spring boot启动类修改

支持生成pid文件：

    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(ApplicationStart.class);
        springApplication.addListeners(new ApplicationPidFileWriter("xxx.pid"));
        springApplication.run(args);
    }

启动控制脚本
