Meu ProductsController

package br.com.loja.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.RequestMapping;

import br.com.loja.daos.ProductDAO;
import br.com.loja.models.Product;

@Controller
@Transactional
@RequestMapping("/products")
public class ProductsController {
    
    @Autowired
    private ProductDAO products;
    
    @RequestMapping("/products/form")
    public String form(){
        return "products/form";
    }
    
    public String save(Product product){
        products.save(product);
        return "produtos/ok";
    }
}

Meu ProductDao

package br.com.loja.daos;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.springframework.stereotype.Repository;

import br.com.loja.models.Product;

@Repository
public class ProductDAO {
    
    @PersistenceContext
    private EntityManager manager;
    
    public void save(Product product){
        manager.persist(product);
    }
}

Alguém pode me ajudar como sair do erro? Agradeço pela ajuda de todos.
