看下网上的解决方案：
（1）原因是Tomcat的header缓冲区大小不够，只需要在 server.xml 中增加 maxHttpHeaderSize 字段即可：
<Connector connectionTimeout="20000" maxHttpHeaderSize="10000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
我是在 SpringBoot 中的配置文件添加了：
server.max-http-header-size=16KB
（2）头部包含了特殊字符的原因：
Tomcat 7.0.81以上支持，打开conf/catalina.properties在底部将
#tomcat.util.http.parser.HttpParser.requestTargetAllow=|
修改为
tomcat.util.http.parser.HttpParser.requestTargetAllow=|,{,}
