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
java.lang.IllegalArgumentException: Request header is too large
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
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项目更方便了,在 application.properties 文件中添加
server.max-http-header-size=102400
