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)

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 or 1, with Ordered.LOWEST_PRECEDENCE indicating greatest. Same order values will result in arbitrary positions for the affected objects.

Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.

Specified by:: getOrder in interface Ordered

Returns:: the order value
See Also:: Ordered.LOWEST_PRECEDENCE
