[RESOLVIDO] Migrando de DAO para Repository

jehffersson · Março 22, 2011, 5:07pm

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:[code]HTTP Status 500 -

Não utilizei a configuração persistence.xml porque eu não sei fazer e pq queria deixa quase como antes <persistence xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0"> − <persistence-unit name="default" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> − <properties> <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/> <property name="hibernate.connection.url" value="jdbc:hsqldb:file:tmp/devdb"/> <property name="hibernate.hbm2ddl.auto" value="update"/> <property name="hibernate.query.substitutions" value="true=1, false=0"/> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> </properties> </persistence-unit> </persistence>
Estou usando as dependencias do Spring

[code] <?xml version="1.0" encoding="UTF-8"?>

<tx:annotation-driven />

classpath:/hibernate.cfg.xml

[/code]

[code]

<?xml version='1.0' encoding='utf-8'?> com.mysql.jdbc.Driver jdbc:mysql://localhost/lojavirtual root true true org.hibernate.dialect.MySQL5InnoDBDialect

	<property name="hibernate.hbm2ddl.auto">update</property>

paulo1911 · Março 22, 2011, 5:46pm

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
Fallow

Lucas_Cavalcanti · Março 22, 2011, 5:56pm

vc está usando hibernate direto ou JPA?

jehffersson · Março 22, 2011, 7:17pm

Estou e quero continuar usando o Hibernate

Lucas_Cavalcanti · Março 22, 2011, 9:27pm

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

jehffersson · Março 23, 2011, 1:46pm

Meu repositório está assim:[code]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;
}

}[/code]

Alguém pode ajudar? Eu quero usar com Hibernate!

Lucas_Cavalcanti · Março 23, 2011, 1:59pm

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

jehffersson · Março 23, 2011, 2:52pm

Eu fiz assim:[code]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();
}

}[/code]

Vou testar aqui!

jehffersson · Março 23, 2011, 5:32pm

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.

jehffersson · Março 23, 2011, 5:49pm

Lucas!
Fiz isso para funcionar! Alterei aqui onde está o comentário.

[code]
// 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();
}[/code]

Lucas_Cavalcanti · Março 23, 2011, 6:20pm

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

jehffersson · Março 24, 2011, 7:38am

Lucas, só funcionou assim:

[code] @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);
}[/code]

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

Lucas_Cavalcanti · Março 24, 2011, 9:24am

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

jehffersson · Março 24, 2011, 12:22pm

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!

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

jehffersson · Março 25, 2011, 5:04pm

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!
