Web アプリケーションで奇妙な動作が発生し、何が起こっているのかわかりません。
問題は、コントローラーが応答するのに一定の時間を超えると、何らかの理由で (応答時間に基づいて) 再試行することです。最初の試みはファイルのアップロードでしたが、コントローラーのすべてをコメントアウトし、次のもののみを作成しました。
Thread.currentThread().sleep(60000);
スレッドが完了するまで、何かがまだリクエストを継続的に POST していることにログで気付きました。
それが重要かどうかはわかりませんが、ここに私のフォームがあります：
<form action="/w/upload" method="post" enctype="multipart/form-data" >
Select a file: <input type="file" name="videoFileData" />
<input type="submit" value="Upload" />
</form>
ファイルを添付せずに POSTing をテストしたところ、機能しました (コントローラーは 1 つの要求しか受信しませんでした) が、要求でファイルがアップロードされた場合、コントローラーは 2 つの要求を受け取りました。
ある種の設定がありませんか？
