Customer Statement Processor

There is some storage managed by the server, where user can upload customer statement files (xml or csv). Once file uploaded, a validation operation will be executed by the server to validate it.

Spring Batch Solution

The user can do the following:

• Upload customer statement file (xml or csv).
• Subscribe to Server-Sent Events.
• Get list of all uploaded files with summarized validation result.
• Get a full validation result for specific file.
• Delete specific file from storage.
