两种分布式Redis锁异同

@Slf4j
public class DisLock {
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;
    // 一   RedisTemplate
    public void oneLock(){
        String key = "key-001";
        Long currentTime = System.currentTimeMillis();
        boolean lock = redisTemplate.opsForValue().setIfAbsent(key, currentTime);
        try {
            if (lock) {
                log.info("获取锁成功，开始逻辑处理");
            }else{
                log.info("获取锁失败，业务正在处理中，请稍后");
            }
        }catch (Exception e){
            log.error("系统异常",e);
        }finally {
            if (lock) {
                redisTemplate.delete(key);
                log.info("处理结束，释放锁!");
            } else {
                log.info("没有获取到锁，无需释放锁!");
                Long createTime = (Long) redisTemplate.opsForValue().get(key);
                Long nowTime = System.currentTimeMillis();
                Long time = (nowTime - createTime) / 1000;
                log.info("没有获取到锁，检测获取锁的线程是否处理超时，超时则释放他的锁");
                if (time > 10) {//自定义锁多久自动释放锁
                    redisTemplate.delete(key);
                    log.info("逻辑处理超过20秒，释放锁！");
                }
            }
        }
    }
    //二 jds
    public void twoLock() {
        //基于redis的分布式锁
        String redisKey = "key-001";
        boolean falg = false;
        try {
            Long lock = this.incrBy(redisKey, 1, 10);//一次，超时时间10秒
            if (lock > 1) {
                log.info("请勿重复提交请求");
            }
            log.info("逻辑处理开始。。。。");
        } catch (Exception e) {
            log.error("#accumulatePoints() 出现异常:{}", e);
        } finally {
            if(falg) {
                this.del(redisKey);
            }
        }
    }

    static ShardedJedisPool pool;
    public static Long incrBy(String key, long num, int seconds) {
        ShardedJedis jds = null;
        jds = pool.getResource();
        Long result = jds.incrBy(key, num);
        if (seconds > 0) {
            jds.expire(key, seconds);
        }
        return result;
    }
    public static void del(String key) {
        ShardedJedis jds = null;
        try {
            jds = pool.getResource();
            jds.del(key);
        } catch (Exception e) {
            log.error("#RedisPool() del异常：", e);
            e.printStackTrace();

        }
    }

}

后者，分两步，设置过期时间，会出现过期时间没有设置上，导致永久有效。。。

补充：业务未执行结束，延期

自己定义个线程，进行监控。快过期没有执行完进行延期。

Thread.currentThread() 获取当前线程

Thread.currentThread().start() 获取当前线程运行状态

if (Thread.State.TERMINATED == Thread.currentThread().start() ) {判断线程是否结束

结束解锁 未结束延期
