idea中如何使用mysql数据库

CREATE DATABASE mydatabase;
USE mydatabase;

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50),
    email VARCHAR(50)
);

spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=root
spring.datasource.password=your_password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.27</version>

import java.sql.*;

public class MySQLExample {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "your_password";

        try (Connection connection = DriverManager.getConnection(url, username, password);
             Statement statement = connection.createStatement()) {

            String query = "SELECT * FROM users";
            ResultSet resultSet = statement.executeQuery(query);

            while (resultSet.next()) {
                int id = resultSet.getInt("id");
                String name = resultSet.getString("name");
                String email = resultSet.getString("email");
                System.out.println("ID: " + id + ", Name: " + name + ", Email: " + email);
            }

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