记录spring-boot 3.X版本整合RocketMq

版本信息

先把该次整合的版本信息列如下：

spring-boot

spring-cloud

rocketmq-spring-boot-starter

rocketmq-client

rocketmq

3.0.13

2022.0.5

2.2.3

4.9.8

4.9.8

版本信息是如何选择的呢？看rocketMq官网springcloud alibaba版本声明

rocketMq我用的是最新的4.X版本4.9.8

本地启动rocketMq服务端

这块你们找文章看。我是从github上fork后下载到本地。使用idea启动nameSrv和broker

构建测试工程

先创建父工程，用于pom的依赖继承

配置属性

    <maven.compiler.source>17</maven.compiler.source>
    <maven.compiler.target>17</maven.compiler.target>
    <revision>0.0.1</revision>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <maven.test.skip>false</maven.test.skip>
    <maven.javadoc.skip>true</maven.javadoc.skip>
    <sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>

    <spring-boot-dependencies.version>3.0.13</spring-boot-dependencies.version>
    <spring.cloud-version>2022.0.5</spring.cloud-version>
    <com.alibaba.cloud.version>2022.0.0.0</com.alibaba.cloud.version>
    <knife4j.version>2.0.5</knife4j.version>

注意使用spring-boot 3.x版本后，jdk必须要17以上。所以本地需要安装jdk17

增加父工程依赖

<dependencyManagement>
        <dependencies>
            <dependency>
                <!-- Import dependency management from Spring Boot -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot-dependencies.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring.cloud-version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>${com.alibaba.cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

创建子工程

使用spring-boot的初始化initializr创建工程并下载放到父工程子目录下
修改pom文件

增加生产者消费者启动配置

新增application.yml文件

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

新增生产者

@Component
@Log
public class FirstProduce implements CommandLineRunner {

    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    @Override
    public void run(String... args) throws Exception {
        log.info("1111");
        SendResult result = rocketMQTemplate.syncSend("TestTopic", "1111");
        log.info(JSONObject.toJSONString(result));
        log.info("2222");


    }
}

新增消费者

package com.hjq.sunshine.demo.rocketmq;

import lombok.extern.java.Log;
import org.apache.rocketmq.spring.annotation.ConsumeMode;
import org.apache.rocketmq.spring.annotation.MessageModel;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.Message;
import org.springframework.stereotype.Service;

import java.util.function.Consumer;

/**
 * @Description
 * @Author hjq
 * @Date 2024/11/21
 */
@Service
@Log
@RocketMQMessageListener(consumerGroup = "MyConsumer", topic = "TestTopic",
        consumeMode = ConsumeMode.CONCURRENTLY, messageModel = MessageModel.BROADCASTING)
public class FirstConsumer implements RocketMQListener<String> {


    @Override
    public void onMessage(String message) {
        log.info("rece msg: " + message);
    }
}

注意事项。使用spring-boot 3.x版本，rocketmq-spring-boot-starter的自动配置会有bug，提示rocketMQTemplate没有bean注入。解决方案参考未注入bean

启动后测试

启动就可以看到如下，正常的生产和消费。
