Como utilizar especialização entre classes no VRaptor?

Assuntos Gerais
#1

Fiz um mapeamento one-to-one, utilizando (Hibernate) a estratégia de herança/especialização (por ex.: Test, RangeTest, StepTest).

@Entity
@Table(name = "teste")
@Inheritance(strategy=InheritanceType.JOINED)
public class Test  {

    private Integer cdTeste;
    //Outras propriedades

    //Getters & Setters
    @Id
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="teste_seq") 
    @Column(name = "cd_teste")
    public Integer getCdTeste() {
        return cdTeste;
    }
@Entity
@Table(name = "teste_range")
@PrimaryKeyJoinColumn(name = "cd_teste_range")
public class RangeTest extends Test {

    private BigDecimal mdMinim;
    private BigDecimal mdMaxim;

A classe StepTest, tbém está mapeada como a RangeTest.

Rodando o sistema, o mapeamento “sobe” como esperado. Porém ao se executar um Insert/Submissão de um formulário,
o VRaptor não captura os valores.

No meu form os campos estão como:

<select name="rangeTest.estacao.cdEstac" >
    <option value="0">-- <fmt:message key="select"/> --</option>
    ...
</select>


<input type="text" name="rangeTest.mdMinim" />

Supondo que esses dois campos foram submitidos, no TestController o método add está assim:

@Path("/test/add")
@Post
public void add(RangeTest rangeTest) {

}

Porém a minha variável rangeTest, está com suas proriedades nulas.
Alguma idéia de como solucionar isto?

#2

vc tem todos os getters e setters pras propriedades?

habilita o log de debug do VRaptor e posta o log dessa requisição com problema aqui por favor?

#3

Sim, tenho todos os getters e setters para as propriedades.

Segue log.

    @OneToMany(mappedBy = "estacao")
    public List<Test> getTestList() {
        return testList;
    }

Alguma idéia?

#4

existe o método setCdEstac() na classe Estacao?

vc selecionou alguma estação ao salvar o test?

#5

Sim, existe esse método na classe Test e foi selecionada uma estação no formulário antes de submeter. O campo Estação é um combo como esse:

<select name="rangeTest.estacao.cdEstac" >  
     <option value="...">...</option>  
      .....
</select>

Referenciei a estação pela classe RangeTest e não pelo Test, visto que estou usando especialização.

#6

eu queria ver o log de debug do vraptor que é um pouco antes da exception…

vai estar algo do tipo:
applying rangeTest.estacao.cdEstac with [3]

#7

Esse é o log de inicialização da tela com form:

no meio do log:

cant find property for expression rangeTest.estacao.cdEstac ignoring

existe o caminho: rangeTest.getEstacao().setCdEstac() ?
os getters e setters estão no padrão javabean?

#9

A classe “RangeTest” não tem o atributo “estacao”, pois teoricamente estou herdando ele (o atributo) de “Test”. Por isso não inseri getter/setter para ele em “RangeTest” nem para os demais campos herdados.

Segue código das duas classes:

Test:


@Entity    
@Table(name = "teste")    
@Inheritance(strategy=InheritanceType.JOINED)    
public class Test  {    
   
   private Integer cdTeste;    
   private Estacao estacao;  
  
   //Outras propriedades    

   //Getters & Setters    
   @Id    
   @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="teste_seq")     
   @Column(name = "cd_teste")    
   public Integer getCdTeste() {    
      return cdTeste;    
   }    
 
   @JoinColumn(name = "cd_estac", referencedColumnName = "cd_estac")  
   @ManyToOne(optional = false, fetch = FetchType.LAZY)  
   public Station getEstacao() {  
      return estacao;  
   }  
}

RangeTest:


@Entity  
@Table(name = "teste_range")  
@PrimaryKeyJoinColumn(name = "cd_teste_range")  
public class RangeTest extends Test {    

  private BigDecimal mdMinim;  
  private BigDecimal mdMaxim;  

  //gettters & setters
}
#10

entendi o problema… vou tentar reproduzir aqui

#11

testei aqui e funcionou tranquilo…

creio que seja algum problema com os getters e setters.
se eles tiverem qqer coisa que não sejam padrão vai falhar. Por exemplo o setter não retornar void ou algum problema com maiúscula e minúscula.

tente apagá-los e gerá-los com o seu eclipse ou netbeans (ignore as anotações da jpa por enquanto)

#12

Funcionou!

Revisei os getters e setters e estão todos conforme padrão. Mas o que fiz de diferente foi acrescentar referencedColumnName=“cd_teste” na annotation @PrimaryKeyJoinColumn da classe filha. Ela ficou assim:


@Entity
@Table(name = "teste_range")
@PrimaryKeyJoinColumn(name="cd_teste_range", referencedColumnName="cd_teste")
public class RangeTest extends Test {
...
}

Valeu pela ajuda, Lucas!!!
