springboot jar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" +

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