execution of Spring AOP Around advice in DAO returns null in service

Question

I have written my pointcut and custom around advise, which will execute one Dao method.

Pointcut

@Pointcut("execution(* com.dao.*.get*(..))")
    public void creditPointcut(){
    }

Around Advice

@Around("creditPointcut()") 
    public void around(ProceedingJoinPoint point) throws Throwable{
        LOGGER.info("Method name: "+point.getSignature().getName()+" started");
        point.proceed();
        LOGGER.info("Method name: "+point.getSignature().getName()+" ended");

    }

Target - Dao Method

public Account getAccountDetails(int accntNo) {
        Session session = sessionFactory.getCurrentSession();
        Query query = session.createQuery("from Account where accountNo=:acctNo");
        query.setInteger("acctNo", accntNo);
        Account account = (Account)query.list().get(0);
        return account;
    }

But, this advice returns null account in my service.

Service layer method

@Override
    @Transactional(isolation=Isolation.READ_COMMITTED )
    public Account getAccountDetails(int accntNo) {
        Account account = accountDao.getAccountDetails(accntNo);
        return account;
    }

Please help me why i am getting null account in my service, after executing the around advice in Dao.

Answer 1

That's because you are not returning anything from the advice:

@Around("creditPointcut()") 
public Object around(ProceedingJoinPoint point) throws Throwable{
    LOGGER.info("Method name: "+point.getSignature().getName()+" started");
    Object ret = point.proceed();
    LOGGER.info("Method name: "+point.getSignature().getName()+" ended");
    return ret;

}
