extends Object
implements BeanFactoryPostProcessor, BeanClassLoaderAware, LoadTimeWeaverAware, Ordered

Post-processor that registers AspectJ's `ClassPreProcessorAgentAdapter` with the Spring application context's default `LoadTimeWeaver`.

Method Detail

### 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; 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, 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

### 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(LoadTimeWeaver weaverToUse,
                                            ClassLoader beanClassLoader)
