How does spring-boot @ConditionalOnClass work?

Question

How exactly does the @ConditionalOnClass annotation work?

My goal is to load a specific bean only if the jar providing this class is included i

Answer 1

Good catch!

You can use on @Bean method level, but in that case you have to specify your class as a String literal:

@Bean
@ConditionalOnClass(name ="de.MyService")
public MyConditionalBean statistics() {
    return new MyConditionalBean();
}

I don't remeber already "why", but it is from an existing code of Spring Boot sources.
