我想使用JSF实现带附件的邮件。我试过这段代码：
private Part file;
private String sendFromGMail(String from, String pass, String[] to, String subject, String body)
{
String status;
Properties props = System.getProperties();
String host = "smtp.gmail.com";
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props);
MimeMessage message = new MimeMessage(session);
try
{
message.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
// To get the array of addresses
for (int i = 0; i < to.length; i++)
{
toAddress[i] = new InternetAddress(to[i]);
}
for (int i = 0; i < toAddress.length; i++)
{
message.addRecipient(Message.RecipientType.TO, toAddress[i]);
}
message.setSubject(subject);
message.setText(body);
MimeBodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
messageBodyPart = new MimeBodyPart();
messageBodyPart.setDataHandler(new DataHandler(file, file.getName()));
messageBodyPart.setFileName(file.getName());
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
catch (AddressException ae)
{
ae.printStackTrace();
return status = "Cannot send Message!";
}
catch (MessagingException me)
{
me.printStackTrace();
return status = "Cannot send Message!";
}
return status = "Message is send!";
}
//.......................
public Part getFile() {
return file;
}
public void setFile(Part file) {
this.file = file;
}
public void upload() {
if (file != null) {
try (InputStream inputStream = file.getInputStream(); FileOutputStream outputStream = new FileOutputStream("D:" + File.separator + "files" + File.separator + file.getSubmittedFileName())) {
int bytesRead = 0;
final byte[] chunck = new byte[1024];
while ((bytesRead = inputStream.read(chunck)) != -1) {
outputStream.write(chunck, 0, bytesRead);
}
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Upload successfully ended!"));
} catch (IOException e) {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Upload failed!"));
}
}
}
但是在Tomcat日志文件中我收到此错误：

这个问题有解决方法吗？
在我的情况下，我想使用h:inputFile上传文件并将其作为电子邮件附件发送。但我得到错误。
