原生态连接Oracle数据库的方法

三个步骤：

1、导入oracle数据库连接驱动包：

 
2、配置连接参数如下：
3、测试是否连接成功

package edu.ht.common;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DBConnection {
	private static String url="jdbc:oracle:thin:@localhost:1521:orcl";
	private static String driver="oracle.jdbc.driver.OracleDriver";
	private static String uname="scott"; //用户名
	private static String pwd="ht"; //oracle数据库的密码
	private static Connection conn=null;
		
	static{
		try {
			Class.forName(driver);
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}		
	}
	
	//获取数据库连接
	public static Connection getConnection(){	
		try {
			if (conn==null||conn.isClosed()) {
				conn=DriverManager.getConnection(url, uname, pwd);		
			}
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return conn;	
	}
	
	public static void main(String[] args) {
		System.out.println(DBConnection.getConnection());
		System.out.println("oracle数据，连接成功");
	}
}
