Я пытаюсь подключить свой проект intelliJ java к mysql в первый раз, и, к сожалению, я получаю эту ошибку:
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

Я уже добавил MySQL-коннектор.вот мой простой код:
public static Connection getConnect (){
Connection connection = null;
try {
Class.forName("com.mysql.cj.jdbc.Driver");
connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/test" , "root" , "12345");
} catch (Exception e){
e.printStackTrace();
}
return connection;
}
