SpringCloud框架集成zookeeper集群+kafka集群

1.创建父子级项目结构，生产者springboot微服务与消费者springboot微服务。

2.生产者创建一个供与测试的实体Bean

package com.jk.bean;

import java.util.Date;

public class MessageBean {

    private Long id;    //id
    private String msg; //消息
    private Date sendTime;  //时间戳

    @Override
    public String toString() {
        return "MessageBean{" +
                "id=" + id +
                ", msg='" + msg + '\'' +
                ", sendTime=" + sendTime +
                '}';
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public Date getSendTime() {
        return sendTime;
    }

    public void setSendTime(Date
