Framework: Update all advices to use Springs @AspectJ support

[tjuerge]

As of Sculptor 3.0.4 only the PublishAdvice (introduced in 2010) is leveraging Springs @AspectJ support. Besides from being old-school this keeps us from using these advices with Springs Java config approach mentioned in #122.

[tjuerge]

The other Sculptor advices (ServiceContextStoreAdvice, ErrorHandlingAdvice, BasicErrorHandlingAdvice and JpaFlushEagerAdvice) can't be used with Springs @AspectJ support because their pointcut is application specific. Here the name of the applications base package is needed in the AspectJ expression.

So we have to wrap these advices into a DefaultPointcutAdvisor (together with the corresponding AspectJExpressionPointcut) to create an advisor with Spring Java config, e.g.

@Configuration
public class AopConfig {

    @Pointcut("execution(public * org.sculptor.examples.library..serviceapi.*.*(..))")
    public void service() {
    }

    @Pointcut("execution(* get*(..)) || execution(* find*(..))")
    public void readOnlyMethod() {
    }

    @Bean
    public Advice serviceContextStoreAdvice() {
        return new ServiceContextStoreAdvice();
    }

    @Bean
    public Advice errorHandlingAdvice() {
        return new ErrorHandlingAdvice();
    }

    @Bean
    public Advice jpaFlushEagerAdvice() {
        return new JpaFlushEagerAdvice();
    }

    @Bean
    public Advisor serviceContextStoreAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression("org.sculptor.examples.library.config.AopConfig.service()");
        DefaultPointcutAdvisor advisor = new DefaultPointcutAdvisor(pointcut, serviceContextStoreAdvice());
        advisor.setOrder(2);
        return advisor;
    }

    @Bean
    public Advisor errorHandlingAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression("org.sculptor.examples.library.config.AopConfig.service()");
        DefaultPointcutAdvisor advisor = new DefaultPointcutAdvisor(pointcut, errorHandlingAdvice());
        advisor.setOrder(3);
        return advisor;
    }

    @Bean
    public Advisor jpaFlushEagerAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression("org.sculptor.examples.library.config.AopConfig.service()  && !org.sculptor.examples.library.config.AopConfig.readOnlyMethod()");
        DefaultPointcutAdvisor advisor = new DefaultPointcutAdvisor(pointcut, jpaFlushEagerAdvice());
        advisor.setOrder(4);
        return advisor;
    }

}
