先说下业务场景，业务1：基于实时轨迹数据打卡，业务2：基于非实时轨迹的时间差，计算累计时长。 简单点说就是从websocket获取到的实时数据，既要兼容不耗时操作，又要兼容耗时操作。

单线程做的话，一两个用户的数据没问题，用户多了就处理不过来。

实现思路是用TaskExecutor来做，一个task接收从redis lPop的数据，并放入BlockingQueue，另外的task从BlockingQueue获取数据。

@Autowiredprivate TaskExecutor taskExecutor1;@Autowiredprivate TaskExecutor taskExecutor2;@Autowiredprivate TaskExecutor taskExecutor3;static BlockingQueue<TrackHistory> dataQueue = new ArrayBlockingQueue<>(1 << 12);static BlockingQueue<TrackHistory> keepWatchQueue = new ArrayBlockingQueue<>(1 << 12);public static final String M = ":";@Bean("redisReadThread")public String service() {taskExecutor1.execute(() -> {while (true) {try {lPop();} catch (Exception e) {e.printStackTrace();}}});return null;}@Bean("calculationsBusinessData")public void calculationsService() {taskExecutor2.execute(() -> {while (true) {try {if (dataQueue.size() != 0) {TrackHistory trackRealTime = dataQueue.poll();if (trackRealTime == null) {Thread.sleep(100L);} else {//耗时方法doSomething();//存储当前日期+人员的最新位置坐标saveTrackToRedis(trackRealTime);}} else {Thread.sleep(100L);}} catch (Exception e) {log.error("业务1数据计算异常->{}", e.getMessage());}}});}@Bean("calculationsKeepWatch")public void keepWatchService() {taskExecutor3.execute(() -> {while (true) {try {if (keepWatchQueue.size() != 0) {TrackHistory trackRealTime = keepWatchQueue.poll();if (trackRealTime == null) {Thread.sleep(100L);} else {doSomething2(trackRealTime);}} else {Thread.sleep(100L);}} catch (Exception e) {log.error("业务2数据计算异常->{}", e.getMessage());}}});}/*** 从队列中读取数据** @return*/private synchronized void lPop() {Object o = redisTemplate.opsForList().leftPop(RedisKeyCons.COORDINATE);if (!org.springframework.util.StringUtils.isEmpty(o)) {TrackHistory trackRealTime = (TrackHistory) o;log.info("leftPop trackHistory = {}", trackRealTime);if (null != trackRealTime) {if (checkMemberExist(trackRealTime)) {return;}//存储当前日期+人员的最新位置坐标saveTrackToRedisForKeepWatch(trackRealTime);dataQueue.add(trackRealTime);keepWatchQueue.add(trackRealTime);}}}

配置线程池
