一、在pom中添加依赖

    <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.33</version>
        </dependency>
    </dependencies>

然后同步一下

二、编写代码

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

public class Test {
    public static void main(String[] args) {
        Connection connection = null;
        String url = "jdbc:mysql://localhost:3306/test";
        String user = "root";
        String password = "root";
        try {
            Class.forName("com.mysql.cj.jdbc.Driver");
            connection = DriverManager.getConnection(url, user, password);
        } catch (Exception e) {
            System.out.println("Exception." + e.getMessage());
        } finally {
            // Close the connection
            if (connection != null) {
                try {
                    System.out.println("Success to  connection.");
                    connection.close();
                } catch (SQLException e) {
                    System.out.println("Failed to close connection.");
                    e.printStackTrace();
                }
            } else {
                System.out.println("Failed to  connection.");
            }
        }
    }
}

这是我的数据库名
