Tải lên sự cố tệp với spring 3 - MultipartException, thiết lập lại kết nối

Question

Tôi nhận được biểu mẫu thuộc ứng dụng web có chứa một tệp "" để tải lên tệp pdf. (Môi trường mùa xuân 3, tải lên nhiều tệp) Tải lên tệp hoạt động tốt trong môi trường thử nghiệm (tất cả các trình duyệt), và chỉ hoạt động với Firefox trong môi trường sản xuất (tải lên tệp gây ra ngoại lệ kết nối lại với trình duyệt web kết nối internet thấp đặc biệt)

Ngoại lệ sau đây được ném một vài giây sau khi nhấn nút gửi: (trình duyệt là IE/Chrome chạy trong môi trường windows nhưng không phải Firefox)

gì có thể là lý do có thể ngoại lệ này ?
Đặt lại kết nối khi tải lên tệp thường có nghĩa là khách hàng đã hủy gửi ... vì vậy, điều gì? Bất kỳ Trợ giúp nào sẽ được đánh giá cao. Christophe D.

Answer 1

Bạn có thể chụp tcpdump giữa máy khách và máy chủ và xem ai đang đặt lại kết nối. Chúng tôi đã có một vấn đề tương tự trong ứng dụng của chúng tôi và nó là một bức tường lửa đã bị ngắt kết nối. Có một cài đặt khác trong apache [LimitRequestBody] đã hủy tải lên sau khi tải lên tệp đạt đến giới hạn đó. Các bản ghi từ apache và mod-jk trong hai trường hợp này không rõ ràng để gỡ lỗi trong các kịch bản này.
