 Regular dependencies on other components always have precedence. In that sense, self
 references do not participate in regular candidate selection and are therefore in
 particular never primary. On the contrary, they always end up as lowest precedence.

+Trying to inject the results from `@Bean` methods on the same configuration class is

 You can create your own custom qualifier annotations. To do so, define an annotation and
 provide the `@Qualifier` annotation within your definition, as the following example shows:
