Criar galeria de imagens com VRaptor 3 [Resolvido]

[Guevara]

Oi pessoal!!
A saga continua, tô tentando fazer uma galeria de imagens mas tá complicado.

Tenho uma classe Imagens com atributo urlImagem:

	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private Long id;
	@Column(name="url_imagem")
	private String urlImagem;
	@ManyToOne
	@JoinColumn(name="id_imovel")
	private Imovel imovel;

Na classe Imovel está:

@OneToMany(mappedBy="Imovel")
	public List<Imagem> getImagem() {
		return getImagem() ;
	}	

Na classe componente Imagens está:

public void salva(UploadedFile imagem, Imovel imovel) {	
		String uuid = UUID.randomUUID().toString();
		File destino = new File(pastaImagens, imovel.getIdImovel() + ".imagem"+uuid);
		try {
			IOUtils.copyLarge(imagem.getFile(), new FileOutputStream(destino));
			//String urlImagem = imagem.getFileName();
			//String urlImagem = destino.getAbsoluteFile();
			//img.setUrlImagem(urlImagem);
			//imagemDAO.adiciona(urlImagem);
		} catch (IOException e) {
			throw new RuntimeException("Erro ao copiar imagem", e);
		}
	}

Como podem ver, preciso pegar o “destino” e persistir em Imagem, mas não sei como fazer isso. Pelo menos já consigo salvar imagens como nomes diferentes usando a classe uuid, criei um método pra ver se a imagem já existe(não sei se vai funcionar):

public boolean existeImagem(Imagem imagem) {
		Imagem encontrada = (Imagem) session.createCriteria(Imagem.class)
	    .add(Restrictions.eq("urlImagem", imagem.getUrlImagem()))
	    .uniqueResult();
		return encontrada != null;
	}

Têm como salvar e obter as imagens do banco sem precisar daquele @Path(/imovel/{imovel.idImovel}/imagem)? Queria apenas usar o banco pra isso.
Tô precisando da ajuda de vcs pra resolver essa salada. =/
Abraço!!

Você quer gravar a imagem no banco de dados, ou quer salvar o caminho da imagem no banco e acessá-la pelo filesystem?

[Guevara]

Oi Garcia!!!
Quero salvar o caminho no banco, ai depois quero chamar esse caminho para popular uma tabela por exemplo. Criar uma galeria mesmo com varias fotos referentes àquele imóvel.

[garcia-jj]

Porque você usou na entidade imóvel uma lista de imagens, porém com o atributo no singular? O relacionamento de imóvel > imagem é one-to-many ou one-to-one? Além disso sua entidade Imagem possui apenas o caminho da imagem ou tem mais algum atributo?

[Guevara]

Coloquei getImagem pq a classe é Imagem, só pra eu não me perder.
A idéia é um imóvel ter várias imagens, mas uma imagem pertencer a apenas um imóvel. não está certo?? =/

Se você tem uma lista de imagens deveria ser getImagens() e não getImagem().

Se você tem apenas o caminho da imagem você nem mesmo precisa da entidade imagem, pois no hibernate e no JPA2 você pode ter uma lista de strings.

Sua classe Imóvel

[code]public class Imovel {
[…]

@OneToMany
public List<Imagem> imagens;

public List<Imagem> getImagens() {
    return imagens;
}

public void setImagens(List<Imagem> imagens) {
    this.imagens = imagens;
}

}[/code]

No seu controller

[code] public void salva(UploadedFile imagem, Imovel imovel) {
String uuid = UUID.randomUUID().toString();
File destino = new File(pastaImagens, imovel.getIdImovel() + “.imagem” + uuid);

    try {
        IOUtils.copyLarge(imagem.getFile(), new FileOutputStream(destino));
        
        Imagem imagem = new Imagem();
        imagem.setUrl(destino.getName());
        
        // salva aqui a imagem no banco
    } catch (IOException e) {
        throw new RuntimeException("Erro ao copiar imagem", e);
    }
}

}[/code]

Sua entidade imagem me parece correta para o propósito que você quer. Perguntei se ela contém apenas o caminho da imagem porque se ela tiver apenas essa propriedade você pode usar o @ElementCollection.

