如何保证某个程序系统内只运行一个，保证原子性

@GetMapping("/startETL")//@Idempotent(expireTime = 90, info = "请勿90秒内连续点击")public R getGaugeTestData6() {log.info("start ETL");//redis设置t_data_load_record 值为2bladeRedis.set("t_data_load_record_type", 2);String s = atomicityService.startETL();return R.data(s);}

@Slf4j@Servicepublic class AtomicityService {@Autowiredprivate DataSourceService dataSourceService;// 使用 AtomicBoolean 作为互斥标志private final AtomicBoolean isExecuting = new AtomicBoolean(false);private final AtomicBoolean isExecutingForXRRJ = new AtomicBoolean(false);public String startETL() {if (isExecuting.compareAndSet(false, true)) {try {long startTime = System.currentTimeMillis(); // 记录开始时间ETLExecutionThreadLocal.setStartTime(startTime);// 执行 ETL 任务的具体逻辑//查询已经存在的数据的 批次号和站点号 做排除用List batchSiteList = dataSourceService.ReadBatchSiteList();List batchList = dataSourceService.ReadBatchList();List testerList = null;//测试人还是全删除吧，不要做增量查询，否则有些人被更新过信息进不来//读取数据源dataSourceService.ReadDataSource(batchSiteList, batchList, testerList);long endTime = System.currentTimeMillis();long executionTimeSeconds = (endTime - startTime) / 1000; // 计算用时（秒）return "ETL执行成功，用时：" + executionTimeSeconds + "秒";} finally {isExecuting.set(false);}} else {// 如果定时任务执行期间有手动执行请求，则驳回log.info("任务已经在执行中，本次请求被驳回");return "任务已经在执行中，本次请求被驳回";}}

定���任务在此与其共用一个程序，两者不可同时执行
