java - 如何捕获嵌套的 SMTPAddressFailedException
问题描述
我的应用程序对电子邮件收件人有一个循环,其中一些人的地址可能不正确。当遇到坏的时候,我希望它报告给用户并继续循环。问题是即使我捕获了所有可能的异常,但 SMTPAddressFailedException 却被 javax 捕获:
javax.mail.SendFailedException:无效地址;嵌套异常是:com.sun.mail.smtp.SMTPAddressFailedException:550 5.1.1:收件人地址被拒绝:虚拟邮箱表中的用户未知
其余的收件人被跳过。处理这个问题的正确方法是什么?
这是代码;
List<Entry> theEntries = theConcours.GetEntriesList();
for(Entry entry : theEntries){
MasterPersonExt mp = aConcours.GetMasterPersonnelObject().GetMasterPerson(entry.GetOwnerUnique()) ;
String owneremail = mp.getEmail();
String ownername = mp.getFirstName() + " " + mp.getLastName();
curOwnerUniqueName = mp.getUniqueName();
System.out.println("Processing " + mp.getUniqueName() + " email: " + owneremail);
MimeMessage message = new MimeMessage(session);
try {
message.setFrom(new InternetAddress(mailuser));
System.out.println("From set while processing " + curOwnerUniqueName);
} catch (AddressException ex) {
String msg = "AddressException for: " + mailuser + " while processing " + curOwnerUniqueName;
//Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
okDialog(msg);
aConcours.GetLogger().log(Level.INFO, msg, ex);
continue;
} catch (MessagingException ex) {
// Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
String msg = "MessagingException for: " + mailuser + " while processing " + curOwnerUniqueName;
//Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
okDialog(msg);
aConcours.GetLogger().log(Level.INFO, msg, ex);
continue;
}
try {
message.setSubject("Your JCNA Concours Entry");
} catch (MessagingException ex) {
// Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
String msg = "MessagingException setting Subject while processing " + curOwnerUniqueName ;
//Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
okDialog(msg);
aConcours.GetLogger().log(Level.INFO, msg, ex);
continue;
}
InternetAddress ownerInternetAddr;
try {
ownerInternetAddr = new InternetAddress(owneremail);
} catch (AddressException ex) {
String msg = "Bad judge eMail address for " + curOwnerUniqueName + " \"" + mp.getEmail() + "\"";
okDialog(msg);
Logger.getLogger(SendMailSSL.class.getName()).log(Level.INFO, msg, ex);
continue;
}
try {
///
message.addRecipient(Message.RecipientType.TO, ownerInternetAddr);
} catch (MessagingException ex) {
// Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
String msg = "MessagingException setting TO while processing " + curOwnerUniqueName + " \"" + mp.getEmail() + "\"";
okDialog(msg);
Logger.getLogger(SendMailSSL.class.getName()).log(Level.INFO, msg, ex);
continue;
}
String ownerFirst = entry.GetOwnerFirst();
String entryplacard = "http://www.concoursbuilder.us/manual-uploads/" + theConcours.GetHostClub() + "/" + concoursName + "/Placards/" + entry.GetOwnerLast() + "_" + entry.GetUniqueDescription() + "-Placard.pdf";
String jagModel = entry.GetModel();
String[] theVals = {ownerFirst, jagModel, concoursName, judgingStarts, lunchTime,
awardsTime, concoursChairFirstLastName, concoursChairEmail, entryplacard, schedbyclass};
messageContent = replaceTagsWithValues(content_template, theTags, theVals);
try {
message.setContent(messageContent, "text/html; charset=utf-8");
} catch (MessagingException ex) {
//Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
String msg = "MessagingException setting Content while processing " + curOwnerUniqueName + " \"" + mp.getEmail() + "\"";
okDialog(msg);
Logger.getLogger(SendMailSSL.class.getName()).log(Level.INFO, msg, ex);
continue;
}
//send the message
try {
Transport.send(message);
System.out.println("message sent successfully...");
} catch (SMTPAddressFailedException ex){
String msg = "SMTPAddressFailedException while processing Owner " + ownername + " email address " + owneremail + " is invalid.";
System.out.println(msg);
okDialog(msg);
aConcours.GetLogger().log(Level.INFO, msg, ex);
continue;
} catch (MessagingException ex) {
// Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
String msg = "MessagingException while processing Owner " + ownername + " email address " + owneremail;
System.out.println(msg);
okDialog(msg);
aConcours.GetLogger().log(Level.INFO, msg, ex);
continue;
}
}
解决方案
我通过实现一个名为 sendMailToAnEntrant() 的辅助函数解决了这个问题。然后,for 循环在 try-catch 中对 sendMailToAnEntrant() 进行了一次调用。这会导致 javax 代码抛出的异常被捕获。似乎工作。
for(Entry entry : theEntries){
try {
//sendMailToAnEntrant(Concours aConcours, String aFromEmailAddress, String aSubject, String aContentTemplate, String [] aTags, Entry aEntry, Session aSession)
sendMailToAnEntrant(aConcours, mailuser, "Your JCNA Concours Entry", content_template, theTags, entry, session);
} catch (MessagingException ex) {
MasterPersonExt mp = aConcours.GetMasterPersonnelObject().GetMasterPerson(entry.GetOwnerUnique()) ;
String owneremail = mp.getEmail();
String ownername = mp.getFirstName() + " " + mp.getLastName();
String msg = "Messaging Exception in sendMailToAnEntrant() for: " + ownername + " Email: " + owneremail;
System.out.println(msg);
okDialog(msg);
aConcours.GetLogger().log(Level.INFO, msg, ex);
//Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
continue;
}
