我知道有关于此的问题已经存在 但我完全尝试了它们，但仍然有同样的错误
我在tomcat 7中运行ubuntu（VPS）的java web应用程序
我安装了postfix作为SMTP（如果我错了，请纠正我）
public class SendMail {
public void send(String user){
final Logger logger = Logger.getLogger(SendMail.class);
// Recipient's email ID needs to be mentioned.
String to = "myemail@gmail.com";
String from = "root@mydomain";
String host = "mydomain";
// Get system properties
Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", host);
properties.setProperty("mail.smtp.starttls.enable", "true");
properties.setProperty("mail.smtp.port", "587");
// Get the default Session object.
Session session = Session.getInstance(properties);
try {
// Create a default MimeMessage object.
MimeMessage message = new MimeMessage(session);
// Set From: header field of the header.
message.setFrom(new InternetAddress(from));
// Set To: header field of the header.
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set Subject: header field
message.setSubject("This is the Subject Line!");
// Now set the actual message
message.setText(text);
// Send message
Transport.send(message);
System.out.println("Sent message successfully....");
} catch (MessagingException mex) {
logger.error("This is error : "+mex);
mex.printStackTrace();
}
}
}

我在一些例子中看到他们放了用户名＆amp;密码，但我不确定这是什么确切的凭证？
答案 0 :(得分：0)
Session session = Session.getInstance(properties,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(<username>, <password>);
}
});
答案 1 :(得分：0)
根据堆栈跟踪，您应该在以下位置获取seminair的源代码：
ns1.webapp.com
也许getDefaultUserInJSON默认使用错误的用户名或密码
一般情况下也不做：
logger.error（“这是错误：”+ mex）; mex.printStackTrace（）;
代替：
logger.error（“这是错误：”，mex）;
