Re: Spring and gwt (request factory)

[Alfredo Quiroga-Villamil]

In addition to declaring the base package where Spring will start to
search for your "Beans", you have to also annotate the class with
@Component.

Best regards,

Alfredo

my service class is annoted with service and my dao with repository

[Alfredo Quiroga-Villamil]

This might not directly answer your question but it'll hopefully help.
You will find all the moving pieces you need there. In my DAO, I am
injecting via @Autowired some beans (not shown in the example).

Proxy:
===============================================
@ProxyFor(value = Card.class, locator = CardLocator.class)
public interface CardProxy extends EntityProxy {
.....
===============================================

Entity:
===============================================
@Table(name = "cards")
@Entity
public class Card {

public class CardLocator extends Locator<Card, Integer>{

@Override
public Card create(Class<? extends Card> clazz) {
return new Card();
}

@Override
public Card find(Class<? extends Card> clazz, Integer id) {
return ((CardDAO) BeanContextUtil.getBean(CardDAO.class)).find(id);
}
.....
===============================================

RequestContext:
===============================================
@Service(value = CardDAO.class, locator = CardServiceLocator.class)
public interface CardRequestContext extends RequestContext {
....
===============================================

DAO:
===============================================
@Component
public class CardDAO {
....
===============================================

Service Locator:
===============================================
public class CardServiceLocator implements ServiceLocator {

@Override
public Object getInstance(Class<?> clazz) {
return BeanContextUtil.getBean(CardDAO.class);
}

}
===============================================

Bean Util:
===============================================
public class BeanContextUtil {

public BeanContextUtil() {

}

public static Object getBean(Class<?> clazz) {
HttpServletRequest request =
RequestFactoryServlet.getThreadLocalRequest();
ServletContext servletCtx = request.getSession().getServletContext();
ApplicationContext springCtx =
WebApplicationContextUtils.getWebApplicationContext(servletCtx);
return springCtx.getBean(clazz);
}

}
===============================================

[pierre leagault]

i have something similar but more generic.

public class SpringServiceLocator implements ServiceLocator {

    @Override
    public Object getInstance(Class<?> clazz) {

        HttpServletRequest request = RequestFactoryServlet.getThreadLocalRequest();
        ServletContext servletContext = request.getSession().getServletContext();
        ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(servletContext);
        return context.getBean(clazz);
    }
}

@ProxyFor(value=Account.class, locator = AccountLocator.class)
public interface AccountProxy extends EntityProxy{
....
}

public class AccountLocator extends Locator<Account, Long> {

    @Autowired
    private AccountDAO accountDAO;

    @Override
    public Account create(Class<? extends Account> clazz) {
        return new Account();

    }

    @Override
    public Account find(Class<? extends Account> clazz, Long id) {
    ...
    }
    ...
}

@Service(locator = SpringServiceLocator.class, value =AccountService.class)
public interface AccountRequest extends RequestContext {
 ...
