### Question:
RedisLockUtil { public static boolean releaseDistributedLock(Jedis jedis, String lockKey, String requestId) { String script = "if redis.call('get', KEYS[1]) == ARGV[1] then return redis.call('del', KEYS[1]) else return 0 end"; Object result = jedis.eval(script, Collections.singletonList(lockKey), Collections.singletonList(requestId)); return RELEASE_SUCCESS.equals(result); }  static boolean tryGetDistributedLock(Jedis jedis, String lockKey, String requestId, int expireTime); static boolean releaseDistributedLock(Jedis jedis, String lockKey, String requestId);  }### Answer:
@Test public void releaseDistributedLockTest() throws Exception { String key = "testDistributedLockKey"; String requestId = UUID.randomUUID().toString(); boolean releaseDistributedLockResult = RedisLockUtil.releaseDistributedLock(JEDIS, key, requestId); System.out.println("releaseDistributedLockResult=" + releaseDistributedLockResult); Assert.assertTrue(releaseDistributedLockResult); }
