问题描述

public Connection MySqlConnection(){

        Connection conn=null;
        try{
            Class.forName("com.mysql.jdbc.Driver");
            conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/project","root","root");
            return conn;
        }
        catch(Exception e){
            JOptionPane.showMessageDialog(null,"MySql connection failed");

    }

我的Netbeans没有为我提供导入java.sql.connection的选项.我已经在库中添加了lib\mysql-connector-java-8.0.18.jar.此外，我还能够在Netbeans的服务"选项卡中查看我的所有数据库.我正在做一个Swing项目.谢谢！

My Netbeans is not giving me options to import the java.sql.connection. I have added the lib\mysql-connector-java-8.0.18.jar in my library. Additionally, I am also able to see all my databases in the services tab in Netbeans. I am working on a Swing project. Thank you!
