java.lang.Objectorg.springframework.beans.factory.config.InstantiationAwareBeanPostProcessorAdapter
public abstract class InstantiationAwareBeanPostProcessorAdapter
Adapter implementing all methods on SmartInstantiationAwareBeanPostProcessor
as no-ops, which will not change normal processing of each bean instantiated
by the container. Subclasses may override merely those methods that they are
actually interested in.

Method Summary | |

Object |
postProcessAfterInitialization(Object bean,
String beanName)
Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet
or a custom init-method). |
boolean |
postProcessAfterInstantiation(Object bean,
String beanName)
Perform operations after the bean has been instantiated, via a constructor or factory method, but before Spring property population (from explicit properties or autowiring) occurs. |
Object |
postProcessBeforeInitialization(Object bean,
String beanName)
Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet
or a custom init-method). |
Object |
postProcessBeforeInstantiation(Class beanClass,
String beanName)
Apply this BeanPostProcessor before the target bean gets instantiated. |
PropertyValues |
postProcessPropertyValues(PropertyValues pvs,
PropertyDescriptor[] pds,
Object bean,
String beanName)
Post-process the given property values before the factory applies them to the given bean. |
Class |
predictBeanType(Class beanClass,
String beanName)
Predict the type of the bean to be eventually returned from this processor's InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class, java.lang.String) callback. |

InstantiationAwareBeanPostProcessor
If a non-null object is returned by this method, the bean creation process
will be short-circuited. The only further processing applied is the
BeanPostProcessor.postProcessAfterInitialization(java.lang.Object, java.lang.String)
callback from the configured
BeanPostProcessors
.
This callback will only be applied to bean definitions with a bean class. In particular, it will not be applied to beans with a "factory-method".
Post-processors may implement the extended
SmartInstantiationAwareBeanPostProcessor
interface in order
to predict the type of the bean object that they are going to return here.

Also allows for replacing the property values to apply, typically through creating a new MutablePropertyValues instance based on the original PropertyValues, adding or removing specific values.

The returned bean instance may be a wrapper around the original.
In case of a FactoryBean, this callback will be invoked for both the FactoryBean
instance and the objects created by the FactoryBean (as of Spring 2.0). The
post-processor can decide whether to apply to either the FactoryBean or created
objects or both through corresponding bean instanceof FactoryBean
checks.
This callback will also be invoked after a short-circuiting triggered by a
InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class, java.lang.String)
method,
in contrast to all other BeanPostProcessor callbacks.
