Class DisposableBeanAdapter

java.lang.Object
  org.springframework.beans.factory.support.DisposableBeanAdapter

All Implemented Interfaces:

java.io.Serializable, java.lang.Runnable, DisposableBean

 class DisposableBeanAdapter
extends java.lang.Object
implements DisposableBean, java.lang.Runnable, java.io.Serializable

Adapter that implements the DisposableBean and Runnable interfaces performing various destruction steps on a given bean instance:

• DestructionAwareBeanPostProcessors;
• the bean implementing DisposableBean itself;
• a custom destroy method specified on the bean definition.

Constructor Detail

DisposableBeanAdapter

public DisposableBeanAdapter(java.lang.Object bean,
                             java.lang.String beanName,
                             RootBeanDefinition beanDefinition,

                             java.security.AccessControlContext acc)

Create a new DisposableBeanAdapter for the given bean.

Parameters:

bean - the bean instance (never null)

beanName - the name of the bean

beanDefinition - the merged bean definition

postProcessors - the List of BeanPostProcessors (potentially DestructionAwareBeanPostProcessor), if any

DisposableBeanAdapter

private DisposableBeanAdapter(java.lang.Object bean,
                              java.lang.String beanName,
                              boolean invokeDisposableBean,

                              java.util.List<DestructionAwareBeanPostProcessor> postProcessors)

Create a new DisposableBeanAdapter for the given bean.

Method Detail

filterPostProcessors

private java.util.List<DestructionAwareBeanPostProcessor> filterPostProcessors(java.util.List<BeanPostProcessor> postProcessors)

Search for all DestructionAwareBeanPostProcessors in the List.

Parameters:

postProcessors - the List to search

Returns:

the filtered List of DestructionAwareBeanPostProcessors

run

public void run()

Specified by:

run in interface java.lang.Runnable

destroy

public void destroy()

Description copied from interface: DisposableBean

Invoked by a BeanFactory on destruction of a singleton.

Specified by:

destroy in interface DisposableBean

determineDestroyMethod

private java.lang.reflect.Method determineDestroyMethod()

findDestroyMethod

private java.lang.reflect.Method findDestroyMethod()

invokeCustomDestroyMethod

private void invokeCustomDestroyMethod(java.lang.reflect.Method destroyMethod)

Invoke the specified custom destroy method on the given bean.

This implementation invokes a no-arg method if found, else checking for a method with a single boolean argument (passing in "true", assuming a "force" parameter), else logging an error.

writeReplace

protected java.lang.Object writeReplace()

Serializes a copy of the state of this class, filtering out non-serializable BeanPostProcessors.
