public SimpleBeanFactoryAwareAspectInstanceFactory()
Method Detail

setAspectBeanName

public void setAspectBeanName(String aspectBeanName)
Set the name of the aspect bean. This is the bean that is returned when calling getAspectInstance().


setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)
Description copied from interface: BeanFactoryAware
Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:
setBeanFactory in interface BeanFactoryAware
Parameters:
beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.
See Also:
BeanInitializationException

getAspectInstance

public Object getAspectInstance()
Look up the aspect bean from the BeanFactory and returns it.

Specified by:
getAspectInstance in interface AspectInstanceFactory
Returns:
the aspect instance (never null)
See Also:
setAspectBeanName(java.lang.String)

getAspectClassLoader

public 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)

getOrder

public int getOrder()
Description copied from interface: Ordered
Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0, with Integer.MAX_VALUE indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Specified by:
getOrder in interface Ordered
Returns:
the order value