Olha ai Garcia, tá dando erro para criar o relacionamento:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'br.com.caelum.vraptor.util.jpa.EntityManagerCreator': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'entityManagerCreator': Unsatisfied dependency expressed through constructor argument with index 0 of type [javax.persistence.EntityManagerFactory]: : Error creating bean with name 'br.com.caelum.vraptor.util.jpa.EntityManagerFactoryCreator': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryCreator': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.OneToOne.orphanRemoval()Z; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'br.com.caelum.vraptor.util.jpa.EntityManagerFactoryCreator': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryCreator': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.OneToOne.orphanRemoval()Z

Tô fazendo assim, classe Imovel:

@OneToMany(mappedBy="imovel")
	public List<Imagem> imagens;

	public List<Imagem> getImagens() {
	      return imagens;
	}

	public void setImagens(List<Imagem> imagens) {
	      this.imagens = imagens;
	}

Classe Imagem:

@ManyToOne
	@JoinColumn(name="id_imovel")
	private Imovel imovel;
	
	
	public Imovel getImovel() {
		return imovel;
	}
	public void setImovel(Imovel imovel) {
		this.imovel = imovel;
	}

Tentei de outras formas seguindo exemplo de uma revista de Java que tenho aqui e não tá dando certo. =/

[garcia-jj]

Que coisa estranha. Você está usando qual appserver e qual versão do Hibernate?

Abraços

Que coisa estranha. Você está usando qual appserver e qual versão do Hibernate?

Abraços

[Guevara]

Tô usando o Hibernate 3.5 final e Tomcat 6.0.26, a última versão.
Nem seguindo esta dica resolveu:
http://code.google.com/p/exemplos/wiki/jpaCinco
Tá osso! =/

[Guevara]

Achei isto aqui: http://javablog.co.uk/2009/12/27/onetomany-fixes-in-jpa-2/

Parece que mudaram a forma de criar esse tipo de coleções, e para usar as novidades teria que alterar o persistent.xml.
O parâmetro orphanRemoval = true não deu certo tb.

[Guevara]

É, parece que para mapear agora é:

@ElementCollection
	public List<Imagem> imagens;
	
	public List<Imagem> getImagens() {
	      return imagens;
	}

	public void setImagens(List<Imagem> imagens) {
	      this.imagens = imagens;
	}

E na classe Imagem:

@ManyToOne
	@JoinColumn(nullable = false)
	private Imovel imovel;
	
	public Imovel getImovel() {
		return imovel;
	}
	public void setImovel(Imovel imovel) {
		this.imovel = imovel;
	}

A saida do erro mudou:

Acontece que na IndexContoller estou mandando uma lista para a pagina index.jsp:

result.include("imovel", imovelDao.lista());

E na ImovelDAO está listando assim:

@SuppressWarnings("unchecked")
	public List<Imovel> lista() {
		return session.createCriteria(Imovel.class).list();

Preciso alterar a forma de listar imóveis para que resolva esse erro?
Abraço!!!

Dei uma pesquisa aqui e achei uns links sobre JPA 2:
http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html/configuration.html

JPA 2.0 : standard properties in persistence.xml

http://www.edsongoncalves.com.br/2010/02/03/jpa-2-0-na-pratica-parte-2/

Fui alterando o persistence.xml até ficar assim:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"
			 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
			 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
			 http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="Account" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>  
        <properties>        	
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
            <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost/imobiliaria" />
            <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
            <property name="javax.persistence.jdbc.password" value="senha" />
            <property name="javax.persistence.jdbc.user" value="postgres" />
            <property name="hibernate.hbm2ddl.auto" value="update" />

            <property name="hibernate.format_sql" value="true"/>           
        </properties>
</persistence-unit>
</persistence>

O erro que dá é que o persistence unit está como “default”, sendo que no meu está persistence-unit name=“Account”. Se colocar default dá o mesmo erro:

De onde ele está tirando esse default?
Abraço!!

[garcia-jj]

Tentei de outras formas seguindo exemplo de uma revista de Java que tenho aqui e não tá dando certo. =/

Há alguma mensagem de erro? O que está acontecendo?:

Tô usando o Hibernate 3.5 final e Tomcat 6.0.26, a última versão.

Dê uma olhada se as suas libs estão corretas. Provavelmente você está usando Hibernate 3.5 com jars do JPA1 ao invés do JPA2.

@ElementCollection public List<Imagem> imagens;

Não use assim, está errado. @ElementCollection é quando você tem um List de Strings ou List e Enums. Não para quando você tem um List de entidade, que nesse caso deverá ser um @OneToMany

De onde ele está tirando esse default?

