java gmail imap_Javamail与Gmail的IMAP连接在随机持续时间后会丢失

我正在使用Javamail对gmail imap服务器进行身份验证,并一次获取一个完整邮箱的邮件头并在本地编制索引.对于消息很少的收件箱,这很好用.对于邮件通常超过10k的收件箱,javamail imap连接被删除(可能由服务器).需要注意的是,此持续时间是随机的.

由于我一个接一个地连续获取消息头,因此没有时间连接空闲很长时间,因此它不能是超时.

IMAPSSLStore imapSslStore = connectToImap(“imap.googlemail.com”,993,email,oauthToken,oauthTokenSecret,getMyConsumer(),true);

System.out.println(“Successfully authenticated to IMAP.\n”);

Folder inBox = imapSslStore.getFolder(“[Gmail]/All Mail”);

inBox.open(Folder.READ_ONLY);

Message messages[] = inBox.getMessages();

for(Message message:messages) {

System.out.println(message);

System.out.println(“MSG NO:”+message.getMessageNumber());

System.out.println(“FROM:”+message.getFrom().toString());

}
