2. RocketMQ desktop management plug-in installation and deployment

2.1 Download address: https://github.com/apache/rocketmq-externals.git

Use github to clone the project in the address;

Deployment premise: java environment, maven environment needs to be available

2.2 Deploy the plugin

2.2.1: Enter the'rocketmq-externals\rocketmq-console\src\main\resources' folder and modify the startup configuration file application.properties;

Start the plug-in port number: server.port=8089 , this can be set randomly, as long as there is no conflict with the port of the existing service in the windows environment

The connection address of rocketmq : rocketmq.config.namesrvAddr=127.0.0.1:9876

2.2.2: Compile and start the project: enter the'\rocketmq-externals\rocketmq-console' folder, execute ' mvn clean package -Dmaven.test.skip=true' to compile and generate a jar package;

After successful compilation, Cmd enters the'target' folder, executes'java -jar rocketmq-console-ng-1.0.0.jar', and starts " rocketmq-console-ng-1.0.0.jar "

After successful installation and deployment, visit: localhost:8089, you will see the following interface

Three. Springboot integrates the basic functions of RocketMQ

3.1 Create a springboot project and add the pom dependency of rocketmq

<dependency>
     <groupId>org.apache.rocketmq</groupId>
     <artifactId>rocketmq-spring-boot-starter</artifactId>
     <version>2.1.0</version>
</dependency>

3.2 configure yml file

rocketmq:
  name-server: 127.0.0.1:9876
  producer:
    group: my-producer-group

3.3 Create Producer Producer

package com.demo.rocketmq.simpleTest;

import io.swagger.annotations.Api;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Api
@RequestMapping("/test")
@RestController
public class Producer {
    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    @GetMapping("send")
    public void send(){
        rocketMQTemplate.convertAndSend("test-topic","你好,Java旅途");
    }

}

3.4 Create Consumer

package com.demo.rocketmq.simpleTest;

import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;

@Slf4j
@Component
@RocketMQMessageListener(topic = "test-topic",consumerGroup = "my-consumer-group")
public class Consumer implements RocketMQListener<String> {
    @Override
    public void onMessage(String message) {
        log.info("我收到消息了！消息内容为："+message);
    }
}

3.5 Starting the project

3.5.1: You need to configure topic before startup: you can add it on the management console page

3.5.2: Visit address: http:/127.0.0.1/test/send, you can see the log generated by the project console.

3.6: Testing

Use jemeter to test the effect: Of course, you can also use postman to test: I am used to test what will happen with high concurrency;

Configure the number of threads:

Configure url:

Check the performance consumption of the computer: As can be seen from the figure below, the CPU utilization has reached 100%, and the memory has reached 12G, and it lasts for a long time. It has been processing the request, and it will be processed after a while .

The above is the simple integration steps of rocketmq installation and deployment. This is only the simplest integration step. The actual use is far more than this. Interested students can learn about the method of RocketMQ packaging.

Follow-up bloggers will also supplement the use of related RocketMQ packages, and everyone will learn and make progress together.
