A variável entityMananger está vindo nula

Olá pessoal!

Estou tendo um erro ao tentar consultar os pedidos na base de dados, o erro diz que o entityMananger está vindo nulo, o que poderia ser?

Controller

package br.com.alura.mvc.mudi.dao;

import java.util.List;

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

import br.com.alura.mvc.mudi.model.Pedido;

public class PedidosDAO {

    @PersistenceContext
    private EntityManager entityMananger;

    public List<Pedido> consultaTodosPedidos(){
        Query query = entityMananger.createNamedQuery("SELECT * FROM pedido", Pedido.class);
        List<Pedido> pedidos = query.getResultList();
        return pedidos;
    }
}
