Class BeanFactoryAspectInstanceFactory

java.lang.Object

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.

Since:

2.0

Constructor and Description
BeanFactoryAspectInstanceFactory(BeanFactory beanFactory, java.lang.String name) Create a BeanFactoryAspectInstanceFactory.
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.

Modifier and Type	Method and Description
java.lang.ClassLoader	getAspectClassLoader() Expose the aspect class loader that this factory uses.
java.lang.Object	getAspectInstance() Create an instance of this factory's aspect.
AspectMetadata	getAspectMetadata() Return the AspectJ AspectMetadata for this factory's aspect.
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.

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
