Załaduj problem z plikiem z wiosną 3 - Wyjątek MultipartException, zerowanie połączenia

Question

Mam formularz należący do aplikacji internetowej, która zawiera pole "plik" do przesłania pliku pdf. (Wiosna, środowisko, przesyłanie wielu plików) Przesyłanie pliku działa dobrze w środowisku testowym (wszystkie przeglądarki) i działa tylko z Firefoksem w środowisku produkcyjnym (przesyłanie plików powoduje, że wyjątek resetowania połączenia jest szczególnie niski)

Poniższy wyjątek jest zgłaszany kilka sekund po naciśnięciu przycisku przesyłania: (przeglądarka to IE/Chrome działająca w środowisku Windows, ale nie Firefox)

co mogłoby być możliwe przyczyny tego wyjątku ?
Reset połączenia podczas przesyłania pliku oznacza zwykle, że klient przerwał wysyłanie ... co z tego? Każda pomoc byłaby doceniana. Christophe D.

Answer 1

Czy można przechwycić tcpdump między klientem a serwerem i zobaczyć, kto resetuje połączenie. Podobny problem wystąpił w naszej aplikacji i był to firewall, który zrzucał połączenie. Było jeszcze inne ustawienie w Apache [LimitRequestBody], które przerywało przesyłanie po tym, jak przesyłanie plików osiągnęło ten limit. Dzienniki z apache i mod-jk w tych dwóch przypadkach nie były zbyt jasne do debugowania w tych scenariuszach.
