oracle jdbc connection

今天回过头来看看oracle jdbc连接，总结了一下，以供以后复习回顾；

oracle是11g的，导入ojdbc14.jar架包，用用户名和密码，和端口，和sid标识；

package com.oracle.conn;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.Statement;

public class TestConn {

public static final String
userName = "xxx";

public static final
String password = "manager";

public static final String URL =
"jdbc:oracle:thin:@localhost:1521:myOracle";

public static void main(String[] args) throws
Exception {

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();

// 创建连接

Connection conn =
DriverManager.getConnection(URL, userName, password);

// 创建语句执行体

Statement stm
= conn.createStatement();

// 发送sql语句

String sql = "select
userId,userName from xxx";

ResultSet rs =
stm.executeQuery(sql);

// 处理结果集

while (rs.next()) {

System.out.println(rs.getString("userId")
+":"+ rs.getString("userName"));

}

rs.close();

// 关闭资源

stm.close();

conn.close();

System.out.println("success");

}

}

到此处所有的完成，运行main方法，就ok....
