实现邮件收发功能需要3个jar包&＃xff1a;
1.JavaMail组件保内的mail.jar和smtp.jar包
2.JAF组件包里的activition.jar。
复制到WebRoot/WEB-INF/lib目录下。
一、编写index.jsp页面&＃xff0c;具体代码如下&＃xff1a;
1 <%&＃64; page language&＃61;"java" contentType&＃61;"text/html; charset&＃61;gb2312"
2 pageEncoding&＃61;"gb2312"%>
3 DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

5 <head>
6 <meta http-equiv&＃61;"Content-Type" content&＃61;"text/html; charset&＃61;gb2312">

8 head>
9 <body>
10 <form action&＃61;"sendMail.jsp" method&＃61;"post" name&＃61;"form1">

12 bgcolor&＃61;"#006600" class&＃61;"black">

30 <tr>
31 <td height&＃61;"53" colspan&＃61;"2" bgcolor&＃61;"#ffffff">

61 tr>
62 table>
63 form>
64 body>
65 html>
二、创建sendMail.jsp页面&＃xff0c;具体代码如下&＃xff1a;
<%&＃64; page language&＃61;"java" contentType&＃61;"text/html; charset&＃61;gb2312"pageEncoding&＃61;"gb2312"%>
<%request.setCharacterEncoding("gb2312"); %>
<%&＃64; page import&＃61;"java.util.*,javax.mail.*" %>
<%&＃64; page import&＃61;"javax.mail.internet.*"%>
<%&＃64; page import&＃61;"javax.activation.*" %>
<%&＃64; page import&＃61;"java.net.*" %>
<%try{ String tto&＃61;request.getParameter("to");String ttitle&＃61;request.getParameter("title");String emailtype&＃61;request.getParameter("emailtype");String tcontent&＃61;request.getParameter("content");String tfj1&＃61;request.getParameter("fj1");String tfj2&＃61;request.getParameter("fj2");String tfj3&＃61;request.getParameter("fj3");//声明properities存储发件服务器信息Properties props&＃61;new Properties();props.put("mail.smtp.host", "smtp.qq.com");props.put("mail.smtp.auth", "true");//创建邮件回话Session s&＃61;Session.getInstance(props);s.setDebug(true);//创建一个消息对象MimeMessage message&＃61;new MimeMessage(s);InternetAddress from&＃61;new InternetAddress("393743083&＃64;qq.com");message.setFrom(from);InternetAddress to&＃61;new InternetAddress(tto);message.setRecipient(Message.RecipientType.TO, to);message.setSubject(ttitle);message.setSentDate(new Date());Multipart mm &＃61; new MimeMultipart();BodyPart mdp&＃61;new MimeBodyPart();mdp.setContent(tcontent, emailtype&＃43;";charset&＃61;gb2312");mm.addBodyPart(mdp);//附件1mdp&＃61;new MimeBodyPart();DataHandler dh&＃61;new DataHandler(tfj1,"text/plain;charset&＃61;gb2312");mdp.setFileName("text.txt");mdp.setDataHandler(dh);mm.addBodyPart(mdp);//附件2mdp&＃61;new MimeBodyPart();FileDataSource fds&＃61;new FileDataSource(tfj2);dh&＃61;new DataHandler(fds);int ddd&＃61;tfj2.lastIndexOf("\\");String fname&＃61;tfj2.substring(ddd);String ffname&＃61;new String(fname.getBytes("gb2312"),"ISO8859-1");mdp.setFileName(ffname);mdp.setDataHandler(dh);mm.addBodyPart(mdp);//附件3mdp&＃61;new MimeBodyPart();URL urlfj&＃61;new URL(tfj3);URLDataSource ur&＃61;new URLDataSource(urlfj);dh&＃61;new DataHandler(ur);int ttt&＃61;tfj3.lastIndexOf("/");String urlname&＃61;tfj3.substring(ttt);mdp.setFileName(urlname);mdp.setDataHandler(dh);mm.addBodyPart(mdp);message.setContent(mm);message.saveChanges();//发送邮件Transport transport&＃61;s.getTransport("smtp");transport.connect("smtp.qq.com",用户名,密码);transport.sendMessage(message, message.getAllRecipients());transport.close();%><%}catch(MessagingException e){ out.println(e.toString());}%>
注&＃xff1a;腾讯邮箱需要开通smtp功能。
