Description:

The bean 'channelFilter', defined in null, could not be registered. A bean with that name has already been defined in file [D:\321\demo2\target\classes\com\hzr\demo2\filter\ChannelFilter.class] and overriding is disabled.

Action:

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