SpringBoot整合RocketMQ的方法详解
作者:羁客%
一:Ubuntu安装RocketMQ
1.下载(在下面地址选择自己需要的版本的rocketmq)
http://rocketmq.apache.org/release_notes/
2.解压,更改配置
将下载的zip文件解压到自己需要安装的位置
在unbuntu系统下需要修改安装跟目录下的两个文件
bin/runserver.sh 和 bin/runbroker.sh 文件
(1).都修改两个文件的 java_home=/java安装HOME路径/
(2).都修改两个文件的 java_home=/java安装HOME路径/jre/
(3).修改runserver.sh内存
JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m" # 原来是:JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn4g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
(4).修改runbroker.sh内存
JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g # 原来是:JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g
(5).创建日志目录
mkdir logs
3.后台挂载启动 mqnamesrv(在安装根目录下执行)
nohup sh bin/mqnamesrv > logs/namesrv.log 2>&1 &
5.查看mqnamesrv是否启动成功
查看 logs/namesrv.log 文件出现以下提示表示启动成功!
The Name Server boot success. serializeType=JSON
6.安装 mqbroker
Broker是 RocketMQ 的核心,大部分'重量级'工作都是由 Broker完成的,
包括接收 Producer 发过来的消息、处理 Consumer 的消费消息请求、消息的持 久化存储、消息的 HA 机制以及服务端过滤功能等 。
(1).更改broker配置,在安装根目录下conf/broker.conf文件 添加一行
brokerIP1 = 127.0.0.0 # IP根据自己电脑服务器修改一下,最好不要使用这个,ifconfig就可以查看到自己服务器的IP
(2).挂载启动 mqbroker(在安装根目录下)
nohup sh bin/mqbroker -c conf/broker.conf -n localhost:9876 > logs/broker.log 2>&1 &
(3).查看 mqbroker 是否启动成功
查看 logs/broker.log 文件出现以下提示表示启动成功!
The broker[broker-a, 127.0.0.0:10911] boot success. serializeType=JSON and name server is localhost:9876
7.关闭broker和nameserver(在安装根目录下执行)
./bin/mqshutdown broker ./bin/mqshutdown namesrv
8.创建一个topic
./bin/mqadmin updateTopic -n '127.0.0.0:9876' -c MyCluster -t MyTopic
9.查看集群状态
./bin/mqadmin clusterList -n localhost:9876
二:添加RocketMQ依赖
<!--rocket mq 依赖--> <dependency> <groupId>org.apache.rocketmq</groupId> <artifactId>rocketmq-spring-boot-starter</artifactId> <version>2.1.1</version> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </exclusion> </exclusions> </dependency>
三:在application中添加RocketMQ配置
#rocketmq 配置 rocketmq: name-server: 127.0.0.0:9876 #IP根据自己电脑服务器配置的 mqbroker->brokerIP1 修改一下,最好不要使用这个 producer: group: rocketmq_group myrocketmq-config: my-topic: rocketmq_topic my-consumer-group: rocketmq_group_consumer
四:编写消费者,消息生产者,消息实体类(自定义)
//Rocket消费者 @Slf4j @Component @RocketMQMessageListener(consumerGroup = "${myrocketmq-config.my-consumer-group}", topic = "${myrocketmq-config.my-topic}") public class RocketConsumer implements RocketMQListener<RocketmqVo> { @Override public void onMessage(RocketmqVo rocketmqVo) { log.info("收到RocketMQ消息:{}",rocketmqVo); } }
//Rocket生产者 @Slf4j @Component public class RocketProduce { @Value("${myrocketmq-config.my-topic}") private String mqTopic; @Value("${myrocketmq-config.my-consumer-group}") private String mqConsumerGroup; @Autowired private RocketMQTemplate mqTemplate; /** * 同步发送 * * @param title 发送消息 * @param data 消息内容 */ public void sync(String title, Object data) { String time = new SimpleDateFormat("yyyyMMdd HH:mm:ss").format(new Date()); RocketmqVo rocketmqVo = new RocketmqVo(mqConsumerGroup, mqTopic, title, time, data); SendResult sendResult = mqTemplate.syncSend(mqTopic, rocketmqVo); log.info("同步发送:{}", rocketmqVo); log.info("同步发送消息结果:{}", sendResult); } /** * 异步发送 * * @param title 发送消息 * @param data 消息内容 */ public void async(String title, Object data) { String time = new SimpleDateFormat("yyyyMMdd HH:mm:ss").format(new Date()); RocketmqVo rocketmqVo = new RocketmqVo(mqConsumerGroup, mqTopic, title, time, data); log.info("异步发送:{}", rocketmqVo); mqTemplate.asyncSend(mqTopic, rocketmqVo, new SendCallback() { @Override public void onSuccess(SendResult var1) { log.info("异步发送成功:{}", var1); } @Override public void onException(Throwable var1) { log.info("异步发送失败:{}", var1.getMessage()); } }); } /** * 单向发送 * * @param title 发送消息 */ public void oneway(String title, Object data) { String time = new SimpleDateFormat("yyyyMMdd HH:mm:ss").format(new Date()); RocketmqVo rocketmqVo = new RocketmqVo(mqConsumerGroup, mqTopic, title, time, data); mqTemplate.sendOneWay(mqTopic, rocketmqVo); log.info("单向发送:{}", rocketmqVo); } } //Rocket消息实体 @Data @AllArgsConstructor @NoArgsConstructor @ToString public class RocketmqVo { @Value("${myrocketmq-config.my-consumer-group}") private String group; @Value("${myrocketmq-config.my-topic}") private String topic; private String title; private String date; private Object data; public RocketmqVo(String title, String date, Object data) { this.title = title; this.date = date; this.data = data; } }
五:测试Controller
@RestController @RequestMapping("/mqtest") public class RocketController { @Resource private RocketProduce producer; @RequestMapping("/sendMessageSync/{msg}") public String sendMessageSync(@PathVariable("msg") String message) { producer.sync(message, null); return "消息发送完成"; } @RequestMapping("/sendMessageAsync/{msg}") public String sendMessageAsync(@PathVariable("msg") String message) { producer.async(message, null); return "消息发送完成"; } @RequestMapping("/sendMessageOneway/{msg}") public String sendMessageOneway(@PathVariable("msg") String message) { producer.oneway(message, null); return "消息发送完成"; } }
