类 BeanFactoryAspectInstanceFactory

java.lang.Object

infra.aop.aspectj.annotation.BeanFactoryAspectInstanceFactory

所有已实现的接口:

MetadataAwareAspectInstanceFactory, AspectInstanceFactory, infra.core.Ordered, Serializable

直接已知子类:

PrototypeAspectInstanceFactory

public class BeanFactoryAspectInstanceFactory
extends Object
implements MetadataAwareAspectInstanceFactory, Serializable

AspectInstanceFactory implementation backed by a Framework 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.

从以下版本开始:

4.0

构造器详细资料

BeanFactoryAspectInstanceFactory

public BeanFactoryAspectInstanceFactory(infra.beans.factory.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.

参数:

beanFactory - the BeanFactory to obtain instance(s) from

name - the name of the bean

BeanFactoryAspectInstanceFactory

public BeanFactoryAspectInstanceFactory(infra.beans.factory.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.

参数:

beanFactory - the BeanFactory to obtain instance(s) from

name - the name of the bean

type - the type that should be introspected by AspectJ (null indicates resolution through BeanFactory.getType(java.lang.String) via the bean name)

方法详细资料

getAspectInstance

public Object getAspectInstance()

从接口复制的说明: AspectInstanceFactory

Create an instance of this factory's aspect.

指定者:

getAspectInstance 在接口中 AspectInstanceFactory

返回:

the aspect instance (never null)

getAspectClassLoader

@Nullable
public ClassLoader getAspectClassLoader()

从接口复制的说明: AspectInstanceFactory

Expose the aspect class loader that this factory uses.

指定者:

getAspectClassLoader 在接口中 AspectInstanceFactory

返回:

the aspect class loader (or null for the bootstrap loader)

另请参阅:

• ClassUtils.getDefaultClassLoader()

getAspectMetadata

public AspectMetadata getAspectMetadata()

从接口复制的说明: MetadataAwareAspectInstanceFactory

Return the AspectJ AspectMetadata for this factory's aspect.

指定者:

getAspectMetadata 在接口中 MetadataAwareAspectInstanceFactory

返回:

the aspect metadata

getAspectCreationMutex

@Nullable
public Object getAspectCreationMutex()

从接口复制的说明: MetadataAwareAspectInstanceFactory

Return the best possible creation mutex for this factory.

指定者:

getAspectCreationMutex 在接口中 MetadataAwareAspectInstanceFactory

返回:

the mutex object (may be null for no mutex to use)

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.

指定者:

getOrder 在接口中 infra.core.Ordered

toString

public String toString()

覆盖:

toString 在类中 Object
