1、本代码基于定时调度和异步执行同时处理，如果只加异步处理，会导致当前任务未执行完，下个任务到点也不会触发执行

    @Scheduled(fixedRate = 50_000)@Asyncpublic void testThread() throws Exception{ZkLock lock = new ZkLock(zkJob.getZK(), "/vman/analyse_job/lock2");try {if (!lock.acquire(20, TimeUnit.SECONDS)) {log.warn("有其他线程进行分析任务的数据迁移，暂停本次执行");return;}StringBuilder sb = new StringBuilder("处理成功的分析任务id:");Integer startShareId = 1;Integer endShareId   = 100;Integer count = 0;while (startShareId.compareTo(endShareId) <= 0) {try {Thread.sleep(1000);sb.append(startShareId).append(",");} catch (Exception e) {log.info("自助分析任务批量转换异常,jobId:{},exception:{}", startShareId, e);}startShareId++;if (count++ % 20 == 0) {log.info("当前分析任务id:{},转换成功的任务信息:{}", startShareId, sb.toString());sb = new StringBuilder("处理成功的分析任务id:");}}}catch(Exception e) {log.info("定时任务，分析任务转换异常:{}",e);}finally {log.info("关闭分析任务的锁");lock.release();}}

3、使用 jstack 88023 |grep SimpleAsyncTaskExecutor-62 命令可以查看相关线程是否存在，可以看到，相关线程任务执行完成后，会自动消失

4、如果去掉异步，代码如下

 //@Async@Scheduled(fixedRate = 30_000)public void testThread() throws Exception{ZkLock lock = new ZkLock(zkJob.getZK(), "/vman/analyse_job/lock2");try {if (!lock.acquire(20, TimeUnit.SECONDS)) {log.warn("有其他线程进行分析任务的数据迁移，暂停本次执行");return;}StringBuilder sb = new StringBuilder("处理成功的分析任务id:");Integer startShareId = 1;Integer endShareId   = 60;Integer count = 0;while (startShareId.compareTo(endShareId) <= 0) {try {Thread.sleep(1000);sb.append(startShareId).append(",");} catch (Exception e) {log.info("自助分析任务批量转换异常,jobId:{},exception:{}", startShareId, e);}startShareId++;if (count++ % 20 == 0) {log.info("当前分析任务id:{},转换成功的任务信息:{}", startShareId, sb.toString());sb = new StringBuilder("处理成功的分析任务id:");}}}catch(Exception e) {log.info("定时任务，分析任务转换异常:{}",e);}finally {log.info("关闭分析任务的锁");lock.release();}}

发现任务执行的线程只有一个 叫 scheduling-1
