javaMail邮件发送系统,大家可以写个通用的底层方法去实现
代码如下
//邮件系统添加附件
public static MimeBodyPart createAttachment(String fileName) throws Exception {
MimeBodyPart attachmentPart = new MimeBodyPart();
FileDataSource fds = new FileDataSource(fileName);
attachmentPart.setDataHandler(new DataHandler(fds));
attachmentPart.setFileName(fds.getName());
return attachmentPart;
}
//邮件的正文部分
public static MimeBodyPart createContent(String body)throws Exception {
MimeBodyPart contentBody = new MimeBodyPart();
// 用于组合文本和图片,"related"型的MimeMultipart对象
MimeMultipart contentMulti = new MimeMultipart();
// 正文的文本部分
MimeBodyPart textBody = new MimeBodyPart();
textBody.setContent(body, "text/html;charset=gbk");
contentMulti.addBodyPart(textBody);
// 将上面"related"型的 MimeMultipart 对象作为邮件的正文
contentBody.setContent(contentMulti);
return contentBody;
}
/**
* @param mailInfo 待发送的邮件信息
* @throws Exception
*/
public static boolean sendHtmlMail(MailSenderInfo mailInfo) throws Exception{
// 判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
//如果需要身份认证,则创建一个密码验证器
if (mailInfo.isValidate()) {
authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
}
// 根据邮件会话属性和密码验证器构造一个发送邮件的session
Session sendMailSession = Session.getDefaultInstance(pro,authenticator);
try {
// 根据session创建一个邮件消息
Message mailMessage = new MimeMessage(sendMailSession);
// 创建邮件发送者地址
Address from = new InternetAddress(mailInfo.getFromAddress());
// 设置邮件消息的发送者
mailMessage.setFrom(from);
// 创建邮件的接收者地址,并设置到邮件消息中
Address to = new InternetAddress(mailInfo.getToAddress());
// Message.RecipientType.TO属性表示接收者的类型为TO
mailMessage.setRecipient(Message.RecipientType.TO,to);
// 设置邮件消息的主题
mailMessage.setSubject(mailInfo.getSubject());
// 设置邮件消息发送的时间
mailMessage.setSentDate(new Date());
MimeMultipart mainPart = new MimeMultipart();
MimeBodyPart content = createContent(mailInfo.getContent().toString());
MimeBodyPart attachment = createAttachment("E:\\11.mp3");
mainPart.addBodyPart(content);
mainPart.addBodyPart(attachment);
mailMessage.setContent(mainPart);
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}

关于多附件也是一样,在上传附件时,将其循环上传就OK了,大家可以自己去尝试!
