RocketMQ安装步骤略。

开启rocketmq:

windows

start mqnamesrv.cmd
    
    start mqbroker.cmd -n 127.0.0.1:9876 autoCreateTopicEnable=true

### 一、RocketMQ可视化界面安装 ###

下载

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBARHJhZ29uICAgV3U_size_20_color_FFFFFF_t_70_g_se_x_16][]

下载好以后，修改配置文件：

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBARHJhZ29uICAgV3U_size_18_color_FFFFFF_t_70_g_se_x_16][]

打包：

mvn clean package -Dmaven.test.skip=true

进入 target 启动 jar：

java -jar rocketmq-console-ng-1.0.0.jar

成功开启后，运行可视化项目，一般第一次运行会添加很多maven依赖

运行后服务可视化界面：

### 二、springcloudstream整合rocketmq ###

#### 1、引入依赖 ####

使用时记得对应自己的版本

<dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-stream-rocketmq</artifactId>
            </dependency>

#### 2、开启输入何输出 ####

@EnableBinding

package com.wxl;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.stream.annotation.EnableBinding;
    import org.springframework.cloud.stream.messaging.Sink;
    import org.springframework.cloud.stream.messaging.Source;
    
    
    @EnableBinding({Source.class, Sink.class})
    @SpringBootApplication
    public class ConsumerApplication {
        public static void main(String[] args) {
            SpringApplication.run(ConsumerApplication.class,args);
        }
    }

#### 3、关键的一步，配置文件 ####

spring:
      cloud:
        stream:
          bindings:
            input:  # 对应消费者
              destination: TestTopic
              group: scGroup
            output:  # 对应生产者
              destination: TestTopic
    
          rocketmq:
            binder:
              name-server: 127.0.0.1:9876

#### 4、主类 ####

#### 5、控制器 ####

package com.wxl.controller;
    
    import com.wxl.basic.ScProducer;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import javax.annotation.Resource;
    
    @RestController
    @RequestMapping("/MQTest")
    public class MQTestController {
        @Resource
        private ScProducer producer;
    
        @RequestMapping("/sendMessage")
        public String sendMessage(String message) {
            producer.sendMessage(message);
            return "消息发送完成";
        }
    }

#### 6、消息消费者 ####

package com.wxl.basic;
    
    import org.springframework.cloud.stream.annotation.StreamListener;
    import org.springframework.cloud.stream.messaging.Sink;
    import org.springframework.stereotype.Component;
    
    @Component
    public class ScConsumer {
        @StreamListener(value = Sink.INPUT)
        public void onMessage(String message) {
            System.out.println("received message:" + message + "from binding:" + Sink.INPUT);
        }
    }

#### 7、消息生产者 ####

package com.wxl.basic;
    
    import org.apache.rocketmq.common.message.MessageConst;
    import org.springframework.cloud.stream.messaging.Source;
    import org.springframework.messaging.Message;
    import org.springframework.messaging.MessageHeaders;
    import org.springframework.messaging.support.MessageBuilder;
    import org.springframework.stereotype.Component;
    
    import javax.annotation.Resource;
    import java.util.HashMap;
    import java.util.Map;
    
    @Component
    public class ScProducer {
        @Resource
        private Source source;
    
        public void sendMessage(String msg){
            Map<String,Object> headers=new HashMap<String,Object>();
            headers.put(MessageConst.PROPERTY_TAGS,"testTag");
            MessageHeaders messageHeaders=new MessageHeaders(headers);
            Message<String> message= MessageBuilder.createMessage(msg,messageHeaders);
            this.source.output().send(message);
        }
    
    }
