
    ConfigurableApplicationContext application = SpringApplication.run(JeewxBootApplication.class, args);
    Environment env = application.getEnvironment();
    String ip = InetAddress.getLocalHost().getHostAddress();
    String port = env.getProperty("server.port");
    String path = env.getProperty("server.servlet.context-path");
    log.info("\n----------------------------------------------------------\n\t" +
      "Application is running! Access URLs:\n\t" +
      "Local: \t\thttp://localhost:" + port + path + "/\n\t" +
      "External: \thttp://" + ip + ":" + port + path + "/\n\t" +
      "----------------------------------------------------------");
  }

  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(JeewxBootApplication.class);
  }

}
