Hi folks. Im trying to write a simple aspect, that will intercept classes on the same bundle, but this is not working.
Here is my Aspect:
@Aspect
@Component
public class LoginLoggerAspect {
@Pointcut("execution(* br.com.autmix.domain.spi.impl.security.LoginServiceImpl.login(..))")
public void onLogin() {}
@AfterThrowing(
pointcut = "onLogin()",
throwing = "ex"
)
public void logarTentativaFalha(AuthenticationException ex) {
if(ex.getUsuario() != null) {
// some behavior
} else {
// another behavior
}
}
}
On the bundle startup I got this error:

Thanks for any help!

Hi folks.. Doing more tests, I have some unexpected results.
First. Changing my aspect to:
@AfterThrowing(
pointcut = "execution(* br.com.autmix.domain.spi.security.*.login(..))",
throwing = "ex"
)
public void logarTentativaFalha(AuthenticationException ex) {
This works!
But if I put the complete Login Interface name, like that:
@AfterThrowing(
pointcut = "execution(* br.com.autmix.domain.spi.security.LoginService.login(..))",
throwing = "ex"
)
Ive got this error:
Caused by: java.lang.IllegalArgumentException: warning no match for this type name: br.com.autmix.domain.spi.security.LoginService [Xlint:invalidAbsoluteTypeName]
If I create a @Pointcut on the aspect, and try to use it like that:
@Pointcut("execution(* br.com.autmix.domain.spi.security.*.login(..))")
public void onLogin() {}
@AfterThrowing(
pointcut = "onLogin()",
throwing = "ex"
)
public void logarTentativaFalha(AuthenticationException ex) {
if(ex.getUsuario() != null) {
System.out.println("Necessario logar isso, tem user aqui: " + ex.getUsuario().getLogin());
} else {
System.out.println("Tentativa de login falha sem usaurio presente");
}
}
I got this error:
Caused by: java.lang.IllegalArgumentException: warning can't determine implemented interfaces of missing type br.com.autmix.domain.aspect.log.LoginLoggerAspectImpl

Declaring the pointcut explicit on the pointcut parameter of annotation works, but declaring it on a @Pointcut annotation, not.
If I use the complete name of Interface and the method to pointcut, it fails.
I appreciate any help! Thanks!!

