      org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator

All Implemented Interfaces:: Serializable, AopInfrastructureBean, BeanClassLoaderAware, BeanFactoryAware, BeanPostProcessor, InstantiationAwareBeanPostProcessor, Ordered

Direct Known Subclasses:: AspectJAwareAdvisorAutoProxyCreator, DefaultAdvisorAutoProxyCreator

public abstract class AbstractAdvisorAutoProxyCreator
extends AbstractAutoProxyCreator
extends AbstractAutoProxyCreator

Generic auto proxy creator that builds AOP proxies for specific beans based on detected Advisors for each bean.

Subclasses must implement the abstract findCandidateAdvisors() method to return a list of Advisors applying to any object. Subclasses can also override the inherited AbstractAutoProxyCreator.shouldSkip(java.lang.Class, java.lang.String) method to exclude certain objects from auto-proxying.

Advisors or advices requiring ordering should implement the Ordered interface. This class sorts Advisors by Ordered order value. Advisors that don't implement the Ordered interface will be considered as unordered; they will appear at the end of the advisor chain in undefined order.

Constructor Detail

AbstractAdvisorAutoProxyCreator

public AbstractAdvisorAutoProxyCreator()

Method Detail

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

Description copied from interface: BeanFactoryAware

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 InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:: setBeanFactory in interface BeanFactoryAware
Overrides:: setBeanFactory in class AbstractAutoProxyCreator

Parameters:: beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.
See Also:: BeanInitializationException

initBeanFactory

protected void initBeanFactory(ConfigurableListableBeanFactory beanFactory)

getAdvicesAndAdvisorsForBean

protected Object[] getAdvicesAndAdvisorsForBean(Class beanClass,
                                                String name,
                                                TargetSource targetSource)

Description copied from class: AbstractAutoProxyCreator

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

Specified by:: getAdvicesAndAdvisorsForBean in class AbstractAutoProxyCreator

Parameters:: beanClass - the class of the bean to advise; name - the name of the bean; targetSource - the TargetSource returned by the AbstractAutoProxyCreator.getCustomTargetSource(java.lang.Class, java.lang.String) method: may be ignored. Will be null if no custom target source is in use.
Returns:: an array of additional interceptors for the particular bean; or an empty array if no additional interceptors but just the common ones; or null if no proxy at all, not even with the common interceptors. See constants DO_NOT_PROXY and PROXY_WITHOUT_ADDITIONAL_INTERCEPTORS.
See Also:: AbstractAutoProxyCreator.DO_NOT_PROXY, AbstractAutoProxyCreator.PROXY_WITHOUT_ADDITIONAL_INTERCEPTORS

findEligibleAdvisors

protected List findEligibleAdvisors(Class clazz)

Find all eligible advices for auto-proxying this class.

Parameters:: clazz - the clazz to find advisors for
Returns:: the empty list, not null, if there are no pointcuts or interceptors
See Also:: findCandidateAdvisors(), sortAdvisors(java.util.List), extendAdvisors(java.util.List)

findCandidateAdvisors

protected List findCandidateAdvisors()

Find all candidate advisors to use in auto-proxying.

Returns:: list of candidate Advisors

isEligibleAdvisorBean

protected boolean isEligibleAdvisorBean(String beanName)

Return whether the Advisor bean with the given name is eligible for proxying in the first place.

Parameters:: beanName - the name of the Advisor bean
Returns:: whether the bean is eligible

sortAdvisors

protected List sortAdvisors(List advisors)

Sort advisors based on ordering. Subclasses may choose to override this method to customize the sorting strategy.

Parameters:: advisors - the source List of Advisors
Returns:: the sorted List of Advisors
See Also:: Ordered, OrderComparator

extendAdvisors

protected void extendAdvisors(List candidateAdvisors)

Extension hook that subclasses can override to register additional Advisors, given the sorted Advisors obtained to date.

The default implementation is empty.

Typically used to add Advisors that expose contextual information required by some of the later advisors.

Parameters:: candidateAdvisors - Advisors that have already been identified as applying to a given bean
