使用java代码向mysql数据库插入100万条数据

使用springboot集成Mysql数据库，并使用java代码循环向msql数据库插入100万条数据，并测试插入时间

一、使用工具

idea代码开发工具
mysq5.7.38
Navicat可视化工具

二、项目结构图

创建springboot项目启动类

MySpringBootApplication.java

package com.xiaoa;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MySpringBootApplication {

    public static void main(String[] args) {
        SpringApplication.run(MySpringBootApplication.class);
    }

}

创建插入数据类

MySchedulRunner.java,此类使用 JdbcTemplate 执行拼接的sql语句。

package com.xiaoa.run;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;

@Component
public class MySchedulRunner implements CommandLineRunner {
    private static final Logger LOGGER = LoggerFactory.getLogger(MySchedulRunner.class);

    @Autowired
    JdbcTemplate jdbcTemplate;

    @Override
    public void run(String... args) {

        /*
         *向数据库t_user表循环插入数据
         */
        String sql = "";
        long t1 = System.currentTimeMillis();
        int batchNum = 1000000;
        for (int i = 1; i <= batchNum; i++) {
            sql = "INSERT INTO t_user VALUES (" + i + ",'张三', 20, '男', '2019-01-01 00:00:01')";
            jdbcTemplate.execute(sql);
        }
        long t2 = System.currentTimeMillis();
        LOGGER.info("插入{}条数据，耗时{}秒", batchNum, (t2 - t1) / 1000);

    }

三、结论

数据成功插入到myql数据库中！

经过测试此代码成功将100万条数据插入到了mysql数据库，耗时2116秒，约1000000/2116=472条/秒，速度比手工插入还是快很多的！

四、表结构与建表语句

表结构

使用Navicat查看表结构

建表语句

CREATE TABLE `t_user`  (
  `id` int(11) NOT NULL,
  `name` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL,
  `age` int(11) NULL DEFAULT NULL,
  `sex` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL,
  `createtime` datetime(0) NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP(0),
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_bin ROW_FORMAT = Dynamic;

SET FOREIGN_KEY_CHECKS = 1;
