Spring AOP Aspect used in JdbcOperations not invoked

Question

I want to do something like this<\/strong> : http:\/\/www.gotoquiz.com\/web-coding\/programming\/java-programming\/log-sql-statements-with-parameter-values-filled-in-spring-jdbc\/<\/a>

public abstract class GenericDaoImpl {
    @Autowired
    protected JdbcTemplate jdbcTemplate;
}


@Repository
public class UserDAOImpl extends GenericDaoImpl implements UserDAO{

}

Answer 1

Your aop expression is defined as a pointcut to a JdbcOperation.* which is an interface, and interface calls are not advised.

AspectJ can intercept pointcuts in the spring framework for spring-managed-beans. If the bean is not spring managed you'll need to manually register it using ProxyFactoryBean/ProxyFactory for advisal. In your case you already have a bean implementing the JdbcOperations interface registered in your spring application-context.

As per your problem changing the pointcut to use any implementation of the JdbcOperations interface ( the jdbcTemplate bean definition ) should solve your problem.

For example

@Before("execution(* org.springframework.jdbc.core.JdbcOperations+.*(..))")

Answer 2

you lost 1 .* in the expression,it should be

// this works fine 
@Before("execution(* org.springframework.jdbc.core..*JdbcOperations.*(String, ..))") 

But you wrote like

// this's not good 
@Before("execution(* org.springframework.jdbc.core.JdbcOperations.*(..))")
