The logical judgment here is considered as follows:

1. The ECM tag is not locked first for resource judgment. If the resource is judged, it will continue. Therefore, there is a certain probability of negative resources, but there will not be too many situations.
2. The reason for this consideration is to reduce lock waiting, because here is a concurrent lock grab, so the lock granularity should be as small as possible to reduce concurrency pressure.
3. If the usercreator lock is placed at a higher level, it will cause more lock waits.

这里的逻辑判断是这样考虑的：

1. ECM标签先不锁进行资源判断如果资源判断过就继续，所以存在一定概率出现负资源，但是不会出现太多情况
2. 之所以这样考虑是为了减少锁的等待，因为这里是并发抢锁的，所以锁的粒度尽量小减少并发压力
3. 如果把usercreator的锁放到更上一层，会导致更多的锁等待
