用JavaMail的API发送邮件
1、MimeMessage的包装类public class SimpleMessageWraper {private Session session;private MimeMessage mimeMessage;private Multipart multipart = new MimeMultipart();;public Session getSession() {return session;}public MimeMessage getMimeMessage() {return mimeMessage;}private String arrayToString(String[] array){String s = "";if(array != null && array.length > 0){for(int i=0;i<array.length;i++){if(s == ""){s = array.trim();}else{s += "," + array.trim();}}}return s;}public SimpleMessageWraper(Properties props){ session = Session.getInstance(props); session.setDebug(false); mimeMessage = new MimeMessage(session);}public void setFrom(String from)throws MessagingException{mimeMessage.setFrom(new InternetAddress(from)); mimeMessage.saveChanges();}public void setTo(String[] toArray)throws MessagingException{String s = arrayToString(toArray);Address[] addresses = InternetAddress.parse(s);mimeMessage.setRecipients(Message.RecipientType.TO, addresses); mimeMessage.saveChanges();}public void setCc(String[] ccArray)throws MessagingException{String s = arrayToString(ccArray);Address[] addresses = InternetAddress.parse(s);mimeMessage.setRecipients(Message.RecipientType.CC, addresses); mimeMessage.saveChanges();}public void setSubject(String subject)throws MessagingException{mimeMessage.setSubject(subject); mimeMessage.saveChanges();}public void setSentDate(Date date)throws MessagingException{mimeMessage.setSentDate(date); mimeMessage.saveChanges();} public void setText(String text)throws MessagingException{ MimeBodyPart mimeBodyPart = new MimeBodyPart(); mimeBodyPart.setText(text); multipart.addBodyPart(mimeBodyPart); mimeMessage.setContent(multipart); mimeMessage.saveChanges(); } public void addAttactment(File file)throws MessagingException,UnsupportedEncodingException{ if(file == null) return; MimeBodyPart mimeBodyPart = new MimeBodyPart(); mimeBodyPart.setFileName(MimeUtility.encodeText(file.getName(), "GBK", "B")); //对邮件头采用base64方式编码 mimeBodyPart.setDataHandler(new DataHandler(new FileDataSource(file))); multipart.addBodyPart(mimeBodyPart); mimeMessage.setContent(multipart); mimeMessage.saveChanges(); }}
2、发送邮件的工具类
public class SimpleMailFactory {private static SimpleMailConfig simpleMailConfig = null;private static Properties props = null;static{ //取得包含邮件配置信息的bean对象simpleMailConfig = (SimpleMailConfig)SpringContextUtil.getBean(Constants.simpleMailConfigBeanName);props = new Properties(); props.put("mail.smtp.host", simpleMailConfig.getHost()); props.put("mail.smtp.auth", simpleMailConfig.getAuth());}/** * 功能：取得邮件消息对象的包装器 */public static SimpleMessageWraper getSimpleMessageWraper(){return new SimpleMessageWraper(props);}/** * 功能：邮件发送 */public static void send(SimpleMessageWraper messageWraper)throws Exception{MimeMessage mimeMessage = messageWraper.getMimeMessage(); Transport transport = messageWraper.getSession().getTransport(simpleMailConfig.getTransport()); transport.connect(simpleMailConfig.getHost(), simpleMailConfig.getUsername(), simpleMailConfig.getPassword()); transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients()); transport.close(); }}
3、包含邮件配置信息的bean对象
<bean id="simpleMailConfig" class="com.cjm.common.mail.SimpleMailConfig"><property name="host" value="smtp.163.com"/><property name="username" value="uid"/><property name="password" value="pwd"/><property name="auth" value="true"/></bean>
4、实例代码
SimpleMessageWraper w1 = SimpleMailFactory.getSimpleMessageWraper();w1.setFrom("ServerMailAddress@163.com");w1.setTo(new String[]{"TargetAddress@139.com"});w1.setSubject("标题");w1.setText("邮件内容");w1.addAttactment(new File("c:\\附件.txt"));SimpleMailFactory.send(w1);
