消息驱动bean的使用

1. 通过buildPath把jboss中client中的所有jar包导入
2. 用于接收消息的类

   package revieve;
   
   import javax.ejb.ActivationConfigProperty;
   import javax.ejb.MessageDriven;
   import javax.jms.JMSException;
   import javax.jms.Message;
   import javax.jms.MessageListener;
   import javax.jms.TextMessage;
   
   @MessageDriven(activationConfig = {
   		@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
   		@ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/myQueue"),
   		@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge") })
   public class recieve implements MessageListener {
   
   	@Override
   	public void onMessage(Message arg0) {
   		// TODO Auto-generated method stub
   		TextMessage tm = (TextMessage) arg0;
   		try {
   			System.out.println(tm.getText());
   		} catch (JMSException e) {
   			// TODO Auto-generated catch block
   			e.printStackTrace();
   		}
   	}
   
   }
   

   @MessageDriven中的destination propertyValue自定义

3. 发送消息的类

   package send;
   
   import javax.jms.ConnectionFactory;
   import javax.jms.Destination;
   import javax.jms.JMSException;
   import javax.jms.MessageProducer;
   import javax.jms.QueueConnection;
   import javax.jms.QueueSession;
   import javax.jms.TextMessage;
   import javax.naming.Context;
   import javax.naming.InitialContext;
   import javax.naming.NamingException;
   
   public class sender {
   
   	/**
   	 * @param args
   	 * @throws NamingException
   	 * @throws JMSException
   	 */
   	public static void main(String[] args) throws NamingException, JMSException {
   		// TODO Auto-generated method stub
   
   		Context ctx = new InitialContext();
   		ConnectionFactory cf = (ConnectionFactory) ctx
   				.lookup("ConnectionFactory");
   		QueueConnection qc = (QueueConnection) cf.createConnection();
   		QueueSession session = qc.createQueueSession(false,
   				QueueSession.AUTO_ACKNOWLEDGE);
   		Destination destination = (Destination) ctx.lookup("queue/myQueue");
   		MessageProducer producer = session.createProducer(destination);
   		TextMessage tm = session.createTextMessage("Hello,消息驱动bean!");
   		producer.send(tm);
   		System.out.println("Test passes!");
   		session.close();
   		qc.close();
   	}
   
   }
   

   ctx.lookup()查找的destination需要与上文中的一致

4. 编写build.xml文件

   <?xml version="1.0" encoding="UTF-8"?>
   
   <project name="message" default="ejbjar" basedir=".">
     
     <property name="src.dir" value="${basedir}\src" />
   	<property environment="env" />
   	<property name="jboss.home" value="${env.JBOSS_HOME}" />
   	<property name="jboss.server.config" value="default" />
   	<property name="build.dir" value="${basedir}\build" />
   
   	
   	<path id="build.classpath">
   		<fileset dir="${jboss.home}\client">
   			<include name="*.jar" />			
   		</fileset>
   		<pathelement location="${build.dir}" />
   	</path>
   
   	
   	<target name="prepare">
   		<delete dir="${build.dir}" />
   		<mkdir dir="${build.dir}" />
   	</target>
   
   	
   	<target name="compile" depends="prepare" description="编绎">
   		<javac srcdir="${src.dir}" destdir="${build.dir}" debug="on" encoding="UTF-8">
   			
   			<classpath refid="build.classpath" />
   		</javac>
   	</target>
   
   	<target name="ejbjar" depends="compile" description="创建EJB发布包">
   		<jar jarfile="${basedir}\${ant.project.name}.jar">
   			<fileset dir="${build.dir}">
   				<include name="**/*.class" />
   			</fileset>
   		</jar>
   	</target>
   
   	<target name="deploy" depends="ejbjar" description="发布EJB">
   		<copy file="${basedir}\${ant.project.name}.jar" todir="${jboss.home}\server\${jboss.server.config}\deploy" />
   	</target>
   
   	
   	<target name="undeploy" description="卸载EJB">
   		<delete file="${jboss.home}\server\${jboss.server.config}\deploy\${ant.project.name}.jar" />
   	</target>
   
   </project>
   

5. 打包成jar，放到 jboss/server/default/deploy 目录下（jboss5）

6. 把刚刚的 jar 包导入项目中

7. 编写 **-service.xml 文件（-前面的名字自定义）（jboss会将此类文件当成服务发布）

   <?xml version="1.0" encoding="UTF-8"?>
   <server>  
     <mbean code="org.jboss.mq.server.jmx.Queue"
            name="jboss.mq.destination:service=Queue,name=myQueue">
       <attribute name="JNDIName">queue/myQueue </attribute>   
       <depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends>
     </mbean>
   </server>

   jndiName就是上面ctx.lookup()查找的内容，必须一致

8. 在类中加入jndi.properties文件（或者测试类中初始上下文的时候写进去）

   java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
   java.naming.provider.url=localhost\:1099

9. 通过send类发送一个消息，如果部署成功，会自动输出
