package Util; import java.sql.*; public class DBUtil { public static 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 = "TEACHER"; //連接用戶名 String password = "***"; //連接密碼 Connection con = DriverManager.getConnection(url, user, password); //獲取數據庫連接 if (con != null) { System.out.println("成功的與Oracle數據庫建立連接！！"); } } catch (Exception e) { e.printStackTrace(); } returnconn; //返回Connection實例 } //關閉資源的方法 public static void close(Connection connection ) { try { if (connection != null) { connection.close(); } } catch (SQLException e) { // TODO Auto-generated catch blocke.printStackTrace(); } } public static void close(PreparedStatement preparedStatement ) { try { if (preparedStatement != null) { preparedStatement.close(); } } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public static void close(ResultSet resultSet ) { try { if (resultSet != null) { resultSet.close(); } } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
