Java-Jdbc,JDBC连接Oracle11g实例:

很长时间没用Oracle数据库了,今天在公司的电脑上装了一个Oracle11g,安装完成后,顺便写了个简单的Jdbc连接Oracle的例子,现在记录一下,方便以后查看:


例子很简单,直接上代码:

(注意:在测试之前要先把Oracle的驱动jar放到你建立的工程的lib下)

一:JdbcUtil.java

package cn.gov.csrc.base.util;

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

public class JdbcUtils {
	
	private static final String driverUrl = "oracle.jdbc.driver.OracleDriver";

	private static final String url = "jdbc:oracle:thin:@localhost:1521:ORCL";
	
	private static final String username = "CSRC";
	
	private static final String password = "CSRC";
	
	public static Connection getConnection(){
		Connection connection = null;
		try {
			Class.forName(driverUrl);
			connection = DriverManager.getConnection(url, username, password);
			connection.close();
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}
		return connection;
	}
	
	// 测试Oracle连接是否成功
	public static void main(String[] args) {
		Connection connection = JdbcUtils.getConnection();
		System.out.println("连接成功:"+connection);
	}
	
}


二:测试结果:

连接成功:oracle.jdbc.driver.T4CConnection@481adc30
