1、批量规则生成代码

1、随机IP生成代码
2、指定时间范围内随机日期生成代码
3、随机中文名生成代码。

package com.wfg.flink.connector.utils;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Random;

/**
 * @author wfg
 */
public class RandomGeneratorUtils {
    /**
     * 生成随机的IP地址
     * @return ip
     */
    public static String generateRandomIp() {
        Random random = new Random();

        // 生成IP地址的四个部分 0-255
        int part1 = random.nextInt(256);
        int part2 = random.nextInt(256);
        int part3 = random.nextInt(256);
        int part4 = random.nextInt(256);

        // 将每个部分转换为字符串，并用点连接
        return part1 + "." + part2 + "." + part3 + "." + part4;
    }
    /**

     *
     * @param startDate 开始日期
     * @param endDate 结束日期
     * @return 随机生成的日期时间
     */
    public static LocalDateTime generateRandomDateTime(LocalDate startDate, LocalDate endDate) {

        long startEpochDay = startDate.toEpochDay();
        long endEpochDay = endDate.toEpochDay();
        Random random = new Random();

            randomDate = LocalDate.ofEpochDay(randomDay);
        }

        LocalTime randomTime = LocalTime.of(
                // 小时
                random.nextInt(24),
                // 分钟
                random.nextInt(60),
                // 秒
                random.nextInt(60)
        );

        return LocalDateTime.of(randomDate, randomTime);
    }


    private static final List<String> FIRST_NAMES = new ArrayList<>();
    private static final List<String> LAST_NAMES = new ArrayList<>();

    static {
        // 初始化一些常见的名字和姓氏
        FIRST_NAMES.addAll(Arrays.asList("王","李","赵","刘","张", "钱", "孙", "周", "吴", "郑", "王", "冯", "陈", "褚", "卫", "蒋", "沈", "韩", "杨", "朱", "秦", "尤", "许", "何", "吕", "施",

                "鲁","韦", "昌", "马", "苗", "凤", " 刚", "文", "张", "桂", "富", "生", "龙", "功", "夫", "周", "建", "余", "冲", "程", "沙", "阳", "江", "潘"));

        LAST_NAMES.addAll(Arrays.asList("伟","芳","丽","强","明","风","阳","海","天","藏","霞","刚", "夫", "勇", "毅", "俊", "峰", "强", "军", "平", "保", "东", "文", "辉", "力", "明", "永", "健", "世", "广", "志", "义",

    }
    /**

    public static String generateRandomFullName() {

        String lastName = LAST_NAMES.get(random.nextInt(LAST_NAMES.size()));
        return firstName + lastName;
    }
}

2. 生成对象体

package com.wfg.flink.connector.dto;

import lombok.Data;

/**
 * @author wfg
 */
@Data
public class KafkaPvDto {
    // uuid
    private String uuid;
    // 用户名
    private String userName;
    // 访问时间
    private String visitTime;
    // 访问地址
    private String visitIp;
    // 访问服务IP
    private String visitServiceIp;
}

3. 批量数据生成推送代码

public class KafkaTestProducer {
    public static void main(String[] args) {
        Properties props = new Properties();
        props.put("bootstrap.servers", KAFKA_BROKERS);
        props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        try (Producer<String, String> producer = new KafkaProducer<>(props)){
            int times = 100000;
            for (int i = 0; i < times; i++) {
                System.out.println("Send No. :" + i );
                CompletableFuture.allOf(
