Ok... so here is what I did to get a typical Core Spring AOP example
working in a Cocoon 2.2 block.
1) generate the block using the Cocoon archetype.
2) add the necessary dependencies to the pom.xml
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.6.4</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.6.4</version>
</dependency>
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib-nodep</artifactId>
<version>2.2</version>
</dependency>
3) run "mvn eclipse:eclipse"
4) import the project in eclipse
5) Create an Aspect which logs if the message on the sample MyBean.java
included in the block archetype is set
------------------------------------------------------------------------
------------------------------------
package com.ciber;
import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
@Aspect
public class PropertyChangeTracker {
private Logger logger = Logger.getLogger(getClass());
@Before("execution(void com.ciber.MyBean.set*(*))")
public void trackChange(JoinPoint point) {
String name = point.getSignature().getName();
Object newValue = point.getArgs()[0];
logger.info(name + " about to change to " + newValue + "
on " + point.getTarget());
}
}
------------------------------------------------------------------------
------------------------------------
6) add an aspects.xml to META-INF/cocoon/spring
------------------------------------------------------------------------
------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:p="http://www.springframework.org/schema/p";
xmlns:aop="http://www.springframework.org/schema/aop";
xmlns:util="http://www.springframework.org/schema/util";
xmlns:pipeline="http://cocoon.apache.org/schema/pipeline";
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop

http://cocoon.apache.org/schema/pipeline
http://cocoon.apache.org/schema/pipeline/cocoon-pipeline-1.0.xsd";>
<aop:aspectj-autoproxy>
<aop:include name="propertyChangeTracker"/>
</aop:aspectj-autoproxy>
<bean id="propertyChangeTracker"
class="com.ciber.PropertyChangeTracker"/>
</beans>
------------------------------------------------------------------------
------------------------------------
7) change /COB-INF/flow/spring-bean.js and set the message so we can see
if our aspect is invoked
function demo() {
var demoBean = cocoon.getComponent("demo");
demoBean.setMessage("Changed message from flowscript ;-)");
cocoon.sendPage("screens/spring-bean",
{
"message" : demoBean.message
}
);
}
I changed logger.info() to System.out.println() to do a quick test and
the output was what I'd expect:
setMessage about to change to Changed message from flowscript ;-) on
com.ciber.myb...@16b4e30
Nice stuff....
Finally being able to play around with AOP in cocoon ;-)
Cheers,
Robby Pelssers
