<p align="center"><big><strong>在jsp中发送email</strong></big></p>
<div align="right">(编译/Blueski)</div>
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。 <br>
(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。) <br>
<br>
以下scriptlet利用SmtpClient类在jsp文件中发送email。 <br>
<br>
<%@ page import="sun.net.smtp.SmtpClient, java.io.*" %><br>
<%<br>
String from="gseshadri@hotmail.com";<br>
String to="govind@jguru.com, govi@bigfoot.com";<br>
try{<br>
SmtpClient client = new SmtpClient("mail.xxxxx.xxx");<br>
client.from(from);<br>
client.to(to);<br>
PrintStream message = client.startMessage();<br>
message.println("To: " + to);<br>
message.println("Subject: Sending email from JSP!");<br>
message.println("This was sent from a JSP page!");<br>
message.println();<br>
message.println("Cool beans! :-)");<br>
message.println();<br>
message.println("Govind Seshadri");<br>
message.println("jGuru.com");<br>
message.println();<br>
client.closeServer();<br>
}<br>
catch (IOException e){ <br>
System.out.println("ERROR SENDING EMAIL:"+e);<br>
}<br>
%><br>
<br>
<br>
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：<br>
<br>
<br>
// ms_ prefix is for MailSender class variables<br>
// str prefix is for String<br>
// astr prefix is for array of Strings<br>
// strbuf prefix is for StringBuffers, etc.<br>
public MailSender(<br>
String strFrom, // sender<br>
String[] astrTo, // recipient(s)<br>
String[] astrBCC, // bcc recipient(s), optional<br>
String strSubject, // subject<br>
boolean debugging)<br>
{<br>
ms_strFrom = strFrom; // who the message is from<br>
ms_astrTo = astrTo; // who (plural) the message is to<br>
ms_debugging = debugging; // who (plural) the message is to<br>
<br>
// set the host<br>
Properties props = new Properties();<br>
props.put("mail.smtp.host", ms_strSMTPHost);<br>
<br>
// create some properties and get the default Session<br>
Session session = Session.getDefaultInstance(props, null);<br>
session.setDebug(ms_debugging);<br>
<br>
try {<br>
// create a message<br>
ms_msg = new MimeMessage(session);<br>
<br>
// set the from<br>
InternetAddress from = new InternetAddress(strFrom);<br>
ms_msg.setFrom(from);<br>
<br>
// set the to<br>
InternetAddress[] address = new InternetAddress[astrTo.length];<br>
for (int i = 0; i astrTo.length; ++i)<br>
{<br>
address[i] = new InternetAddress(astrTo[i]);<br>
}<br>
ms_msg.setRecipients(Message.RecipientType.TO, address);<br>
<br>
// set the bcc recipients<br>
if (astrBCC != null)<br>
{<br>
address = new InternetAddress[astrBCC.length];<br>
for (int i = 0; i astrBCC.length; ++i)<br>
{<br>
eh.dbg("astrBCC[" + i + "] is: '" + astrBCC[i] + "'");<br>
address[i] = new InternetAddress(astrBCC[i]);<br>
}<br>
ms_msg.setRecipients(Message.RecipientType.BCC, address);<br>
}<br>
<br>
// set the subject<br>
ms_msg.setSubject(strSubject);<br>
<br>
// set up the string buffer which will hold the message<br>
ms_strbufMsg = new StringBuffer();<br>
<br>
} catch (MessagingException mex) {<br>
mex.printStackTrace(System.err);<br>
} catch (Exception ex) {<br>
ex.printStackTrace(System.err);<br>
}<br>
}<br>
<br>
public void ms_add(String strText)<br>
{<br>
ms_strbufMsg.append(strText);<br>
}<br>
<br>
public void ms_send()<br>
{<br>
try {<br>
// set the content as plain text<br>
ms_msg.setContent(new String(ms_strbufMsg), "text/plain");<br>
<br>
// and away<br>
Transport.send(ms_msg);<br>
} catch (Exception ex) {<br>
System.out.println("Caught exception in MailSender.ms_send: " + ex);<br>
}<br>
}
