java實現JDBC連接MySql及引用驅動程序包

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

public class ConnectToDataBase {
	public static Connection getDataBaseConnection(){
		String driver="com.mysql.jdbc.Driver";
		String url="jdbc:mysql://localhost:3306/db_pms";
		String user="root";
		String password="123456";
		
		//加載驅動程序
		try {
			Class.forName(driver);
			//URL：http://www.bianceng.cn/Programming/Java/201608/50376.htm
			//System.out.println("驅動程序加載成功");
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		}
		
		//鏈接數據庫
		Connection conn=null;
		try {
			conn=DriverManager.getConnection(url, user, password);
			if (!conn.isClosed()) {
				System.out.println("連接數據庫成功");
			}
		} catch (SQLException e) {
			System.out.println("鏈接數據庫失敗: "+e.getMessage());
		}
		
		return conn;
	}
	
}

   Connection  conn=ConnectToDataBase.getDataBaseConnection();
