窗体顶端 ranran2010 java mail 使用介绍 转自：/snoopy/articles/129932.html 最近在项目中用到发送邮件的功能，由于以前没有接触过，找了很多资料才终于把它弄出来，今天写下这些，算是做个总结吧。 1、首先定义一个邮件的数据结构类 public class EmailData() { ???? String from ??= null;??//发件人 ?????String[] recipients = null;??//收件人,可以多个 ?????String subject ??= null;??//邮件主题 ?????String content ??= null;??//邮件内容 ?????String contentType ?= null;??//邮件内容格式(文本或html) ?????String fileName ?= null;??//附件文件名(目前只提供一个附件) ? ?????//下面是相应的setter/getter方法，省略.. } 2、发送不带附件的邮件(包括文本格式和html两种格式) public void postMail(EmailData emailData) ?throws MessagingException,Exception { ?? ?String from ??= emailData.getFrom(); ?String[] recipients = emailData.getRecipents(); ?String subject ??= emailData.getSubject(); ?String content ??= emailData.getContent(); ?String contentType?= emailData.getContentType(); ?String fileName??= emailData.getFileName(); ? ??? if (recipients != null recipients.length 0) { ???? Properties props = new Properties(); ???? //设置邮件服务器地址，连接超时时限等信息 ???? props.put(mail.smtp.host, 33);?//33邮件服务器 ???? props.put(mail.smtp.connectiontimeout, 10000);?// ??props.put(mail.smtp.timeout, 10000);???// ???? ???? //创建缺省的session对象 ???? Session session = Session.getDefaultInstance(props, null); ? ???? //创建message对象 ???? Message msg = new MimeMessage(session); ? ???? //设置发件人和收件人 ???? InternetAddress addressFrom = new InternetAddress(from); ???? msg.setFrom(addressFrom);?? ???? InternetAddress[] addressTo = new InternetAddress[recipients.length]; ???? for (int i = 0; i recipients.length; i++){ ???????? addressTo[i] = new InternetAddress(recipients[i]); ???? } ???? msg.setRecipients(Message.RecipientType.TO, addressTo); ?? ??//设置邮件标题，中文编码 ???? subject = MimeUtility.encodeText(new String(subject.getBytes(), GB2312), GB2312, B); ???? msg.setSubject(subject); ???? ???? //设置邮件内容,区分文本格式和HTML格式 ???? if (contentType == null || contentType.equals(text)) { ???? ?msg.setText(content); ??} else if (contentType.equals(html)) { ???//给消息对象设置内
