事故现场：

The bean 'beanNameViewResolver', defined in class path resource [cn/afterturn/easypoi/configuration/EasyPoiAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/error/ErrorMvcAutoConfiguration$WhitelabelErrorViewConfiguration.class] and overriding is disabled.

Action:

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

Process finished with exit code 1

解决办法：

在yml文件添加main配置即可解决

spring:

  application:

    name: SpringBoot_easyPOI

  main:

    allow-bean-definition-overriding: true
