下面摘自JDK1。4。1 API: The DataSource interface is implemented by a driver vendor. There are three types of implementations:
Basic implementation -- produces a standard Connection object Connection pooling implementation -- produces a Connection object that will automatically participate in connection pooling. This implementation works with a middle-tier connection pooling manager. Distributed transaction implementation -- produces a Connection object that may be used for distributed transactions and almost always participates in connection pooling. This implementation works with a middle-tier transaction manager and almost always with a connection pooling manager. 不知道是不是所有实现DataSource 的类都已经池化。还是有些池化,请大家指导,谢谢!
