SpringJms/ActiveMq 消息中间件配置及使用
消息生产者
先在pom.xml加入以下依赖
<dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-client</artifactId> <version>5.13.4</version> </dependency>
src/main/resource下配置spring-jms
spring-jms.xml配置内容
<?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://192.168.25.129:61616"/> </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> <!--这个是队列目的地，导入索引库， 文本信息--> <bean id="queueSolrDestination" class="org.apache.activemq.command.ActiveMQQueue"> <constructor-arg value="pinyougou_queue_solr"/> </bean> <!--这个是队列目的地，删除索引库--> <bean id="queueSolrDeleteDestination" class="org.apache.activemq.command.ActiveMQQueue"> <constructor-arg value="pinyougou_queue_solr_delete"/> </bean> <!--这个是订阅模式 生成商品详细页，文本信息--> <bean id="topicPageDestination" class="org.apache.activemq.command.ActiveMQTopic"> <constructor-arg value="pinyougou_topic_page"/> </bean> <!--这个是订阅模式 删除商品详细页--> <bean id="topicPageDeleteDestination" class="org.apache.activemq.command.ActiveMQTopic"> <constructor-arg value="pinyougou_topic_page_delete"/> </bean> </beans>
控制层，向activeMq发送消息
@RequestMapping("/updateStatus")
public Result updateStatus(Long[] ids,String status){
try {
goodsService.updateStatus(ids, status);
//更新索引库
if("2".equals(status)){//如果是审核通过
//得到需要导入的SKU列表
List<TbItem> itemList = goodsService.findItemListByGoodsIdListAndStatus(ids, status);
if(itemList.size()>0) {
//导入到solr
// itemSearchService.importList(itemList);
//改成由activeMq实现
final String jsonString = JSON.toJSONString(itemList);
jmsTemplate.send(queueSolrDestination, new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(jsonString);
}
});
}else {
System.out.println("没有sku明细数据");
}
//静态页生成
for(final Long goodsId:ids){
//itemPageService.genItemHtml(goodsId);
//改成由activeMq实现
jmsTemplate.send(topicPageDestination, new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(goodsId+"");
}
});
}
}
return new Result(true, "修改状态成功");
} catch (Exception e) {
e.printStackTrace();
return new Result(false, "修改状态失败");
}
}
消息消费者
pom.xml
<!-- activeMq消息队列 --> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-client</artifactId> <version>5.13.4</version> </dependency>
src/main/resource下配置消息消费者配置文件
applicationContext-jms-consumer.xml
<?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://192.168.25.129:61616"/> </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> <!--这个是队列目的地，导入索引库--> <bean id="queueSolrDestination" class="org.apache.activemq.command.ActiveMQQueue"> <constructor-arg value="pinyougou_queue_solr"/> </bean> <!-- 消息监听容器 导入索引库--> <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="queueSolrDestination" /> <property name="messageListener" ref="itemSearchListener" /> <!--监听类--> </bean> <!--这个是队列目的地，导入索引库--> <bean id="queueSolrDeleteDestination" class="org.apache.activemq.command.ActiveMQQueue"> <constructor-arg value="pinyougou_queue_solr_delete"/> </bean> <!-- 消息监听容器 导入索引库--> <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="queueSolrDeleteDestination" /> <property name="messageListener" ref="itemDeleteListener" /> </bean> </beans>
监听类，通过监听类去调用serviceImpl真正业务方法
package com.pinyougou.search.service.impl; import java.util.List; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.alibaba.fastjson.JSON; import com.pinyougou.pojo.TbItem; import com.pinyougou.search.service.ItemSearchService; /*监听类 * activeMq更新索引库-增加 */ @Component public class ItemSearchListener implements MessageListener { @Autowired private ItemSearchService itemSearchService; @Override public void onMessage(Message message) { TextMessage textMessage=(TextMessage)message; try { String text = textMessage.getText();//json字符串 System.out.println("监听到消息:"+text); List<TbItem> itemList = JSON.parseArray(text, TbItem.class); itemSearchService.importList(itemList); System.out.println("导入到solr索引库"); } catch (JMSException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
