ActiveMQ的简单使用

项目中使用的介绍

一、运行ActiveMQ

在文件路径下...\apache-activemq-5.13.3\bin\win64

运行activemq.bat 

这是系统中的使用，运行后还可以访问相应的页面。

二、项目中的实践

1.依赖的jar包

<dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jms</artifactId>        </dependency>        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>activemq-broker</artifactId>        </dependency>        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>activemq-pool</artifactId>        </dependency>        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>activemq-spring</artifactId>        </dependency>        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>artemis-jms-client</artifactId>        </dependency>        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>artemis-jms-server</artifactId>        </dependency>

2.配置ActiveMQ的配置，要和运行的保持一致，在commom.properties文件中。

activemq.broker.url=tcp://127.0.0.1:61616activemq.user=adminactivemq.password=adminactivemq.name=datacenter.testactivemq.name.access=datacenter.access

3.applicationContext-mq.xml 中配置

<!-- 1.配置ActiveMQ 连接工厂 -->    <amq:connectionFactory id="creditMQConnectionFactory"                           brokerURL="${activemq.broker.url}" userName="${activemq.user}" password="${activemq.password}"  />    <!-- 2.配置缓存 ConnectionFactory -->    <bean id="creditMQconnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">        <property name="targetConnectionFactory" ref="creditMQConnectionFactory"/>        <property name="sessionCacheSize" value="100" />    </bean>    <!-- 定义JmsTemplate的Queue类型 -->    <bean id="creditJmsTemplate" class="org.springframework.jms.core.JmsTemplate">        <constructor-arg ref="creditMQConnectionFactory" />        <property name="pubSubDomain" value="false" />    </bean>    <!-- 定义授权队列消费者    <bean id="creditConsumer" class="com.itom.mq.consumer.CreditConsumer"/>-->    <!-- 定义Queue监听器 -->    <jms:listener-container destination-type="queue" container-type="default" connection-factory="creditMQconnectionFactory" acknowledge="auto">        </jms:listener-container>    <!--运营相关配置结束-->

4.编写生产者和消费者

  1） 生产者

import org.apache.activemq.command.ActiveMQQueue;import org.springframework.jms.core.JmsTemplate;import org.springframework.stereotype.Component;import javax.annotation.Resource;import javax.jms.Queue;import java.util.Map;import java.util.concurrent.ConcurrentHashMap;@Componentpublic class CreditProducer {    private Map<String ,Queue> cacheQueue = new ConcurrentHashMap<String ,Queue>();    @Resource    private JmsTemplate creditJmsTemplate;    public void pushCreditData(String queueName ,Object message){        Queue queue = cacheQueue.get(queueName);        if(queue == null){            queue = new ActiveMQQueue(queueName);            cacheQueue.put(queueName,queue);        }        this.creditJmsTemplate.convertAndSend(queue, message);    }}

  2） 消费者：

public class MessageReceiver implements MessageListener {    //自己定义的类，使用线程池来处理消息    @Resource(name = "messageComputePool")    MessageComputePool pool;    public void onMessage(Message message) {        if(message instanceof TextMessage) {            TextMessage textMessage = (TextMessage) message;            try {                String text = textMessage.getText();                System.out.println(String.format("Received: %s",text));                JSONObject jsonObj = (JSONObject)JSONObject.parse(text);                ...                //消费者接收到消息就可以进行处理了            } catch (JMSException e) {                e.printStackTrace();            }        }    }}

  3）使用生产者推消息

@Service("collectService ")public class CollectServiceImpl implements CollectService {      public static final Logger LOG  = LoggerFactory.getLogger(CollectServiceImpl.class);      @Resource      private CreditProducer creditProducer;      @Override      public void collect(CollectParameter parameter) {            Map dataMap = new HashMap();            dataMap.put("sourceCode", parameter.getValue());            dataMap.put("userId",parameter.getUserid());                       creditProducer.pushCreditData("itom.activemq.access", JSON.toJSONString(dataMap));        }    }}
