// Step 1: Configure the mail session
String from = "******"; //发送邮件的账号
String password = "******"; //Password
String smtpHost = "smtp.163.com"; //SMTP服务器
java.util.Properties props = new java.util.Properties();
props.setProperty("mail.smtp.auth", "true");// 指定是否需要SMTP验证
props.setProperty("mail.smtp.host", smtpHost);// 指定SMTP服务器
props.put("mail.transport.protocol", "smtp");
Session mailSession = Session.getDefaultInstance(props);
mailSession.setDebug(false);// 是否在控制台显示debug信息
// Step 2: Construct the message
System.out.println("Constructing message - from=" + from + " to=" + to);
InternetAddress fromAddress = new InternetAddress(from);
InternetAddress toAddress = new InternetAddress(to);
MimeMessage testMessage = new MimeMessage(mailSession);
testMessage.setFrom(fromAddress);
testMessage.addRecipient(javax.mail.Message.RecipientType.TO, toAddress);
testMessage.setSentDate(new java.util.Date());
testMessage.setSubject(MimeUtility.encodeText(subject, "gb2312", "B"));
testMessage.setContent(messageText, "text/html;charset=gb2312");
System.out.println("Message constructed");
// Step 3: Now send the message
Transport transport = mailSession.getTransport("smtp");
transport.connect(smtpHost, from, password);
transport.sendMessage(testMessage, testMessage.getAllRecipients());
