發送郵件的簡單實現 加附件不成功的話就是遭到了系統的退信

Properties props=new Properties();

props.setProperty("mail.host", "smtp.126.com");
props.setProperty("mail.smtp.auth","true");

Authenticator auth=new Authenticator(){

 @Override
protected PasswordAuthentication getPasswordAuthentication() {

 
 
return new PasswordAuthentication("junfeng8668","zjq1254");


};





};
Session session=Session.getInstance(props, auth);



//2.創建mimemessage

MimeMessage  msg=new MimeMessage(session);

msg.setFrom(new InternetAddress("[email protected]"));

msg.setRecipients(RecipientType.TO,"[email protected]");
// msg.setRecipients(RecipientType.CC,"[email protected]");
// msg.setRecipients(RecipientType.BCC,"[email protected]");

msg.setSubject("這是來自雷雨的測試郵件");
// msg.setContent("這就是一封測試郵件","text/html;charset=utf-8");
////////////////////
///// 我們來發送帶有附件郵件
MimeMultipart list=new MimeMultipart();
//
//
// //創建mimebodypart
// MimeBodyPart part=new MimeBodyPart();
////
// part.setContent("這是一封包含附件的郵件","text/html;charset=utf-8");
// //把主體部件添加到集合中
//
// list.addBodyPart(part);


MimeBodyPart pa=new MimeBodyPart();
//
pa.attachFile(new File("F:/baibing.jpg"));//設置附件內容
//
//
// //其中有處理中文亂碼的地方
pa.setFileName(MimeUtility.encodeText("美女.jpg"));
//




list.addBodyPart(pa);

msg.setContent(list);




Transport.send(msg);
