OneToMany?

Assuntos Gerais
#1

Pessoal, eu estou apanhando para Anotações@ vejam só :


 //*************************************************//
/*  relacionamento 1 para n
 *
 //*************************************************/
     @OneToMany(mappedBy="pessoa_id")
      private List<Mensalidade> men_id;


 //*************************************************//
/*  relacionamento n para 1
 *
 //*************************************************/
  @ManyToOne(fetch=FetchType.LAZY)
  @JoinColumn(name="men_id")
  private Pessoa pessoa_id;

Tem algum erro aqui ?

#2

Aparentemente não…Se trata de um @OneToMany multidirecional…

#3

Tem algum erro aparecendo no banco, como referência cirular por exemplo?

#4

Simplesmente não lista os detalhes ! e da um erro na hora de logar no sistema, desfiz as anotações e funciona normal:

erro e classes completa !

Boa noite

Voce tem no banco de dados, na entidade Pessoa o atributo men_id realmente?
Não parece que tem!

#7

Realmente foi bem observado ! não tenho !

#8

Então basta colocar o nome do campo correspondente a pessoa no seu banco de dados e dar continuidade.

Até a próxima

#9
