ActiveMQ消息隊(duì)列技術(shù)融合Spring過(guò)程解析

更新時(shí)間：2019年11月28日 16:59:24 作者：憤青程序猿

這篇文章主要介紹了ActiveMQ消息隊(duì)列技術(shù)融合Spring過(guò)程解析,文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友可以參考下

一、業(yè)務(wù)邏輯

我想在修改一個(gè)物品的狀態(tài)時(shí)，同時(shí)發(fā)送廣播，給對(duì)應(yīng)的監(jiān)聽(tīng)器去實(shí)現(xiàn)，此商品存儲(chǔ)到solr中，同時(shí)通過(guò)網(wǎng)頁(yè)靜態(tài)模板生成一個(gè)當(dāng)前物品的詳情頁(yè)面，此時(shí)用到了廣播機(jī)制

當(dāng)我刪除一個(gè)商品時(shí)，發(fā)送一個(gè)廣播，給對(duì)應(yīng)的監(jiān)聽(tīng)器，同時(shí)刪除solr中對(duì)應(yīng)的物品。

廣播機(jī)制：必須要同時(shí)在線，才能接收我的消息

使用消息中間件需要導(dǎo)入配置文件

      cmsService.createStaticPage(goodsId,goodsData);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

點(diǎn)對(duì)點(diǎn)

當(dāng)我刪除商品時(shí)，我需要對(duì)應(yīng)的服務(wù)進(jìn)行刪除solr中庫(kù)存信息，添加和刪除使用的是同一個(gè)服務(wù)中，使用的是上面的配置文件

//發(fā)布廣播,
  @Autowired
  private ActiveMQTopic topicPageAndSolrDestination;
//在修改的代碼方法中來(lái)廣播發(fā)布當(dāng)前商品的id

if (ids.length>0) {
      jmsTemplate.send(queueSolrDeleteDestination, new MessageCreator() {
        @Override
        public Message createMessage(Session session) throws JMSException {
          TextMessage textMessage = session.createTextMessage(String.valueOf(ids));
          return textMessage;
        }
      });
    }

#執(zhí)行刪除solr中庫(kù)存信息

public class ItemDeleteListener implements MessageListener {
  @Autowired
  private SearchService searchService;

  @Override
  public void onMessage(Message message) {
    ActiveMQTextMessage atm = (ActiveMQTextMessage) message;
    try {
      Long goodsId = Long.valueOf(atm.getText());
      searchService.deleteById(goodsId);
    } catch (JMSException e) {
      e.printStackTrace();
    }
  }
}
