How to install the MySQL driver

1. Download the MySQL driver

Before installing the MySQL driver, you first need to download it from the MySQL official website (https://dev.mysql.com/downloads/connector/j/ ) to download the driver that suits you. Currently, MySQL provides multiple versions of drivers, including MySQL Connector/J, MySQL Connector/ODBC, MySQL Connector/C, etc. In the Connector/J column of the MySQL official website download page, find the latest MySQL Connector/J version and click "Download" to download.

2. Install the MySQL driver

After the download is completed, unzip the MySQL Connector/J compressed package and copy the .jar file to the appropriate location , in order to use the MySQL driver in a Java program.

In Java development environments such as Eclipse, you can add the MySQL driver to the "Build Path" of the project, so that the MySQL driver can be used in Java programs.

When using the MySQL driver, you need to load the MySQL driver in the Java program. This can be achieved by using the Class.forName() method. The following is a Java code sample using the MySQL driver:

try {
    // 加载MySQL驱动程序
    Class.forName("com.mysql.jdbc.Driver");

    // 建立与MySQL服务器的连接
    String url = "jdbc:mysql://localhost:3306/mydatabase";
    String user = "root";
    String password = "mypassword";
    Connection conn = DriverManager.getConnection(url, user, password);

    // 执行SQL语句
    Statement stmt = conn.createStatement();
    ResultSet rs = stmt.executeQuery("SELECT * FROM mytable");
    while (rs.next()) {
        System.out.println(rs.getString("fieldname"));
    }

    // 关闭连接
    rs.close();
    stmt.close();
    conn.close();

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

In the above code, use Class.forName("com.mysql.jdbc.Driver") to load the MySQL driver and use DriverManager.getConnection () method establishes a connection to the MySQL server. You can use Statement objects to execute SQL statements and retrieve query results from ResultSet objects.
