这在以前的Tomcat服务器(8.0.5)中没有发生.有修复吗？

注意:在我之前的问题(一年前)中,我禁用了HTTP监视器以禁止警告.这不是一个解决方案.

_{编辑:我忘了提及但很明显,在Filter关于Spring Security的s在web.xml中注册后出现此警告.}

Answer 1

这是使用 HttpMonitor 进行调试时的一个已知的 NB 错误：

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

HttpMonitor 可以工作，但如果请求的某些部分之前由 spring 处理（如 spring 安全链），它将跳过它们

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