RocketMq入门案例

修改社交会员

//封装发送入参:

SocialMember socialMember = new SocialMember();

socialMember.setLastUpd(new Date()); //大数据要求设置修改时间

String getmId = socialMember.setmId(request.getData().getmId();));

}

sendRocketMqForUpdateMember(socialMember);

rocketMq 发送消息

public void sendRocketMqForUpdateMember(SocialMember socialMember) {

try {

BlockChainMemberUpdateItem item = new BlockChainMemberUpdateItem();

item.setFlMemberId(String.valueOf(socialMember.getmId()));// 会员id

item.setFlToken(null); // token

item.setFlRole(null); // 会员角色

item.setFlCategory("2");// 会员类别

item.setFlStatus("0"); // 会员状态

item.setFlOper("update"); // 对数据进行的操作（新增还是更新 insert或者update）

item.setFlUpdated(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));// 会员的更新时间

// 由会员信息组成的一个json字符串

item.setFlData(socialMember);

// 数据签名

String plainTextData = GsonUtil.toJson(item, BlockChainMemberUpdateItem.class);

String encryptData = EccService.sign(plainTextData,BlockChainAdapter.SOCIAL_TYPE);

LogMgr.sysInfo("获取的签名数据：{}", encryptData);

BlockChainMemberRequest<BlockChainMemberUpdateItem> request = new BlockChainMemberRequest<BlockChainMemberUpdateItem>();

request.setData(item);

request.setFlDataSignature(encryptData);

String jsonData = GsonUtil.toJson(request, BlockChainMemberRequest.class);

rocketMqProductor.sendMsg(null, BLOCK_CHAIN_TOPIC, BLOCK_CHAIN_UPDATE_TAG, null, jsonData);

//========================标签发送数据=======================

LabelMemberItem labelMemberItem = new LabelMemberItem();

labelMemberItem.setFlMemberId(String.valueOf(String.valueOf(socialMember.getmId()))); // 会员id

labelMemberItem.setFlCategory("1");// 会员类别

labelMemberItem.setFlStatus("0"); // 会员状态

labelMemberItem.setFlOper("update"); // 对数据进行的操作（新增还是更新 insert或者update）

labelMemberItem.setFlCreated(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));// 会员的更新时间

labelMemberItem.setFlData(socialMember);

String labelJsonData = FastJsonUtil.parseToJSON(labelMemberItem);

rocketMqProductor.sendMsg(null, LABEL_TOPIC, LABEL_UPDATE_TAG, null, labelJsonData);

} catch (Exception e) {

LogMgr.sysInfo("rocketMq send message fail");

}

自己封装方法

package com.foriseland.fas.member.mq;

import com.foriseland.fjf.mq.broadcasting.BroadcastProducer;

import org.apache.rocketmq.client.producer.SendResult;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Component;

/**

@Component

public class RocketMqProductor {

private static final Logger logger = LoggerFactory.getLogger(RocketMqProductor.class);

@Autowired

private BroadcastProducer producer;

static int startOnly = 0;

public SendResult sendMsg(String producerGroup, String topic, String tags, String keys, String msg) {

if (producerGroup == null) {

producerGroup = "-";

}

if (startOnly == 0) {

try {

producer.setProducerGroup("-", producerGroup);

producer.getRocketProducer().setRetryTimesWhenSendFailed(5);

producer.start();

startOnly++;

} catch (Exception e) {

logger.error("start rocketMq exception:{}", e);

return null;

}

SendResult sendResult = null;

try {

sendResult = producer.send(producerGroup, topic, tags, keys, msg);

logger.info("rocketMq发送结果:{}", sendResult);

} catch (Exception e) {

logger.error("rocketMq send message exception:{}", e);

} finally {

shutDown();

}

return sendResult;

}

public void shutDown() {

// startOnly = 0;

// producer.shutdown();

}

底层实现---直接调用

@SuppressWarnings("static-access")

public SendResult send(String producerGroup, String topic, String tags, String keys, String body) throws UnsupportedEncodingException,MQClientException, RemotingException, MQBrokerException, InterruptedException {

rocketProducer.newInstance().setProducerGroup(producerGroup );

//producer.start();

long startTime = System.currentTimeMillis();

Message message = new Message(topic, tags, keys, body.getBytes(RemotingHelper.DEFAULT_CHARSET));

int messageDelayTimeLevel = rocketProducer.getRocketMqClientConfig().getRocketConfig().getMessageDelayTimeLevel();

message.setDelayTimeLevel(messageDelayTimeLevel);

SendResult sendResult = rocketProducer.newInstance().send(message);

long endTime = System.currentTimeMillis();

logger.info("send cost:" + (endTime - startTime) + "ms");

logger.info(sendResult);

return sendResult;

}
