# 解壓至: /usr/local/rocketmq-all-4.5.1-bin-release
# 啓動/關閉服務: 
    rocketmq
        # 啓動:
            /usr/local/rocketmq-all-4.5.1-bin-release/bin/mqnamesrv -c /usr/local/rocketmq-all-4.5.1-bin-release/conf/namesrv.properties -n "192.168.1.180:6500" &
            # 設置自定義端口: 6500
            -n /usr/local/rocketmq-all-4.5.1-bin-release/conf/namesrv.properties
            # 文件內容是: 
                listenPort=6600
        # 關閉: 
            /usr/local/rocketmq-all-4.5.1-bin-release/bin/mqshutdown namesrv

    mqbroker:
        # 啓動:  autoCreateTopicEnable=true(允許微服務創建topic)
            /usr/local/rocketmq-all-4.5.1-bin-release/bin/mqbroker -n "192.168.1.180:6500" autoCreateTopicEnable=true &
        # 關閉: 
        /usr/local/rocketmq-all-4.5.1-bin-release/bin/mqshutdown broker

2.生產者-微服務(發送-隊列消息)

# 消息體-對象:
@Data
@Builder
@ToString
public class MemberMoneyMessage {
    int memberId;
    String event;
    double money;
}

# 發送消息:
@Autowired
RocketMQTemplate rocketMQTemplate;
....
rocketMQTemplate.convertAndSend(
            "member-money-act",
            MemberMoneyMessage.builder()
                    .event("pay-order")
                    .memberId(50)
                    .money(100)
                    .build()
    );
....

配置rocket服務端:
rocketmq:
name-server: tsca.cc:6600
producer:
    group: tsca-group

3.消費者-微服務(處理-隊列消息)

# 監聽處理:
@Service
@RocketMQMessageListener(consumerGroup = "tsca-group",topic = "member-money-act")
@Slf4j
public class MemberMoneyMqListener implements RocketMQListener<MemberMoneyMessage> {
    @Override
    public void onMessage(MemberMoneyMessage memberMoneyMessage) {
        log.info("收到-用戶餘額變動");
        log.info(JSON.toJSONString(memberMoneyMessage));
    }
}

# 配置:
rocketmq:
    name-server: tsca.cc:6600
    producer:
        group: tsca-group
