UnpooledDataSource类

UnpooledDataSource每次实时获取connection

核心流程

UnpooledDataSource#getConnection(java.lang.String, java.lang.String)

->

UnpooledDataSource#doGetConnection(java.lang.String, java.lang.String)

设置

props.setProperty("user", username);

props.setProperty("password", password);

->

UnpooledDataSource#doGetConnection(java.util.Properties)

初始化驱动：initializeDriver();
获取数据库连接：Connection connection = DriverManager.getConnection(url, properties);
设置连接属性：configureConnection(connection);

->

UnpooledDataSource#configureConnection

设置超时时间：使用了Executors.newSingleThreadExecutor()等待数据库操作完成
