{
boolean flag = true;
//建立邮件会话
Properties pro = new Properties();
pro.put("mail.smtp.host","smtp.qq.com");//存储发送邮件java发送邮件代码下载的服务器
pro.put("mail.smtp.auth","true"); //通过服务器验证
Session s =Session.getInstance(pro); //根据属性新建一个邮件会话
//s.setDebug(true);
//由邮件会话新建一个消息对象

//设置邮件
InternetAddress fromAddr = null;
InternetAddress toAddr = null;
try
