java - 如何在一定时间后停止tomcat处理请求？

Question

我的 tomcat 服务器持续处理某些请求超过 10 分钟。我停止了触发这些请求的客户端，但随后 tomcat 也继续处理这些请求。

我在 tomcat 的 server.xml 文件中尝试了 connectionTimeout 属性的不同设置，但它不起作用。

我想知道如何配置 tomcat，以便 tomcat 杀死/停止处理花费超过特定时间(如 10 秒或 1 分钟等)的请求。

JK can also use a timeout on request replies. This timeout does not measure the full processing time of the response. Instead it controls, how much time between consecutive response packets is allowed.

In most cases, this is what one actually wants. Consider for example long running downloads. You would not be able to set an effective global reply timeout, because downloads could last for many minutes. Most applications though have limited processing time before starting to return the response. For those applications you could set an explicit reply timeout. Applications that do not harmonise with reply timeouts are batch type applications, data warehouse and reporting applications which are expected to observe long processing times.

If JK aborts waiting for a response, because a reply timeout fired, there is no way to stop processing on the backend. Although you free processing resources in your web server, the request will continue to run on the backend - without any way to send back a result once the reply timeout fired.
