在`org.dromara.raincat.core.service.impl.TxManagerLocator`中存储server列表的部分使用的是`AtomicReference`。这里的修改部分又加了锁，如果不用原子类，直接用`volatile`不可以吗。

这个事务框架应该不能算是“二阶段提交”

作者你好，看了一下happylifeplat-transaction的实现，感觉你这个事务框架好像还不能算是“二阶段提交”啊。二阶段提交针对的是事务框架对资源管理器/数据库的协调过程，真正执行二阶段提交的应该还是底层的数据库。原理可以参考：[二阶段提交原理图](https://static001.infoq.cn/resource/image/76/40/76a6d8e35ec97e1723b785a13a54a940.png)。 而happylifeplat-transaction在提交事务时，采用的仍然是资源管理器的一阶段提交。只不过在发起提交之前，先判断了一下节点间网络通道的状态等信息，但这种框架自己内部的判断，应该不能算是一个提交的阶段啊。不然，二阶段提交岂不是分分钟改成三阶段提交了？二阶段、三阶段也就没啥太大差别、也不具备任何意义了。不知道我理解的对不对，求解惑~

raincat-manager起到事务协调器的作用的话 raincat-admin只是起到一个管理后台的作用吗？ 为什么不把他们俩个合并成一个？ 因为manager已经集成了eureka-server吗
