Solve error javax.mail.AuthenticationFailedException
提问by Fatin Az
I'm not familiar with this function to send mail in java. I'm getting an error while sending email to reset a password. Hope you can give me a solution.
我不熟悉这个在java中发送邮件的功能。我在发送电子邮件以重置密码时遇到错误。希望你能给我一个解决方案。
Below is my code:
下面是我的代码：
public synchronized static boolean sendMailAdvance(String emailTo, String subject, String body)
{
String host = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-ADDRESS");
String userName = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-USERNAME");
String password = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-PASSWORD");
String port = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-PORT");
String starttls = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-STARTTLS");
String socketFactoryClass = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-SOCKET-CLASS");
String fallback = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-ALLOW-FALLBACK");
try
{
java.util.Properties props = null;
props = System.getProperties();
props.put("mail.smtp.user", userName);
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.debug", "true");
if(!"".equals(port))
{
props.put("mail.smtp.port", port);
props.put("mail.smtp.socketFactory.port", port);
}
if(!"".equals(starttls))
props.put("mail.smtp.starttls.enable",starttls);
if(!"".equals(socketFactoryClass))
props.put("mail.smtp.socketFactory.class",socketFactoryClass);
if(!"".equals(fallback))
props.put("mail.smtp.socketFactory.fallback", fallback);
Session session = Session.getDefaultInstance(props, null);
session.setDebug(true);
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
msg.setSubject(subject);
msg.setText(body, "ISO-8859-1");
msg.setSentDate(new Date());
msg.setHeader("content-Type", "text/html;charset=\"ISO-8859-1\"");
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(emailTo));
msg.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect(host, userName, password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
return true;
}
catch (Exception mex)
{
mex.printStackTrace();
return false;
}
}
Throws the following error:
抛出以下错误：

You should change the port to 587, I tested your code and it's working fine
您应该将端口更改为587，我测试了您的代码并且它工作正常
If error still happens, please change session variable to code below:
如果仍然发生错误，请将会话变量更改为以下代码：
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
});

trying to connect to host "smtp.gmail.com", port 465, isSSL false
You got your gmail smtp setting wrong. Gmail requires SSL. Please see tutorials on how to send email via Java via Gmail SMTP, eg: http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/
您的 gmail smtp 设置错误。Gmail 需要 SSL。请参阅有关如何通过 Gmail SMTP 通过 Java 发送电子邮件的教程，例如：http: //www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/

2 possible reasons:
2个可能的原因：
- Your username may require the entire email id '[email protected]'
- Most obvious: The password is wrong. Debug to see if the password being used is correct.
- 您的用户名可能需要完整的电子邮件 ID '[email protected]'
- 最明显的是：密码错误。调试以查看所使用的密码是否正确。

Most of AuthenticationFieldException Error occur when sign-in attempted prevented, login your gmail first and go to https://www.google.com/settings/security/lesssecureappsand check turn on. I solved this kind of problem like this way.
大多数 AuthenticationFieldException 错误在登录尝试被阻止时发生，首先登录您的 gmail 并转到https://www.google.com/settings/security/lesssecureapps并检查打开。我是这样解决这类问题的。

Just in case anyone comes looking a solution for this problem.
以防万一有人来寻找这个问题的解决方案。
The Authentication problems can be alleviated by activating the google 2-step verification for the account in use and creating an app specific password. I had the same problem as the OP. Enabling 2-step worked.
可以通过为正在使用的帐户激活谷歌两步验证并创建应用程序特定密码来缓解身份验证问题。我遇到了与 OP 相同的问题。启用两步工作。

When i changed session debug to true
当我将会话调试更改为 true 时
Session session = Session.getDefaultInstance(props, new GMailAuthenticator("[email protected]", "xxxxx"));

From the steps in the link, I followed each steps. When I changed my password with mix of letters, numbers, and symbols to be my surprise the email was generated without authentication exception.
根据链接中的步骤，我遵循了每个步骤。当我用字母、数字和符号的混合更改密码时，令我惊讶的是，生成的电子邮件没有身份验证异常。
Note: My old password was more less secure.
