How to use AfterAdvice Interface in java - spring

Question

I am new to spring.I know that AfterAdvice will cause the after method to execute whether target method completes or exits with exception, but i am not able to find out any example for it.
As AfterAdvice is a marker interface, I don't know which method i need to define in it's implementation class.
Thanks,

You do not have to implement those interfaces directly. Instead, you use either
Use #After annotation to mark the method you want to it to be called.
Use spring xml bean configuration aop:advice to declare an after advice method
However, if you choose to use ProxyFactoryBean
As you indicate that you want to use ProxyFactoryBean, you can declare the xml like this
<bean id="interceptor"
class="yourimplementation">
</bean>
<bean id="setterAdvisor"
class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
<property name="advice">
<ref bean="interceptor"/>
</property>
<property name="patterns">
<list>
<value>.*set.*</value>
</list>
</property>
</bean>
<bean id="person"
class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyInterfaces" value="com.mycompany.Person"/>
<property name="target" ref="personTarget"/>
<property name="interceptorNames">
<list>
<value>setterAdvisor</value>
</list>
</property>
</bean>
For the java implementation, there is no use to implement Advice interface. You should either implement ThrowingAdvice or AfterReturningAdvice. Refer to this for more info.
For more information, you can refer to a couple tutorial guides on Spring AOP and play around with it to get a sense.
