Boa noite a todos! Eu estou iniciando em VRaptor! Como eu estou tendo muito trabalho e retrabalho com o CRUD resolvi tentar usar o Repository ao invés de Dao. Como exemplo eu criei um projeto via vraptor scafford e copiei para minha aplicação, notei que não havia nenhum .JAR então continuo ultilizado o meus. No código na acusa nenhum problema. Mais quando acesso alguma URL que utiliza o repository!!! O erro é esse:
HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

olá amigo,

Ao que parece é que a injeção de dependencia está com problemas.
o Spring não consegue injetar a classe devido um outro objeto que nao está sendo injetado nesse seu repositorio e ao que parece é o EntityManager

Se vc debugar o código vc vai ver que vc deve ter esquecido de anotar algum objeto ou algum objeto estrá dando exception ao ser instanciado pelo spring e por isso nao se completa a injeção em cadeia

Não conheço o vRaptor mas eu entendi isso na mensagem da Exceprion

Espero ter ajudado

Lucas_Cavalcanti

vc está usando hibernate direto ou JPA?

J
jehffersson

Estou e quero continuar usando o Hibernate

L
Lucas_Cavalcanti

então vc não precisa do persistence.xml, e não deveria receber EntityManager nas classes (o erro aconteceu exatamente por isso)

J
jehffersson
Meu repositório está assim:
package br.com.lojavirtual.repositories;

import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.util.List;

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

public abstract class Repositorio<T, I extends Serializable> {
	
	protected final EntityManager gerenteDeEntidade;
	protected final Class<T> clazz;

	protected Repositorio(EntityManager entityManager) {
		this.gerenteDeEntidade = entityManager;
		
		@SuppressWarnings("unchecked")
		Class<T> clazz = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];

		this.clazz = clazz;
	}
	
	public void criar(T entity) {
		gerenteDeEntidade.persist(entity);
	}
	
	public void atualizar(T entity) {
		gerenteDeEntidade.merge(entity);
	}
	
	public void destruir(T entity) {
		gerenteDeEntidade.remove(entity);
	}
	
	public T carrega(I id) {
		return gerenteDeEntidade.find(clazz, id);
	}
	public void recarrega(T entity) {
		gerenteDeEntidade.refresh(entity);
	}
	
	public List<T> listaTudo() {
		Query query = gerenteDeEntidade.createQuery("from " + clazz.getName());

		@SuppressWarnings("unchecked")
		List<T> resultList = query.getResultList();

		return resultList;
	}
}

Alguém pode ajudar? Eu quero usar com Hibernate!

L
Lucas_Cavalcanti

só receber Session ao invés de EntityManager, e usar os respectivos métodos

J
jehffersson
Eu fiz assim:
package br.com.lojavirtual.repositories;

import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.util.List;

import org.hibernate.Session;
import org.springframework.transaction.annotation.Transactional;

public abstract class Repositorio<T, I extends Serializable> {

	protected final Class<T> clazz;
	private final Session session;

	protected Repositorio(Session session) {
		this.session = session;
		@SuppressWarnings("unchecked")
		Class<T> clazz = (Class<T>) ((ParameterizedType) getClass()
				.getGenericSuperclass()).getActualTypeArguments()[0];
		this.clazz = clazz;
	}

	@Transactional
	public void salva(T produto) {
		session.save(produto);
	}

	@Transactional
	public void atualiza(T entity) {
		session.update(entity);
	}

	@Transactional
	public void remove(T produto) {
		session.delete(produto);
	}

	@SuppressWarnings("unchecked")
	public T carrega(I id) {
		return (T) this.session.load(clazz, id);
	}

	public void recarrega(T entity) {
		session.refresh(entity);
	}

	@SuppressWarnings("unchecked")
	public List<T> listaTudo() {
		return this.session.createCriteria(clazz).list();
	}
}

Vou testar aqui!

J
jehffersson

Funcionou!
Mais agora deu uma duvida:
Tenho duas URL’s @Get("/admins/new") public Admin newAdmin() { return new Admin(); } // e @Get("/admins/{admin.login}") public Admin show(Admin admin) { return repository.localiza(admin); }
Bom o sistema está dizendo que são iguais!

java.lang.IllegalStateException: There are two rules that matches the uri '/admins/new' with method GET: [[FixedMethodStrategy: /admins/new AdminController.newAdmin() [GET]], [FixedMethodStrategy: /admins/{admin.login} AdminController.show(Admin) [GET]]] with same priority.

