I’m trying to perform the injection but the following battery is fired:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'siteController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private br.com.joocebox.service.DestinationFacade br.com.joocebox.controller.SiteController.destinationFacade; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'destinationFacade': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private br.com.joocebox.repositories.dao.impl.DestinationDaoImpl br.com.joocebox.service.DestinationFacade.destinationDao; nested exception is java.lang.IllegalArgumentException: Can not set br.com.joocebox.repositories.dao.impl.DestinationDaoImpl field br.com.joocebox.service.DestinationFacade.destinationDao to com.sun.proxy.$Proxy46

The injection flow is as follows:

  1. My class SiteController.java injecting DestinationFacade.java;
  2. In turn DestinationFacade.java injecting DestinationDaoImpl.java;
  3. DestinationDaoImpl.java implements DestinationDAO.java.

The strangest that the same flow is made by another stabbing in the same controler and the problem does not occur.

If necessary I can post the relevant classes.

Problem Solved, it was actually a lack of attention to my.

When I was injecting the dependency I injected my DAO implementation and not its interface. The correct flow would be this:

  1. My class SiteController.java injecting DestinationFacade.java;
  2. In turn DestinationFacade.java injecting DestinationDao.java (and not DestinationDaoImpl.java);
  3. DestinationDaoImpl.java implements DestinationDAO.java.

With the above flow works smoothly!
