props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host","smtp.gmail.com");
props.put("mail.smtp.port","587");
//get Session
Session session = Session.getDefaultInstance(props);
Transport transport;
while (true) {
Scanner scanner=new Scanner(System.in);
System.out.println("Enter Email Address ");
String userName=scanner.nextLine();
System.out.println("Enter password ");
String passwd=scanner.nextLine();
try {
transport = session.getTransport("smtp");
transport.connect("smtp.gmail.com", userName,
passwd);
transport.close();
System.out.println("SuccessFull");
//Authentication success
} catch (Exception e) {
System.out.println("Session Failed ");
// e.printStackTrace();
}
}
}

只需使用String.split(" ")[0]
即可收到错误代码。
