Interface LazyInitializationExcludeFilter

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface LazyInitializationExcludeFilter

Filter that can be used to exclude beans definitions from having their lazy-init set by the LazyInitializationBeanFactoryPostProcessor.

Primarily intended to allow downstream projects to deal with edge-cases in which it is not easy to support lazy-loading (such as in DSLs that dynamically create additional beans). Adding an instance of this filter to the application context can be used for these edge cases.

A typical example would be something like this:

 @Bean
 public static LazyInitializationExcludeFilter integrationLazyInitializationExcludeFilter() {
   return LazyInitializationExcludeFilter.forBeanTypes(IntegrationFlow.class);
 }
 

NOTE: Beans of this type will be instantiated very early in the spring application lifecycle so they should generally be declared static and not have any dependencies.

Since:

2.2.0
