public class BeanFactoryAspectInstanceFactory extends Object implements MetadataAwareAspectInstanceFactory, Serializable
AspectInstanceFactory
implementation backed by a SpringBeanFactory
.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:

Constructor Detail
BeanFactoryAspectInstanceFactory
public BeanFactoryAspectInstanceFactory(BeanFactory beanFactory, 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
- the BeanFactory to obtain instance(s) fromname
- the name of the bean
BeanFactoryAspectInstanceFactory
public BeanFactoryAspectInstanceFactory(BeanFactory beanFactory, String name, @Nullable 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
- the BeanFactory to obtain instance(s) fromname
- the name of the beantype
- the type that should be introspected by AspectJ (null
indicates resolution throughBeanFactory.getType(java.lang.String)
via the bean name)
