It is indicating that the error is in these two classes;
package br.com.casadocodigo.loja.controller;
import javax.transaction.Transactional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import br.com.casadocodigo.loja.daos.ProductDAO;
import br.com.casadocodigo.loja.models.Product;
@Controller
@Transactional
public class ProductsController {
@Autowired
private ProductDAO productDAO;
@RequestMapping("/produtos/")
public String save(Product product){
productDAO.save(product);
return "products/ok";
}
@RequestMapping("/produtos/form")
public String form(){
return "products/form";
}
}
this class
package br.com.casadocodigo.loja.daos;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.springframework.stereotype.Repository;
import br.com.casadocodigo.loja.models.Product;
@Repository
public class ProductDAO {
@PersistenceContext
private EntityManager manager;
public void save(Product product) {
manager.persist(product);
}
}
This is my repository with the complete project;
