Answer 1

you have multiple instances of RestClient beans defined in your configuration, and spring can't tell which of them you want to Autowire. when you annotate with @Bean give it a name as a parameter and then you need to add @Qualifier annotations to all autowired members of the same class (or extending) as RestClient, and specify which bean name you want for each autowired member.
