我发现一个教程可以帮助我创建一个邮件发件人,在第一次尝试时工作正常,但是在我关闭 netbeans 并再次尝试之后,oups,有一个错误,我无法弄清楚,netbeans 通知:connot find symbol , symbol attachFileString,
这是我的电子邮件代码
import java.io.IOException;
import java.util.Date;
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class Emailer {
public static void sendEmailWithAttachments(String host, String port,
final String userName, final String password, String toAddress,
String subject, String message, String[] attachFiles)
throws AddressException, MessagingException {
// sets SMTP server properties
Properties properties = new Properties();
properties.put("mail.smtp.host", host);
properties.put("mail.smtp.port", port);
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.user", userName);
properties.put("mail.password", password);
// creates a new session with an authenticator
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
};
Session session = Session.getInstance(properties, auth);
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
InternetAddress[] toAddresses = { new InternetAddress(toAddress) };
msg.setRecipients(Message.RecipientType.TO, toAddresses);
msg.setSubject(subject);
msg.setSentDate(new Date());
// creates message part
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(message, "text/html");
// creates multi-part
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// adds attachments
if (attachFiles != null && attachFiles.length > 0) {
for (String filePath : attachFiles) {
MimeBodyPart attachPart = new MimeBodyPart();
try {
attachPart.attachFile(filePath);
} catch (IOException ex) {
ex.printStackTrace();
}
multipart.addodyPart(attachPart);
}
}
// sets the multi-part as e-mail's content
msg.setContent(multipart);
// sends the e-mail
Transport.send(msg);
}
}
错误是
java.lang.RuntimeException: Uncompilable source code - exception java.io.IOException is never thrown in body of corresponding try statement
at Emailer.sendEmailWithAttachments(Emailer.java:63)
第 63 行(Emailer.java:63)是:
attachPart.attachFile(filePath);
非常感谢
