在jsp中发送email 时间：2004/11/7 3:39:00来源：本站整理作者：蓝点我要评论(0): 在jsp中发送email

一、我们可以通过任何支持sun规范中的sun.net.smtp包的JSP引擎(如JSWDK)发送mail。

(警告:使用内置的internal Sun规范包，这将影响到你的jsp程序的可移植性。)

以下scriptlet利用SmtpClient类在jsp文件中发送email。

二、 JavaMail是官方的 Java mail API，可参考 http://java.sun.com/products/javamail/。虽然该API比 sun.net.smtp.SmtpClient更丰富或者说更复杂，但它是可移植的。这里重新创建了一个 MailSender类，它包含了 JavaMail API。如下所示：

// ms_ prefix is for MailSender class variables

// str prefix is for String

// astr prefix is for array of Strings

// strbuf prefix is for StringBuffers, etc.

public MailSender(

String strFrom, // sender

String[] astrTo, // recipient(s)

String[] astrBCC, // bcc recipient(s), optional

String strSubject, // subject

boolean debugging)

{

ms_strFrom = strFrom; // who the message is from

ms_astrTo = astrTo; // who (plural) the message is to

ms_debugging = debugging; // who (plural) the message is to

// set the host

Properties props = new Properties();

props.put(\"mail.smtp.host\", ms_strSMTPHost);

// create some properties and get the default Session

Session session = Session.getDefaultInstance(props, null);

session.setDebug(ms_debugging);

try {

// create a message

ms_msg = new MimeMessage(session);

// set the from

InternetAddress from = new InternetAddress(strFrom);

ms_msg.setFrom(from);

// set the to

InternetAddress[] address = new InternetAddress[astrTo.length];

for (int i = 0; i astrTo.length; ++i)

{

address[i] = new InternetAddress(astrTo[i]);

}

ms_msg.setRecipients(Message.RecipientType.TO, address);

// set the bcc recipients

if (astrBCC != null)

{

address = new InternetAddress[astrBCC.length];

for (int i = 0; i astrBCC.length; ++i)

{

eh.dbg(\"astrBCC[\" + i + \"] is: \'\" + astrBCC[i] + \"\'\");

address[i] = new InternetAddress(astrBCC[i]);

}

ms_msg.setRecipients(Message.RecipientType.BCC, address);

}

// set the subject

ms_msg.setSubject(strSubject);

// set up the string buffer which will hold the message

ms_strbufMsg = new StringBuffer();

} catch (MessagingException mex) {

mex.printStackTrace(System.err);

} catch (Exception ex) {

ex.printStackTrace(System.err);

}

}

public void ms_add(String strText)

{

ms_strbufMsg.append(strText);

}

public void ms_send()

{

try {

// set the content as plain text

ms_msg.setContent(new String(ms_strbufMsg), \"text/plain\");

// and away

Transport.send(ms_msg);

} catch (Exception ex) {

System.out.println(\"Caught exception in MailSender.ms_send: \" + ex);

}

}
