Olá o no meu GenericDao (abaixo) tem um metodo chamado getAll() que deveria listar todos os registros de uma dada tabela.
Mas está acontecendo um erro que não consigo identificar.
Como usar criteria junto com entityManger?
desde já agradeço.
código do Dao generico.
package br.com.caelum.goodbuy.dao.hibernate;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.Query;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import br.com.caelum.goodbuy.dao.GenericDao;
import br.com.caelum.goodbuy.domain.DomainObject;
@Repository
public class GenericDaoJpa<T extends DomainObject> implements GenericDao<T> {
private Class<T> type;
@Autowired(required=true)
protected EntityManager entityManager;
public GenericDaoJpa(){
super();
}
public GenericDaoJpa(Class<T> type) {
super();
this.type = type;
}
public void setEntityManager(EntityManager entityManager) {
this.entityManager = entityManager;
}
@Override
public T get(Long id) {
if (id == null) {
return null;
} else {
return entityManager.find(type, id);
}
}
@SuppressWarnings("unchecked")
@Override
public List<T> getAll() {
String sql = "select p from " + type.getName() + " p";
System.out.println(sql);
Query q = entityManager.createQuery(sql);
return q.getResultList();
}
@Override
public void save(T object) {
entityManager.persist(object);
}
@Override
public void remove(T object) {
entityManager.remove(object);
}
}
