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); } } 返回类别: 教程 上一教程: JSP调用JAVABEAN在网页上动态生成柱状图 下一教程: JSP源码实例1(输出) 您可以阅读与"在JSP中发送EMAIL"相关的教程: · 邮件发送简朴例子-JSP文件 · JSP中EMAIL格式的判定 · 通过JSP发送动态图像 · JSP发送邮件实例 · JSP与JAVAMAIL之4(发送HTML格式邮件) |
