Tomcat maxThreads 更改不是 "catch"

Question

我的 server.xml 文件中有两个连接器:

<Connector protocol="HTTP/1.1" maxThreads="1" connectionTimeout="20000" redirectPort="8443" disableUploadTimeout="true" port="29171" />
<Connector protocol="AJP/1.3" maxThreads="1" redirectPort="8443" port="29172" />

我添加了 maxThreads="1"但似乎我仍然可以收到多个请求。我还尝试设置一个垃圾值(一个字符串)，但该服务仍会加载和处理请求。

我做错了什么？

谢谢

Answer 1

除了 maxThreads 参数外，还有 acceptCount，它是排队请求的大小。我认为默认值为 100。您可能需要将其设置为 1 或 0。但是您到底想在这里做什么/实现什么？
