Description
When I add @RefreshScope on a bean (such as bean ‘myBean’) as well as @ConditionOnMissingBean(A.class), though A.class and bean a is in spring container, the bean 'myBean' always loaded in spring ,the @ConditionOnMissingBean likes unaviable . But I remove @RefreshScope, it works normal and the bean 'myBean' is not loader in spring.
this is my code
springboot version is 3.3.4,cloud-config version is 4.1.2
`
@SpringBootApplication
public class ReactiveApplication {
public static void main(String[] args) {
SpringApplication.run(ReactiveApplication.class);
}
@ConditionalOnMissingBean(ReactiveApplication.class)
@RefreshScope
@Component
public static class TestConfig {
static {
System.out.println("TestConfig class loaded");
}
}
}
`
ReactiveApplication is main springboot class, so it is always loaded in spring, so normally @ConditionalOnMissingBean is uneffective and TestConfig is not loaded. But actually TestConfig was loaded and print “TestConfig class loaded”. However, When remove "@RefreshScope", it was normal and not print "TestConfig class loaded".
I just think the all anonation like @Conditionxxx is unavaiable with RefreshScope, but when I use @ConditonOnProperty and @ConditionalOnMissingClass, it works normally. Why?

Research direction
Reproduce the supplied ReactiveApplication example with Spring Boot 3.3.4 and Spring Cloud Config 4.1.2, comparing bean registration with and without @RefreshScope. Start by tracing how @RefreshScope and @ConditionalOnMissingBean process TestConfig and ReactiveApplication; done means explaining the differing behavior and identifying a focused regression test or fix.
