我的 Web 应用程序出现了一些奇怪的行为，我似乎无法弄清楚发生了什么。
问题是，每当控制器响应时间超过一定时间时，由于某种原因它会重试（基于它花费的时间）。第一次尝试是上传文件，但随后注释掉了我的控制器中的所有内容，并且只有：
Thread.currentThread().sleep(60000);
我在日志中注意到，在线程完成之前，某些东西仍在持续发布请求。
我不确定这是否重要，但这是我的表格：
<form action="/w/upload" method="post" enctype="multipart/form-data" >
Select a file: <input type="file" name="videoFileData" />
<input type="submit" value="Upload" />
</form>
我测试了没有附加文件的 POST 并且它工作（控制器只收到 1 个请求），但是在请求中上传了一个文件，控制器收到了两个请求。
我是否缺少某种配置？
