JDBC之批量向MySQL中添加测试数据

package com.zkdx.hangul_service.test;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;

public class Test {
    public static void main(String[] args) throws Exception {
        Class.forName("com.mysql.cj.jdbc.Driver");
        String url = "jdbc:mysql://localhost:3306/test?useSSL=false&characterEncoding=UTF-8&serverTimezone=GMT";
        String user = "root";
        String password = "123456abc";
        Connection connection = DriverManager.getConnection(url, user, password);
        for (int i = 10; i < 300; i++) {
            String sql = "insert into jc_my_content(content_id,title,content,ImagePath) values(?,?,?,?)";
            PreparedStatement preparedStatement = connection.prepareStatement(sql);
            preparedStatement.setInt(1, i);
            preparedStatement.setString(2, i + "");

            int row = preparedStatement.executeUpdate();
        }
