直接上使用步骤
1.官网下载activemq服务端,直接解压,无需安装,
,我用的是windows 64bit环境,直接启动
。
2.spring.xml配置
1 <!-- ++++++++++++++++++++++++++++++++++++++++++++消息队列activeMQ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ -->
2 <!--++++++++++++++++++++++++++++++++++++++++++++++++++++发送者+++++++++++++++++++++++++++++++++++++++++++++++++++++ -->
3 <!-- 真正可以产生Connection的ConnectionFactory,由对应的 JMS服务厂商提供 -->
4 <!-- <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
5 <property name="brokerURL" value="tcp://192.168.1.101:61616" />
6 </bean> -->
7
8 <!-- Spring用于管理真正的ConnectionFactory -->
9 <!-- <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory"> -->
10 <!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
11 <!-- <property name="targetConnectionFactory" ref="targetConnectionFactory" /> -->
12 <!-- </bean> -->
13
14 <!-- 使用pool进行链接 -->
15 <!-- 真正可以产生Connection的ConnectionFactory,由对应的 JMS服务厂商提供-->
16 <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
17 <property name="brokerURL" value="tcp://192.168.1.101:61616"/>
18 <!-- 消息传输监听器 处理网络及服务器异常 -->
19 <property name="transportListener">
20 <bean class="com.haobai.activeMQ.ActiveMQTransportListener" />
21 </property>
22 </bean>
23
24 <bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory">
25 <property name="connectionFactory" ref="targetConnectionFactory"/>
26 <property name="maxConnections" value="10"/>
27 </bean>
28
29 <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
30 <property name="targetConnectionFactory" ref="pooledConnectionFactory"/>
31 </bean>
32
33 <!-- Spring提供的JMS工具类,它可以进行消息发送、接收等 -->
34 <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
35 <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
36 <property name="connectionFactory" ref="connectionFactory" />
37 </bean>
38
39 <!--这个是队列目的地 -->
40 <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
41 <constructor-arg>
42 <value>queue</value>
43 </constructor-arg>
44 </bean>
45
46 <!--这个是主题目的地,一对多的-->
47 <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
48 <constructor-arg value="topic"/>
49 </bean>
50 <!--++++++++++++++++++++++++++++++++++++++++++++++++++++接收者+++++++++++++++++++++++++++++++++++++++++++++++++++++ -->
51 <!-- 消息监听器 -->
52 <bean id="consumerMessageListener" class="com.haobai.activeMQ.ConsumerMessageListener" />
53 <!-- 消息监听容器 -->
54 <bean id="jmsContainer"
55 class="org.springframework.jms.listener.DefaultMessageListenerContainer">
56 <property name="connectionFactory" ref="connectionFactory" />
57 <property name="destination" ref="queueDestination" />
58 <property name="messageListener" ref="consumerMessageListener" />
59 </bean>
3.实现消息传输接口TransportListener
1 public class ActiveMQTransportListener implements TransportListener {
2
3 private Logger logger = LoggerFactory.getLogger(this.getClass());
4
5 /**
6 * 对消息传输命令进行监控
7 * @param o
8 */
9 public void onCommand(Object o) {
10 logger.info("onCommand -> 消息服务器消息传输正常...");
11 }
12
13 /**
14 * 监控到异常时触发
15 * @param e
16 */
17 public void onException(IOException e) {
18 logger.error("onException -> 消息服务器连接错误......", e);
19 }
20
21 /**
22 * 当failover时触发
23 */
24 public void transportInterupted() {
25 logger.warn("transportInterupted -> 消息服务器连接发生中断...");
26 }
27
28 /**
29 * 监控到failover恢复后进行触发
30 */
31 public void transportResumed() {
32 logger.info("transportResumed -> 消息服务器连接已恢复...");
33 }
34
35 }
4.生产者的配置,用于发消息
4.1JmsTestController 由于发送对象需要实例化,所以这里直接转成String了
@Controller
public class JmsTestController {
@Autowired
private ProducerService producerService;
@Autowired
@Qualifier("queueDestination")
private Destination destination;
@RequestMapping("test")
@ResponseBody
public String testSend() throws Exception {
//向message中放2个user对象
List<UserInfo> list = new LinkedList<UserInfo>();
UserInfo en = new UserInfo();
en.setId(100);
en.setUsername("name1");
list.add(en);
UserInfo en2 = new UserInfo();
en2.setId(1002);
en2.setUsername("name2");
list.add(en2);
Map<String,Object> mapEntity = new HashMap<String, Object>();
mapEntity.put("user", list);
Map<String,Object> map = new HashMap<String, Object>();
map.put("update", mapEntity);
System.out.println("发送方发送内容为:" + map.toString());
//发送更新数据请求
System.out.println(destination);
producerService.sendMessage(destination, map.toString());
return "jms exute complete";
}
}
4.2 ProducerService
@Service("producerService")
public class ProducerService {
@Autowired private JmsTemplate jmsTemplate;
public void sendMessage(Destination destination, final String message) {
jmsTemplate.send(destination, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
TextMessage textMessage = session.createTextMessage(message);
return textMessage;
}
});
}
}
5.消息接收者,需要实现MessageListener接口
1 public class ConsumerMessageListener implements MessageListener {
2 private Logger logger = LoggerFactory.getLogger(this.getClass());
3
4 /**
5 * 监听发送到消息队列的文本消息
6 *
7 * @param message
8 */
9 public void onMessage(Message message) {
10 TextMessage textMessage = (TextMessage) message;
11 try {
12 System.out.println("接收到的消息内容是:" + textMessage.getText());
13 System.out.println("开始进行解析并调用service执行....");
14 } catch (JMSException e) {
15 logger.error("消息解析失败", e);
16 }
17 }
18
19 }
到此 ,所有配置完成。
tips:如果想要服务器A给服务器B发消息,则需要注意两点:
1.服务器A发消息和 服务器B接受消息需要在同一个队列。
2.服务器A不能实现MessageListener,或者不能和服务器B监听同一个队列,因为activemq的消息队列,消息只能被一个消费者得到,谁先抢到算谁的。A、B同时监听一个队列,有可能A发的消息直接被A抢了,B啥都没有接收到。
好了,暂时就记这么多,以后遇到问题继续增加
