java - 为什么 Spring MVC 自动重试 POST 请求？

Question

我的网络应用程序出现一些奇怪的行为，我似乎无法弄清楚发生了什么。

问题是，每当 Controller 花费超过一定时间来响应时，由于某种原因它会重试(基于花费的时间)。第一次尝试是上传文件，但随后注释掉了我的 Controller 中的所有内容，并且只有:

Thread.currentThread().sleep(60000);

我在日志中注意到有些东西仍在连续发布请求，直到线程完成。

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>

我在没有附加文件的情​​况下测试了 POSTing，它有效( Controller 仅收到 1 个请求)，但在请求中上传了一个文件后， Controller 收到了两个请求。

我是否缺少某种配置？

好的，让人们知道。那是一个 Jetty 问题，可能是一个错误。切换到 Tomcat 解决了它。
