Method Details

setBeanClassLoader

public void setBeanClassLoader(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

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

Get the order value of this object.

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

Same order values will result in arbitrary sort positions for the affected objects.

Specified by:

getOrder in interface Ordered

Returns:

the order value

• Ordered.HIGHEST_PRECEDENCE
• 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

enableAspectJWeaving

public static void enableAspectJWeaving(@Nullable
 LoadTimeWeaver weaverToUse,
 @Nullable
 ClassLoader beanClassLoader)

Enable AspectJ weaving with the given LoadTimeWeaver.

Parameters:

weaverToUse - the LoadTimeWeaver to apply to (or null for a default weaver)

beanClassLoader - the class loader to create a default weaver for (if necessary)
