Class BeanFactoryAspectInstanceFactory

java.lang.Object
  extended by org.springframework.aop.aspectj.annotation.BeanFactoryAspectInstanceFactory
All Implemented Interfaces:
MetadataAwareAspectInstanceFactory, AspectInstanceFactory, Ordered
Direct Known Subclasses:
PrototypeAspectInstanceFactory

public class BeanFactoryAspectInstanceFactory
extends java.lang.Object
implements MetadataAwareAspectInstanceFactory

AspectInstanceFactory implementation backed by a Spring BeanFactory.

Note that this may instantiate multiple times if using a prototype, which probably won't give the semantics you expect. Use a LazySingletonAspectInstanceFactoryDecorator to wrap this to ensure only one new aspect comes back.

2.0

Constructor Detail

BeanFactoryAspectInstanceFactory

public BeanFactoryAspectInstanceFactory(BeanFactory beanFactory,
                                        java.lang.String name)
Create a BeanFactoryAspectInstanceFactory. AspectJ will be called to introspect to create AJType metadata using the type returned for the given bean name from the BeanFactory.

Parameters:
beanFactory - BeanFactory to obtain instance(s) from
name - name of the bean

BeanFactoryAspectInstanceFactory

public BeanFactoryAspectInstanceFactory(BeanFactory beanFactory,
                                        java.lang.String name,
                                        java.lang.Class type)
Create a BeanFactoryAspectInstanceFactory, providing a type that AspectJ should introspect to create AJType metadata. Use if the BeanFactory may consider the type to be a subclass (as when using CGLIB), and the information should relate to a superclass.

Parameters:
beanFactory - BeanFactory to obtain instance(s) from
name - the name of the bean
type - the type that should be introspected by AspectJ
Method Detail

getAspectInstance

public java.lang.Object getAspectInstance()
Description copied from interface: AspectInstanceFactory
Create an instance of this factory's aspect.

Specified by:
getAspectInstance in interface AspectInstanceFactory
Returns:
the aspect instance (never null)

getAspectClassLoader

public java.lang.ClassLoader getAspectClassLoader()
Description copied from interface: AspectInstanceFactory
Expose the aspect class loader that this factory uses.

Specified by:
getAspectClassLoader in interface AspectInstanceFactory
Returns:
the aspect class loader (never null)

getAspectMetadata

public AspectMetadata getAspectMetadata()
Description copied from interface: MetadataAwareAspectInstanceFactory
Return the AspectJ AspectMetadata for this factory's aspect.

Specified by:
getAspectMetadata in interface MetadataAwareAspectInstanceFactory
Returns:
the aspect metadata

getOrder

public int getOrder()
Determine the order for this factory's target aspect, either an instance-specific order expressed through implementing the Ordered interface (only checked for singleton beans), or an order expressed through the Order annotation at the class level.

Specified by:
getOrder in interface Ordered
Returns:
the order value
