3:需要准备2个jar包 classes12.jar jedis-2.1.0-sources.jar
好像还有个jar包;我忘了;;
我也刚学习没多久,这代码你直接拷贝过去;需要改下类名,引用的包,数据库的配置项,sql语句;等等就可以用了
Connection conn = null;
Class.forName("oracle.jdbc.driver.OracleDriver");//加入oracle的驱动,“”里面是驱动的路径
String url = "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL";// 数据库连接,oracle代表链接的是oracle数据库;thin:@MyDbComputerNameOrIP代表的是数据库所在的IP地址(可以保留thin:);1521代表链接数据库的端口号;ORCL代表的是数据库名称
String UserName = "root";// 数据库用户登陆名 ( 也有说是 schema 名字的 )
String Password = "2006";// 密码
conn = DriverManager.getConnection(url, UserName, Password);
首先安装ORACLE10或者11g
利用SQL语句创建或者PLSQL等工具图形界面创建数据库
使用JDBC方式连接数据库
建议去BJSXT去下个马士兵讲的oracle视频吧
public static void main(String[] args) throws ClassNotFoundException, Exception {
Class.forName("com.mysql.jdbc.Driver");//加载驱动类
//创建连接
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/bdtm_db", "username", "password");
//创建 statement
Statement st = conn.createStatement();
//执行sql
st.execute("sql...");
//创建 预编译的statement 可以防止sql注入
PreparedStatement ps = conn.prepareStatement("select * from table where id = ?");
//设置参数
ps.setInt(1, 1);
//执行
ps.executeQuery();
//关闭 释放资源
st.close();
ps.close();
conn.close();
}
