首先下載JavaMail API并確保相關的JAR文件在您的類路徑中。

下面是一個使用Gmail的完整示例。import?java.util.*;import?javax.mail.*;import?javax.mail.internet.*;public?class?Main?{

private?static?String?USER_NAME?=?"*****";??//?GMail?user?name?(just?the?part?before?"@gmail.com")

private?static?String?PASSWORD?=?"********";?//?GMail?password

private?static?String?RECIPIENT?=?"lizard.bill@myschool.edu";

public?static?void?main(String[]?args)?{

String?from?=?USER_NAME;

String?pass?=?PASSWORD;

String[]?to?=?{?RECIPIENT?};?//?list?of?recipient?email?addresses

String?subject?=?"Java?send?mail?example";

String?body?=?"Welcome?to?JavaMail!";

sendFromGMail(from,?pass,?to,?subject,?body);

}

private?static?void?sendFromGMail(String?from,?String?pass,?String[]?to,?String?subject,?String?body)?{

Properties?props?=?System.getProperties();

String?host?=?"smtp.gmail.com";

props.put("mail.smtp.starttls.enable",?"true");

props.put("mail.smtp.host",?host);

props.put("mail.smtp.user",?from);

props.put("mail.smtp.password",?pass);

props.put("mail.smtp.port",?"587");

props.put("mail.smtp.auth",?"true");

Session?session?=?Session.getDefaultInstance(props);

MimeMessage?message?=?new?MimeMessage(session);

try?{

message.setFrom(new?InternetAddress(from));

InternetAddress[]?toAddress?=?new?InternetAddress[to.length];

//?To?get?the?array?of?addresses

for(?int?i?=?0;?i?

toAddress[i]?=?new?InternetAddress(to[i]);

}

for(?int?i?=?0;?i?

message.addRecipient(Message.RecipientType.TO,?toAddress[i]);

}

message.setSubject(subject);

message.setText(body);

Transport?transport?=?session.getTransport("smtp");

transport.connect(host,?from,?pass);

transport.sendMessage(message,?message.getAllRecipients());

transport.close();

}

catch?(AddressException?ae)?{

ae.printStackTrace();

}

catch?(MessagingException?me)?{

me.printStackTrace();

}

}}

自然，您會想在catch塊，而不是像我在上面的示例代碼中所做的那樣打印堆棧跟蹤。(移除catch塊，以查看來自JavaMailAPI的哪個方法調用會拋出異常，這樣您就可以更好地了解如何正確處理它們。)
