如何解决javax.mail.AuthenticationFailedException问题？
提问于 2010-01-12 17:41:29
我正在和JavaMail做一个sendMail Servlet。我的输出上有javax.mail.AuthenticationFailedException。有谁能帮帮我吗？谢谢。
sendMailServlet代码：
try {
String host = "smtp.gmail.com";
String from = "my@gmail.com";
String pass = "pass";
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
Address fromAddress = new InternetAddress(from);
Address toAddress = new InternetAddress("test1@gmail.com");
message.setFrom(fromAddress);
message.setRecipient(Message.RecipientType.TO, toAddress);
message.setSubject("Testing JavaMail");
message.setText("Welcome to JavaMail");
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
message.saveChanges();
Transport.send(message);
transport.close();
}catch(Exception ex){
out.println("<html><head></head><body>");
out.println("ERROR: " + ex);
out.println("</body></html>");
}GlassFish 2.1上的输出：

您需要实现自定义Authenticator
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
class GMailAuthenticator extends Authenticator {
String user;
String pw;
public GMailAuthenticator (String username, String password)
{
super();
this.user = username;
this.pw = password;
}
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(user, pw);
}
}现在在Session中使用它
Session session = Session.getInstance(props, new GMailAuthenticator(username, password));也可以查看JavaMail FAQ

此错误来自google安全...这可以通过启用不太安全的解决方案来解决。
转到此链接："https://www.google.com/settings/security/lesssecureapps“，并设置”打开“，然后您的应用程序肯定会运行。

我在下面的代码行中遗漏了这个验证器对象参数
Session session = Session.getInstance(props, new GMailAuthenticator(username, password));这行代码解决了我的问题，现在我可以通过Java应用程序发送邮件了。代码的其余部分很简单，就像上面一样。
