收集整理的这篇文章主要介绍了在jsp中发送email，觉得挺不错的，现在分享给大家，也给大家做个参考。 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);
}
}
