使用javamail進行郵件發送

// 在javax.mail包中的類，需要引入的。 import javax.activation.DataHandler; import javax.activation.DataSource; import javax.activation.FileDataSource; import javax.activation.URLDataSource;import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; import javax.mail.internet.MimeUtility;import javax.mail.*;

看看測試方法：

public static void main(String args[]) throws Exception {String strAttachmentFileName = "project.txt";String fileAttachment = "http://....../project.txt";String from = "from@mail.com.cn";String to = "to@mail.com.cn";Session session1;Properties properties1 = System.getProperties();properties1.setProperty("mail.transport.protocol", "smtp");properties1.setProperty("mail.smtp.auth", "true");properties1.setProperty("mail.smtp.host", "smtp.exmail.qq.com");session1 = Session.getInstance(properties1, new Authenticator() {protected PasswordAuthentication getPasswordAuthentication() {// 注冊的可以發送的郵件賬號return new PasswordAuthentication("postmaster@mail.com.cn","password"); }});// Define messageMimeMessage message = new MimeMessage(session1);message.setFrom(new InternetAddress(from));message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));message.setSubject("Hello JavaMail Attachment");Multipart multipart = new MimeMultipart();// create the message partMimeBodyPart messageBodyPart = new MimeBodyPart();// fill messagemessageBodyPart.setText("<h2>Hello</h2><p>This is the content for this email.</p><p>中文內容測試</p>","utf-8", "html");multipart.addBodyPart(messageBodyPart);// Part two is attachment// 如果有多個，多次操作添加attaMimeBodyPart messageBodyPart1 = new MimeBodyPart();URL fileURL = new URL(fileAttachment);DataSource source = new URLDataSource(fileURL);messageBodyPart1.setDataHandler(new DataHandler(source));messageBodyPart1.setFileName(strAttachmentFileName);multipart.addBodyPart(messageBodyPart1);// Put parts in messagemessage.setContent(multipart);// Send the messageTransport.send(message);}

稍后到郵箱檢查，可以看到發送的郵件了。
