Question

我正在尝试向用户发送电子邮件。我已经使用了javax.mail。*和javax.mail.internet。*包并成功发送了一封电子邮件，但问题是它正在为一个邮件ID发送多封电子邮件。我怎样才能让它只发送一次？

我的代码：

public void sendEmail(){

     System.out.println("called "+j+" time"); 

     emailIDs.add(emailID);

     to = emailID;

     MimeMessage message = new MimeMessage(session1);

     // Set From: header field of the header.
     try {

         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(notifyName[j]+" "+"Document Alert Mail!");

         // Send the actual HTML message, as big as you like

         message.setContent("<h1>document created on "+createdOn+" is coming to expire</h1>",
                            "text/html" );

         // Send message
         Transport.send(message);

         System.out.println("Message Sent Successfully....");
     }

     catch(Exception e){

         e.printStackTrace();
     }
 }

你应该在你的函数中提供参数。您调用emailID函数时似乎已多次添加sendEmail()元素。每次调用该函数时，都应该清理emailIDs或者只需要向最后一个元素发送电子邮件。

这里我只发送一个收件人：

public void sendEmail(String emailID){

 System.out.println("called "+j+" time"); 

 emailIDs.add(emailID);

     to = emailID;

     MimeMessage message = new MimeMessage(session1);

     // Set From: header field of the header.
     try{

     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(notifyName[j]+" "+"Document Alert Mail!");

     // Send the actual HTML message, as big as you like

     message.setContent("<h1>document created on "+createdOn+" is coming to expire</h1>",
                        "text/html" );

     // Send message
     Transport.send(message);

     System.out.println("Message Sent Successfully....");
     }

     catch(Exception e){

         e.printStackTrace();
     }
}
