现在是2020年1月19日 我的docker都不是最新版的

一、部署RocketMq

先创建好几个文件夹，用来放日志和配置：

mkdir /usr/local/docker/rocketmq
cd /usr/local/docker/rocketmq
mkdir data
cd data
mkdir logs
mkdir store
mkdir brokerconf
cd brokerconf
vi broker.conf

其中 broker.conf内容如下：

brokerClusterName=DefaultCluster
brokerName=broker-a
brokerId=0
# 修改为你宿主机的 IP
brokerIP1=192.168.30.131
defaultTopicQueueNums=4
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
listenPort=10911
deleteWhen=04
fileReservedTime=120
mapedFileSizeCommitLog=1073741824
mapedFileSizeConsumeQueue=300000
diskMaxUsedSpaceRatio=88
maxMessageSize=65536
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH

创建docker-compose.yml

cd /usr/local/docker/rocketmq
vi docker-compose.yml的内容如下：

version: '3.5'
services:
  rmqnamesrv:
    image: foxiswho/rocketmq:server
    container_name: rmqnamesrv
    ports:
      - 9876:9876
    volumes:
      - ./data/logs:/opt/logs
      - ./data/store:/opt/store
    networks:
        rmq:
          aliases:
            - rmqnamesrv
  rmqbroker:
    image: foxiswho/rocketmq:broker
    container_name: rmqbroker
    ports:
      - 10909:10909
      - 10911:10911
    volumes:
      - ./data/logs:/opt/logs
      - ./data/store:/opt/store
      - ./data/brokerconf/broker.conf:/etc/rocketmq/broker.conf
    environment:
        NAMESRV_ADDR: "rmqnamesrv:9876"
        JAVA_OPTS: " -Duser.home=/opt"
        JAVA_OPT_EXT: "-server -Xms128m -Xmx128m -Xmn128m"
    command: mqbroker -c /etc/rocketmq/broker.conf
    depends_on:
      - rmqnamesrv
    networks:
      rmq:
        aliases:
          - rmqbroker
  rmqconsole:
    image: styletang/rocketmq-console-ng
    container_name: rmqconsole
    ports:
      - 8080:8080
    environment:
        JAVA_OPTS: "-Drocketmq.namesrv.addr=rmqnamesrv:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false"
    depends_on:
      - rmqnamesrv
    networks:
      rmq:
        aliases:
          - rmqconsole
networks:
  rmq:
    name: rmq
    driver: bridge

PS:
1、rocketmq:serverMQ的服务
2、rocketmq:brokerMq的中间件
3、rocketmq-console-ngMq的可视化控制台
运行：docker-compose up

二、Spring Boot Demo 之生产者

参考资料spring-cloud-alibaba：https://github.com/alibaba/spring-cloud-alibaba/wiki/RocketMQ-en
这里我们简单的创建一个spring boot demo来调用它。
项目源码：https://github.com/xcocean/rocketmq-demo
pom.xml加入，此时需要注意，spring boot使用的版本是2.1.10（2020年1月20日 最新版），如果使用2.2.x会报错，他们的特性不一样了。

        <!-- RocketMQ 依赖 -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-stream-rocketmq</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

application.yml

spring:
  jackson:
    time-zone: GMT+8
    date-format: yyyy-MM-dd HH:mm:ss
  cloud:
    # RocketMQ 相关配置
    stream:
      rocketmq:
        binder:
          name-server: 192.168.75.129:9876
      bindings:
        #自定义的名称 # test-group(一级分类)
        test-group: {destination: test-group,content-type: application/json}

创建MyProduce

import org.springframework.cloud.stream.annotation.Output;
import org.springframework.messaging.MessageChannel;

public interface MyProduce {

    @Output("test-group")
    MessageChannel log();
}

在应用启动入口绑定上面的MyProduce.java

import com.lingkang.rocketmqdemo.mq.MyProduce;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.stream.annotation.EnableBinding;

@SpringBootApplication
@EnableBinding({MyProduce.class})
public class RocketmqDemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(RocketmqDemoApplication.class, args);
    }
}

controller中直接装配即可

import com.lingkang.rocketmqdemo.mq.MyProduce;
import org.apache.rocketmq.spring.support.RocketMQHeaders;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author linke
 * @date 2020-01-19 下午 21:08
 * @description
 */
@RestController
public class MainController {

    @Autowired
    private MyProduce myProduce;

    @GetMapping("send")
    public Object send(String msg) throws Exception {
        myProduce.log().send(MessageBuilder.withPayload(msg).build());
        return "";
    }

    @GetMapping("send1")
    public Object send1(String msg) {
        //带上标签发送
        MessageBuilder builder = MessageBuilder.withPayload(msg)
                .setHeader(RocketMQHeaders.TAGS, "log")
                .setHeader(RocketMQHeaders.KEYS, "my-key")
                .setHeader("DELAY", "1");
        Message message = builder.build();
        myProduce.log().send(message);
        return message;
    }
}

访问http://localhost:8080/send?msg=%E4%BD%A0%E5%A5%BD11111111
和http://localhost:8080/send1?msg=%E4%BD%A0%E5%A5%BD11111111

三、Spring Boot Demo 之消费者

基于上面的项目
改动application.yml 添加消费者绑定

spring:
  jackson:
    time-zone: GMT+8
    date-format: yyyy-MM-dd HH:mm:ss
  cloud:
    # RocketMQ 相关配置
    stream:
      rocketmq:
        binder:
          name-server: 192.168.75.129:9876
      bindings:
        #自定义的名称 # test-group(一级分类)
        test-group: {destination: test-group,content-type: application/json}
        # consumer.maxAttempts
        # 消息最大可以被尝试消费的次数，包含第一次投递
        # 设为 1，表示不重试，注意该值必须大于 0
        input-consumer: {destination: test-group, content-type: text/plain,
                         group: test-group, consumer.maxAttempts: 1}

创建MyConsumer

public interface MyConsumer {
    @Input("input-consumer")
    MessageChannel log();
}

创建接收监听MyConsumerReceive

@Component
public class MyConsumerReceive {

    @StreamListener("input-consumer")
    public void receiveConsumer(Object msg) {
        System.out.println("消息消费：" + msg);
    }
}

结果如下：
