Simple AOP Example

[TerpInMD]

Hello all,

I think I am close to hacking together a really simple AOP example but its not quite working. Here is my aspect class:

@Aspect
public class SystemArchitecture {

  @Pointcut("execution(public * *(..))")
  public void businessService() {
	  System.out.println("Hello World!");
	  
  }

}

In my XML file:

    <aop:aspectj-autoproxy/>
    <bean id="systemArchitecture " class="aop.SystemArchitecture"/>
     
    <bean id="service" class="service.ServiceImp" />
   
    
    <bean id="springappController" class="web.SpringappController">
        <property name="commandName"><value>command</value></property>
        <property name="commandClass"><value>command.HelloCommand</value></property>    
        <property name="formView"><value>hello.jsp</value></property>
        <property name="successView"><value>hello.jsp</value></property> 	
        <property name="service">
        	<ref bean ="service"/>
        </property>	        
    </bean>

In my controller I have a call to a method in the service.Service class called sayHello.

The small app is building and deploying fine but the pointcut method is not firing even though I thought it should for ANY pulic method because of this line:

@Pointcut("execution(public * *(..))")


What am I missing? I figure its something in the XML file.

I pretty much took the examples in the documentation and hacked it into a small web app. Any ideas?

Hi

The advice logic needs to go in another method, and that method needs to reference the pointcut and say what 'type' of advice you want (after-returning, around, before, etc.).

For example:

@Aspect
public class SystemArchitecture {

  @Pointcut("execution(public * *(..))")
  public void businessService() {}

  @Before("businessService()")
  public void sayHello() {
    System.out.println("Hello World!");
  }
}

Cheers
Rick

Thank you,

Is any configuration in the xml files needed with spring 2.0? From what I gather from the docs you can either use annotation or configure things in xml. In my simple example is anything for aop needed in the xml file?