J
jehffersson
Lucas! Fiz isso para funcionar! Alterei aqui onde está o comentário. 
// Antes era assim:
//@Get("/admins/new")
@Get
@Path("/admins/new")
public Admin newAdmin() {
	return new Admin();
}

@Put("/admins")
public void update(Admin admin) {
	validator.validate(admin);
	validator.onErrorUsePageOf(this).edit(admin);
	repository.atualiza(admin);
	result.redirectTo(this).index();
}

@Post("/admins/{admin.login}/edit")
public Admin edit(Admin admin) {
	return repository.localiza(admin);
}

@Get("/admins/{admin.login}")
public Admin show(Admin admin) {
	return repository.localiza(admin);
}

@Delete("/admins/{admin.login}")
public void destroy(Admin admin) {
	repository.remove(repository.localiza(admin));
	result.redirectTo(this).index();  
}
L
Lucas_Cavalcanti

jefferson, faça isso:

@Get("/admins/new")  
    public Admin newAdmin() {  
        return new Admin();  
    }  
// e  
    @Get @Path(value ="/admins/{admin.login}", priority=Path.LOWEST)  
    public Admin show(Admin admin) {  
        return repository.localiza(admin);  
    }

assim o vraptor vai testar a url do /new antes, e não vai dar exception

J
jehffersson
Lucas, só funcionou assim: 
@Get @Path(value = "/admins/new", priority=Path.DEFAULT)
	public Admin newAdmin() {
		return new Admin();
	}
	
	@Put("/admins")
	public void update(Admin admin) {
		validator.validate(admin);
		validator.onErrorUsePageOf(this).edit(admin);
		repository.atualiza(admin);
		result.redirectTo(this).index();
	}
	
	@Get("/admins/{admin.login}/edit")
	public Admin edit(Admin admin) {
		return repository.busca(admin);
	}

	@Get @Path(value ="/admins/{admin.login}", priority=Path.LOWEST)
	public Admin show(Admin admin) {
		return repository.busca(admin);
	}

Vc teria um exemplo de INNER JOIN com o repositoty e Hibernate?
ex: Categoria [1] --------------------- [*] Produto [1] ------------------------- [1..5] Imagem

L
Lucas_Cavalcanti

se vc estiver com a versão 3.3.1, se eu não me engano vc não precisa colocar o priority no newAdmin…

e se eu estiver enganado, trocar @Get("/admins/new") para @Get @Path("/admins/new") já funcionaria

PS: abre outro tópico para essa dúvida do inner join

J
jehffersson

Lucas o meu ainda é a versão 3.3.0, vou atualizar hoje!

Está resolvido!
Eu já havia vasculhado tudo, quando eu praticamente tinha desistido, eu deletei todos os get’s/set’s e gerei novamente.
E pronto! Funcionou, mais agora não sei porque estava dando erro?
Mais o importânte é que deu certo! Obrigado á todos que ajudaram, eu a quem estiver lendo isso não desista nunca!

Lucas_Cavalcanti

se vc ler a exception completa:

root cause   
javax.el.PropertyNotFoundException: Property 'avaliacaoMedia' not found on type br.com.jefferson.blank.models.Comentario

ou seja, não existia o getAvaliacaoMedia na classe Comentario

J
jehffersson

OI Lucas,
O código foi gerado pelo vraptor scalfford!
Exitia sim, antes de regera-los (get e set) eu conferi, mais de alguma isso não era encontrado!
Mais está tudo certo agora!

felixcoutinho

Oe jehffersson,
me explica uma coisa, quando vc vai injetar o “Repositorio” no seu controller, vc faz isso por meio do construtor mesmo? Outra duvida, o Repositorio não é abstract? Vc tem uma instancia dele? Como vc fez? Pode mostrar?

valeu

Carlos_Tetra

Lucas no meu caso, tenho JPA, mas tenho o mesmo problema. Preciso configurar algo mais no persistent.xml.

L
Lucas_Cavalcanti

qual problema exatamente, Carlos?

C
Carlos_Tetra

Estou convertendo os meus DAOs para Generics e Repository em um projeto utilizando VRaptor e JPA. Mas tem algum problema com a injeção de dependência que não encontro.

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘usuarioController’: Unsatisfied dependency expressed through constructor argument with index 0 of type [br.com.tetrawebtrack.repository.UsuarioRepository]: : No matching bean of type [br.com.tetrawebtrack.repository.UsuarioRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

	return (List<Usuario>) repository.all();
}

}

Lucas_Cavalcanti

existe algum UsuarioRepository anotado com @Component?

C
Carlos_Tetra

Realmente o GenericBusiness não era um componente do VRaptor. Valeu obrigado, no inicio do estudo tem coisa que passa na cara e não é notada.

Alguém poderia me ajudar com esse erro:

Estou criando um exemplo simples com Spring, para entender melhor funcionamento do Spring.
