[英]Sending mail through smtp and gettin error?
这是我的代码。 我收到以下异常。
final String username = "mymail@gmail.com";
final String password = "mypass";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected javax.mail.PasswordAuthentication getPasswordAuthentication() {
return new javax.mail.PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("fazeen.ahmad93@gmail.com"));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("fazeenahmad1993@gmail.com"));
message.setSubject("Testing subject");
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText("test body");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
message.setContent(multipart);
Transport.send(message);
我收到的异常:

我认为您缺少将以下保险丝添加到属性中的功能。
mail.smtp.starttls.required=true
使用此运行代码发送邮件
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;

public class MailSend {

//compose message

message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
message.setSubject("Welcome!!");
message.setText("Hiii buddy ");
Transport.send(message);
System.out.println("message sent successfully");
} catch (MessagingException e) {throw new RuntimeException(e);}
}
}
如果您的计算机上没有smtp服务器,请下载该服务器并在下载后运行。
尝试这个
我当时使用的是旧版本的mail.jar,请使用此jar mail-1.4.7.jar进行身份验证。 要打开帐户访问权限,请执行以下操作: https : //www.google.com/settings/security/lesssecureapps (打开)如果使用谷歌SMTP的问题
