Main.java的內容：

package cn.liuxingchang;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;

public class Main {
    public static void main(String[] args) {
        //1、準備資料來源：這裡使用Spring內建的資料來源
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        //2、設定資料庫的相關屬性
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        String url = "jdbc:mysql://localhost:3306/test?characterEncoding=UTF8&serverTimezone=Asia/Shanghai";
        dataSource.setUrl(url);
        dataSource.setUsername("root");
        dataSource.setPassword("123456");

        //3、新建JdbcTemplate，並繫結資料來源
        JdbcTemplate template = new JdbcTemplate(dataSource);

        //4、進行CRUD操作
        template.execute("update account set money = 400 where id = 4");
    }
}
