看看https://tomcat.apache.org/tomcat-9.0-doc/config/http.html，我发现Tomcat Apache中标头大小的默认限制是8KB。
当我发出的标头超过默认8KB的请求时，日志显示以下内容：
Dec 30, 2019 1:59:26 PM org.apache.coyote.http11.Http11Processor service
INFO: Error parsing HTTP request header

我的Java项目在server.xml中没有/webapp/WEB-INF，只有web.xml。我尝试创建一个server.xml并添加以下内容，例如在此thread中所说的内容：
<?xml version='1.0' encoding='utf-8'?>
<Connector port="8080" protocol="HTTP/1.1" maxHttpHeaderSize="65536" maxPostSize="4194304"
URIEncoding="UTF-8"/>//webapp/WEB-INF
如何增加默认大小限制？我想设置16KB。
预先感谢=）
PS：我是Tomcat / Java World的新手，对不起，如果我犯了一个可怕的错误= p
