java基於JDBC連接Oracle 11g Release2實例分析

 　　本文實例講述了java基於JDBC連接Oracle 11g Release2的方法。分享給大家供大家參考。具體如下：

　　Oracle 11g Release 2 的 JDBC 連接似乎有所不同 ，如果你收到下面的異常：

　　Listener refused the connection with the following error:ORA-12505, TNS:listener does not currently know of SID given in connect descriptor.

　　那麼你必須用下面的連接方式：

　　希望本文所述對大家的java程序設計有所幫助。
