MYSQL插入千万数据的工具类

建表语句

CREATE TABLE `test_id`  (
  `id` int(10) NOT NULL AUTO_INCREMENT COMMENT '主键自增非空',
  `name` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `age` int(3) NULL DEFAULT NULL,
  `address` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `birthday` datetime(0) NULL DEFAULT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 11000010 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;

        String[] city1 = {"西安市", "延安市", "铜川市", "渭南市", "咸阳市", "宝鸡市", "汉中市", "榆林市", "安康市", "商洛市"};
        LocalDateTime begin = LocalDateTime.now();
        for (int i = 0; i < 100; i++) {
            StringBuilder sb = new StringBuilder(" insert into test_id(name, age, address, birthday) values ");

            for (int j = 0; j < 100000; j++) {
                sb.append(" ('").append(NameUtil.getRandomUserName()).append("', ").append(i).append(", '").append(city1[i % city1.length]).append("', '2019-").append(i % 12 + 1).append("-").append(j % 27 + 1).append("'),");
            }
            String sql = sb.toString().substring(0, sb.length() - 1);
            Statement statement = conn.createStatement();
            statement.execute(sql);
        }
        LocalDateTime end = LocalDateTime.now();
        Duration between = Duration.between(begin, end);
