Class BeanFactoryAspectInstanceFactory

java.lang.Object

org.springframework.aop.aspectj.annotation.BeanFactoryAspectInstanceFactory

All Implemented Interfaces:

MetadataAwareAspectInstanceFactory, AspectInstanceFactory, org.springframework.core.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.

Since:

2.0

Constructor Detail

BeanFactoryAspectInstanceFactory

public BeanFactoryAspectInstanceFactory(org.springframework.beans.factory.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(org.springframework.beans.factory.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 org.springframework.core.Ordered
