public abstract class AbstractPrototypeBasedTargetSource extends AbstractBeanFactoryBasedTargetSource
Base class for dynamicTargetSourceimplementations that create new prototype bean instances to support a pooling or new-instance-per-invocation strategy.Such TargetSources must run in a
BeanFactory, as it needs to call thegetBeanmethod to create a new prototype instance. Therefore, this base class extendsAbstractBeanFactoryBasedTargetSource.- 作者:

setBeanFactory
public void setBeanFactory(BeanFactory beanFactory) throws BeansException
从类复制的说明:AbstractBeanFactoryBasedTargetSourceSet the owning BeanFactory. We need to save a reference so that we can use thegetBeanmethod on every invocation.- 指定者:
setBeanFactory在接口中BeanFactoryAware- 覆盖:
setBeanFactory在类中AbstractBeanFactoryBasedTargetSource- 参数:
beanFactory- owning BeanFactory (nevernull). The bean can immediately call methods on the factory.- 抛出:
BeansException- in case of initialization errors- 另请参阅:
BeanInitializationException
newPrototypeInstance
protected Object newPrototypeInstance() throws BeansException
Subclasses should call this method to create a new prototype instance.- 抛出:
BeansException- if bean creation failed
destroyPrototypeInstance
protected void destroyPrototypeInstance(Object target)
Subclasses should call this method to destroy an obsolete prototype instance.- 参数:
target- the bean instance to destroy
writeReplace
protected Object writeReplace() throws ObjectStreamException
Replaces this object with a SingletonTargetSource on serialization. Protected as otherwise it won't be invoked for subclasses. (ThewriteReplace()method must be visible to the class being serialized.)With this implementation of this method, there is no need to mark non-serializable fields in this class or subclasses as transient.
