ConditionalOnMissingBean by class and name

I want to create bean when specific class type with specific name is missing, but ConditionalOnMissingBean below does not work, since value and name are not related.

@ConditionalOnMissingBean(value=BeanName.class, name = "beanName")

There is no such functionality of the box. However, you can easily implement it with custom Conditional:

class MyCondition implements Condition {
    @Override
    public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {

      String[] beanNames = context.getBeanFactory().getBeanNamesForType(BeanName.class);

      return Stream.of(beanNames).anyMatch(beanName -> beanName.equals("beanName"));
    }
  }

and add it to your bean @Conditional(MyCondition.class)
