如果可以使用虚拟LAN (VLAN)中继，就可以通过同一个物理适配器同时访问多个子网，但是这种方法无法享有这一好处。
If virtual LAN (VLAN) trunking is available, where multiple network subnets can be accessed simultaneously through the same physical adapter, this method does not use that benefit.
对于JTA EntityManager, JTA事务被传递到底层的资源管理器(即虚拟数据库，由它将这个事务中继到物理数据库)。
For a JTA EntityManager, the JTA transaction is propagated to the underlying resource manager (i.e., the virtual database, which relays the transaction to physical databases).
