Olá a todos!
Há pouco eu postei um problema sobre o FetchType.LAZY não estar funcionando numa relacionamento @ManyToOne quando eu chamava a classe relacionada. Bom, recomecei o projeto e tudo estava funcionando perfeitamente, até eu chegar no Interceptor. Acontece que ao adicionar o interceptador mesmo sem função nenhuma e ao registrá-lo no WebConfig, o FetchType.LAZY para de funcionar e somente colcando FetchType.EAGER é que eu consigo acessar os valores da classe relacionada.
Porém não quero gerar consultas excessivas com o FetchType.EAGER, quero que ele faça a consulta somente quando eu realmente acessar a classe selecionada.
Resumindo: Se eu remover o Interceptador ou deixar FetchType.EAGER, funciona, mas preciso do interceptador e do Lazy.
E aí, o que vocês me sugerem pra resolver isso?
Classe relacionada que preciso acessar os atributos:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(foreignKey = @ForeignKey(name="profiles_fkey"))
private Profile profile;Erro:
