redis-分布式锁样例

redisTemplate：

string lockKey = "product_101"
string clientID = UUID.randomUUID().toString()
bool result = redisTemplate.opsForValue().setIfAbsent(lockKey,clientID,10,TimeUnit.SECONDS)
if(!result)
{
  return "error_code"
}
try{
//业务逻辑
}finally{
  if(clientID.equals(redisTemplate.opsForValue().get(lockKey)))
  {
  redisTemplate.delete(lockKey)
  }
}

与注意事项对应关系如下所示

redisson:

redissonLock = redisson.getLock(lockKey);
redissonLock.lock();
try{
//   逻辑
}finally{
  redissonLock.unlock();
}
