org.springframework.beans.factory.support.ChildBeanDefinition
public class ChildBeanDefinition
Bean definition for beans which inherit settings from their parent. Child bean definitions have a fixed dependency on a parent bean definition.
A child bean definition will inherit constructor argument values, property values and method overrides from the parent, with the option to add new values. If init method, destroy method and/or static factory method are specified, they will override the corresponding parent settings. The remaining settings will always be taken from the child definition: depends on, autowire mode, dependency check, singleton, lazy init.
NOTE: Since Spring 2.5, the preferred way to register bean
definitions programmatically is the GenericBeanDefinition
class,
which allows to dynamically define parent dependencies through the
GenericBeanDefinition.setParentName(java.lang.String)
method. This effectively
supersedes the ChildBeanDefinition class for most use cases.
