需要注意的是，在ORACLE的官方网站上，针对每一个数据库大版本中细分的若干小版本的JDBC Drivers，虽然JDBC Drivers包的文件名相同，但文件的大小却有区别，举例如下：
Oracle Database11g Release 2 (11.2.0.1.0) JDBC Drivers     ojdbc5.jar (1,996,228 bytes)
Oracle Database11g Release 2 (11.2.0.2.0) JDBC Drivers     ojdbc5.jar (2,030,135 bytes)
由于时间有限，没有对其差别进一步研究，但在开发过程中，为保证好的兼容性，应根据所使用的ORACLE具体版本到官方网站上下载相对应的JDBC Drivers包。
