RocketMQ快速应用

RocketMQ搭建链接:RockerMQ搭建

RocketMQ功能特性：

RocketMQ的介绍官网及网上一大堆，本文主要介绍应用场景，以及编写简单的代码样例

RocketMQ应用场景1：

我参与的上一个项目是一个网上电子税务系统，纳税人可以在网上通过此系统报税，简称系统a。纳税人还可以去税务厅通过排队纸质填表报税，税务厅使用的系统简称系统b。系统a和系统b所有的数据最终提交到系统c处理。系统c需要同事处理系统a和系统b的数据，如果是报税高峰期，系统c可能处理不过来。例如，李三通过系统a报税，填写了许多资料，花了大概半个小时，然后满意的点击了提交按钮，结果发现页面提示系统c繁忙，请刷新页面重新提交或者稍后提交。李三擦了擦汗，刷新了一下，发现还好之间填的数据系统有缓存还在，于是又点击了一次提交。然后页面还是提示系统c繁忙。于是他只能等到半夜人少的时候再来提交数据。
场景分析：报税高峰期，系统c由于并发量太大，会出现处理系统a和系统b的数据时间缓慢，导致用户重复提交，导致大量来自系统a和系统b的请求被积压，最后可能导致系统c瘫痪。
解决方案：我们公司负责系统a，于是我们在系统a使用了RocketMQ中间件，用户提交数据的时候，先发送提交的数据到RocketMQ，当系统c出现处理数据并发量过大（可以通过监控处理数据的时间等手段），系统a就减少提交到系统c的并发量数据。使用ROcketMQ之后，李三在报税高峰期提交数据，发现页面提示：“您提交的请求正在排队处理中，您可以关闭页面，数据提交成功后会以短信的形式发送给您！”李三看到提示开心的关掉了网页，过了一会手机收到税务局短信提示报税成功。

RocketMQ应用场景2：

张三在微信小程序买了一件商品，支付成功后系统需要从他的账户减去30元金额，商家的账号需要增加30元金额。这个过程涉及到了大量的数据验证系统交互，假设支付成功后系统给张三账户减去30元金额花费0.5秒，然后系统再给商家账户增加30元金额也需要花费0.5秒，那么整个过程就需要花费1秒。如果系统1秒内只能处理10000个用户的请求，那么第10001个用户的请求就会被拒绝。使用RocketMQ将购买商品支付账户操作拆分为两个过程，过程一：“张三账户减30元，将这个消息发送到RocketMQ，数据库减去30元后不再管商家是否账户已经收到30元”，过程二：：”系统消费RocketMQ的消息,进行商家账户加30元的操作“。这样让两个过程并行运行，系统处理整个过程就变成了0.5秒，提高了吞吐量。使用RocketMQ是基于它的可靠性，就是说整个过程中消息发送成功率为%99.9，剩下的很小的错误概率可以通过日记等记录人工处理。

第一步：项目导入RoketMQ的包

        <dependency>
            <groupId>commons-collections</groupId>
            <artifactId>commons-collections</artifactId>
            <version>3.2.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-client</artifactId>
            <version>4.3.0</version>
        </dependency>

代码：

public static void main(String [] args) throws MQClientException, RemotingException, InterruptedException, MQBrokerException {
        DefaultMQProducer producer = new DefaultMQProducer("test_quick_producer_name");
        //端口号一般是使用9876，Const.NAMESRV_ADDR=106.13.88.XXX:19876
        producer.setNamesrvAddr(Const.NAMESRV_ADDR);
        producer.start();
        for(int i = 0; i <6; ++i ){
            Message message = new Message("topic_quick_test",
                    "tag_quick_test","key"+i,("hello quick_start!"+i).getBytes());
           SendResult sendResult =  producer.send(message);
           System.out.println("发送的消息为:"+sendResult);
        }
        //消息发完了得关闭
        producer.shutdown();
    }

控制台打印消息为：

queueId表示消息使用第几个队列发送，默认为4个队列
