添加附件模块
/* * 当发送包含附件的邮件时,邮件体就为多部件形式! * 1. 创建一个多部件的部件内容!MimeMultipart * MimeMultipart就是一个集合,用来装载多个主体部件! * 2. 我们需要创建两个主体部件,一个是文本内容的,另一个是附件的。 * 主体部件叫MimeBodyPart * 3. 把MimeMultipart设置给MimeMessage的内容! */ MimeMultipart list = new MimeMultipart();//创建多部分内容 // 创建MimeBodyPart MimeBodyPart part1 = new MimeBodyPart(); // 设置主体部件的内容 part1.setContent("这是一封包含附件的垃圾邮件", "text/html;charset=utf-8"); // 把主体部件添加到集合中 list.addBodyPart(part1); // 创建MimeBodyPart MimeBodyPart part2 = new MimeBodyPart(); part2.attachFile(new File("F:xxx.jpg"));//设置附件的内容 part2.setFileName(MimeUtility.encodeText("xxx.jpg"));//设置显示的文件名称,其中encodeText用来处理中文乱码问题 list.addBodyPart(part2); message.setContent(list);//把它设置给邮件作为邮件的内容。
利用jar包来进行
(F:\常用综合\常用jar包\JavaMail\itcast-tools-1.4.2.jar)
@Test public void fun2() throws Exception{ Session session = MailUtils.createSession("smtp.qq.com","1623851096","yu1623851096"); Mail mail = new Mail("1623851096@qq.com","987039024@qq.com","这是经过包装的测试文件","余文辉是大帅哥"); AttachBean attachBean = new AttachBean(new File("D:/Pictures/doubi.jpg"),"逗比.jpg"); mail.addAttach(attachBean); MailUtils.send(session,mail); }
