mail.smtp.port=465
mail.smtp.auth=true
mail.smtp.timeout=25000

mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.smtp.socketFactory.port=465
mail.smtp.socketFactory.fallback=false
mail.recipient.cc=[e-mail]

2.MailUtil.java

@Component
public class MailUtil implements InitializingBean 

	@Autowired
	private AppConfig appConfig;
	
	private static final String SMTP = "smtp";
	private static final String CONTENT_TYPE = "text/html;charset=utf-8";
	private static final List<String> CC = new ArrayList<String>();
	
	private static final Logger logger = Logger.getLogger(MailUtil.class);
	
	public void sendMail(List<String> toList, List<String> cc, String subject, String body)
			throws AddressException, MessagingException 
		Properties props = System.getProperties();
		props.put("mail.smtp.ssl.enable", appConfig.getMailSsl());
		props.put("mail.smtp.host", appConfig.getMailHost());
		props.put("mail.smtp.user", appConfig.getMailUser());
		props.put("mail.smtp.password", appConfig.getMailPassword());
		props.put("mail.smtp.port", appConfig.getMailPort());
		props.put("mail.smtp.auth", appConfig.getMailAuth());

		Session session = Session.getDefaultInstance(props);
		MimeMessage message = new MimeMessage(session);
		message.setFrom(new InternetAddress(appConfig.getMailUser()));	
		logger.info("mail subject : " + subject);	
		List<String> to = new ArrayList<String>();	
		for (int i = 0; i < toList.size(); i++) //去重
			String tempMail = toList.get(i);
			logger.info("toList mail i = " + i + " : " + tempMail);
			if(!to.contains(tempMail))
				to.add(tempMail);
			
			
		
		
		logger.info("after removing the repeat mail, to list size: " + to.size());
		
		//20160202 in product 暂时注释掉 将收件人替换为开发者自己 正式环境下去掉注释
		for (int i = 0; i < to.size(); i++) 
			message.addRecipient(Message.RecipientType.TO, new InternetAddress(to.get(i)));
		
		
		if (cc != null) 
			for (int i = 0; i < cc.size(); i++) 
				message.addRecipient(Message.RecipientType.CC, new InternetAddress(cc.get(i)));
			
		
		
		//没什么用  注释掉
		/*for (int i = 0; i < CC.size(); i++) 
			message.addRecipient(Message.RecipientType.CC, new InternetAddress(CC.get(i)));
		*/
				
		//20160202 in develop 暂时加上将收件人替换为开发者自己 正式环境下注释掉
		//message.addRecipient(Message.RecipientType.TO, new InternetAddress("[e-mail]"));
		//message.addRecipient(Message.RecipientType.TO, new InternetAddress(Constants.ADMIN_EMAIL));
			
		message.setSubject(subject);
		message.setContent(body, CONTENT_TYPE);
			
		Transport transport = session.getTransport(SMTP);
		transport.connect(appConfig.getMailHost(), appConfig.getMailUser(), appConfig.getMailPassword());
		transport.sendMessage(message, message.getAllRecipients());
		transport.close();
	

	@Override
	public void afterPropertiesSet() throws Exception 
		// TODO Auto-generated method stub
		if (!Strings.isNullOrEmpty(appConfig.getMailCc())) 
			String []cc = appConfig.getMailCc().split(";");
			for (int i = 0; i < cc.length; i++) 
				CC.add(cc[i].trim());
			
		
	

3.AppConfig.java(将properties中的属性映射到bean中)

	private String mailTimeout;
	@Value("$mail.smtp.ssl.enable")
	private String mailSsl;
	@Value("$mail.recipient.cc")
	private String mailCc;
		
	public String getMailHost() 
		return mailHost;
	

	public void setMailHost(String mailHost) 
		this.mailHost = mailHost;
	

	public String getMailUser()

	//判断是在开发模式还是生产模式
	public boolean isInDevelopMode() 
		if (runMode.compareTo(DEV_MODE) == 0) 
			return true;
		
		return false;
	

	public boolean isInProductionMode()

	public String getWorkDirPath() 
		return workDirPath;
	
	public int getHttpPort()
