* GH-3653: Improve DSL parsing performance Fixes https://github.com/spring-projects/spring-integration/issues/3653 * Refactor `IntegrationFlowBeanPostProcessor` to perform `beanFactory.getBeansOfType()` as less as possible * Implement a `NamedComponent` on the `StandardIntegrationFlow` for better bean scanning performance in the `IntegrationFlowBeanPostProcessor` * * Skip `NamedComponent` from bean scanning if `beanName == null`
