ImapMailReceiver在只读文件夹上没有存储尝试(失败)[已限制]； [英] ImapMailReceiver NO STORE attempt on READ-ONLY folder (Failure) [THROTTLED];
问题描述
我花了一天的时间来寻找这种例外的一些解释.我尝试以编程方式配置ImapMailReceiver和ImapIdleChannelAdapter.
I spend day trying to find some explanation this exception. I try to configure ImapMailReceiver and ImapIdleChannelAdapter programmatic.
在 Pro Spring Integration 书中，我仅找到少量有关该问题的教程.
I didn't find any tutorials about this question just small info in Pro Spring Integration book.
public void loadMessages() {
ImapIdleChannelAdapter imapIdleChannelAdapter = null;
ImapMailReceiver imapMailReceiver = null;
try {
imapMailReceiver = new ImapMailReceiver("imaps://" + URLEncoder.encode(USERNAME, "UTF-8") + ":" + PASSWORD + "@imap.gmail.com:993/INBOX");
imapMailReceiver.setShouldMarkMessagesAsRead(true);
imapMailReceiver.setShouldDeleteMessages(false);
Properties javaMailProperties = new Properties();
javaMailProperties.put(MAIL_IMAP_SOCKET_FACTORY_CLASS, environment.getProperty(MAIL_IMAP_SOCKET_FACTORY_CLASS, SOCKET_FACTORY_CLASS));
javaMailProperties.put(MAIL_IMAP_SOCKET_FACTORY_FALLBACK, environment.getProperty(MAIL_IMAP_SOCKET_FACTORY_FALLBACK, Boolean.class, SOCKET_FACTORY_FALLBACK));
javaMailProperties.put(MAIL_STORE_PROTOCOL, environment.getProperty(MAIL_STORE_PROTOCOL, INBOX_MAIL_PROTOCOL));
javaMailProperties.put(MAIL_DEBUG, environment.getProperty(MAIL_DEBUG, Boolean.class, MAIL_DEBUG_VAL));
imapMailReceiver.setJavaMailProperties(javaMailProperties);
imapMailReceiver.setJavaMailAuthenticator(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(USERNAME, PASSWORD);
}
});
ThreadPoolTaskScheduler threadPoolTaskScheduler = new ThreadPoolTaskScheduler();
threadPoolTaskScheduler.setPoolSize(environment.getProperty(RECEIVE_MESSAGE_POOL_SIZE, Integer.class, DEFAULT_RECEIVE_MESSAGE_POOL_SIZE));
threadPoolTaskScheduler.afterPropertiesSet();
DirectChannel directChannel = new DirectChannel();
directChannel.subscribe(new MessageHandler() {
@Override
public void handleMessage(Message<?> message) throws org.springframework.messaging.MessagingException {
LOGGER.info("Message: " + message);
}
});
imapIdleChannelAdapter = new ImapIdleChannelAdapter(imapMailReceiver);
imapIdleChannelAdapter.setAutoStartup(true);
imapIdleChannelAdapter.setShouldReconnectAutomatically(true);
imapIdleChannelAdapter.setTaskScheduler(threadPoolTaskScheduler);
imapIdleChannelAdapter.setOutputChannel(directChannel);
imapIdleChannelAdapter.start();
} catch (IllegalStateException iex){
LOGGER.debug("Receiving messages failed", iex);
iex.printStackTrace();
imapIdleChannelAdapter.stop();
try{
imapMailReceiver.destroy();
} catch (Exception ex){
LOGGER.debug("Impossible destroy imapMailReceiver", ex);
ex.printStackTrace();
}
} catch (UnsupportedEncodingException uex) {
LOGGER.debug("UnsupportedEncoding Exception", uex);
uex.printStackTrace();
}
}

我也找到了这样的决定

但是我不明白为什么人们使用这种方式来获取消息(该决定的主要来源，因为我什至无法在Spring Pro Integration和
But I can't understand why people use this way for getting messages (where the main source this decision because I can't even find this type of solution in Spring Pro Integration and Spring documentation )
请，任何人都可以向我解释 1)在这种情况下，我应该使用ImapIdleChannelAdapter，而当使用Session进行存储并连接到邮箱时. 2)为什么现在出现异常仅对只读文件夹不进行存储尝试"
Please, can anyone explain me 1)in which case I should use ImapIdleChannelAdapter and when just Session for getting store and connecting to mailbox. 2)Why do I get the exception 'NO STORE attempt on READ-ONLY folder' now
推荐答案
您应该调用imapMailReceiver.afterPropertiesSet()，这会切换this.folderOpenMode = Folder.READ_WRITE;.就您而言，它看起来就在这里:
You should call imapMailReceiver.afterPropertiesSet(), which switches this.folderOpenMode = Folder.READ_WRITE;. In your case it looks lie here:
imapMailReceiver.setJavaMailAuthenticator(new Authenticator() {
...
});
imapMailReceiver.afterPropertiesSet();
实际上，几乎所有的Spring Integration组件都应配置为Spring Bean，并且Container会注意它们的初始化.新的4.0版本为JavaConfig提供了足够的选项: https://spring.io/blog/2014/04/30/spring-integration-4-0-released .
Actually almost all Spring Integration components should be configured as Spring beans and Container will take care about their initialization. The new 4.0 version provides enough options for JavaConfig: https://spring.io/blog/2014/04/30/spring-integration-4-0-released .
我不清楚为什么默认情况下它是Folder.READ_ONLY，并且对此没有任何影响.
It's not clear to me why by default it is Folder.READ_ONLY and there is no setter on the matter.

在这种情况下，我应该使用ImapIdleChannelAdapter，而当使用Session进行存储并连接到邮箱时.
In which case I should use ImapIdleChannelAdapter and when just Session for getting store and connecting to mailbox.
实际上，这取决于您的邮件提供商. Spring Integration提供了两个组件:Pop3MailReceiver和ImapMailReceiver.当然，Imap更好，因为它不将消息提取到本地目录并支持Listener. Pop3，您应该定期ping通.
Actually it depends on your Mail provider. Spring Integration provides two components: Pop3MailReceiver and ImapMailReceiver. Of course Imap is better, because it doesn't fetch messages to the local directory and supports Listener. Pop3 you should ping periodically.
