Spring整合ActiveMQ

六、Spring整合ActiveMQ

1、添加Spring支持JMS的包（添加依赖）

 <dependencies>
        <!--  activemq  所需要的jar 包-->
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-all</artifactId>
            <version>5.15.0</version>
        </dependency>
        <!--  嵌入式activemq的broker所需要的依赖包   -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.10.1</version>
        </dependency>
        <!-- activemq连接池 -->
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-pool</artifactId>
            <version>5.15.10</version>
        </dependency>
        <!-- spring支持jms的包 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
            <version>5.2.1.RELEASE</version>
        </dependency>
        <!--spring相关依赖包-->
        <dependency>
            <groupId>org.apache.xbean</groupId>
            <artifactId>xbean-spring</artifactId>
            <version>4.15</version>
        </dependency>
        <!-- Spring核心依赖 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>4.3.23.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.3.23.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>4.3.23.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-orm</artifactId>
            <version>4.3.23.RELEASE</version>
        </dependency>
</dependencies>

2、Spring的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"

       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
        http://www.springframework.org/schema/aop
     http://www.springframework.org/schema/aop/spring-aop.xsd
     http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">

    <!-- 自动扫描 将带有@Conponent 等注解的类的实例，注入到ioc容器中-->
    <context:component-scan base-package="com.atguigu.activemq"/>

    <bean id="jmsFactory" class="org.apache.activemq.pool.PooledConnectionFactory"  destroy-method="stop">
        <property name="connectionFactory">
            <bean class="org.apache.activemq.ActiveMQConnectionFactory">
                <property name="brokerURL" value="tcp://192.168.2.180:61616"></property>
            </bean>
        </property>
        <property name="maxConnections" value="100"></property>
    </bean>

    <!-- 队列目的地 -->
    <bean id="destinationQueue" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg index="0" value="spring-active-queue"></constructor-arg>
    </bean>
    <!--主题-->
    <bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg index="0" value="spring-active-topic"></constructor-arg>
    </bean>

    <!--  jms 的工具类 -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="jmsFactory"/>
        <property name="defaultDestination" ref="destinationTopic"/>
        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>

   <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="jmsFactory"/>
        <property name="destination" ref="destinationTopic"/>
        
        <property name="messageListener" ref="myMessageListener"/>
    </bean>

</beans>

3、队列

//生产者
@Service
public class SpringMQ_Produce {

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext ac =new ClassPathXmlApplicationContext("applicationContext.xml");
        SpringMQ_Produce produce = (SpringMQ_Produce)ac.getBean("springMQ_Produce");
        produce.jmsTemplate.send((sesson)->{
            return sesson.createTextMessage("spring和ActiveMQ的整合 ---> for topic ");
        });

        System.out.println("消息发送到MQ成功！！");
    }

}

// 消费者
@Service
public class SpringMQ_Consumer {

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext ac =new ClassPathXmlApplicationContext("applicationContext.xml");
        SpringMQ_Consumer consumer = (SpringMQ_Consumer)ac.getBean("springMQ_Consumer");

        String message = (String)consumer.jmsTemplate.receiveAndConvert();
        System.out.println("消费者收到消息："+message);

    }
}

4、主题
和上述队列的代码一致，只需修改applicationContext.xml中的

<!--  jms 的工具类 -->
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
    <property name="connectionFactory" ref="jmsFactory"/>
    <property name="defaultDestination" ref="destinationTopic"/>
    <property name="messageConverter">
        <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
    </property>
</bean>

5、在spring中实现消费者不启动，之间通过配置监听完成

编写监听，并加入到spring容器

@Component 
public class MyMessageListener implements MessageListener { 
@Override 
public void onMessage(Message message) { 
if(null!=message&&message instanceof TextMessage){ 
TextMessage textMessage=(TextMessage)message; 
try { 
System.out.println("消费者接收到消息："+ textMessage.getText()); 
} 
catch (JMSException e) { 
e.printStackTrace(); 
} 
}
 } 
}

xml配置监听容器

<bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> 
<property name="connectionFactory" ref="jmsFactory"/> <property name="destination" ref="destinationTopic"/> 
<property name="messageListener" ref="myMessageListener"/> 
</bean>

直接启动消费者：
