1. 调用邮件的服务为一个定时任务,定时扫描指定文件,若存在待发送的邮件,则以javaMail的方式调用邮件服务,调用示例如下(发件人邮箱SMTP服务器地址:mail.cec.com.cn):

       /**
        * JavaMail 版本: 1.6.0
        * JDK 版本: JDK 1.7 以上(必须)
        */
       public class sendMailService {
       	/**
       	 * 
       	 * @param myEmailAccount      发件人邮箱账号
       	 * @param myEmailPassword	     发件人邮箱密码
       	 * @param myEmailSMTPHost     发件人邮箱SMTP服务器地址
       	 * @param mainSendNameAccounts  收件人主送名称及账号
       	 * @param copySendNameAccounts   收件人抄送名称及账号
       	 * @param secretSendNameAccounts 收件人暗送名称及账号	
       	 * @param sendMsg      发送邮件主体信息
       	 * @return
       	 */
           public static String sendMail(String myEmailAccount, String myEmailPassword,String senderName,String myEmailSMTPHost,Map<String, String> mainSendNameAccounts,Map<String, String> copySendNameAccounts,Map<String, String> secretSendNameAccounts,Map sendMsg)throws Exception {
           	 Properties props = new Properties();                    // 参数配置
                props.setProperty("mail.transport.protocol", "smtp");   // 使用的协议(JavaMail规范要求)
                props.setProperty("mail.smtp.host", myEmailSMTPHost);   // 发件人的邮箱的 SMTP 服务器地址
                props.setProperty("mail.smtp.auth", "false");            // 需要请求认证
                // 2. 根据配置创建会话对象, 用于和邮件服务器交互
                Session session = Session.getInstance(props);
                session.setDebug(true); //开启日志
       		 // 3. 创建一封邮件
                MimeMessage message;
       		 message = createMimeMessage(session, myEmailAccount, senderName,mainSendNameAccounts,copySendNameAccounts,secretSendNameAccounts,sendMsg);
       		 // 4. 根据 Session 获取邮件传输对象
                Transport transport = session.getTransport();
                // 5. 使用 邮箱账号 和 密码 连接邮件服务器, 这里认证的邮箱必须与 message 中的发件人邮箱一致, 否则报错
                transport.connect(myEmailAccount, myEmailPassword);
                // 6. 发送邮件, 发到所有的收件地址, message.getAllRecipients() 获取到的是在创建邮件对象时添加的所有收件人, 抄送人, 密送人
                transport.sendMessage(message, message.getAllRecipients());
                transport.close();
                return Action.SUCCESS;
       	}
