第一次做发邮件功能，

遇到一个javamail的问题：

javax.mail.SendFailedException: Invalid Addresses

是在收件地址不对或不存在的情况下出现的，并且那些对的地址也不能发送出去；解决方案如下，捕获处理并重发

try\{

//发送代码

\}catch (MailSendException se) \{  
            Exception\[\] messageExceptions = se.getMessageExceptions();  
            SendFailedException sendFail;  
            try \{  
                sendFail = (SendFailedException) messageExceptions\[0\];  
            \} catch (ClassCastException e) \{  
                LOGGER.error("class cast exception:\[\{\}\]", e.getMessage());  
                return;  
            \}  
            LOGGER.error("send mail eerror,the invalid mail address:\{\}", sendFail.getInvalidAddresses());  
            Address\[\] address = sendFail.getValidUnsentAddresses();  
            if (null == address) \{  
                  
                return;  
            \}  
            String\[\] validMails = new String\[address.length\];  
            for (int i = 0; i < address.length; i++) \{  
                validMails\[i\] = String.valueOf(address\[i\]);  
            \}  
            try \{  
                message.setTo(validMails);   
                mailSender.send(message); //重新发送  
            \} catch (MessagingException e) \{  
                LOGGER.error("create MimeMessage exception.", e);  
                throw new ServerLayerException("-1");  
            \}  
        \} catch (MessagingException e) \{  
            LOGGER.error("create MimeMessage exception.", e);  
            throw new ServerLayerException("-2");  
        \}
