Question

我正在尝试使用java邮件发送电子邮件通知程序。我能够向多个收件人发送邮件，但有多个主题。比如说。我正在向圣何塞用户发送未注册设备的数量，它应该将主题作为“未注册的圣何塞设备”，如果是Boulder用户则应该是'未注册的Boulder设备'。这是主要方法。公共类EmailNotifier实现Job {

private static Map<String,String>Site_names=new HashMap<String,String>();
private static Map<String,String> hostName_EmailAlias = new HashMap<String,String>();
private static Properties emailProperties;
private static Session mailSession;
private static MimeMessage emailMessage;

static {
   hostName_EmailAlias.put("gigantic-6", "prvaidee@yahoo.com");
    hostName_EmailAlias.put("ccm-sjcvtg-091", "vp@yahoo.com");
   Site_names.put("gigantic-6", "UnRegistered Devices for San Jose");
   Site_names.put("ccm-sjcvtg-091", "UnRegistered Devices for Pre-Alpha");

     public void createSendEmailMessage(QueryDataObject dataObj) throws AddressException,
        MessagingException, JobExecutionException {

    String emailPort = "25";
    String emailHost = "outbound.xxxxx.com";

    emailProperties = System.getProperties();
    emailProperties.put("mail.smtp.host", emailHost);
    emailProperties.put("mail.smtp.port", emailPort);

    emailProperties.put("mail.smtp.auth", "true");
    emailProperties.put("mail.smtp.starttls.enable", "false");

    String emailSubject = Site_names.get( "gigantic-6");
    String emailSubject1=Site_names.get( "ccm-sjcvtg-091");


    mailSession = Session.getDefaultInstance(emailProperties, null);
    emailMessage = new MimeMessage(mailSession);

              emailMessage.addRecipient(Message.RecipientType.TO,   new InternetAddress(dataObj.getEmailAlias()));

    emailMessage.setSubject(emailSubject,emailSubject1);
    emailMessage.setContent(dataObj.getEmailBody(), "text/html");// for a html email

    Transport transport = mailSession.getTransport("smtp");
        transport.connect(emailHost,emailSubject.emailSubject1);
    //transport.connect(emailHost, fromUser, fromUserEmailPassword);
    transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
    transport.close();

    System.out.println("Email sent successfully.");

}

我创建了2个地图，一个用于差异收件人的不同主机名，另一个用于差异主题（Sitenames）。我创建了2个字符串，其中包含emailSubject和emailSubject1.I我不知道如何将每个主机名和邮件与相应的主题相关联。我不是要求完整的代码帮助。任何指针或想法都会有所帮助。

Answer 1

主题实际上是信息正文的一部分。您不能向多个收件人发送单个邮件，也不能更改每个收件人的内容。

对于每个不同的内容（包括主题），您必须创建单独的消息。如果该不同内容有多个收件人，则可以将该一封邮件发送给这些多个收件人。

多个主题到java邮件中的多个收件人
