发现此错误“没有找到适合 jdbc:mysql//localhost:3306/student 的驱动程序”

Question

I was try to create simple java student GUI app in IntelliJ IDEA and its working fine. Then I just try to connect database to inset all data into MYSQL, so I create Schema( student ) and Table( appointment ) in MySQL Workbatch and then connect that database in IntelliJ IDEA Database window you can see in the picture and its successfully configured it.

Now I try to create connection via below line.

Connection con = DriverManager.getConnection("jdbc:mysql//localhost:3306/student","root","root");

But this line give me this error Error: No suitable driver found for jdbc:mysql//localhost:3306/student

So I google it and I found this line.

Class.forName("com.mysql.cj.jdbc.Driver");

but this line give this error Error: com.mysql.cj.jdbc.Driver

Please everyone have a look in it, Its very helpful to me and other one who face this issue.

Answer 1

 private DBconnectionSingleton() throws SQLException {
    // create single instance of DB connection 
    Properties connectionProps = new Properties();
    connectionProps.put("user", login);
    connectionProps.put("password", password);// port & db name
    System.out.println("Loading driver...");


    try {
        Class.forName("com.mysql.cj.jdbc.Driver");
        System.out.println("Driver loaded!");
    } catch (ClassNotFoundException e) {
        throw new IllegalStateException("Cannot find the driver in the classpath!", e);
    }

    conn = DriverManager.getConnection(
            "jdbc:mysql://localhost:3306/student",
            connectionProps
    );
}
