public class DefaultListableBeanFactory
Default implementation of the
ListableBeanFactory
and
BeanDefinitionRegistry
interfaces: a full-fledged bean factory
based on bean definition objects.
Typical usage is registering all bean definitions first (possibly read from a bean definition file), before accessing beans. Bean definition lookup is therefore an inexpensive operation in a local bean definition table, operating on pre-built bean definition metadata objects.
Can be used as a standalone bean factory, or as a superclass for custom
bean factories. Note that readers for specific bean definition formats are
typically implemented separately rather than as bean factory subclasses:
see for example PropertiesBeanDefinitionReader
and
XmlBeanDefinitionReader
.
For an alternative implementation of the
ListableBeanFactory
interface,
have a look at StaticListableBeanFactory
, which manages existing
bean instances rather than creating new ones based on bean definitions.

Default is "true".
registerBeanDefinition(java.lang.String, org.springframework.beans.factory.config.BeanDefinition)
public void setAllowEagerClassLoading(boolean allowEagerClassLoading)
Default is "true". Turn this flag off to suppress class loading for lazy-init beans unless such a bean is explicitly requested. In particular, by-type lookups will then simply ignore bean definitions without resolved class name, instead of loading the bean classes on demand just to perform a type check.

Depending on the nature of the concrete bean factory implementation, this operation might be expensive (for example, because of directory lookups in external registries). However, for listable bean factories, this usually just amounts to a local hash lookup: The operation is therefore part of the public interface there. The same implementation can serve for both this template method and the public interface method in that case.
