Ex1:  this example program will describes working with Before advice: annotation based.

Types of advices:

1)      Before Advice   
2)      After advice
3)      Around advice
4)      After returning advice
5)      After throwing advice


Before advice:

<bean id="aspect" class="madhav.LoginAspect"></bean>
<aop:config>
<aop:aspect id="loggingAspect" ref="aspect">
<aop:before method="login"
pointcut="within(madhav.Employee)"/>
</aop:aspect>
</aop:config>


Note:  hear the advice method(login()) will call before calling the methods of(madhav.Exployee) class.

Output:

login success
madhav
101

After advice


<bean id="aspect" class="madhav.LoginAspect"></bean>
<aop:config>
<aop:aspect id="loggingAspect" ref="aspect">
<aop:after method="login"
pointcut="within(madhav.Employee)"/>
</aop:aspect>
</aop:config>




Note:  hear the advice method(login()) will call after calling the methods of(madhav.Exployee) class.

Output:

   madhav
     101
  login success

Around advice

<bean id="aspect" class="madhav.LoginAspect"></bean>
<aop:config>
<aop:aspect id="loggingAspect" ref="aspect">
<aop:around method="login"
pointcut="within(madhav.Employee)"/>
</aop:aspect>
</aop:config>


Note:  hear the advice method(login()) will call before and after  calling the methods of(madhav.Exployee) class.

Output:

login success


After returning advice

<aop:after-retruning method="login"
pointcut="within(madhav.Employee)"/>
</aop:aspect>
</aop:config>

After throwing advice
