1 下载部署 RocketMQ
进入 Apache RocketMQ官网 下载你需要的版本的二进制或者源码(需要手动编译)。
如果选择 Source 需要自己编译
解压或者编译好 RocketMQ-4.5.2，并将对应的 RocketMQ 文件目录添加到 Windows 环境变量中。
# 切换到 RocketMQ 的 bin 目录
cd C:UsersAdministratorVideosRocketMQ-4.5.2bin
# 启动 RocketMQ nameserver
start mqnamesrv.cmd
# 启动 RocketMQ broker
start mqbroker.cmd -n 127.0.0.1:9876 autoCreateTopicEnable=true
# 关闭 RocketMQ nameserver
mqshutdown.cmd namesrv
# 关闭 RocketMQ broker
mqshutdown.cmd broker
使用Git克隆或者直接下载 Apache RocketMQ 工具集。
切换到 rocketmq-console 的目录，找到 application.properties ，按自己的实际情况修改 rocketmq-console 的配置。
server.cOntextPath=
server.port=8077
### SSL setting
#server.ssl.key-store=classpath:rmqcngkeystore.jks
#server.ssl.key-store-password=rocketmq
#server.ssl.keyStoreType=PKCS12
#server.ssl.keyAlias=rmqcngkey
#spring.application.index=true
spring.application.name=rocketmq-console
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true
logging.cOnfig=classpath:logback.xml
#if this value is empty,use env value rocketmq.config.namesrvAddr NAMESRV_ADDR | now, you can set it in ops page.default localhost:9876
rocketmq.config.namesrvAddr=
#if you use rocketmq version <3.5.8, rocketmq.config.isVIPChannel should be false.default true
rocketmq.config.isVIPChannel=
#rocketmq-console's data path:dashboard/monitor
rocketmq.config.dataPath=/tmp/rocketmq-console/data
#set it false if you don't want use dashboard.default true
rocketmq.config.enableDashBoardCollect=true
#set the message track trace topic if you don't want use the default one
rocketmq.config.msgTrackTopicName=
rocketmq.config.ticketKey=ticket
#Must create userInfo file: ${rocketmq.config.dataPath}/users.properties if the login is required
rocketmq.config.loginRequired=false
切换到 rocketmq-console 的目录
# 1
cd C:UsersAdministratorVideosrocketmq-externals-masterrocketmq-console
# 2
mvn clean package -Dmaven.test.skip=true
编译完成后 rocketmq-console 的目录会多出一个 target 目录，进入 target 目录，使用Java CMD 命令运行 rocketmq-console
cd target
java -jar rocketmq-console-ng-1.0.1.jar

监听器属于SpringMVC所以需要在启动内中加入@ServletComponentScan(“com.xu.springboot.listener”)
package com.xu.springboot.listener;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionIdListener;
import org.springframework.stereotype.Component;
import com.xu.springboot.rocketmq.ConsumerConfigure;
@Component
public class Consumer extends ConsumerConfigure implements HttpSessionIdListener {
@Override
public void sessionIdChanged(HttpSessionEvent se, String oldSessionId) {
super.consumer();
}
}
修改启动类代码加入 @ServletComponentScan(“com.xu.springboot.listener”) Application.java
package com.xu.springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
@SpringBootApplication
@ServletComponentScan("com.xu.springboot.listener")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
package com.xu.springboot.controller;
import org.apache.rocketmq.client.producer.SendCallback;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;
import org.apache.rocketmq.remoting.common.RemotingHelper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.xu.springboot.rocketmq.ProducerConfigure;
@Controller
@RequestMapping("/rocketmq")
public class RocketMQController {
@Autowired
private ProducerConfigure producer;
@RequestMapping("/order1")
@ResponseBody
public Object order1(String msg,String tag) throws Exception {
Message message=new Message("test_topic",tag,msg.getBytes(RemotingHelper.DEFAULT_CHARSET));
SendResult result=producer.getProducer().send(message);
System.out.println("生产者：MsgId = "+result.getMsgId()+"t发送状态：SendStatus = "+result.getSendStatus());
return result.getSendStatus();
}
@RequestMapping("/order2")
@ResponseBody
public void order2(String msg,String tag) throws Exception {
Message message=new Message("test_topic",tag,msg.getBytes(RemotingHelper.DEFAULT_CHARSET));
producer.getProducer().send(message,new SendCallback() {
@Override
public void onSuccess(SendResult sendResult) {
System.out.println("生产者：MsgId = "+sendResult.getMsgId()+"t发送状态：SendStatus = "+sendResult.getSendStatus());
}
@Override
public void onException(Throwable e) {
System.out.println("发送失败");
}
});
}
}
