如何在 maven 项目中使用 AspectJ for Loggin？

Question

I have a maven Java EE 6 project and I have into every methods a Logger information to show in the console the beginning with parameters and the end too.

In some methods i forgot the make that so i want to use aspectJ to manage the beginning and the end to every called methods.

I use Jboss EAP6 as server and Jboss developper Studio as IDE and i found some tuturials on the net but always it talkes about spring or java aspactJ project. I installed the pluging aspectJ on my IDE and i try to add an aspect it told me that my maven project is not an aspectJ project so how can solve that?

this my maven pom.xml

                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

this my interface:

public interface IClient {
    void addClient(ClientBean clt);
}

this is the implementation:

public class ClientImpl implements IClient {
    private List<ClientBean> ListOfCustomers;

    public ClientImpl() {
        setListOfCustomers(new ArrayList<ClientBean>());
    }

    public void addClient(ClientBean clt) {
        ListOfCustomers.add(clt);
    }

    public List<ClientBean> getListOfCustomers() {
        return ListOfCustomers;
    }

    public void setListOfCustomers(List<ClientBean> listOfCustomers) {
        ListOfCustomers = listOfCustomers;
    }
}

this is a class whitch i try to make my aspectJ:

@Aspect
public class ClientAspect {
    @Pointcut("execution(* *.*(..))")
    void anyCallMethod() {}

    @Before(value = "anyCallMethod()")
    public void befor(JoinPoint joinPoint) {
        System.out.println("Before, class: "
                + joinPoint.getSignature().getDeclaringType().getSimpleName()
                + ", method: " + joinPoint.getSignature().getName());
    }

    @After(value = "anyCallMethod()")
    public void after(JoinPoint joinPoint) {
        System.out.println("After, class: "
                + joinPoint.getSignature().getDeclaringType().getSimpleName()
                + ", method: " + joinPoint.getSignature().getName());
    }
}

i have a man class to test and when i run my project it gives me nos log on the console

There are several issues with your POM:

• [major] The AspectJ Maven Plugin will not be applied if you only configure it in the pluginManagement section, but do not actually use it in the actual plugins section.
• [medium] You use an outdated version 1.4 of AspectJ Maven Plugin , which by default uses AspectJ compiler 1.6.11. I recommend you to use the current plugin version 1.7 which is based on AspectJ 1.8.2, but can be overridden to use the current version 1.8.4 in the plugin's dependencies sub-section, which I also recommend you to do because 1.8.4 contains several fixes in comparison to 1.8.2.
• [minor] Your project's dependency on AspectJ Runtime should match the version used by the AspectJ Maven Plugin .
• [minor] You do not need the project dependency on aspectjweaver which is only necessary for load-time weaving. For compile-time weaving you already use the plugin and during runtime then you only need aspectjrt .

Update:

Here is a sample config from one of my own projects (Java SE, no application server, but it should be equivalent):

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.source-target.version>1.7</java.source-target.version>
    <aspectj.version>1.8.4</aspectj.version>
