我已经配置了参数,也按网上不少教程操作过,还是不错.一直报这个错误,请教一下

开发环境配置

server:
max-http-header-size: 10000000

服务器的HTTP端口，默认为80

port: 443
servlet:
# 应用的访问路径
context-path: /

http: # 新加一个http的端口号配置
port: 8888

tomcat:
# tomcat的URI编码
uri-encoding: UTF-8
# tomcat最大线程数，默认为200
max-threads: 800
# Tomcat启动初始化的线程数，默认值25
min-spare-threads: 30
max-http-post-size: -1
# 单位 KB
max-http-header-size: 10000000

添加两个参数试试
maxPostSize="-1" maxHttpHeaderSize ="102400"
maxHttpHeaderSize ="102400"，大小可更加项目自行调整。
maxPostSize设置为-1，-1代表不限制，也可设置为某一固定值。
