spring boot学习第二十三篇：Spring Boot集成RocketMQ

前置条件先安装好RocketMQ

希望在Window10安装rocketMQ并简单使用，可以参考如下文章：

Window10安装rocketMQ并简单使用-CSDN博客

1、pom.xml文件里面加上依赖

<dependency><groupId>org.apache.rocketmq</groupId><artifactId>rocketmq-spring-boot-starter</artifactId><version>2.2.3</version></dependency>

pom.xml全文如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.6.4</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.hmblogs</groupId><artifactId>hmblogs</artifactId><version>0.0.1-SNAPSHOT</version><name>hmblogs</name><description>hmblogs</description><properties><java.version>8</java.version><druid.version>1.2.8</druid.version><log4jdbc.version>1.16</log4jdbc.version><es.version>7.9.2</es.version><easyexcel.version>3.3.4</easyexcel.version><redisson.version>2.15.2</redisson.version></properties><dependencies><dependency><groupId>org.apache.rocketmq</groupId><artifactId>rocketmq-spring-boot-starter</artifactId><version>2.2.3</version></dependency><!-- 操作minio的java客户端--><dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.2.1</version></dependency><!--        jwt鉴权相应依赖--><dependency><groupId>ch.qos.logback</groupId><artifactId>logback-classic</artifactId><version>1.2.3</version></dependency><dependency><groupId>io.jsonwebtoken</groupId><artifactId>jjwt-jackson</artifactId><version>0.11.2</version></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.8.16</version></dependency><dependency><groupId>org.redisson</groupId><artifactId>redisson</artifactId><version>${redisson.version}</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>easyexcel</artifactId><version>${easyexcel.version}</version></dependency><dependency><groupId>org.redisson</groupId><artifactId>redisson</artifactId><version>3.16.0</version></dependency><!-- druid数据源驱动 --><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>${druid.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- mybatis --><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.5.3.1</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><!--Mysql依赖包--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><!--lombok插件--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><!--监控sql日志--><dependency><groupId>org.bgee.log4jdbc-log4j2</groupId><artifactId>log4jdbc-log4j2-jdbc4.1</artifactId><version>${log4jdbc.version}</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.9</version></dependency><dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId></dependency><dependency><groupId>org.apache.kafka</groupId><artifactId>kafka-clients</artifactId></dependency><dependency><groupId>org.springframework.kafka</groupId><artifactId>spring-kafka</artifactId></dependency><!-- high client--><dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-high-level-client</artifactId><version>${es.version}</version><exclusions><exclusion><groupId>org.elasticsearch</groupId><artifactId>elasticsearch</artifactId></exclusion><exclusion><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-client</artifactId></exclusion></exclusions></dependency><!-- rest-high-level-client 依赖如下2个jar --><dependency><groupId>org.elasticsearch</groupId><artifactId>elasticsearch</artifactId><version>${es.version}</version></dependency><dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-client</artifactId><version>${es.version}</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId></dependency><!--        <dependency>-->

2、application.yml配置文件需要加上如下配置：

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

该配置文件全部内容如下：

server:port: 8081servlet.context-path: /hmblogs#配置数据源
spring:datasource:druid:db-type: com.alibaba.druid.pool.DruidDataSourcedriverClassName: net.sf.log4jdbc.sql.jdbcapi.DriverSpyurl: jdbc:log4jdbc:mysql://${DB_HOST:localhost}:${DB_PORT:3306}/${DB_NAME:hmblogs}?useSSL=true&allowPublicKeyRetrieval=true&serverTimezone=UTCusername: ${DB_USER:root}password: ${DB_PWD:demo}redis:host: localhostport: 6379password: hemingdatabase: 10
#  data:

#      port: 27017
#      username: hmblogs
#      password: demo
#      database: hmblogs
#      authentication-database: adminservlet:multipart:max-file-size: 10MBmax-request-size: 10MB#minio配置minio:access-key: Irr1hKVWRacP91HAqJ60secret-key: demourl: http://localhost:9000  #访问地址bucket-name: hmblogs-bucketes:host: 43.138.0.199port: 9200scheme: httpuser: elasticpassword: democaptcha:width: 200height: 100rocketmq:name-server: 127.0.0.1:9876producer:group: superman-producer-group

3、生产者代码如下：

package com.hmblogs.backend.controller;import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/mq")
@Slf4j
public class MqProducerController {@Autowiredprivate RocketMQTemplate rocketMQTemplate;@RequestMapping("/producer")public String producer(@RequestParam("msg") String msg){log.info("我要发消息："+msg);rocketMQTemplate.convertAndSend("first-topic","你好" + msg);return "connected";}
}

4、消费者代码如下：

package com.hmblogs.backend.util;import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;@Component
@RocketMQMessageListener(topic = "first-topic", consumerGroup = "superman-consumer-group")
@Slf4j
public class MqConsumer implements RocketMQListener<String> {@Overridepublic void onMessage(String message) {log.info("我的RocketMQ接收到的消息为："+message);//在此处添加自己要加的逻辑}
}

5、调用生产者的生产消息接口
