Java SpringBoot整合shiro-spring-boot-starterqi项目报错解决

Description:
The bean 'securityManager', defined in class path resource [org/apache/shiro/spring/config/web/autoconfigure/ShiroWebAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [com/ncwu/common/infrastructure/config/ShiroConfig.class] and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
