我得到了一個表單，屬於一個web應用程序，其中包含一個用於上傳pdf文件的「文件」字段（彈簧3環境，多部分文件上傳） 上傳文件正常工作在測試環境（所有瀏覽器）中，並且只能在生產環境中使用Firefox（文件上傳導致連接重置異常，尤其是低互聯網連接客戶端瀏覽器）上傳文件問題彈簧3 - MultipartException，連接重置
提交按鈕被按下後幾秒鐘會拋出以下異常：瀏覽器是在Windows環境下運行的IE/Chrome，但不是Firefox）

可能是什麼該異常的可能的原因？
文件上傳的連接重置通常意味着客戶端中止發送......那麼是什麼？ 任何幫助將不勝感激。 Christophe D.
你可以發佈你的HTML表單，看起來像表單編碼的問題。 –
hi Jigar，剛剛編輯了這個線程，你現在可以看到html表單。謝謝。 –
我很確定你的生產服務器前面有一個防火牆/負載平衡器，即使你的應用服務器允許一個很大的上傳超時，它也會在一定的超時後終止連接。我會做的是在開發工具打開的情況下在生產環境中嘗試此操作，以查看上傳失敗後的時間。如果您注意到在每個瞬間失敗發生在x秒後，您知道您的基礎設施正在關閉連接。 – Akshay
