JavaWeb傳送郵件(不包含附件)

使用該功能之前要先開啟郵箱的pop3/smtp功能,具體方法自己去百度。
1.使用的jar包
點選下載
2.後端程式碼

	public static void sendCode(String e_mail) {e_mail需要傳送的郵箱地址
		Properties pro = new Properties();
	      pro.setProperty("mail.host","smtp.qq.com");//qq郵箱為smtp.qq.com 163郵箱為smtp.163.com
	      pro.setProperty("mail.transport.protocol","smtp");
	      pro.setProperty("mail.smtp.auth","true");
          Session session = Session.getInstance(pro);
//          session.setDebug(true);//開啟Debug,可以看到傳送郵件資訊
          Transport ts=null;
          try {
			 ts = session.getTransport();
			 ts.connect(“smtp.xx.com”,埠號(qq郵箱一般為587,163郵箱為25),“郵箱賬號”,“授權碼”);
			 Message message = creatEmail(session,e_mail);
			 ts.sendMessage(message, message.getAllRecipients());//傳送郵件
		} catch (NoSuchProviderException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (MessagingException e) {
			SendCodeEmail.setMessage("郵件傳送失敗!");
			e.printStackTrace();
		}finally {
			try {
				if(ts!=null)ts.close();
			} catch (MessagingException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
          
		
	}
	private static MimeMessage creatEmail(Session sion,String e_mail) {//建立郵件
		MimeMessage message = new MimeMessage(sion);
		try {
			message.setFrom(new InternetAddress(從哪裡傳送的地址(
[email protected]
))); message.setRecipient(Message.RecipientType.TO, new InternetAddress(e_mail));//傳送到哪裡 message.setSubject(“主題”);//設定主題 message.setContent(“內容”,"text/html;charset=UTF-8");//設定內容 } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } return message; }
