Java发送电子邮件：smtp.gmail.com错误

Question

I have the following java code to send email:

Properties props = new Properties();

props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");

Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() 
{
return new PasswordAuthentication("erjobertolazo@gmail.com", "mypassword");
}
});

try {

Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("erjobertolazo@gmail.com"));

Address[] toUser = InternetAddress 
.parse("Recipient1@gmail.com, Recipient2@hotmail.com, Recipient3@yahoo.com.br");  
message.setRecipients(Message.RecipientType.TO, toUser);
message.setSubject("TEST SEND EMAIL");//Assunto
message.setText("THIS IS JUST A TEST!");

Transport.send(message);

I get the following error message:

Answer 1

1. Ensure that you don't have enabled " Two factor authentication "
2. Navigate to: " https://myaccount.google.com/lesssecureapps?pli=1 " and turn on " Access for less secure apps "
