Method Detail

setBeforeExistingAdvisors

public void setBeforeExistingAdvisors(boolean beforeExistingAdvisors)

Set whether this post-processor's advisor is supposed to apply before existing advisors when encountering a pre-advised object.

Default is "false", applying the advisor after existing advisors, i.e. as close as possible to the target method. Switch this to "true" in order for this post-processor's advisor to wrap existing advisors as well.

Note: Check the concrete post-processor's javadoc whether it possibly changes this flag by default, depending on the nature of its advisor.

setBeanClassLoader

public void setBeanClassLoader(ClassLoader beanClassLoader)

Specified by:

setBeanClassLoader in interface org.springframework.beans.factory.BeanClassLoaderAware

setOrder

public void setOrder(int order)

getOrder

public int getOrder()

Specified by:

getOrder in interface org.springframework.core.Ordered

postProcessBeforeInitialization

public Object postProcessBeforeInitialization(Object bean,
                                     String beanName)

Specified by:

postProcessBeforeInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

postProcessAfterInitialization

public Object postProcessAfterInitialization(Object bean,
                                    String beanName)

Specified by:

postProcessAfterInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

isEligible

protected boolean isEligible(Object bean,
                 String beanName)

Check whether the given bean is eligible for advising with this post-processor's Advisor.

Implements caching of canApply results per bean target class. Can be overridden e.g. to specifically exclude certain beans by name.

Parameters:

bean - the bean instance

beanName - the name of the bean
