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

<?xml version="1.0" encoding="UTF-8"?><beansxmlns="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.xsdhttp://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

<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">  <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>  <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>  <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>  <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>

(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;}}
