ActiveMQ5.4.2+Spring2.5实现异步邮件

(1)applicationContext.xml 添加命名空间xmlns:amq及对应的schemaLocation

<?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:amq="http://activemq.apache.org/schema/core" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core-5.4.2.xsd ">

 (2)applicationContext.xml中JMS的配置

 

<!-- JMS START --> <amq:broker useJmx="false" persistent="false"> <amq:transportConnectors> <amq:transportConnector uri="tcp://localhost:0"></amq:transportConnector> </amq:transportConnectors> </amq:broker> <bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="vm://localhost" /> </bean> <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue"> <constructor-arg value="UserEmail.queue" /> </bean> <bean id="myJmsTemplate" class="org.springframework.jms.core.JmsTemplate"> <property name="connectionFactory"> <!-- lets wrap in a pool to avoid creating a connection per send --> <bean class="org.springframework.jms.connection.SingleConnectionFactory"> <property name="targetConnectionFactory"> <ref local="jmsConnectionFactory" /> </property> </bean> </property> </bean> <bean id="emailUtil" class="org.ouc.webNewTech.common.EmailUtil"></bean> <bean id="userMessageConsumer" class="org.ouc.webNewTech.common.EmailReceiver"> <property name="sysInterface"> <ref local="SysInterface"/> </property> <property name="emailUtil"> <ref local="emailUtil"/> </property> </bean> <!-- a sample POJO consumer --> <bean id="messageListener" class="org.springframework.jms.listener.adapter.MessageListenerAdapter"> <constructor-arg ref="userMessageConsumer"></constructor-arg> <property name="defaultListenerMethod" value="handleMessage"></property> <property name="messageConverter" ref="userMessageConverter"></property> </bean> <bean id="userMessageConverter" class="org.ouc.webNewTech.common.EmailConverter"></bean> <bean id="taskExecutor" class="org.springframework.core.task.SimpleAsyncTaskExecutor"></bean> <!-- this is the message listener container --> <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="concurrentConsumers" value="1"></property> <property name="maxConcurrentConsumers" value="1"></property> <property name="connectionFactory" ref="jmsConnectionFactory"></property> <property name="destination" ref="queueDestination"></property> <property name="messageListener" ref="messageListener"></property> <property name="receiveTimeout" value="10000"></property> <property name="taskExecutor" ref="taskExecutor"></property> <property name="cacheLevel" value="0"></property> <property name="cacheLevelName" value="CACHE_CONNECTION"></property> </bean> <!-- a sample POJO which uses a Spring JmsTemplate --> <bean id="producer" class="org.ouc.webNewTech.common.EmailSender"> <property name="jmsTemplate"> <ref bean="myJmsTemplate"></ref> </property> <property name="destination"> <ref bean="queueDestination" /> </property> </bean> <!-- JMS END -->  

 

(3) 邮件的发送者

public class EmailSender { private JmsTemplate jmsTemplate; private Destination destination; public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } public void setDestination(Destination destination) { this.destination = destination; } public void Send(UserEmail userEmail){ jmsTemplate.convertAndSend(destination,userEmail); } } 

(4)邮件转换

 

public class EmailConverter implements MessageConverter{ public Object fromMessage(Message message) throws JMSException, MessageConversionException { if(message instanceof ObjectMessage){ ObjectMessage oMsg=(ObjectMessage)message; if(oMsg instanceof ActiveMQObjectMessage){ ActiveMQObjectMessage aMsg=(ActiveMQObjectMessage) oMsg; UserEmail userEmail=(UserEmail) aMsg.getObject(); return userEmail; } } return null; } public Message toMessage(Object obj, Session session) throws JMSException, MessageConversionException { if(obj instanceof UserEmail){ ActiveMQObjectMessage msg=(ActiveMQObjectMessage) session.createObjectMessage(); msg.setObject((UserEmail)obj); return msg; } return null; } } 

(5)邮件的接受者，这里指的是通过jms接收邮件，真正的邮件发送是在这里进行的。

public class EmailReceiver{ private static Logger logger = Logger.getLogger(EmailReceiver.class); private SysInterface sysInterface; private EmailUtil emailUtil; public EmailUtil getEmailUtil() { return emailUtil; } public void setEmailUtil(EmailUtil emailUtil) { this.emailUtil = emailUtil; } public SysInterface getSysInterface() { return sysInterface; } public void setSysInterface(SysInterface sysInterface) { this.sysInterface = sysInterface; } public void handleMessage(UserEmail userEmail) throws JMSException, SysEmailNotSetException{ Sysemail sysemail=sysInterface.getSysEmail(); if(sysemail==null){ throw new SysEmailNotSetException(); } emailUtil.SendMail(sysemail.getEmail(), userEmail.getUserEmail(), sysemail.getEmail(), sysemail.getEmailpass(), userEmail.getTitle(), userEmail.getMessage()); logger.info("Sended a email:" +userEmail.getUserEmail()+userEmail.getUserEmail()+userEmail.getMessage()); } } 

(6)发送邮件的工具类

public class EmailUtil { private static Logger log = Logger.getLogger(EmailUtil.class); private static final String SMTP_PORT = "465"; private static final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory"; /** * 发送电子邮件,支持gmail * @param fromEmail * @param toEmail * @param userName * @param password * @param subject * @param Message */ public void SendMail(String fromEmail,String toEmail, String userName,String password, String subject,String Message){ JavaMailSenderImpl senderImpl = new JavaMailSenderImpl(); String host=getHost(fromEmail); senderImpl.setHost(host); senderImpl.setUsername(userName); senderImpl.setPassword(password); Properties prop = new Properties(); if(host.equalsIgnoreCase("smtp.gmail.com")){ prop.setProperty("mail.smtp.port", SMTP_PORT); prop.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY); prop.setProperty("mail.smtp.socketFactory.port", SMTP_PORT); prop.setProperty("mail.smtp.socketFactory.fallback", "false"); } prop.setProperty("mail.smtp.auth","true"); senderImpl.setJavaMailProperties(prop); SimpleMailMessage mailMessage = new SimpleMailMessage(); mailMessage.setTo(toEmail); mailMessage.setFrom(fromEmail); mailMessage.setSubject(subject); mailMessage.setText(Message); try { senderImpl.send(mailMessage); log.debug("Email send succeed"); } catch(Exception e) { log.debug("Email send fail"); e.printStackTrace(); } } private String getHost(String fromEmail) { int at=fromEmail.indexOf("@"); String tmpStr=fromEmail.substring(at+1); String host="smtp."+tmpStr; return host; } }
