Question

我的网络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。

问题在于，无论何时控制器需要超过一定的时间来响应，由于某种原因它会重试（基于它花了多长时间）。第一次尝试是使用文件上传，但随后在我的控制器中注释掉所有内容并且只有：

Thread.currentThread().sleep(60000);

我在日志中注意到，在线程完成之前，某些内容仍在持续POST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NO文件的POSTing并且它有效（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。

我错过了某种配置吗？

好的，所以人们都知道。这是一个Jetty问题，可能是一个bug。切换到Tomcat解决了它。

为什么Spring MVC会自动重试POST请求？
