I have the setting below pointcut in Spring 3

 <aop:config>
        <aop:pointcut id="baseDaoPointcut"      expression="execution(* br.com.infraestrutura.domain.BaseDao+.*(..))" />
        <aop:pointcut id="baseBusinessPointcut" expression="execution(* br.com.infraestrutura.domain.BaseBusiness+.*(..))" />
       .....

I would like these two pointcut to be ignored when I annotate a class with a certain annotation, as in the example below.

@NoTransactional
public interface VendaMercadoriaBusiness extends VendaMercadoriaBaseBusiness{}

or

public interface VendaMercadoriaBusiness extends VendaMercadoriaBaseBusiness{
    @NoTransactional
    public void notificar();
}

java spring

Based on Anthony Accioly's response I came up with a solution.

Annotation:

@Retention(RetentionPolicy.RUNTIME)
public @interface NoTransactional {

}

Pointcuts declaration class:

@Aspect
public class AspectTransactionConfig {


    @Pointcut("execution(* br.com.infraestrutura.domain.BaseBusiness+.*(..))")
    public void baseBusinessPointcut() {}

    @Pointcut("@annotation(br.com.webfarma.sis.application.NoTransactional)")
    public void nonTransactionalMethod() {}

    @Pointcut("@within(br.com.webfarma.sis.application.NoTransactional)")
    public void nonTransactionalClass() {}

    @Pointcut("execution(* br.com.infraestrutura.domain.BaseDao+.*(..))")
    public void baseDaoPointcut() {}

    @Pointcut("baseBusinessPointcut() && !(nonTransactionalMethod() || nonTransactionalClass())")
    public void trasactionalBaseBusinessMethod() {}
}

Configuration XML:

  <aop:config>
        <aop:advisor advice-ref="permissaoMetodoAdvice"      pointcut="br.com.webfarma.sis.application.AspectTransactionConfig.baseDaoPointcut()"                order="1" />
        <aop:advisor advice-ref="notificacaoEntidadeAdvice"  pointcut="br.com.webfarma.sis.application.AspectTransactionConfig.baseDaoPointcut()"                order="2" />
        <aop:advisor advice-ref="transactionDaoAdvice"       pointcut="br.com.webfarma.sis.application.AspectTransactionConfig.baseDaoPointcut()"      order="3" />
        <aop:advisor advice-ref="queryFilterManagerAdvice"   pointcut="br.com.webfarma.sis.application.AspectTransactionConfig.baseDaoPointcut()"                order="4" />

        <aop:advisor advice-ref="permissaoMetodoAdvice"      pointcut="br.com.webfarma.sis.application.AspectTransactionConfig.baseBusinessPointcut()"           order="1" />
        <aop:advisor advice-ref="transactionBusinessAdvice"  pointcut="br.com.webfarma.sis.application.AspectTransactionConfig.trasactionalBaseBusinessMethod()" order="2" />
    </aop:config>

Take a look at the designators% of%,% with% and% with% in Spring documentation . See what pointcut expressions can be merged with @target , @within and @annotation to form rules like:

execution(* meuPacote.MinhaClasse+.*(..)) && !@annotation(meuPacote.NoTransactional)
execution(* meuPacote.MinhaClasse+.*(..)) && !@within(meuPacote.NoTransactional)

As expressions quickly become complex, it is worth combining named rules:

@Pointcut("execution(* br.com.infraestrutura.domain.BaseBusiness+.*(..)")
public void anyMethodInBaseBusinessOrSubtypes() {}

@Pointcut("@annotation(meuPacote.NoTransactional)")
public void nonTransactionalMethod() {}

@Pointcut("@within(meuPacote.NoTransactional)")
public void nonTransactionalClass() {}

@Pointcut("anyMethodInBaseBusinessOrSubtypes() && !nonTransactionalClass() && !nonTransactionalMethod()")
public void trasactionalBusinessMethod() {}

Unfortunately is not possible to combine named pointcuts with XML , one of the good reasons to migrate to annotations. Another thing to think about is if you really want to have an annotation for transactional methods and no types ( && ). For me it would make much more sense to mark transactional methods and types.
