Request header is too large 的问题解决_spring boot request header is too large

问题原因

一个新增的接口，因为前端传入一段很长的JSON数组，导致了打印台报错

错误描述

java.lang.IllegalArgumentException: Request header is too large
1

解决方案

查阅了一下资料得到了一个答案

请求头超过了tomcat的限值。本来post请求是没有参数大小限制，但是服务器有自己的默认大小。

那就修改服务器的大小

• 普通tomcat
  在server.xml中 <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" maxPostSize="0" maxHttpHeaderSize ="102400"/>
  处加上maxHttpHeaderSize =”102400”

• SpringBoot
  SpringBoot项目更方便了，在application.properties文件中添加

server.max-http-header-size=102400
1