Hi folks. Problem solved here.
Now, Im using with success AspectJ LTW and Spring AOP in some cases, with no problems, with Equinox Weaving hooks.
Im using Spring 3.1.0 with Virgo Tomcat 3.6.0.
This is what I have done:
Download this bundles:
org.eclipse.equinox.weaving.hook_1.0.200.I20120427-0800.jar
org.eclipse.equinox.weaving.aspectj_1.0.100.I20120427-0800.jar
org.eclipse.equinox.weaving.caching_1.0.100.I20120427-0800.jar
--
Virgo already contains the AspectJ Weaver. But, Ive downloaded the runtime too: (from Spring ebr)
com.springsource.org.aspectj.runtime-1.6.12.RELEASE.jar
Steps to configure:
Copy
org.eclipse.equinox.weaving.hook_1.0.200.I20120427-0800.jar
com.springsource.org.aspectj.runtime-1.6.12.RELEASE.jar
com.springsource.org.aspectj.weaver_1.6.12.RELEASE.jar
to plugins folder.
Copy
org.eclipse.equinox.weaving.aspectj_1.0.100.I20120427-0800.jar
org.eclipse.equinox.weaving.caching_1.0.100.I20120427-0800.jar
to some repository
Edit config/org.eclipse.virgo.kernel.userregion.properties
Add "file:plugins/org.eclipse.equinox.weaving.hook_1.0.200.I20120427-0800.jar" in "baseBundles". Do not set it to start, because this is a fragment bundle.
Add "com.springsource.org.aspectj.weaver;bundle-version="0"" on "bundleImports"
Add "org.eclipse.equinox.service.weaving;version="0"" on "packageImports"
Add "repository:bundle/org.eclipse.equinox.weaving.aspectj" and "repository:bundle/org.eclipse.equinox.weaving.caching" on "initialArtifacts". This is because AspectJ Weaving service must be started before your application bundles.
Edit java6-server.profile
Add "osgi.framework.extensions=org.eclipse.equinox.weaving.hook"
Now, some config in your bundles:
On your spring context:
<context:load-time-weaver aspectj-weaving="autodetect"/>
<context:spring-configured />
You must define an aop.xml file inside your META-INF folder.
This is an example:
<!DOCTYPE aspectj PUBLIC
"-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
<weaver options="-verbose -debug">
<include within="br.com.autmix.web.gui.aspect..*" />
</weaver>
<aspects>
<aspect name="br.com.autmix.web.gui.aspect.i18n.I18NAspect" />
<aspect name="br.com.autmix.web.gui.aspect.i18n.I18NVaadinAspect" />
</aspects>
</aspectj>
Note that you must include your aspect to be woven too.
You need to change your MANIFEST too.
You can have aspects and classes to be matched with this aspects in the same bundle, and you can have aspects on another bundles.
If you dont need aspects from another bundles, you only must include this line in your MANIFEST.MF:
Require-Bundle: com.springsource.org.aspectj.weaver;visibility:="reexport"
If you want weave your classes with aspects in another bundle, you need to export the packages of this aspects on the host bundle, and on the target bundle, include this on your manifest:
Require-Bundle: your.aspect.bundle
Now, you can define your aop.xml on the target bundle, and reference the aspects of the host bundle in your aspects tag.
If you want to define Spring AOP Aspects, you can proceed as documented, but, does not use "<aop:aspectj-autoproxy />". This have cause problems here.
Insted, am using:
<aop:aspectj-autoproxy>
<aop:include name="myAspectRefName"/>
</aop:aspectj-autoproxy>
I hope that this can help somebody!
Thanks!

Declaring the pointcut explicit on the pointcut parameter of annotation works, but declaring it on a @Pointcut annotation, not.
If I use the complete name of Interface and the method to pointcut, it fails.
I appreciate any help! Thanks!!
I do get the exact same exceptions, but don't really want to use AspectJ, but pure Spring AOP instead and without CGLIB proxies. Do you have any hints on how this could be achieved - maybe with a slight adaptation of your solution?
Best regards - any help is very appreciated,
Felix

Hello Felix,
if you have trouble with a fully quallified pointcut like
execution(* br.com.autmix.domain.spi.security.LoginService.login(..))
You may be able to work around this by narrowing down the pointcut using an additional pointcut designator this():
this(br.com.autmix.domain.spi.security.LoginService) and execution(* login(..))
Maybe you want to have a look at this Spring AOP example
Regards,
florian

Regarding the logging: The easiest way is to modify the serviceability.xml of Virgo itself if you do not have a log configuration in your application. Simply add something like:
<logger level="DEBUG" additivity="false" name="org.springframework">
<appender-ref ref="SIFTED_LOG_FILE" />
<appender-ref ref="LOG_FILE" />
</logger>
Then you should be able to observe whether the ClassPathBeanDefinitionScanner kicks in for example:
2013-11-27 12:44:42.641] DEBUG start-signalling-1 o.s.context.annotation.ClassPathBeanDefinitionScanner Identified candidate component class: file [/tools/virgo-tomcat-server-3.6.2.RELEASE/work/deployer/s/global/46/0/sample.homepage.jar/sample/homepage/HomepageController.class]

Hi Folks! Last week I try to use @Configurable with AspectJ LTW. The aspect works well, but I have a problem with the Spring Context used to resolve the bean.
I have a Web Bundle (WAB), and several other bundles. When I instantiate a object from another bundle, by a requisition done in the Web Application, Spring uses the context from the WAB bundle to resolve the bean dependencies, and not the context of the Bean itself. I think that Spring lookup the context using a thread context class loader, thread local references, or something like that.
I'm thinking to build my own aspect, to resolve this issue somehow (hold a context reference by each class classloader).
For now, I'm processing the bean depedencies by a static call on constructor, that asks spring to do the work.
What you guys think about it?
