[Resolvido] Erros ao alterar anotações e mapeamento de classes

[Guevara]

Oi pessoal!
Desculpem amolar com este assunto de Classes, mas hj apresentei o meu projeto ao professor orientador e segundo ele eu deveria alterar algumas coisas aqui, pois do jeito que está causa perda de performance.
Tenho uma Classe Imovel com um atributo "avatar e tenho um List de Fotos:

@OneToMany(targetEntity=Foto.class, mappedBy = "imovel",orphanRemoval=true)	
	public List<Foto> fotos; 

public Foto getAvatar() {
		return avatar;
	}

E na classe Foto tenho:

@ManyToOne	
	private Imovel imovel;

Ele disse que usar esse list na classe Imovel causa perda de performance e que deveria ter apenas aquela anotação na classe Foto.
Outra coisa que ele sugeriu foi transformar os atributos categoria, status e modalidade em classes e fazer associação com Imovel em @OneToOne, fiz isso:

// outros atributos
@OneToOne(cascade=CascadeType.ALL)
	@JoinColumn(name="cod_status")
	private Status status;	
	@OneToOne(cascade=CascadeType.ALL)
	@JoinColumn(name="cod_modalidade")
	private Modalidade modalidade;	
	@OneToOne(cascade=CascadeType.ALL)
	@JoinColumn(name="cod_categoria")
	private Categoria categoria;
// gets, sets e metodo construtor

Adicionei ao HibernateUtil estas três novas classes e agora tá pipocando erro que não sei o motivo, não esperava que mudar estas anotações fosse causar tanto problema, segue a stacktrace:

Removi td de imovelDAO na IndexController, então não era pra dar erro nesta classe. =/
A aplicação estava rodando sem problemas, foi só fazer essas alterações que expliquei que foi td pro ralo. Até aquele atributo avatar eu tinha feito seguindo a dica do Garcia, tava chamando o avatar pela classe Imovel, e agora o professor me diz pra colocar uma coluna avatar do tipo boolean na classe Foto, justamente o que eu tinha feito antes de pedir um help aqui. O.o
O que vcs acham??? Posso confiar na dica do professor?
Abraço!!

[Guevara]

Consegui resolver os erros, a aplicação subiu e criou as tabelas:

O problema de ter removido o que existia impactou na Classe ImovelDAO, FotoDAO e Email, ou seja, eu me %$#% literalmente. Vou ter que repensar todo o código de novo pra fazer td funcionar como estava antes.
Mas a minha dúvida quanto aos questionamento referente a esta nova abordagem do professor continua de pé, aceito sugestões quanto ao assunto performance que ele mencionou.
Abraço!

[Lucas_Cavalcanti]

se vc tem um @OneToMany com mappedBy ele não é problema nenhum de performance, a menos que vc fique usando esse relacionamento no código…

ele só vai carregar a coleção na primeira vez que vc usar…

mas se vc não usar em lugar nenhum a coleção não faz sentido deixar tb…

de qqer forma o erro é:

Caused by: org.hibernate.AnnotationException: @OneToOne or @ManyToOne on br.com.imobiliaria.bean.Imovel.status references an unknown entity: br.com.imobiliaria.bean.Status  

Status não é uma entidade… se é uma enum, vc precisa anotar com @Enumerated(EnumType.STRING) e tirar o @OneToOne

pq ele sugeriu o OneToOne mesmo?

[Guevara]

Oi Lucas!!
O Status seria “disponível”, “alugado”, “vendido”, “financiado”, essas coisas, ai o admin da aplicação poderia alterar esse status editando o imóvel e poderia cadastrar outros status na classe Status. Como isto era atributo em Imovel ele disse pra transformar em classe. Agora vou ter que popular todas essas classes em combobox na JSP. Não anotei Status como @Enumerated, pq neste tópico o cara mencionou:

O único problema é que, se você possuir entidades fracas e adicionar uma nova no banco de dados, precisará adicionar no enum também , por exemplo, digamos que esses carros, no teu sistema sejam fixos. Tem uma tabela lá que é ID e NOME, ou seja, 0 é “Fusca” e 1 é “Gol”. Se você adicionar um novo valor nessa tabela, terás que atualizar o sistema e adicionar o novo enum .
http://www.guj.com.br/posts/list/78790.java

Vai que na aplicação mude mais alguma coisa, ai esse @Enumerated pode complicar. =/
Depois de refazer as anotações vou ter que alterar duas classes DAO, uma de Email e todas as JSPs, e o pior talvez tenha sido o avatar sair do imóvel e ir pra classe Foto como atributo boolean, todo o esquema de upload, exclusão de foto, seleção de avatar, vai td pro limbo. "/
Conforme ele disse, o List de Foto em banco pequeno não seria problema, mas conforme fosse crescendo, a performance seria prejudicada, apesar de não estar errado, não é recomendável, eu não sabia dessa.
Abraço!

[Lucas_Cavalcanti]

vc usa enum qdo for fixo, ou muda estaticamente (durante um deploy da aplicação somente)

vc ainda pode usar o @Embedded ou uma entidade… só cuidado pois se vc sempre precisar desses atributos, criar outras tabelas pra eles só vai deixar os seus selects mais complicados, e vai piorar a performance ao invés de melhorar. Considere o embedded

[Lagaffe]

Guevara,

No projeto aqui também não usamos enum, porem usamos o @ManyToOne e não o @OneToOne. Estou achando estranho essa opção pelo @OneToOne ou senão não entendi direito o seu projeto ou sou eu que estou fazendo errado.

[Guevara]

Oi lagaffe!
A dica do Lucas é boa, usar enum em alguns casos é bem legal, só que se precisar acrescentar ou alterar algo no código vai precisar mexer lá na classe pra adicionar mais um enum. O @Embedded é outra opção, exemplo:

public class Funcionario{
private String nome;
@Embedded
private Endereco end;
}

@Embeddable
public class Endereco{
private String nomeRua;
} 
http://www.guj.com.br/posts/list/93171.java

Só que o endereço vai pra classe Funcionario nesse exemplo, é criada uma coluna lá para persistir o endereço do Funcionario.
A anotação @OneToOne é o basicão mesmo, no meu caso, cadastro os Status dos imóveis, “disponível”, “alugado”, comprado", e na JSP populo com combobox, é só selecionar e salvar o Imovel com o status selecionado.
O problema das anotações é na hora do Hibernate buscar os dados, dependendo de como estiver ele puxa coisa desnecessária, e é ai que mora o perigo. É uma arma de fio duplo.
Abraço!

[Lagaffe]

Guevara, concordo com você. Colocar endereço como @Embedded é coerente dependendo da situação. Só me parece incoerente usar Status como @OneToOne.

[Guevara]

Foi o que eu pensei tb, meu prof orientador que sugeriu colocar como @OneToOne. Vou colocar como @Embedded e mostrar pra ele, de repente muda de idéia.
Coloquei o tópico como resolvido, já que os problemas referente aos erros foram solucionados.
