应用程序引擎邮件未发送 [英] app engine mail is not sending

问题描述

我有App引擎应用程序。

我有一个名为 push 的servlet。我部署了应用程序并调用了我的servlet GET方法。

在我的servlet中，我有两个方法：

1）首先是：（该方法不发送邮件，我不明白为什么？我没有错误）

  void sendMail （）抛出UnsupportedEncodingException {
 
属性props = new Properties（）; 
 Session session = Session.getDefaultInstance（props，null）; 
 String msgBody =TEXT HERE; 
尝试{
消息msg = new MimeMessage（session）; 
 msg.setFrom（新InternetAddress（ownerMail，Example.com Admin））; 
 msg.addRecipient（Message.RecipientType.TO，new InternetAddress（[e-mail]，Mr. User））; 
 msg.setSubject（您的PDF有问题）; 
 msg.setText（msgBody）; 
 $ b $ catch（AddressException e）{
 log（error，e）; 
} catch（MessagingException e）{
 log（error，e）; 
} 
 
} 
  

我也调用另一种方法： （这是有效的！）

void snedTest（）{

  String to =somebody; 
来自=ownerMail的字符串; 
 String host =localhost：8080; 
属性properties = System.getProperties（）; 
 properties.setProperty（mail.smtp.host，host）; 
 Session session = Session.getDefaultInstance（properties）; 
 
尝试{
 
 MimeMessage message = new MimeMessage（session）; 
 message.setFrom（new InternetAddress（from））; 
 message.addRecipient（Message.RecipientType.TO，new InternetAddress（to））; 
 message.setSubject（This is the Line Line！）; 
 message.setText（This is actual message）; 
 Transport.send（message）; 
 System.out.println（发送邮件成功....）; 
} catch（MessagingException mex）{
 mex.printStackTrace（）; 
} 
  

}

第一种方法不起作用！我不知道为什么？我在LOG中没有错误。但是第二种方法可行。

解决方案

哦，我没有

  Transport.send（message）; 
  

I have App engine Application.

I have one servlet named push. I deploy me application and call my servlets GET method.

In My servlet, I have two methind:

1) first is that: (that method does not send mails. I dont undestand why? I have no errors)

void sendMail() throws UnsupportedEncodingException{

        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);
        String msgBody = "TEXT HERE";
        try {
            Message msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress("ownerMail","Example.com Admin"));
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress("[e-mail]", "Mr. User"));
            msg.setSubject("YOUR PDF HAVE PROBLEMS");
            msg.setText(msgBody);

        } catch (AddressException e) {
            log("error", e);
        } catch (MessagingException e) {
            log("error", e);
        }

}

and I call another method too: (this works!)

void snedTest(){

String to = "somebody";
String from = "ownerMail";
String host = "localhost:8080";
Properties properties = System.getProperties();
properties.setProperty("mail.smtp.host", host);
Session session = Session.getDefaultInstance(properties);

try {

    MimeMessage message = new MimeMessage(session);
    message.setFrom(new InternetAddress(from));
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
    message.setSubject("This is the Subject Line!");
    message.setText("This is actual message");
    Transport.send(message);
    System.out.println("Sent message successfully....");
} catch (MessagingException mex) {
    mex.printStackTrace();
}

}

first method does not work! I don't know why? I have no error in LOG. But the second method works.

解决方案

OH, I did not have

 Transport.send(message);
