spring boot war包 使用外置jetty9?报错

spring boot 打好的war包怎么在jetty9里运行，没有执行Application里的方法？这样写也没执行。。

@EnableTransactionManagement
@SpringBootApplication
public class KBaseLiveMgrApplication extends SpringBootServletInitializer {

    private static final Log logger = LogFactory.getLog(KBaseLiveMgrApplication.class);

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        logger.info("KBaseLiveMgrApplication builder");
        return builder.sources(KBaseLiveMgrApplication.class);
    }

    public static void main(String[] args) {
        logger.info("KBaseLiveMgrApplication main");
        SpringApplication.run(KBaseLiveMgrApplication.class, args);
    }
}

日志：

运行没报错，但是：