Para o vraptor trabalhar automagicamente com o entity-manager o nome dela deverá ser default. De uma olhada lá no final da página: http://vraptor.caelum.com.br/documentacao/componentes-utilitarios-opcionais/

[Guevara]

Salve !!!
O jar hibernate-jpa-2.0-api-1.0.0.Final.jar está na minha lib, no meu persistence.xml está como “default” e o erro continua sendo:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'entityManagerCreator': Unsatisfied dependency expressed through constructor argument with index 0 of type [javax.persistence.EntityManagerFactory]: : Error creating bean with name 'br.com.caelum.vraptor.util.jpa.EntityManagerFactoryCreator': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryCreator': Invocation of init method failed; nested exception is javax.persistence.PersistenceException: No Persistence provider for EntityManager named default; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'br.com.caelum.vraptor.util.jpa.EntityManagerFactoryCreator': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryCreator': Invocation of init method failed; nested exception is javax.persistence.PersistenceException: No Persistence provider for EntityManager named default

O provider que está no meu persistence.xml (org.eclipse.persistence.jpa.PersistenceProvider) é o correto para usar com persistent-unit default?
Abraço!!!

[garcia-jj]

Sabe que e nunca trabalhei com JPA que não fosse em ambiente não gerenciado. A unica vez que usei JPA não gerenciado com Vraptor em um projeto de testes apanhei um monte, e se não me engano meu erro era de colocar o persistence.xml dentro do /src/META-INF.

[Guevara]

O meu está em /src/META-INF. O.o
Como vc conseguiu resolver??

[Guevara]

Preciso me benzer!
https://forum.hibernate.org/viewtopic.php?f=1&t=1003996
Só falta ser bug e eu não poder usar uma anotação @OneToMany.
Meu web.xml está padrão:

<context-param>  
    <param-name>br.com.caelum.vraptor.provider</param-name>  
    <param-value>br.com.caelum.vraptor.util.jpa.JPACustomProvider</param-value>  
    </context-param>

O persistence.xml deixei como estava antes:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
    <persistence-unit name="default">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>  
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
            <property name="hibernate.connection.url" value="jdbc:postgresql://localhost/imobiliaria" />
            <property name="hibernate.connection.driver_class" value="org.postgresql.Driver" />
            <property name="hibernate.connection.password" value="senha" />
            <property name="hibernate.connection.username" value="postgres" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="true"/>
            <property name="hibernate.format_sql" value="true"/>           
        </properties>
</persistence-unit>
</persistence>

E o erro é:

o: Error creating bean with name 'entityManagerFactoryCreator': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z

Será que é algum bug com o ComponentFactories do VRaptor??? =/

[garcia-jj]

Será que é algum bug com o ComponentFactories do VRaptor??? =/

Isso não sei te dizer porque não uso esses componentes do vraptor. O Lucas que pode nos dizer melhor se o Vraptor suporta JPA2, já que você usa Hibernate 3.5.

Aliás você está usando Hibernate 3.5.final? Você tem mais algum jar do JPA no classpath? Você está usando qual appserver?

[garcia-jj]

Ei, você está usando o Eclipselink como implementação de JPA. Note essa linha no seu persistence.xml:

para usar Hibernate é:

Vou te passar um exemplo do meu persistence.xml. Com pequenas alterações funciona para você. Como você não está em um ambiente gerenciado altere o transaction-type para RESOURCE_LOCAL, e remova o datasource. Adicione suas propriedades de conexão javax.persistence.jdbc* e remova minhas propriedades de cache. Após creio que tudo se resolve.

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


org.hibernate.ejb.HibernatePersistence
jdbc/cobDS

	<properties>

Obrigado pela dica Garcia, eu já estava usando o Provider do Hibernate, reparei que esse precisaria registrar seguindo a dica do site do VRaptor, mas isso eu não saberia fazer, tô achando que é algo no VRaptor que precisa ser modificado pro entityManager funcionar.

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'br.com.caelum.vraptor.util.jpa.EntityManagerFactoryCreator': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryCreator': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z

O meu persistence.xml está assim:

            <property name="hibernate.format_sql" value="true"/>           
        </properties>
</persistence-unit>
</persistence>

A anotação está correta:

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "imovel")	
	public List<Imagem> imagens;

public List<Imagem> getImagens() {
	      return imagens;
	}

	public void setImagens(List<Imagem> imagens) {
	      this.imagens = imagens;
	}

@ManyToOne
	@JoinColumn
	private Imovel imovel;

Só falta remover o Hibernate 3.5 e voltar pro velho. =/
