how to configure AspectJ with JSR 286 Generic Portlet ??? any link - liferay

Question

we are developing portal application using JSR-286 portlet inside liferay tomcat.We are creating our portlet extending Generic Portlet.Now I want to apply logs on doView() and doModify() methods using AspectJ. I tried with Spring AspectJ. But Spring AspectJ works only on spring managed beans.
any luck

Answer 1

I resolved above problem.
here are some solution to get it done.
Create an Aspect
#Aspect
public class TestAspect {
TestAspect (){
System.out.println("TestAspect Initialized");
}
#Pointcut( "execution(public void doView*(javax.portlet.RenderRequest,javax.portlet.RenderResponse) throws java.io.IOException, javax.portlet.PortletException)" )
private void testDoView() {
}
#Around("testDoView()")
public void logAround(ProceedingJoinPoint joinPoint)
{
System.out.println("AROUND ADVICE START");
try{
joinPoint.proceed(joinPoint.getArgs());
}catch(PortletException portletException){
System.out.println("[AROUND ADVICE] :"+portletExceptionio.getMessgae());
}catch(IOException ioException){
System.out.println("[AROUND ADVICE] :"+ioException.getMessgae());
}
catch(Throwable throwable){
System.out.println("[AROUND ADVICE] :"+throwable.getMessage();
}
System.out.println("AROUND ADVICE EXIT");
}
}
some *.jar files are AspectJ binaries:
aspectjrt.jar - necessary in runtime for correct aspects processing;
aspectjtools.jar - contains implementation of aspectj compiler;
aspectjweaver.jar - bridge between aspectj logic and java instrumentation;
1.In command line enviroment (with Ant-build.xml)
**There are three ways to inject instructions implied by AspectJ aspects:**
<project name="aspectj-example" xmlns:aspectj="antlib:org.aspectj">
<property name="src.dir" value="src/main/java"/>
<property name="resource.dir" value="src/main/resources"/>
<property name="target.dir" value="target"/>
<property name="classes.dir" value="${target.dir}/classes"/>
<taskdef uri="antlib:org.aspectj"
resource="org/aspectj/antlib.xml"
classpath="${resource.dir}/aspectjtools.jar"/>
<path id="aspectj.libs">
<fileset dir="${resource.dir}"/>
</path>
<target name="clean">
<delete dir="${target.dir}"/>
<mkdir dir="${target.dir}"/>
<mkdir dir="${classes.dir}"/>
</target>
way 1: compile-time weaving
<target name="compile-time" depends="clean">
<aspectj:iajc source="1.5" srcdir="${src.dir}" classpathref="aspectj.libs" destDir="${classes.dir}"/>
<java classname="com.aspectj.TestTarget" fork="true">
<classpath>
<path refid="aspectj.libs"/>
<pathelement path="${classes.dir}"/>
</classpath>
</java>
</target>
way 2: post-compile weaving
<target name="post-compile" depends="clean">
<echo message="Compiling..."/>
<javac debug="true" srcdir="${src.dir}" classpathref="aspectj.libs" destdir="${classes.dir}"/>
<echo message="Weaving..."/>
<aspectj:iajc classpathref="aspectj.libs" inpath="${classes.dir}" aspectpath="${src.dir}" outJar="${classes.dir}/test.jar"/>
</target>
way 3: load-time weaving
<target name="load-time" depends="clean">
<echo message="Compiling..."/>
<javac debug="true" srcdir="${src.dir}" classpathref="aspectj.libs" destdir="${classes.dir}"/>
</target>
</project>
2.In Ecilpse (IDE environment)
select your project,than select configure->convert to AspectJ Project.
