如何解决 java.sql.SQLException: 在数据库与 JDBC API 的集成中？

代码片段：

package dbIntegrationwithJDBC;

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

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Example1 {
    public static void main(String[] args) throws SQLException, InterruptedException {
        String host = "localhost";
        String port = "3306";

        Connection con = DriverManager.getConnection("jdbc:mysql://" + host + ":" + port + "/mastro1729", "root",
                "mysql123");
        Statement s = con.createStatement();
        ResultSet rs = s.executeQuery("select*from credentials where Scenario='mastro1729'");
        System.out.println(rs.getString("Username"));
        System.out.println(rs.getString("Password"));

        while (rs.next()) {

            WebDriver driver = new ChromeDriver();
            driver.get("https://login.salesforce.com");

            driver.findElement(By.name("usernameOrEmail")).sendKeys(rs.getString("Username"));
            driver.findElement(By.xpath("//button[text()='Continue']")).click();
            Thread.sleep(3000);

            driver.findElement(By.name("password")).sendKeys(rs.getString("Password"));
            driver.findElement(By.xpath("//button[text()='Log In']")).click();
            Thread.sleep(3000);

        }
    }
}

错误信息：

Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/mastro1729
    at java.sql.DriverManager.getConnection(Unknown Source)
    at java.sql.DriverManager.getConnection(Unknown Source)
    at dbIntegrationwithJDBC.Example1.main(Example1.java:23)

我正在尝试使用 JDBC API 连接到 MySQL 数据库。我在本地主机上用 mastro1729 创建了 MySQL 数据库。我的代码似乎是正确的，并且我已将 mysql-connector-java.jar 文件添加到 eclipse。当我尝试将我的数据库与 JDBC API 集成时，我收到了java.sql.SQLException at DriverManager.getConnection();声明。我已经尽力了，但我无法解决问题。

我究竟做错了什么？
