这在以前的Tomcat服务器(8.0.5)中没有发生.有解决办法吗?

This did not happen in the previous Tomcat server (8.0.5). Is there a fix?

注意:(一年前)在我的上一个问题中，我禁用了HTTP监视器，只是禁止了该警告.这不是解决方案.

Note : In my previous question (a year ago), I disabled the HTTP monitor to just suppress the warning. It was not a solution.

我忘了提一下，但是很明显，在Web.xml中注册了与Spring Security有关的Filter之后，会出现此警告.

EDIT : I forgot to mention but it is clear that this warning appears after Filters pertaining to Spring Security are registered in web.xml.

推荐答案

使用HttpMonitor进行调试时，这是一个已知的NB错误:

It's a known NB bug when using HttpMonitor for debugging:

https://netbeans.org/bugzilla/show_bug.cgi?id=204775

HttpMonitor可以工作，但是如果在Spring之前处理过请求，则会跳过请求的某些部分(例如spring安全链)

HttpMonitor will work but it is going to skip some parts of a request if they are processed before by spring (like spring security chain)

您可以尝试给Spring Security过滤器一个极高的顺序，并希望它能起作用，我对此表示怀疑.

You can try to give Spring Security filter an extremely high order and wish it works, which I doubt.
