项目需要用java实现自动发邮件，包含邮件标题，正文和附件，
网上搜索了一下拿到的实例都无法满足需求，为了方便以后查阅也方便他人查阅记录如下
实例如下：
1.如果遇到 class not found问题请删除 myeclipse\Common\plugins\com.genuitec.eclipse.j2eedt.core_10.0.0.me201110301321\data\libraryset\EE_5\javaee.jar
2.可能有人会遇到设置附件后邮件正文就没有了，为此你需要单独new 一个 object，
//content part
BodyPart messageContentBodyPart = new MimeBodyPart();
messageContentBodyPart.setContent(mailInfo.getContent(), "text/html; charset=utf-8");
multipart.addBodyPart(messageContentBodyPart);
