RocketMQ环境搭建、环境测试、以及和SpringBoot整合代码演示_java

一、RocketMQ环境搭建 1、软件准备

RocketMQ最新版本：4.5.1
下载地址

2、环境要求

JDK1.8以上
Linux64位系统(CentOS Linux release 7.7.1908)
源码安装需要安装Maven 3.2.x
4G+ free (如果给不到虚拟机4G可用内存可以修改rocketma配置下面介绍)

3、安装及启动

下载rocketmq

 #下载
 wget https://archive.apache.org/dist/rocketmq/4.5.1/rocketmq-all-4.5.1-bin-release.zip

修改脚本

 bin/runserver.sh
 bin/runbroker.sh
 bin/tools.sh

vim runserver.sh
vim runbroker.sh
vim tools.sh

启动NameServer

 # 1.启动NameServer
 mqnamesrv
 # 2.查看启动日志
 tail -f ~/logs/rocketmqlogs/namesrv.log

启动Broker

 # 1.启动Broker
 mqbroker -n localhost:9876
 # 2.查看启动日志
 tail -f ~/logs/rocketmqlogs/broker.log

二、RocketMQ环境测试 1、发送消息

# 1.设置环境变量
export NAMESRV_ADDR=localhost:9876
# 2.使用安装包的Demo发送消息
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

2、接收消息

# 1.设置环境变量
export NAMESRV_ADDR=localhost:9876
# 2.接收消息
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

3、关闭RocketMQ

# 1.关闭NameServer
mqshutdown namesrv
# 2.关闭Broker
mqshutdown broker

三、RocketMQ和SpringBoot的整合 1、消息生产者

添加依赖

配置文件

 # rocketmq的nameserver地址
 rocketmq.name-server=IP:9876
 # 指定生产组名称
 rocketmq.producer.group=producer_grp

启动类

@SpringBootApplication
public class MQProducerApplication {
	public static void main(String[] args) {
		SpringApplication.run(MQSpringBootApplication.class);
	}
}

测试类

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {MyRocketProducerApplication.class})
public class MyRocketProducerApplicationTest {

    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    @Test
    public void testSendMessage() {
        // 用于向broker发送消息
        // 第一个参数是topic名称
        // 第二个参数是消息内容
        this.rocketMQTemplate.convertAndSend(
                "tp_springboot",
                "springboot: hello ckw"
        );
    }

    @Test
    public void testSendMessages() {
        for (int i = 0; i < 100; i++) {
            // 用于向broker发送消息
            // 第一个参数是topic名称
            // 第二个参数是消息内容
            this.rocketMQTemplate.convertAndSend(
                    "tp_springboot",
                    "springboot: hello ckw" + i
            );
        }
    }
}

2、消息消费者

消息监听器

@Slf4j
@Component
@RocketMQMessageListener(topic = "tp_springboot", consumerGroup = "consumer_grp")
public class MyRocketListener implements RocketMQListener<String> {
    @Override
    public void onMessage(String message) {
        // 处理broker推送过来的消息
        log.info(message);
    }
}
