这几天项目总是在凌晨挂机，查看日志发现以下错误：

Http11Processor - Error parsing HTTP request header
     Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

那么可能需要通过以下两种方式解决：

一、Tomcat的header缓冲区大小不够,只需要在server.xml中增加**maxHttpHeaderSize**字段即可:

如果是SpringBoot项目，则需要在application.yml文件中，进行如下修改：

server:
      port: 项目端口
      # 下面这个参数是为解决问题而新增的
      tomcat:
        max-http-header-size: 8192

二、可能是因为请求协议不对，需要统一成https或http请求。
