AspectJ not working with classes without interface

Question

I'm trying to execute a method before the setter of a class noted with @Entity is called. So I have this code by now:

@Component
@Aspect
public class Observable {

 @Before("execution(* br.com.persistence.Transaction.setStatus(..))")
 public void beforeSetStatus(JoinPoint joinPoint) {
  System.out.println(joinPoint.getSignature().getName());
 }
}

My pom.xml:

          <dependency>
              <groupId>org.aspectj</groupId>
              <artifactId>aspectjrt</artifactId>
              <version>1.6.1</version>
          </dependency>
          <dependency>

             <version>${spring.version}</version>
        </dependency>
        ...
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>aspectj-maven-plugin</artifactId>

            </configuration>

                    <goals>
                        <goal>compile</goal>
                    </goals>
                </execution>
            </executions>
            <dependencies>
                <dependency>
                    <groupId>org.aspectj</groupId>
                    <artifactId>aspectjrt</artifactId>
                    <version>1.8.5</version>
                </dependency>
                <dependency>
                    <groupId>org.aspectj</groupId>
                    <artifactId>aspectjtools</artifactId>
                    <version>1.8.5</version>
                </dependency>
            </dependencies>
        </plugin>

And in spring.xml I added:

<aop:aspectj-autoproxy proxy-target-class="true"/>

If I try to pointcut an interface, it works right, but it doesn't work with classes in persistence. I don't know if it is because they don't implement an interface or because of the @Entity annotation thats troubling.

Answer 1

In order for the proxies to be created at runtime your class should either have an interface or else you should configure cglib(like in your case). http://docs.spring.io/spring-framework/docs/current/spring-framework-reference/html/aop.html
