Tomcat配置可能会导致URL中意外编码的异常

server.xml

URI编码为UTF-8，但是Tomcat将其解码为ISO-8859-1。您需要在server.xml中编辑连接器设置，并添加URIEncoding =“ UTF-8”属性。

<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"/>

application.yml

server:
  port: 25001
  tomcat:
    accesslog:
      enabled: true
    uri-encoding: UTF-8
