JDBC无法连接到数据库[重复]

我编写了一些代码来在本地数据库中插入一个表,每次堆栈跟踪都会出现以下错误:

java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

显然,我可能错了,但这与我的时区或mysql或jdbc连接器中设置时区的方式有关。

这是我的原始源代码:

import com.mysql.jdbc.Driver;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class CreateTable {
    public static void main(String[] args) throws SQLException {
        Connection myConnection = null;
        Statement myStmt = null;
        //ResultSet rs = null;
        String sql = "create table student(student_id varchar(20) primary key, name varchar(30), class varchar(15), marks varchar(10);";

        try {
        /*
        Get Connection to jdbc
        */
        myConnection = DriverManager.getConnection("jdbc:mysql://localhost:3306/edureka?autoReconnect=true&useSSL=false", "userOne", "password");

        /*Create an object for passing SQL queries to DB */
        myStmt = myConnection.createStatement();

        /*Execute a resulting statement to create a table in the DB */
        myStmt.executeQuery(sql);

        System.out.println("DB Table created in Database Edureka!");

        } catch(Exception e) {
            e.printStackTrace();
        }

    }
}
