RocketMQ在windows上安装和开发使用
来源:互联网 发布:mac怎么装虚拟机win10 编辑:程序博客网 时间:2024/06/06 00:23
1.概述
RocketMQ是alibaba公司开源的一个纯java的开源消息中间件。
文档:http://rocketmq.apache.org/docs/quick-start/
2.开发测试环境搭建
1. 安装&启动
进入到RocketMQ下载包解压的路径下
D:\machine\RocketMQ-3.0.8\RocketMQ-3.0.8>
接下来安装
执行下边的命令或者执行install.bat(在这个bat文件中的命令如下)对maven熟悉的一眼就知道是执行clean package install assembly等操作。
mvn -Dmaven.test.skip=true clean packageinstall assembly:assembly –U
操作信息如下:
接下来把编译好的项目copy出来 RocketMQ-3.5.8\target\alibaba-rocketmq-broker\alibaba-rocketmq
启动服务
//启动mqnamesrv
可以通过jps查看一下是不是有了RocketMQ的进程,如下方的6484
看日志中信息D:\logs\alibaba-rocketmq/mqnamesrv.log
The Name Server boot success.
//启动broker
看日志中信息D:\logs\alibaba-rocketmq/mqbroker.log
The broker[houchangren, 10.57.41.19:10911]boot success.
2.2 解压缩,并进入bin目录
2.3 启动name server
打击mqnamesrv.exe,启动name server,保持mqnamesrv.exe运行,不要关闭这个终端。
2.4 启动broker
方法一:开启另一个windows终端cmd,进入解压的bin目录,先输入set NAMESRV_ADDR=127.0.0.1:9876
设置环境变量,输入mqbroker.exe
启动broker,保持mqbroker.exe运行,不要关闭这个终端。
方法二:开启另一个windows终端cmd,进入解压的bin目录,也可一步输入mqbroker -n 127.0.0.1:9876
启动broker,保持mqbroker.exe运行,不要关闭这个终端。
2.项目实例
1. 创建maven项目
Pom.xml文件如下
2. 编写消息产生者Producer
文件路径:/gomeTest/src/main/java/com/ruishenh/rocketmq/example/Producer.java
package com.ruishenh.rocketmq.example;
import java.util.concurrent.TimeUnit;import com.alibaba.rocketmq.client.exception.MQClientException;import com.alibaba.rocketmq.client.producer.DefaultMQProducer;import com.alibaba.rocketmq.client.producer.SendResult;import com.alibaba.rocketmq.common.message.Message;public class Producer { public static void main(String[] args) throws MQClientException, InterruptedException { /** * 一个应用创建一个Producer,由应用来维护此对象,可以设置为全局对象或者单例<br> * 注意:ProducerGroupName需要由应用来保证唯一<br> * ProducerGroup这个概念发送普通的消息时,作用不大,但是发送分布式事务消息时,比较关键, * 因为服务器会回查这个Group下的任意一个Producer */ final DefaultMQProducer producer = new DefaultMQProducer("ProducerGroupName"); producer.setNamesrvAddr("127.0.0.1:9876"); producer.setInstanceName("Producer"); /** * Producer对象在使用之前必须要调用start初始化,初始化一次即可<br> * 注意:切记不可以在每次发送消息时,都调用start方法 */ producer.start(); /** * 下面这段代码表明一个Producer对象可以发送多个topic,多个tag的消息。 * 注意:send方法是同步调用,只要不抛异常就标识成功。但是发送成功也可会有多种状态,<br> * 例如消息写入Master成功,但是Slave不成功,这种情况消息属于成功,但是对于个别应用如果对消息可靠性要求极高,<br> * 需要对这种情况做处理。另外,消息可能会存在发送失败的情况,失败重试由应用来处理。 */ for (int i = 0; i < 10; i++) { try { { Message msg = new Message("TopicTest1",// topic "TagA",// tag "OrderID001",// key ("Hello MetaQA").getBytes());// body SendResult sendResult = producer.send(msg); System.out.println(sendResult); } { Message msg = new Message("TopicTest2",// topic "TagB",// tag "OrderID0034",// key ("Hello MetaQB").getBytes());// body SendResult sendResult = producer.send(msg); System.out.println(sendResult); } { Message msg = new Message("TopicTest3",// topic "TagC",// tag "OrderID061",// key ("Hello MetaQC").getBytes());// body SendResult sendResult = producer.send(msg); System.out.println(sendResult); } } catch (Exception e) { e.printStackTrace(); } TimeUnit.MILLISECONDS.sleep(1000); } /** * 应用退出时,要调用shutdown来清理资源,关闭网络连接,从MetaQ服务器上注销自己 * 注意:我们建议应用在JBOSS、Tomcat等容器的退出钩子里调用shutdown方法 */ // producer.shutdown(); Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() { public void run() { producer.shutdown(); } })); System.exit(0); }}
3. 编写消息消费者Consumer
文件路径:Test/src/main/java/com/ruishenh/rocketmq/example/PushConsumer.java
package com.ruishenh.rocketmq.example;
import com.alibaba.rocketmq.client.consumer.DefaultMQPushConsumer;import com.alibaba.rocketmq.client.consumer.listener.ConsumeConcurrentlyContext;import com.alibaba.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus;import com.alibaba.rocketmq.client.consumer.listener.MessageListenerConcurrently;import com.alibaba.rocketmq.client.exception.MQClientException;import com.alibaba.rocketmq.common.message.MessageExt;import java.util.List;public class PushConsumer { /** * 当前例子是PushConsumer用法,使用方式给用户感觉是消息从RocketMQ服务器推到了应用客户端。<br> * 但是实际PushConsumer内部是使用长轮询Pull方式从MetaQ服务器拉消息,然后再回调用户Listener方法<br> */ public static void main(String[] args) throws InterruptedException, MQClientException { /** * 一个应用创建一个Consumer,由应用来维护此对象,可以设置为全局对象或者单例<br> * 注意:ConsumerGroupName需要由应用来保证唯一 */ DefaultMQPushConsumer consumer = new DefaultMQPushConsumer( "ConsumerGroupName"); consumer.setNamesrvAddr("127.0.0.1:9876"); consumer.setInstanceName("Consumber"); /** * 订阅指定topic下tags分别等于TagA或TagC或TagD */ consumer.subscribe("TopicTest1", "TagA || TagC || TagD"); /** * 订阅指定topic下所有消息<br> * 注意:一个consumer对象可以订阅多个topic */ consumer.subscribe("TopicTest2", "*"); consumer.registerMessageListener(new MessageListenerConcurrently() { public ConsumeConcurrentlyStatus consumeMessage( List<MessageExt> msgs, ConsumeConcurrentlyContext context) { System.out.println(Thread.currentThread().getName() + " Receive New Messages: " + msgs.size()); MessageExt msg = msgs.get(0); if (msg.getTopic().equals("TopicTest1")) { //执行TopicTest1的消费逻辑 if (msg.getTags() != null && msg.getTags().equals("TagA")) { //执行TagA的消费 System.out.println(new String(msg.getBody())); } else if (msg.getTags() != null && msg.getTags().equals("TagC")) { //执行TagC的消费 System.out.println(new String(msg.getBody())); } else if (msg.getTags() != null && msg.getTags().equals("TagD")) { //执行TagD的消费 System.out.println(new String(msg.getBody())); } } else if (msg.getTopic().equals("TopicTest2")) { System.out.println(new String(msg.getBody())); } return ConsumeConcurrentlyStatus.CONSUME_SUCCESS; } }); /** * Consumer对象在使用之前必须要调用start初始化,初始化一次即可<br> */ consumer.start(); System.out.println("ConsumerStarted."); }}
