Class BeanFactoryAspectInstanceFactory

java.lang.Object
  org.springframework.aop.aspectj.annotation.BeanFactoryAspectInstanceFactory

All Implemented Interfaces:

MetadataAwareAspectInstanceFactory, AspectInstanceFactory

Direct Known Subclasses:

PrototypeAspectInstanceFactory

public class BeanFactoryAspectInstanceFactory
extends Object
implements MetadataAwareAspectInstanceFactory

AspectInstanceFactory backed by Spring IoC bean.

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

2.0

Constructor Detail

BeanFactoryAspectInstanceFactory

public BeanFactoryAspectInstanceFactory(BeanFactory beanFactory,
                                        String name)

Create a BeanFactoryAspectInstance factory. 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,
                                        String name,
                                        Class type)

Create a BeanFactoryAspectInstance factory, 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 - name of the bean

type - type that should be introspected by AspectJ.
