我正在尝试使用 java 发送电子邮件，但我的代码抛出异常 这里出现异常javax.mail.MessagingException:无法将命令发送到 SMTP 主机；
我正在使用以下代码
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class SendEmail {
public static void main(String args[]) {
final String username ="mymail@gmail.com";
final String password = "password here";
final String xtomail="email here";
final String cc="email here";
final String bcc="email here";
final String xsub="heavy discount for static websites";
final String xbody="we are great leader in software industry";
Properties props = new Properties();
try{
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");
} catch(Exception ex) {
System.out.println("exception here"+ex);
}
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(username));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(xtomail));
message.addRecipients(Message.RecipientType.CC,InternetAddress.parse(cc));
message.addRecipients(Message.RecipientType.BCC,InternetAddress.parse(bcc));
message.setSubject(xsub);
message.setText(xbody);
Transport.send(message);
System.out.println("email send");
}
catch (Exception e) {
System.out.println("Exception here"+e);
}
}
}
最佳答案
debug output 是什么意思？显示？
您的 Gmail 帐户是否已启用 less secure apps ？
