手動測試oracle數據庫連接

package com.test.jdbc;

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

public class ConnectionFactory {
public Connection getConnection() {
Connection conn = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver"); //加載數據庫驅動
System.out.println("數據庫驅動加載成功！"); //輸出的信息
String url = "jdbc:oracle:thin:@localhost:1521:orcl"; //獲取連接URL
String user = "scott"; //連接用戶名
String password = "tiger"; //連接密碼
 conn = DriverManager.getConnection(url, user, password); //獲取數據庫連接
if (conn != null) {
System.out.println("成功的與Oracle數據庫建立連接！！");
}
} catch (Exception e) {
e.printStackTrace();
}
return conn; //返回Connection實例
}
public static void main(String[] args) {
ConnectionFactory getConn = new ConnectionFactory();
getConn.getConnection();
}
