很明显的重名错误，解决方式有两种：1.取别名；2.添加配置

***************************
APPLICATION FAILED TO START
***************************

Description:

The bean 'hiddenHttpMethodFilter', defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [com/example/test/config/WebMvcConfig.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

在配置文件中添加：即可

spring:
  main:
    allow-bean-definition-overriding: true

完美解决
