Annotation Type Conditional

@Retention(value=RUNTIME)
 @Target(value={TYPE,METHOD})
public @interface Conditional

Indicates that a component is is only eligible for registration when all specified conditions match.

A condition is any state that can be determined programmatically immediately before the bean is due to be created (see Condition for details).

The @Conditional annotation may be used in any of the following ways:

• as a type-level annotation on any class directly or indirectly annotated with @Component, including @Configuration classes
• as a meta-annotation, for the purpose of composing custom stereotype annotations
• as a method-level annotation on any @Bean method

If a @Configuration class is marked with @Conditional, all of the @Bean methods and @Import annotations associated with that class will be subject to the conditions.
