JMS外发邮件(EJB)

阅读更多

环境:jdk1.6/jboss4.2

 

前提:一些基本的EJB知识

 

1. 在jboss-4.2.2.GA\server\default\deploy目录下,新建simple-jms-service.xml文件,定义消息存放地址,

 

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

 

部署成功后在jmx-console页面上可以看到刚部署的queue/simplejms。

 

2. 修改同一目录下mail-service.xml文件

 

<?xml version="1.0" encoding="UTF-8"?>
<!-- $Id: mail-service.xml 62349 2007-04-15 16:48:15Z dimitris@jboss.org $ -->
<server>

  <!-- ==================================================================== -->
  <!-- Mail Connection Factory                                              -->
  <!-- ==================================================================== -->

  <mbean code="org.jboss.mail.MailService"
         name="jboss:service=Mail">
    <attribute name="JNDIName">java:/Mail</attribute>
    <attribute name="User">你邮件用户名</attribute>
    <attribute name="Password">邮件密码</attribute>
    <attribute name="Configuration">
      <!-- A test configuration -->
      <configuration>
        <!-- Change to your mail server prototocol -->
        <property name="mail.store.protocol" value="pop3"/>
        <property name="mail.transport.protocol" value="smtp"/>

        <!-- Change to the user who will receive mail  -->
        <property name="mail.user" value="nobody"/>

        <!-- Change to the mail server  -->
        <property name="mail.pop3.host" value="pop3.163.com"/>

        <!-- Change to the SMTP gateway server -->
        <property name="mail.smtp.host" value="smtp.163.com"/>
		
		<!-- Add to authorize -->
		<property name="mail.smtp.auth" value="true"/>
        
        <!-- The mail server port -->
        <property name="mail.smtp.port" value="25"/>
        
        <!-- Change to the address mail will be from  -->
        <property name="mail.from" value="nobody@163.com"/>

        <!-- Enable debugging output from the javamail classes -->
        <property name="mail.debug" value="false"/>
      </configuration>
    </attribute>
    <depends>jboss:service=Naming</depends>
  </mbean>

</server>
 

 

3. 编写消息消费者(一个MDB),不是很严密,没有验证为空什么的。

 

package com.xxx.ejb3.mdb;

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.MapMessage;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.naming.Context;
import javax.naming.InitialContext;

@MessageDriven(activationConfig = {
		@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
		@ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/simplejms"),
		@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto_acknowledge") })
public class NetworkMessageBean implements MessageListener {

	@Override
	public void onMessage(Message msg) {
		try {
			if (msg instanceof MapMessage) {

				MapMessage mmsg = (MapMessage) msg;
				InternetAddress from = new InternetAddress(mmsg
						.getString("from"));
				InternetAddress to = new InternetAddress(mmsg.getString("to"));
				String subject = mmsg.getString("subject");
				String content = mmsg.getString("content");

				System.out
						.println("message is:" + "\nfrom: " + from + "\nto: "
								+ to + "\nsuject: " + subject + "\ncontent: "
								+ content);

				Context ctx = new InitialContext();
				Session session = (Session) ctx.lookup("java:/Mail");

				javax.mail.Message actualMsg = new MimeMessage(session);

				actualMsg.setFrom(from);
				actualMsg.setRecipient(javax.mail.Message.RecipientType.TO, to);
				actualMsg.setSubject(subject);
				actualMsg.setText(content);

				Transport.send(actualMsg);

			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
 

 

导出成jar包,部署到jboss-4.2.2.GA\server\default\deploy目录。

 

4. 编写消息生产者/消息发送者,这里使用一个普通的Java Application在main方法中完成消息发送。

 

package com.xxx.ejb3.client;

import javax.jms.Destination;
import javax.jms.MapMessage;
import javax.jms.MessageProducer;
import javax.jms.Queue;
import javax.jms.QueueConnection;
import javax.jms.QueueConnectionFactory;
import javax.jms.QueueSession;
import javax.naming.Context;

import com.xxx.ejb3.util.ContextUtil;

public class NetworkMessageProducer {

	public static void main(String[] args) {

		QueueConnection conn = null;
		QueueSession session = null;

		try {
			Context ctx = ContextUtil.getContext();
			QueueConnectionFactory factory = (QueueConnectionFactory) ctx
					.lookup("QueueConnectionFactory");
			conn = factory.createQueueConnection();
			session = conn.createQueueSession(false,
					QueueSession.AUTO_ACKNOWLEDGE);

			Destination destination = (Queue) ctx.lookup("queue/simplejms");
			MessageProducer producer = session.createProducer(destination);

			MapMessage msg = session.createMapMessage();
			msg.setString("from", "jwu@iteye.com"); 
			msg.setString("to", "jwu@qq.com");
			String subject = "no subject/无主题";
			String content = "Hi, this is a mail sent by JMS from a piece of code./支持中文吗";
			msg.setString("subject", subject);
			msg.setString("content", content);

			System.out.println("start sending message...");
			producer.send(msg);
			System.out.println("finish sending message.");

		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			try {
				session.close();
				conn.close();
			} catch (Exception e) {
				e.printStackTrace();
			}
		}

	}
}
 

 

在使用这个类时,需要导入jbossall-client.jar和上面自己导出的jar包。

这里使用了一个工具类:ContextUtil.java

 

package com.xxx.ejb3.util;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class ContextUtil {

	private static Context context;

	static {
		try {
			context = new InitialContext();
		} catch (NamingException e) {
			e.printStackTrace();
		}
	}

	public static Context getContext() {
		return context;
	}
}
