springmvc和activemq的整合使用

一、簡介:ActiveMQ 是Apache出品,最流行的,能力強勁的開源消息總線。ActiveMQ 是一個徹底支持JMS1.1和J2EE 1.4規範的 JMS Provider實現,儘管JMS規範出臺已是好久的事情了,可是JMS在當今的J2EE應用中間仍然扮演着特殊的地位。linux

二、建議在使用之前瞭解一下jms的一些知識web

三、第一步:咱們部署相關的activemq(我這裏是採用本身本地linux虛擬機來實現的,以模擬中間推送消息的原理)spring

  activemq下載地址:http://archive.apache.org/dist/activemq/我用的是目前最新的5.14.5版本apache

這裏有這個zip的是windows用的,tar.gz的是Linux用的。我這裏採用的Linux部署windows

將activemq的tar解壓啓動
啓動方式在:spring-mvc

/root/apache-activemq-5.14.5/bin/linux-x86-64

啓動:./activemq start 暫停: ./activemq stop 重啓:./activemq restart
啓動起來後,訪問地址爲:http://192.168.5.10:8161/admin 帳號密碼:都是admin(默認)session

開機自啓:vi /etc/rc.local 而後在末尾加入mvc

su - root -c '/usr/local/activemq/bin/activemq start'maven

這樣整個activemq就部署好了,由於activemq是單獨的項目,啓動事後不用再理會
四、第二步:Java代碼實現,具體項目的配置tcp

  1)導包:pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.troy</groupId>
  <artifactId>activemq</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>
  <dependencies>
      <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>3.2.8.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.apache.activemq</groupId>
      <artifactId>activemq-spring</artifactId>
      <version>5.14.5</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jms</artifactId>
      <version>3.2.8.RELEASE</version>
    </dependency>
  </dependencies>
</project>

  2)根據相關jar的屬性進行xml的配置
  (1)配置activemq的鏈接spring-config.properties

activemq_url=tcp://192.168.5.10:61616
activemq_username=admin
activemq_password=admin

  (2)配置相關的activeMQ

        <property name="destination" ref="topic"/>
        <property name="messageListener" ref="topicMessageListen"/>
    </bean>

</beans>

  3)代碼層面我謝了兩個:方便測試
  (1)一個是監聽接口獲取數據(TopicMessageListen)

public class TopicMessageListen implements MessageListener{

    public void onMessage(Message message) {        
        System.out.println("監聽==================監聽");
        try {
            System.out.println(message);
            TextMessage tm = (TextMessage)(message);
            System.out.println(tm.getText());
        } catch (Exception e) {
            e.printStackTrace();
            
        }
        
    }

}

由於咱們在配置文件裏面加入了監聽,這裏只須要實現MessageListener接口就能夠了,而後在處理message信息
  (2)發送消息(TopicSendMessage)

public class TopicSendMessage {
    private  ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring/spring-mvc.xml");
    private  JmsTemplate jmsTemplate = (JmsTemplate) ac.getBean("jmsTemplate");
    public void send(){
        
        
        jmsTemplate.send(new MessageCreator() {
            
            public Message createMessage(Session session) throws JMSException {
                TextMessage msg = session.createTextMessage();
                msg.setText("發送數據++++++++++++發送數據");
                System.out.println("發送數據++++++++++++發送數據");
                return msg;
            }
        });
    }
    
    public void receive(){
        Message msg = jmsTemplate.receive();
        TextMessage tm = (TextMessage)msg;
        System.out.println("非監聽------------------非監聽");
        System.out.println(msg);
    }
    
    public static void main(String[] args) {
        new TopicSendMessage().send();
        
    }
}

說明:發送數據的方式基本上大同小異經過獲取jmsTemplate來實現發送的操做,由於我沒有直接啓動容器,因此採用獲取bean的方式
     接收上面沒有運行,由於接收的這個receive()方法是同步運行的,會卡線程這裏不作演示,我經過啓動兩個方式測試能夠成功的,可是不建議這種方式

  (3)展現結果:

  (4)activemq的簡單使用和配置方式就才很少這麼多

五、個人項目結構
