Error parsing HTTP request header Note: further occurrences of HTTP header parsing errors

tomcat进行http request解析的时候报错，并将错误返回给客户端了，具体的错误如下：org.apache.coyote.http11.AbstractHttp11Processor.processError parsing HTTP request headerNote:further occurrences of HTTP header parsing errors will be logged at DEBUG level.
就会报iib.requestheadertoolarge.error即Request header is too large，在网上搜索时，有的是因为这个设置导致的400，解决方法就是修改Tomcat的server.xml，在<Connectorport="8080"protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" />的配置中增加maxHttpHeaderSize的配置。
   <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" maxHttpHeaderSize="8192" />
    <!-- A "Connector" using the shared thread pool-->
    <!--
    <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    -->
    <!-- Define a SSL/TLS HTTP/1.1 Connector on port 8443

         style configuration. When using the APR/native implementation, the
