Description:

The bean 'connectionFactory', defined in class path resource [org/xiaowu/behappy/common/r2dbc/config/R2dbcEntityTemplateConfigure.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/r2dbc/ConnectionFactoryConfigurations$Pool.class] and overriding is disabled.

Action:

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

I have to configure to allow java bean overrides(allow-bean-definition-overriding: true) ,is that right?

@a943915349 it looks like your custom configuration is part of an auto-configuration of some sort. If you want your customization to run, it should be ordered so that it runs before R2dbcAutoConfiguration. If you run after without a condition, you'll effectively override the bean, which is what this exception is warning you. If that code isn't part of an auto-configuration, please share a small sample that reproduces the problem (no code in text but a zip of a project or a link to a GitHub repo so that we can run it ourselves).
