我尝试过：



private void enqSubActionPerformed（java.awt.event.ActionEvent evt）{



final String username =[e-mail];

final String password =Hemas @ 9000;



属性props = new属性（） ;

props.put（mail.smtp.auth，true）;

props.put（mail.smtp.starttls.enable，true ）;

props.put（mail.smtp.host，smtp.gmail.com）; //这是smtp服务器地址

道具。 put（mail.smtp.port，587）; //这是smtp服务器的端口



会话session = Session.getInst ance（props，

new javax.mail.Authenticator（）{

protected PasswordAuthentication getPasswordAuthentication（）{

返回新的PasswordAuthentication（用户名，密码）;

}

}）;



尝试{

留言= new MimeMessage（session）;

message.setFrom（new InternetAddress（[e-mail]））; //来自emailaddress

message.setRecipients（消息。 RecipientType.TO，InternetAddress.parse（[e-mail]））; //发送电子邮件地址

message.setSubject（我的第一封电子邮件）; //设置电子邮件主题

message.setContent（< h：body style =background-color：white; font-family：verdana：color：＃0066CC：xmlns：h =＃unknown>

+如果你这样写了你写的第一封电子邮件！



+&l吨; /体> 中， text / html的; charset = utf-8）; //设置电子邮件的内容正文

Transport.send（message）; //发送整个邮件对象

System.out .println（被发送的电子邮件：完成）; //验证代码被解雇

}

catch（MessagingException e）{

抛出新的RuntimeException（e）; //如果电子邮件地址不好或者不感兴趣

}



}

What I have tried:

private void enqSubActionPerformed(java.awt.event.ActionEvent evt) {

final String username = "[e-mail]";
final String password = "Hemas@9000";

Properties props = new Properties();
props.put("mail.smtp.auth","true");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.host","smtp.gmail.com");// this is the smtp server address
props.put("mail.smtp.port","587");//This is the port for the smtp server

Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(username, password);
}
});

try{
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("[e-mail]"));//from emailaddress
message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("[e-mail]"));//to email address
message.setSubject("My first Email");//sets subject of email
message.setContent("<h:body style="background-color:white;font-family:verdana:color:#0066CC:" xmlns:h="#unknown">"
+"if you are getting this you wrote your first email!

"
+"</body>","text/html; charset=utf-8");//Sets the content body of the email
Transport.send(message);//sends the entire message object
System.out.println("was the email sent: Done");// verifies that the code fired
}
catch(MessagingException e){
throw new RuntimeException(e);// If the email address is bad or doesnt excist
}

}

推荐答案

需要注意的一点是，在大多数Google SMTP服务器的情况下，如果您的帐户不允许，它将不允许直接使用SMTP。在这种情况下，我看到许多开发人员编写了协议API的正确实现，但他们仍然无法发送电子邮件。在这种情况下，请确保您的帐户允许通过身份验证进行SMTP通信。它在您的设置中，检查它。



后来，问题仍然是authenti阳离子到您的帐户。例如，请参阅错误消息：

One thing to note is that, in most of the cases of Google SMTP server, is that it won't allow SMTP consumption directly, if your account doesn't allow. In many cases, I have seen that many developers have written a correct implementation of the protocol API, but still they cannot send the email. In that case, make sure that your account allows SMTP communication through your authentication. It is in your settings, check it.

Later, the problem is still the authentication to your account. For example, see the error message:

Quote：

javax.mail。 AuthenticationFailedException ...请通过Web浏览器登录，然后重试。

javax.mail.AuthenticationFailedException...Please log in via your web browser and then try again.

这表示您需要对系统进行身份验证才能使用该帐户。 Google不允许您的应用使用此功能。



以下其中一项原因可能是：



1.您的帐户是新帐户。谷歌打击垃圾邮件;或者这就是他们告诉我们的。 ：笑：

2.确保您可以从网络浏览器登录帐户，试试运气： mail.google。 com 。

3.确保按照安全标准支持应用程序; SSL，端口和身份验证等。

4.更多。



这些是您需要保留的一些主要内容心神。您的代码是正确的，问题在于身份验证。用户名/密码不正确，否则Google会阻止您的应用进行通信。

This tells that you need to authenticate the system to use that account. Google does not allow your application to use this.

One of the following may be the reason:

1. Your account is a new one. Google fights against spam; or that is what they tell us. :laugh:
2. Make sure you can sign in to account from web browser, try your luck at: mail.google.com.
3. Make sure application is supported as per security standards; SSL, port and authentication etc.
4. Much more.

These are a few of the major things that you need to keep in mind. Your code is correct, the problem is with authentication. Either the username/password is incorrect, otherwise Google is preventing your app to communicate.
