开发含有集团队列操作的服务

发送消息和拉取消息

package com.shtel.paas.service.mq;

import java.io.UnsupportedEncodingException;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;

import com.ctg.mq.api.exception.MQException;
import com.ctg.mq.api.exception.MQProducerException;
import com.shtel.paas.sdk.core.PaasBaseRequest;
import com.shtel.paas.sdk.core.PaasBaseResponse;
import com.shtel.paas.sdk.core.PaasDefaultObject;
import com.shtel.paas.sdk.core.RefreshableRestController;
import com.shtel.paas.sdk.core.mq.ctgmq.EnableCtgMq;
import com.shtel.paas.sdk.core.mq.ctgmq.ICtgMqManager;
import com.shtel.paas.service.mq.domain.MqRespContent;
import com.shtel.paas.service.mq.domain.SendMsgRequest;
//使用@EnableCtgMq注解，系统会自动装配一个ICtgMqManager对象，后续使用@Autowired注入后即可进行队列相关操作
@RefreshableRestController
@EnableCtgMq
public class CtgmqService {

@Autowired ICtgMqManager mq;  @GetMapping("/pullmsg/{topic}") public PaasBaseResponse<MqRespContent> pullmsg(@PathVariable String topic)         throws UnsupportedEncodingException, MQException, InterruptedException {      MqRespContent mrc = new MqRespContent();     mrc.setMsgs(mq.pullMsg(topic));     PaasBaseResponse<MqRespContent> rep = new PaasBaseResponse<>(mrc);     return rep; }  @PostMapping("/sendmsg") public PaasBaseResponse<PaasDefaultObject> sendmsg(@RequestBody PaasBaseRequest<SendMsgRequest> req)         throws MQProducerException, UnsupportedEncodingException {      mq.createMsg(req.getBody().getTopic(), req.getBody().getKey(), req.getBody().getTag(), req.getBody().getMsg().getBytes("utf-8"));     PaasBaseResponse<PaasDefaultObject> rep = new PaasBaseResponse<>(new PaasDefaultObject());      return rep; } 

}
接收回调消息

// 写一个回调类 ，必须实现ICtgMqConsumStrategy，也要是一个springbean，使用@Component注解
@Component
public class DefaultCtgMqConsumStrategy implements ICtgMqConsumStrategy {
private static final Logger logger = LoggerFactory.getLogger(DefaultCtgMqConsumStrategy.class);

@Override public void dealMsg(String body,String key,String tag) {          logger.info(body);  } 

}
队列配置

ctgmq:
clientVersion: V1 #2018.12.28新增1.x的消费模式，通过该配置来区分，可选项V1,V2，默认值V2
disableProducer: false #是否关闭消息生产者，默认false
disablePullConsumer: true #是否关闭消息拉模式消费者，默认false
disableConsumer: true #是否关闭消息推模式消费者，默认false
namesrvAddr: 10.145.205.112:9876 #nameserver地址
authID: admin
authPWD: 123456
tenantID: defaultMQTenantID #租户ID，默认defaultMQTenantID
clusterName: defaultMQBrokerCluster #集群名称，默认是defaultMQBrokerCluster
##############队列性能配置，基本不用变化######################
maxMessageSize: 131072
sendMsgTimeout: 3000
compressMsgBodyOverHowmuch: 4096
consumeOrderly: false
