AbstractAutoProxyCreator

Convenience constant for subclasses: Return value for "do not proxy".

Convenience constant for subclasses: Return value for "proxy without additional interceptors, just the common ones".

Logger available to subclasses

Determine the candidate constructors to use for the given bean.

Obtain a reference for early access to the specified bean, typically for the purpose of resolving a circular reference.

This callback gives post-processors a chance to expose a wrapper early - that is, before the target bean instance is fully initialized. The exposed object should be equivalent to the what postProcessBeforeInitialization(Object, String) / postProcessAfterInitialization(Object, String) would expose otherwise. Note that the object returned by this method will be used as bean reference unless the post-processor returns a different wrapper from said post-process callbacks. In other words: Those post-process callbacks may either eventually expose the same reference or alternatively return the raw bean instance from those subsequent callbacks (if the wrapper for the affected bean has been built for a call to this method already, it will be exposes as final bean reference by default).

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).

Return whether the config is frozen, and no advice changes can be made.

Create a proxy with the configured interceptors if the bean is identified as one to proxy by the subclass.

Perform operations after the bean has been instantiated, via a constructor or factory method, but before Spring property population (from explicit properties or autowiring) occurs.

This is the ideal callback for performing field injection on the given bean instance. See Spring's own AutowiredAnnotationBeanPostProcessor for a typical example.

Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

Apply this BeanPostProcessor before the target bean gets instantiated. The returned bean object may be a proxy to use instead of the target bean, effectively suppressing default instantiation of the target bean.

If a non-null object is returned by this method, the bean creation process will be short-circuited. The only further processing applied is the postProcessAfterInitialization(Object, String) callback from the configured BeanPostProcessors.

This callback will only be applied to bean definitions with a bean class. In particular, it will not be applied to beans with a "factory-method".

Post-processors may implement the extended SmartInstantiationAwareBeanPostProcessor interface in order to predict the type of the bean object that they are going to return here.

Post-process the given property values before the factory applies them to the given bean. Allows for checking whether all dependencies have been satisfied, for example based on a "Required" annotation on bean property setters.

Also allows for replacing the property values to apply, typically through creating a new MutablePropertyValues instance based on the original PropertyValues, adding or removing specific values.

Predict the type of the bean to be eventually returned from this processor's postProcessBeforeInstantiation(Class, String) callback.

Specify the AdvisorAdapterRegistry to use. Default is the global AdvisorAdapterRegistry.

Set whether the common interceptors should be applied before bean-specific ones. Default is "true"; else, bean-specific interceptors will get applied first.

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 afterPropertiesSet() method or a custom init-method.

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 afterPropertiesSet() or a custom init-method.

Set custom TargetSourceCreators to be applied in this order. If the list is empty, or they all return null, a SingletonTargetSource will be created for each bean.

Note that TargetSourceCreators will kick in even for target beans where no advices or advisors have been found. If a TargetSourceCreator returns a TargetSource for a specific bean, that bean will be proxied in any case.

TargetSourceCreators can only be invoked if this post processor is used in a BeanFactory, and its BeanFactoryAware callback is used.

Set whether or not the proxy should be frozen, preventing advice from being added to it once it is created.

Overridden from the super class to prevent the proxy configuration from being frozen before the proxy is created.

Set the common interceptors. These must be bean names in the current factory. They can be of any advice or advisor type Spring supports.

If this property isn't set, there will be zero common interceptors. This is perfectly valid, if "specific" interceptors such as matching Advisors are all we want.

Set the ordering which will apply to this class's implementation of Ordered, used when applying multiple BeanPostProcessors.

Default value is Integer.MAX_VALUE, meaning that it's non-ordered.

Set the ClassLoader to generate the proxy class in.

Default is the bean ClassLoader, i.e. the ClassLoader used by the containing BeanFactory for loading all bean classes. This can be overridden here for specific proxies.

Return whether the Advisors returned by the subclass are pre-filtered to match the bean's target class already, allowing the ClassFilter check to be skipped when building advisors chains for AOP invocations.

Default is false. Subclasses may override this if they will always return pre-filtered Advisors.

Determine the advisors for the given bean, including the specific interceptors as well as the common interceptor, all adapted to the Advisor interface.

Create an AOP proxy for the given bean.

Subclasses may choose to implement this: for example, to change the interfaces exposed.

The default implementation is empty.

Return whether the given bean is to be proxied, what additional advices (e.g. AOP Alliance interceptors) and advisors to apply.

Return the owning BeanFactory. May be null, as this object doesn't need to belong to a bean factory.

Build a cache key for the given bean class and bean name.

Create a target source for bean instances. Uses any TargetSourceCreators if set. Returns null if no custom TargetSource should be used.

This implementation uses the "customTargetSourceCreators" property. Subclasses can override this method to use a different mechanism.

Return whether the given bean class represents an infrastructure class that should never be proxied.

Default implementation considers Advisors, Advices and AbstractAutoProxyCreators as infrastructure classes.

Determine whether the given bean should be proxied with its target class rather than its interfaces. Checks the "proxyTargetClass" setting as well as the "preserveTargetClass" attribute of the corresponding bean definition.

Subclasses should override this method to return true if the given bean should not be considered for auto-proxying by this post-processor.

Sometimes we need to be able to avoid this happening if it will lead to a circular reference. This implementation returns false.

Wrap the given bean if necessary, i.e. if it is eligible for being proxied.
