【问题描述】：
这是我用 Java 发送带有附件的 MultiPartEmail 的代码：
public static void main(String[] args) {
// Create The Attachment
EmailAttachment attachment = new EmailAttachment();
attachment.setPath("check.png");
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription("My file on my system");
attachment.setName("Check icon");
// Create The Email
MultiPartEmail email = new MultiPartEmail();
try {
email.setHostName("smtp.googlemail.com");
email.setAuthentication("MyUsername", "Mypassword");
email.setFrom("Myemail@gmail.com");
email.addTo("myfriend@gmail.com");
email.setMsg("Body Of Message");
email.attach(attachment);
email.send();
} catch (EmailException ee) {
ee.printStackTrace();
}
}
但是，发生了这个异常：
