Java後台發送郵件

標籤：屬性   address   串連   images   代碼   from   add   mail   sub   

一、實現思路：

1.設定串連參數

2.設定郵件相關屬性

3.發送郵件

二、相關需求：

1.匯入jar包：

2.設定email.properties

mail.smtp.host=smtp.163.commail.smtp.auth=trueuserName[email protected].compassword=asdkahsda

 

二、代碼實現：

public class SendEmail {private static Properties props = null;private static Session session = null;private static MimeMessage message = null;private static Transport transport = null;/** * 配置參數 * @throws IOException * @throws NoSuchProviderException */private static void init() throws IOException, NoSuchProviderException{props = new Properties();//設定設定檔props.load(SendEmail.class.getClassLoader().getResourceAsStream("email.properties"));session = Session.getInstance(props);message = new MimeMessage(session);transport = session.getTransport("smtp");}/** * 發送郵件 * @param toAddress * @param subject * @param sendMessage */public static void sendEmail(String toAddress,String subject,String sendMessage){try {init();session.setDebug(true);//設定寄件者message.setFrom(new InternetAddress(props.getProperty("userName")));//設定收件者message.setRecipient(Message.RecipientType.TO, new InternetAddress(toAddress));//設定郵件主題message.setSubject(subject);//設定郵件內容message.setText(sendMessage);message.saveChanges();transport.connect(props.getProperty("userName"), props.getProperty("password"));transport.sendMessage(message, message.getAllRecipients());              transport.close();} catch (MessagingException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}

 請指教。
