Method Summary

static Object	enrichProxy(Class<?> beanClass, String beanName, Object[] specificInterceptors, TargetSource targetSource, String[] interceptorNames, BeanFactory beanFactory, AdvisorAdapterRegistry advisorAdapterRegistry, boolean applyCommonInterceptorsFirst) If the target of the given target source is already an advised object, then this proxy will be enriched with the known advisors.

Method Detail

enrichProxy

public static Object enrichProxy(Class<?> beanClass,
                                 String beanName,
                                 Object[] specificInterceptors,
                                 TargetSource targetSource,
                                 String[] interceptorNames,
                                 BeanFactory beanFactory,
                                 AdvisorAdapterRegistry advisorAdapterRegistry,
                                 boolean applyCommonInterceptorsFirst)

If the target of the given target source is already an advised object, then this proxy will be enriched with the known advisors. If the enrichment failed, this method will return null.

Parameters:

beanClass - the class of the bean

beanName - the name of the bean

specificInterceptors - the set of interceptors that is specific to this bean (may be empty, but not null)

targetSource - the TargetSource for the proxy, already pre-configured to access the bean

interceptorNames - Are the names of interceptors to add to proxy too.

beanFactory - Is the bean factory.

advisorAdapterRegistry - Is the advisor adapter registry.

applyCommonInterceptorsFirst - Flag if common interceptors should be applied before the specific interceptors.

Returns:

Returns the enriched proxy or null if enrichment failed for some reason.

isProxyEnrichable

public static boolean isProxyEnrichable(Class<?> beanClass,
                                        String beanName,
                                        Object[] specificInterceptors,
                                        TargetSource targetSource,
                                        BeanFactory beanFactory)

Tests if the given bean is a proxy and if it is possible to enrich it.

Parameters:

beanClass - the class of the bean

beanName - the name of the bean

specificInterceptors - the set of interceptors that is specific to this bean (may be empty, but not null)

targetSource - the TargetSource for the proxy, already pre-configured to access the bean

beanFactory - Is the factory where to get beans.

Returns:

Returns true if the given bean is a proxy and if it is possible to enrich it.

enrichProxyInternal

protected static Object enrichProxyInternal(Class beanClass,
                                            String beanName,
                                            Object[] specificInterceptors,
                                            TargetSource targetSource,
                                            String[] interceptorNames,
                                            BeanFactory beanFactory,
                                            AdvisorAdapterRegistry advisorAdapterRegistry,
                                            boolean applyCommonInterceptorsFirst,
                                            Advised proxy)

Enriches the given proxy instead of creating a new proxy.

Parameters:
