Olá,

Primeiro, se é um projeto novo, então a recomendação é usar o conteiner CDI ao invés do conteiner JSF, assim @Named ao invés de @ManagedBean.

Segundo, você não está instanciando ou injetando o EntityManager no DAO corretamente.

Terceiro, você não está instanciando ou injetando o DAO no Controller corretamente.

Obrigado pelo retorno.

Meu pom.xml está com o CDI

Olá,

Procure pesquisar no próprio site da DevMedia: https://www.devmedia.com.br/configurando-o-cdi-em-projetos-java/37649

Tente pesquisar agora como injetar o EntityManager.

Fiz assim, mas está dando este erro


public class PaisDao implements Serializable {

final private String hql = " p FROM PaisEntity p ";

EntityManager em;

public List<PaisEntity> listarPaises() {

StringBuilder hqlSelect = new StringBuilder(hql);

final String query = "SELECT" + hqlSelect;

EntityManagerFactory factory = Persistence.createEntityManagerFactory("PaisEntity");

EntityManager manager = factory.createEntityManager();

Query querySelect = manager.createQuery(query);

@SuppressWarnings("unchecked")
List<PaisEntity> resultList = querySelect.getResultList();

return resultList;

}

Olá,

Você pode criar uma unidade de persistência (persistence unit) persistence.xml com as informação do banco de dados. E então usar o nome da unidade de persistência na sua fábrica (factory) de EntityManager.

Cassius, mas eu fiz ou não ?

Ele está dando erro na linha

Olá Guilherme Lopes,

Sua entidade PaisEntity deve esta anotada com @Entity.

@Entity
public class PaisEntity implements Serializable {
...
}


Lembrando que se você não utilizar a anotação @Table assume-se que o nome da sua tabela é o mesmo que o nome da classe. Caso não seja utilize a anotação @Table especificando o nome da tabela no banco de dados.


Espero ter ajudado. Bons estudos

Desculpe, mas a entity está assim:

Verifica se você esta utilizando hibernate-entitymanager-4.x.x.jar ou 5.x.x no seu classpath. Você esta utilizando Maven, se estiver como esta seu arquivo pom.xml?

Guilherme Lopes, Boa Tarde !

Então, o nome da sua tabela do banco postgresql é "enderecos.end_pais" ? Quem é endereços ? É um schema ?

Sua entidade vai ficar assim: 

package br.com.netsoft.desif.model.endereco;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;

/**

*/
@Entity
@Table(name = "end_pais", schema = enderecos)
public class PaisEntity implements Serializable {

private static final long serialVersionUID = 7784827196506672790L;
private Long id;
private String descricao;

@Id
@Column(name = "pai_id")
@SequenceGenerator(name = "end_pais_pai_id_seq", sequenceName = "end_pais_pai_id_seq", allocationSize = 1)
@GeneratedValue(generator = "end_pais_pai_id_seq", strategy = GenerationType.SEQUENCE)
public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;

@Column(name = "pai_descricao")
public String getDescricao() {

}

public void setDescricao(String descricao) {
