Annotation Interface ConditionalOnQualifiedBean

@Target({TYPE,METHOD}) @Retention(RUNTIME) @Documented @Conditional(OnQualifiedBeanCondition.class) public @interface ConditionalOnQualifiedBean
Conditional that only matches when for the specified bean class in the BeanFactory there is an instance which has the given qualifier set on it.

The condition can only match the bean definitions that have been processed by the application context so far and, as such, it is strongly recommended to use this condition on auto-configuration classes only. If a candidate bean may be created by another auto-configuration, make sure that the one using this condition runs after.
