Class LoadTimeWeaverAwareProcessor

java.lang.Object

org.springframework.context.weaving.LoadTimeWeaverAwareProcessor

All Implemented Interfaces:

Aware, BeanFactoryAware, BeanPostProcessor

public class LoadTimeWeaverAwareProcessor
extends Object
implements BeanPostProcessor, BeanFactoryAware

BeanPostProcessor implementation that passes the context's default LoadTimeWeaver to beans that implement the LoadTimeWeaverAware interface.

Application contexts will automatically register this with their underlying bean factory, provided that a default LoadTimeWeaver is actually available.

Applications should not use this class directly.

Since:

2.5

Constructor Detail

LoadTimeWeaverAwareProcessor

public LoadTimeWeaverAwareProcessor()

Create a new LoadTimeWeaverAwareProcessor that will auto-retrieve the LoadTimeWeaver from the containing BeanFactory, expecting a bean named "loadTimeWeaver".

LoadTimeWeaverAwareProcessor

public LoadTimeWeaverAwareProcessor(@Nullable
                                    LoadTimeWeaver loadTimeWeaver)

Create a new LoadTimeWeaverAwareProcessor for the given LoadTimeWeaver.

If the given loadTimeWeaver is null, then a LoadTimeWeaver will be auto-retrieved from the containing BeanFactory, expecting a bean named "loadTimeWeaver".

Parameters:

loadTimeWeaver - the specific LoadTimeWeaver that is to be used

LoadTimeWeaverAwareProcessor

public LoadTimeWeaverAwareProcessor(BeanFactory beanFactory)

Create a new LoadTimeWeaverAwareProcessor.

The LoadTimeWeaver will be auto-retrieved from the given BeanFactory, expecting a bean named "loadTimeWeaver".

Parameters:

beanFactory - the BeanFactory to retrieve the LoadTimeWeaver from

Method Detail

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

Description copied from interface: BeanFactoryAware

Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:

setBeanFactory in interface BeanFactoryAware

Parameters:

beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

BeanInitializationException

postProcessBeforeInitialization

public Object postProcessBeforeInitialization(Object bean,
                                              String beanName)
                                       throws BeansException

Description copied from interface: BeanPostProcessor

Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

The default implementation returns the given bean as-is.

Specified by:

postProcessBeforeInitialization in interface BeanPostProcessor

Parameters:

bean - the new bean instance

beanName - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked

Throws:

BeansException - in case of errors

InitializingBean.afterPropertiesSet()

postProcessAfterInitialization

public Object postProcessAfterInitialization(Object bean,
                                             String name)

Description copied from interface: BeanPostProcessor

Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property 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.

The default implementation returns the given bean as-is.

Specified by:

postProcessAfterInitialization in interface BeanPostProcessor

Parameters:

bean - the new bean instance

name - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
