标签：添加 sea listen session 队列 try service containe sda
我想在修改一个物品的状态时，同时发送广播，给对应的监听器去实现，此商品存储到solr中，同时通过网页静态模板生成一个当前物品的详情页面，此时用到了广播机制
当我删除一个商品时，发送一个广播，给对应的监听器，同时删除solr中对应的物品。
使用消息中间件需要导入配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amq="http://activemq.apache.org/schema/core" xmlns:jms="http://www.springframework.org/schema/jms" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供--> <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://192.168.200.128:61616"/> </bean> <!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory --> <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory"> <!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory --> <property name="targetConnectionFactory" ref="targetConnectionFactory"/> </bean> <!-- Spring提供的JMS工具类，它可以进行消息发送、接收等 --> <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate"> <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 --> <property name="connectionFactory" ref="connectionFactory"/> </bean> <!-- 发布订阅模式, 商品导入索引库和生成静态页面 --> <bean id="topicPageAndSolrDestination" class="org.apache.activemq.command.ActiveMQTopic"> <!--将商品上架所有的商品的id发送到这个队列中--> <constructor-arg value="youlexuan_topic_page_solr"/> </bean> <!-- 点对点模式--> <bean id="queueSolrDeleteDestination" class="org.apache.activemq.command.ActiveMQQueue"> <!--将商品上架所有的商品的id发送到这个队列中--> <constructor-arg value="youlexuan_queue_solr_delete"/> </bean> </beans>
发布广播：
if ("1".equals(status)){
jmsTemplate.send(topicPageAndSolrDestination, new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
TextMessage textMessage = session.createTextMessage(String.valueOf(id));
return textMessage;
}
});
}
监听器1，将当前商品存入solr中:操作solr的服务器配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amq="http://activemq.apache.org/schema/core" xmlns:jms="http://www.springframework.org/schema/jms" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--产生Connection--> <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://192.168.200.128:61616"/> </bean> <!--spring 管理connectionFactory--> <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory"> <property name="targetConnectionFactory" ref="targetConnectionFactory"/> </bean> <!--发布订阅模式 将数据导入solr 索引库--> <bean id="topicPageAndSolrDestination" class="org.apache.activemq.command.ActiveMQTopic"> <constructor-arg value="youlexuan_topic_page_solr"/> </bean> <!--发布订阅模式 消息监听容器 将数据导入solr 索引库--> <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="topicPageAndSolrDestination" /> <property name="messageListener" ref="pageAndSolrListener" /> </bean>
#对应的用来监听执行往solr中保存库存的消息 <bean id="pageAndSolrListener" class="com.ghh.sellergoods.service.listener.ItemSearchListener"></bean> <!--点对点的模式 删除索引库--> <bean id="queueSolrDeleteDestination" class="org.apache.activemq.command.ActiveMQQueue"> <!--指定从这个队列中 接收下架商品的--> <constructor-arg value="youlexuan_queue_solr_delete"/> </bean> <!--点对点的模式 消息监听器 删除索引库--> <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="queueSolrDeleteDestination" /> <property name="messageListener" ref="itemDeleteListener" /> </bean> <bean id="itemDeleteListener" class="com.ghh.sellergoods.service.listener.ItemDeleteListener"></bean> </beans>
监听器类
public class ItemSearchListener implements MessageListener { @Autowired private SearchService searchService; @Autowired private ItemDao itemDao; @Override public void onMessage(Message message) { //获取生产者发布的广播，往solr中添加库存列表 ActiveMQTextMessage atm = (ActiveMQTextMessage) message; try { //获取广播中的数据。 Long goodsId = Long.valueOf(atm.getText()); //通过传过来的商品id去查询库存表 ItemQuery query = new ItemQuery(); ItemQuery.Criteria criteria = query.createCriteria(); criteria.andGoodsIdEqualTo(goodsId); //查询对应商品id的库存表 List<Item> items = itemDao.selectByExample(query);
//调用对应的方法，往solr中添加当前商品对应库存信息 searchService.importList(items); } catch (JMSException e) { e.printStackTrace(); } } }
监听器类2：配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amq="http://activemq.apache.org/schema/core" xmlns:jms="http://www.springframework.org/schema/jms" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--产生Connection工厂类--> <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://192.168.200.128:61616"/> </bean> <!--spring管理工厂类--> <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory"> <property name="targetConnectionFactory" ref="targetConnectionFactory"/> </bean> <!--发布订阅模式 生成页面--> <bean id="topicPageAndSolrDestination" class="org.apache.activemq.command.ActiveMQTopic"> <!--指定从这个队列上获取上架的商品id--> <constructor-arg value="youlexuan_topic_page_solr"/> </bean> <!--发布订阅模式 消息监听器 生成页面--> <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="topicPageAndSolrDestination" /> <property name="messageListener" ref="pageListener" /> </bean> <bean id="pageListener" class="com.ghh.core.service.listener.PageListener"></bean> </beans>
监听器类2：生成静态网页模板
public class PageListener implements MessageListener { @Autowired private CmsService cmsService; @Override public void onMessage(Message message) { ActiveMQTextMessage atm = (ActiveMQTextMessage) message; try { Long goodsId = Long.valueOf(atm.getText()); Map<String, Object> goodsData = cmsService.findGoodsData(goodsId); cmsService.createStaticPage(goodsId,goodsData); } catch (Exception e) { e.printStackTrace(); } } }
当我删除商品时，我需要对应的服务进行删除solr中库存信息，添加和删除使用的是同一个服务中，使用的是上面的配置文件
//发布广播, @Autowired private ActiveMQTopic topicPageAndSolrDestination; //在修改的代码方法中来广播发布当前商品的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; } }); }
#执行删除solr中库存信息
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(); } } }
