How to solve the error 405 when Springboot uses put and delete requests

Springboot uses put and delete requests to report errors

SpringBoot has automatically configured HiddenHttpMethodFilter for us, but recently I found that it seems that it cannot be used. The SpringBoot version I am using is 2.2.2, and the default configuration has been changed to false. , that is, automatic configuration is turned off. I don’t know what sprongboot is. It’s a trap! ! !

There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'POST' not supported
org.springframework.web.HttpRequestMethodNotSupportedException: Request method ' POST' not supported

To change the springboot configuration yml file to

spring:
  mvc:
   hiddenmethod:
      filter:
        enabled: true

Springboot error prompt 405 status
