JDBC操作Oracle數(shù)據(jù)庫(增刪改查詳細(xì)實例教程)

1、private finalStri ng = oracle.jdbc.driver.OracleDriver及登錄；功能實現(xiàn)。Eclipse + Struts2+oracle+jdbceb 開發(fā)技術(shù)框架入門小項目，一般都是從增刪改功能實現(xiàn)開始入手，就像學(xué)編程語言幾乎從“HelloWorld fin al” 一樣的經(jīng)典，本人初入String = jdbc:oracle:thi n: 9:1521:denver;private final StringDBUSER=zzw;private final 一、環(huán)境搭建zzw;private Conn ectionCOnn= n u
