- All Implemented Interfaces:
- Serializable, TargetSource, BeanFactoryAware
- Direct Known Subclasses:
- AbstractPoolingTargetSource, PrototypeTargetSource, ThreadLocalTargetSource
public abstract class AbstractPrototypeBasedTargetSource
- extends AbstractBeanFactoryBasedTargetSource
Base class for dynamic TargetSources that can 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 the
getBean
method to create a new prototype instance.
Therefore, this base class extends AbstractBeanFactoryBasedTargetSource.

public AbstractPrototypeBasedTargetSource()
setBeanFactory
public void setBeanFactory(BeanFactory beanFactory)
throws BeansException
- Description copied from class:
AbstractBeanFactoryBasedTargetSource
- Set the owning BeanFactory. We need to save a reference so that we can
use the
getBean
method on every invocation.
- Specified by:
setBeanFactory
in interface BeanFactoryAware
- Overrides:
setBeanFactory
in class AbstractBeanFactoryBasedTargetSource
- Parameters:
beanFactory
- owning BeanFactory (may not be null
).
The bean can immediately call methods on the factory.
- Throws:
BeansException
- in case of initialization errors- See Also:
BeanInitializationException
newPrototypeInstance
protected Object newPrototypeInstance()
throws BeansException
- Subclasses should use this method to create a new prototype instance.
- Throws:
BeansException
