Redis进阶例子

Posted 2021-11-30 timesay

工作中用到的RabbitMQ例子 , 但是最后没有用 , 用的CMQ , 顺便说下CMQ社区真的少 , 并且功能少 .

一、消息体

package com.bootdo.common.rabbitmq.batchsendsms;

import com.alibaba.fastjson.JSON;
import com.bootdo.common.utils.UUIDGenerator;

import java.io.Serializable;
import java.util.Date;

public class BacthSendSMSMessage implements Serializable{

    private Integer intRun;//当前次数
    private Integer total;//总次数
    private String productCode; // 生产者代码
    private String consumerCode; // 消费者代码
    private String messageId; // 消息唯一标识
    private Date created; // 消息发送时间
    private Map<String, Object> bussinessBody; // 消息体，封装业务数据

    public String getProductCode() {

    public Map<String, Object> getBussinessBody() {
        return bussinessBody;
    }

    public void setBussinessBody(Map<String, Object> bussinessBody) {

    }

    public static long getSerialVersionUID() {
        return serialVersionUID;
    }

    public Integer getIntRun() {
        return intRun;
    }

    public void setIntRun(Integer intRun) {
        this.intRun = intRun;
    }

    public Integer getTotal() {
        return total;
    }

    public void setTotal(Integer total) {
        this.total = total;
    }

    @Override
    public String toString() {
        return "BacthSendSMSMessage{" +
                "intRun=" + intRun +

 如果实际用需要优化 ， 我这个没有优化就被砍掉啦 ， 很遗憾 等下次用到再更新，确认回调机制 用redis做就可以。

　　如果有疑问或者建议欢迎评论。
