Java Mail 发送邮件(带附件) 已成功,但是附件预览错误且无法下载
一开始我以为是文件编码的问题,尝试过改变文件的编码,但是依旧如此;但是,当我反过来从 QQ 邮箱发送邮件到 yeah 邮箱时,发现是没有问题的
下面是我的代码
@Test
public void test3() throws AddressException, Exception{
//1)创建Session - 连接邮件服务器
Properties props = new Properties();
//邮件服务器地址 // smtp
props.setProperty("mail.smtp.host", "smtp.yeah.net");
//是否开启加密验证登录
props.setProperty("mail.smtp.auth", "true");
Session session = Session.getInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("synchronization@yeah.net","hdljd1lzsx");
}
});
//开启debug，可以看到发送邮件的过程
session.setDebug(true);
//2)创建一封邮件 -- 设置邮件内容
MimeMessage mail = new MimeMessage(session);
//发件人
mail.setFrom(new InternetAddress("synchronization@yeah.net"));
//收件人
mail.setRecipient(RecipientType.TO, new InternetAddress("1286640174@qq.com"));
//标题
mail.setSubject("周末远程会议研讨");
//装载邮件数据
MimeMultipart mmp = new MimeMultipart();
MimeBodyPart content = new MimeBodyPart();
MimeBodyPart attachment1 = new MimeBodyPart();
String filename = "缓存.txt";
attachment1.attachFile(new File("src\缓存.txt"));
attachment1.setFileName(MimeUtility.encodeWord(filename));
content.setText("带附件邮件的正文");
mmp.addBodyPart(content, 0);
mmp.addBodyPart(attachment1, 1);
mail.setContent(mmp);
//3)发送邮件
Transport.send(mail);
}
当然我也尝试过发送其他文件,如图片
@Test
public void test3() throws AddressException, Exception{
//1)创建Session - 连接邮件服务器
Properties props = new Properties();
//邮件服务器地址 // smtp
props.setProperty("mail.smtp.host", "smtp.qq.com");
//是否开启加密验证登录
props.setProperty("mail.smtp.auth", "true");
Session session = Session.getInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("1286640174@qq.com","kdfaltvozuzybaae");
}
});
//开启debug，可以看到发送邮件的过程
session.setDebug(true);
//2)创建一封邮件 -- 设置邮件内容
MimeMessage mail = new MimeMessage(session);
//发件人
mail.setFrom(new InternetAddress("1286640174@qq.com"));
//收件人
mail.setRecipient(RecipientType.TO, new InternetAddress("synchronization@yeah.net"));
//标题
mail.setSubject("周末远程会议研讨");
//装载邮件数据
MimeMultipart mmp = new MimeMultipart();
MimeBodyPart content = new MimeBodyPart();
MimeBodyPart attachment1 = new MimeBodyPart();
String filename = "1.jpg";
attachment1.attachFile(new File("src\1.jpg"));
attachment1.setFileName(MimeUtility.encodeWord(filename));
content.setText("带附件邮件的正文");
mmp.addBodyPart(content, 0);
mmp.addBodyPart(attachment1, 1);
mail.setContent(mmp);
//3)发送邮件
Transport.send(mail);
}
//下面的是项目目录结构
----- src
---- 缓存.txt
---- com.kongzi.test
---- MailTest.java
但是出现长时间的等待,控制台一堆乱码
