Class PostProcessorRegistrationDelegate.ApplicationListenerDetector

java.lang.Object

org.springframework.context.support.PostProcessorRegistrationDelegate.ApplicationListenerDetector

All Implemented Interfaces:

BeanPostProcessor, DestructionAwareBeanPostProcessor, MergedBeanDefinitionPostProcessor

Enclosing class:

PostProcessorRegistrationDelegate

private static class PostProcessorRegistrationDelegate.ApplicationListenerDetector
extends java.lang.Object
implements MergedBeanDefinitionPostProcessor, DestructionAwareBeanPostProcessor

BeanPostProcessor that detects beans which implement the ApplicationListener interface. This catches beans that can't reliably be detected by getBeanNamesForType.

Method Detail

postProcessMergedBeanDefinition

public void postProcessMergedBeanDefinition(RootBeanDefinition beanDefinition,
                                            java.lang.Class<?> beanType,
                                            java.lang.String beanName)

Description copied from interface: MergedBeanDefinitionPostProcessor

Post-process the given merged bean definition for the specified bean.

Specified by:

postProcessMergedBeanDefinition in interface MergedBeanDefinitionPostProcessor

Parameters:

beanDefinition - the merged bean definition for the bean

beanType - the actual type of the managed bean instance

beanName - the name of the bean

postProcessBeforeInitialization

public java.lang.Object postProcessBeforeInitialization(java.lang.Object bean,
                                                        java.lang.String beanName)

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.

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

See Also:

InitializingBean.afterPropertiesSet()

postProcessAfterInitialization

public java.lang.Object postProcessAfterInitialization(java.lang.Object bean,
                                                       java.lang.String beanName)

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.

Specified by:

postProcessAfterInitialization 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

See Also:

InitializingBean.afterPropertiesSet(), FactoryBean

postProcessBeforeDestruction

public void postProcessBeforeDestruction(java.lang.Object bean,
                                         java.lang.String beanName)

Description copied from interface: DestructionAwareBeanPostProcessor

Apply this BeanPostProcessor to the given bean instance before its destruction. Can invoke custom destruction callbacks.

Like DisposableBean's destroy and a custom destroy method, this callback just applies to singleton beans in the factory (including inner beans).

Specified by:

postProcessBeforeDestruction in interface DestructionAwareBeanPostProcessor

Parameters:

bean - the bean instance to be destroyed

beanName - the name of the bean
