System.out.println(props);
Session session = Session.getDefaultInstance(props,auth);
//设置session,和邮件服务器进行通讯
MimeMessage message = new MimeMessage(session);
message.setContent("Hello","text/plain");//设置邮件格式
message.setSubject(mail_subject);//设置邮件主题
message.setText(mail_body);//设置邮件内容
message.setHeader(mail_head_name, mail_head_value);//设置邮件标题
message.setSentDate(new Date());//设置邮件发送时期
Address address = new InternetAddress(mail_from,personalName);
message.setFrom(address);//设置邮件发送者的地址
Address toaddress = new InternetAddress(mail_to);//设置邮件接收者的地址
message.addRecipient(Message.RecipientType.TO,toaddress);
System.out.println(message);
Transport.send(message);
System.out.println("Send Mail Ok!");
} catch (Exception e) {
e.printStackTrace();
}
//return flag;
