原因是用gmail邮件进行发送，需要添加一下参数：

   properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
   properties.setProperty("mail.smtp.socketFactory.fallback", "false"); 
   properties.setProperty("mail.smtp.port", "465"); 
   properties.setProperty("mail.smtp.socketFactory.port", "465");

 

发送Mail实例代码

//检测收件地址合法性
if(toAry == null || toAry.length == 0 || toAry[0] == null || "".equals(toAry[0])){
	if(this.logger.isErrorEnabled()){
		this.logger.error("Recipient found empty while sending a mail,Mail subject is : " + mailSubject);
	}
	return "Recipient is empty";
}
JavaMailSenderImpl javaMailSender = (JavaMailSenderImpl)AppUtil.getBean("mailSender");
		
//检测是否为smtp.gmail.com
if(javaMailSender.getHost().indexOf("smtp.gmail.com") >=0 ){
	Properties properties = javaMailSender.getJavaMailProperties();
	properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
            properties.setProperty("mail.smtp.socketFactory.fallback", "false");

            properties.setProperty("mail.smtp.socketFactory.port", "465");
            javaMailSender.setJavaMailProperties(properties);
}
MimeMessage mimeMessage = javaMailSender.createMimeMessage();
		
try {
	MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, fileAry != null);
	//设置发送者
	mimeMessageHelper.setFrom(from == null ? this.defaultFrom : from);
	//设置接受者
	mimeMessageHelper.setTo(toAry);
	//设置抄送者
	if(cc != null && !"".equals(cc))
		mimeMessageHelper.setCc(cc);
	//设置回复者
	if(replyTo != null && !"".equals(replyTo))
		mimeMessageHelper.setReplyTo(replyTo);
	//邮件主题
	mimeMessageHelper.setSubject(mailSubject);
	//邮件正文
	mimeMessageHelper.setText(templateStr,true);
	//判断资源文件列表是否为空
	if(fileAry != null){
		if(flag){//若为嵌入式资源
			for(int i = 0; i < fileAry.length; i++)
				mimeMessageHelper.addInline(stringAry[i], fileAry[i]);
		}else{

		}
	}
	//发送
javaMailSender.send(mimeMessage);
