jdbc连接oracle数据库

创建java工程

创建class： ConnectionFactory

创建properties： jdbcInfo.properties

确保oracle连接成功

如：

SQL> sqlplus

SP2-0042: 未知命令 "sqlplus" - 其余行忽略。

SQL> conn zhaod

输入口令:

已连接。

SQL> show user;

USER 为 "ZHAOD"

运行结果为：

oracle.jdbc.driver.T4CConnection@621be5d1

注意获取驱动类：将ojdbc6.jar配置到jar路径下
