import javax.activation.DataSource与import javax.sql.Datasource的区别

import javax.activation.DataSource：
中定义的接口都跟I/O有关，其实现类也打多与网络、文件I/O相关，可以判断出，import javax.activation.DataSource是对资源文件的抽象，类似Reader、Writer等。
import javax.sql.Datasourcede：
是JDBC2.0标准中的规范，其目的是针对1.0标准中通过DriverManager.getConnection()方式获取到的数据库链接，消耗大、不可复用等缺点而推出的新一代规范。javax.sql.DataSource接口方法也只有两个：有参和无参的getConnection()方法。具体的实现有DruidDataSource和BasicDataSource(apache)等。这些数据源能提供可复用方式的数据库链接，大多采用连接池实现，好处就是:资源可以复用。
