Question

I want to set show_sql hibernate parameter inside java code in hibernate method, so that it can print the actual SQL query for that specific method only.

I Know using below configuration it can be done

<property name="show_sql">true</property>

But it will print all sql for all hibernate calls. I want specific for few methods
Ex.

public List<Customer> getAllCustomerListByActive(boolean isActive) {
        List<Customer> customerList = new ArrayList<Customer>();
        Criteria criteria = getSession().createCriteria(Customer.class);
        criteria.add(Restrictions.eq("isActive", isActive));
        criteria.add(Restrictions.eq("delFlag", false));
        criteria.addOrder(Order.asc("id"));
        customerList = criteria.list();        
        **//Print SQL Method Syntax will come here**
        return customerList;
    }

@Vash has given link above, which has detailed the different approaches.

But for reference to this question, and which I have used in my code is as below

try {
            CriteriaImpl c = (CriteriaImpl) criteria;
            SessionImpl s = (SessionImpl) c.getSession();
            SessionFactoryImplementor factory = (SessionFactoryImplementor) s.getSessionFactory();
            String[] implementors = factory.getImplementors(c.getEntityOrClassName());
            CriteriaLoader loader = new CriteriaLoader((OuterJoinLoadable) factory.getEntityPersister(implementors[0]),
                    factory, c, implementors[0], s.getEnabledFilters());
            Field f = OuterJoinLoader.class.getDeclaredField("sql");
            f.setAccessible(true);
            String sql = (String) f.get(loader);
        } catch (Exception e) {
        }

Its very very risky to use for Production Environment.
