public abstract class AbstractBeanFactoryBasedTargetSourceCreator extends Object implements TargetSourceCreator, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.DisposableBean
TargetSourceCreator
implementations that require creating multiple instances of a prototype bean.
Uses an internal BeanFactory to manage the target instances, copying the original bean definition to this internal factory. This is necessary because the original BeanFactory will just contain the proxy instance created through auto-proxying.
Requires running in an
AbstractBeanFactory.

AbstractBeanFactoryBasedTargetSourceCreator() |
| Modifier and Type | Method and Description |
|---|---|
protected org.springframework.beans.factory.support.DefaultListableBeanFactory |
buildInternalBeanFactory(org.springframework.beans.factory.config.ConfigurableBeanFactory containingFactory)
Build an internal BeanFactory for resolving target beans.
|
protected abstract AbstractBeanFactoryBasedTargetSource |
createBeanFactoryBasedTargetSource(Class<?> beanClass,
String beanName)
Subclasses must implement this method to return a new AbstractPrototypeBasedTargetSource
if they wish to create a custom TargetSource for this bean, or
null if they are
not interested it in, in which case no special target source will be created. |
void |
destroy()
Destroys the internal BeanFactory on shutdown of the TargetSourceCreator.
|
protected org.springframework.beans.factory.BeanFactory |
getBeanFactory()
Return the BeanFactory that this TargetSourceCreators runs in.
|
protected org.springframework.beans.factory.support.DefaultListableBeanFactory |
getInternalBeanFactoryForBean(String beanName)
Return the internal BeanFactory to be used for the specified bean.
|
TargetSource |
getTargetSource(Class<?> beanClass,
String beanName)
Create a special TargetSource for the given bean, if any.
|
protected boolean |
isPrototypeBased()
Return whether this TargetSourceCreator is prototype-based.
