public AspectJWeavingEnabler()
Method Detail

setBeanClassLoader

public void setBeanClassLoader(java.lang.ClassLoader classLoader)
Description copied from interface: BeanClassLoaderAware
Callback that supplies the bean class loader to a bean instance.

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

Specified by:
setBeanClassLoader in interface BeanClassLoaderAware
Parameters:
classLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()

setLoadTimeWeaver

public void setLoadTimeWeaver(LoadTimeWeaver loadTimeWeaver)
Description copied from interface: LoadTimeWeaverAware
Set the LoadTimeWeaver of this object's containing ApplicationContext.

Invoked after the population of normal bean properties but before an initialization callback like InitializingBean's afterPropertiesSet() or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext(..).

NOTE: This method will only be called if there actually is a LoadTimeWeaver available in the application context. If there is none, the method will simply not get invoked, assuming that the implementing object is able to activate its weaving dependency accordingly.

Specified by:
setLoadTimeWeaver in interface LoadTimeWeaverAware
Parameters:
loadTimeWeaver - the LoadTimeWeaver instance (never null)
See Also:
InitializingBean.afterPropertiesSet(), ApplicationContextAware.setApplicationContext(org.springframework.context.ApplicationContext)

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

postProcessBeanFactory

public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
                            throws BeansException
Description copied from interface: BeanFactoryPostProcessor
Modify the application context's internal bean factory after its standard initialization. All bean definitions will have been loaded, but no beans will have been instantiated yet. This allows for overriding or adding properties even to eager-initializing beans.

Specified by:
postProcessBeanFactory in interface BeanFactoryPostProcessor
Parameters:
beanFactory - the bean factory used by the application context
Throws:
BeansException - in case of errors
