用java写收发邮件的程序，求助，在线

主要类用到了 Session Messager Address Transport等， 代码如下： public class MailUtils{ private static Properties p = System.getProperties(); /**获取Message对象*/ private static Message getMessage() throws Exception{ p.put("mail.smtp.host", ""); //新浪邮箱服务器 p.put("mail.smtp.username","发送人新浪邮箱地址"); p.put("mail.smtp.auth","true"); //发送人邮箱密码 p.put("mail.smtp.pswd","xxxxxxxx"); //获取Session对象 Session session = Session.getInstance(p, new Authenticator(){ protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(p.getProperty("mail.smtp.username"), p.getProperty("mail.smtp.pswd")); } }); session.setDebug(true); //创建Message对象 Message message = new MimeMessage(session); message.setFrom(new Address(p.getProperty("mail.smtp.username"), "...getProperty("获取Session对象 Session session = Session.smtp;.parse("mail;);/.put(" message.setReplyTo(Address;); public static void sendHTML(String content) { Message message = getMessage(); /text//.username".setFrom(new Address(p.getInstance(p.smtp;/ } /.smtp; p： public class MailUtils{ private static Properties p = System,"mail.pswd")).host"mail.getProperties(); session;smtp.put("设置收件人点击回复的时候回复地址 message.username" return message ;创建Message对象 Message message = new MimeMessage(session).smtp;发送人新浪邮箱地址";);设置邮件标题"**获取Message对象*/.setDebug(true); public static void sendText(String text) { Message message = getMessage()，可随意设置;收件人地址".put(" message;); /mail, new Address(" /, new Authenticator(){ protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(p,".smtp; /).setContent(content.setRecipient(Message; //**发送文本格式的邮件*/)).smtp; message;mail; message;可以是发件人地址; Transport; private static Message getMessage() throws Exception{ p; } /true"/.send(message).sina;**发送html格式的邮件*/mail;);新浪邮箱服务器 p, ").smtp; /.put(".getProperty(".RecipientType; /发送人邮箱密码 p;))， 代码如下，也可不设置"/.username".TO;charset=utf-8"mail;;),"html; } })"设置发送人模式 TO代表主发送 message; Transport,"xxxxxxxx"，也可以是其他".pswd", ".setText(text);发送者别名.getProperty(", p.send(message)主要类用到了 Session Messager Address Transport等;)).setSubject(".auth"

如何用java实现发送html格式的邮件

首先Java发送邮件需要用到JavaMail，先到Oracle官网上下载好最新版本的JavaMail（刚才看了一下，最新是1.5.3），把下载的这个jar文件放到classpath里（如果是Web项目，就放到WEB-INF/lib目录下。

JavaMail主要支持发送纯文本的和html格式的邮件。

发送html格式的邮件的一个例程如下： ? ?import?Address; ?import?.MimeMessage; ?import?.MimeUtility; ?import?javax.mail.Session; ?import?javax.mail.MessagingException; import?javax.mail.Transport; public?class?SendHtmlMail?{ ?????public?static?void?sendMessage(String?smtpHost, ????????????????????????????????????String?from,?String?to, ????????????????????????????????????String?subject,?String?messageText) ?????????????throws?MessagingException,java.io.UnsupportedEncodingException?{ ?????????//?Step?1:??Configure?the?mail?session ?????????System.out.println("Configuring?mail?session?for:?"?+?smtpHost); ?????????java.util.Properties?props?=?new?java.util.Properties(); ?????????props.setProperty("mail.smtp.auth",?"true");//指定是否需要SMTP验证 ?????????props.setProperty("mail.smtp.host",?smtpHost);//指定SMTP服务器 ?????????props.put("mail.transport.protocol",?"smtp"); ?????????Session?mailSession?=?Session.getDefaultInstance(props); ?????????mailSession.setDebug(true);//是否在控制台显示debug信息 ?????????//?Step?2:??Construct?the?message ?????????System.out.println("Constructing?message?-??from="?+?from?+?"??to="?+?to); ?????????Address?fromAddress?=?new?Address(from); ?????????Address?toAddress?=?new?Address(to); ?????????MimeMessage?testMessage?=?new?MimeMessage(mailSession); ?????????testMessage.setFrom(fromAddress); ?????????testMessage.addRecipient(javax.mail.Message.RecipientType.TO,?toAddress); ?????????testMessage.setSentDate(new?java.util.Date()); ?????????testMessage.setSubject(MimeUtility.encodeText(subject,"gb2312","B")); ????????testMessage.setContent(messageText,?"text/html;charset=gb2312"); ?????????System.out.println("Message?constructed"); ????????//?Step?3:??Now?send?the?message ?????????Transport?transport?=?mailSession.getTransport("smtp"); ?????????transport.connect(smtpHost,?"webmaster",?"password"); ?????????transport.sendMessage(testMessage,?testMessage.getAllRecipients()); ?????????transport.close(); ?????????System.out.println("Message?sent!"); ?????} ?????public?static?void?main(String[]?args)?{ ?????????String?smtpHost?=?"localhost"; ?????????String?from?=?"webmaster@"; ?????????String?to?=?"mfc42d@"; ?????????String?subject?=?"html邮件测试";?//subject?javamail自动转码 ?????????StringBuffer?theMessage?=?new?StringBuffer(); ?????????theMessage.append("<h2><font?color=red>这倒霉孩子</font></h2>"); ?????????theMessage.append("<hr>"); ?????????theMessage.append("<i>年年失望年年望</i>"); ?????????try?{ ????????????SendHtmlMail.sendMessage(smtpHost,?from,?to,?subject,?theMessage.toString()); ?????????} ?????????catch?(javax.mail.MessagingException?exc)?{ ?????????????exc.printStackTrace(); ?????????} ?????????catch?(java.io.UnsupportedEncodingException?exc)?{ ?????????????exc.printStackTrace(); ?????????} ?????} ?} JavaMail是封装了很多邮件操作的，所以使用起来不很困难，建议你到JavaMail官网看一下API或下载Java Doc API文档。
