public static void enableAspectJWeaving(LoadTimeWeaver weaverToUse, ClassLoader beanClassLoader) Enable AspectJ weaving with the given `LoadTimeWeaver`. Parameters weaverToUse:LoadTimeWeaver the LoadTimeWeaver to apply to (or `null` for a default weaver) beanClassLoader:ClassLoader the class loader to create a default weaver for (if necessary)

public static void enableAspectJWeaving(LoadTimeWeaver weaverToUse, ClassLoader beanClassLoader)

Enable AspectJ weaving with the given LoadTimeWeaver.

getOrder	back to summary
public int getOrder() Implements org.springframework.core.Ordered.getOrder. Doc from org.springframework.core.Ordered.getOrder. 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. Returns:int the order value Annotations @Override

public int getOrder()

Implements org.springframework.core.Ordered.getOrder.

Doc from org.springframework.core.Ordered.getOrder.

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.

Returns:int

public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException Implements org.springframework.beans.factory.config.BeanFactoryPostProcessor.postProcessBeanFactory. Doc from org.springframework.beans.factory.config.BeanFactoryPostProcessor.postProcessBeanFactory. 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. Parameters beanFactory:ConfigurableListableBeanFactory the bean factory used by the application context Annotations @Override Exceptions BeansException: in case of errors

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.

Parameters

beanFactory:ConfigurableListableBeanFactory: the bean factory used by the application context

public void setBeanClassLoader(ClassLoader classLoader) Implements org.springframework.beans.factory.BeanClassLoaderAware.setBeanClassLoader. Doc from org.springframework.beans.factory.BeanClassLoaderAware.setBeanClassLoader. 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. Parameters classLoader:ClassLoader the owning class loader Annotations @Override

public void setBeanClassLoader(ClassLoader classLoader)

Implements org.springframework.beans.factory.BeanClassLoaderAware.setBeanClassLoader.

Doc from org.springframework.beans.factory.BeanClassLoaderAware.setBeanClassLoader.

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.

Parameters

public void setLoadTimeWeaver(LoadTimeWeaver loadTimeWeaver) Implements org.springframework.context.weaving.LoadTimeWeaverAware.setLoadTimeWeaver. Doc from org.springframework.context.weaving.LoadTimeWeaverAware.setLoadTimeWeaver. 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.

public void setLoadTimeWeaver(LoadTimeWeaver loadTimeWeaver)

Implements org.springframework.context.weaving.LoadTimeWeaverAware.setLoadTimeWeaver.

Doc from org.springframework.context.weaving.LoadTimeWeaverAware.setLoadTimeWeaver.

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.

Parameters
