JODD mail 发送带附件的邮件

 最近编写了邮件功能的代码， 在附件位置可以将附件位置传入，但是为了防止位置找不到，这里我用传入了流，但是这样有弊端，多附件的时候不容易拓展。。。。

import cn.cmschina.article.dto.EmailInfo;
import jodd.mail.Email;
import jodd.mail.EmailAttachment;
import jodd.mail.SendMailSession;
import jodd.mail.SmtpServer;
import jodd.mail.att.FileAttachment;
import jodd.petite.meta.PetiteBean;

/**

@PetiteBean("emailSendUtil")
public class EmailSendUtil {

	private String smtpHost = null;
	
	public String sendEmailTo(EmailInfo info) throws Exception{
		String log = "";
		try {
			String user = info.getFrom().split("@")[0];
			@SuppressWarnings("rawtypes")
			SmtpServer smtpServer = SmtpServer.create(smtpHost,25)
		                .authenticateWith(user, info.getPassword());

		    Email email = Email.create()
		                .from(info.getFrom())
		                .subject(info.getSubject());
		   log +="服务器地址："+ smtpHost;
	        if (null != info.getText()) {
	        	//正文
	        	 email.addText(info.getText());
			}
	        
	        //收件人
	        email.to(info.getTo());
	        if (null != info.getFile() && null != info.getFilename()) {
	        	String filename = info.getFilename();
		        //截取文件名
		        //String filename = filepath.substring(filepath.lastIndexOf("/")+1);
		        //截取文件类型
		        String pdf = filename.substring(filename.indexOf(".")+1);
		        EmailAttachment attachment = new FileAttachment(
		                info.getFile(),filename,pdf);
		        //设置附件
		        email.attach(attachment);
			}
	        
	        log += "Eamil对象："+email.toString();
	        SendMailSession session = smtpServer.createSession();
	        
	        session.open();
	        session.sendMail(email);
	        session.close();
	        return log;
		} catch (Exception e) {
			e.printStackTrace();
			log+="异常信息："+e;
			throw new Exception(log);
		}
	}
}
