[Andromda-user] [Hibernate cartridge] [Legacy DB, many2many & composite-id]

[WalterIM]

The following code creates a composite id class suitable to Andromda 2 and 
Hibernate. It is outdated, still using xDoclet, but I hope it helps.



CompositeIdClass.vsl

#set($allIds = [])##lista com todas as chaves, pks dessa classe 
e de classes que vem de associações <<PrimaryKey>>

#foreach&#40;$id in $class.identifiers&#41;

#set&#40;$dummy = $allIds.add&#40;$id&#41; &#41;

#end

##

###foreach &#40; $associationEnd in $class.associationEnds &#41;

###if&#40;$associationEnd.association.hasExactStereotype&#40;"PrimaryKey"&#41;&#41;

###foreach&#40;$id in $associationEnd.otherEnd.type.identifiers&#41;

####talvez tenha que mudar o nome, conforme nome da ponta da assoc.

###set&#40;$dummy = $allIds.add&#40;$id&#41; &#41;

###end

###end

###end

##

#if&#40;$allIds.size&#40;&#41; > 1&#41;

package $class.packageName;



public class $&#123;class.name&#125;_id implements java.io.Serializable&#123;



&nbsp; &nbsp;public $&#123;class.name&#125;_id&#40;&#41;&#123;

&nbsp; &nbsp;&#125;



#set&#40;$args = ""&#41;

#foreach&#40;$att in $allIds&#41;

#set&#40;$args = "$&#123;args&#125;,$&#123;att.type.fullyQualifiedName&#125; 
$&#123;att.name&#125;"&#41;

#end

&nbsp; &nbsp;public 
$&#123;class.name&#125;_id&#40;$args.substring&#40;1&#41;&#41;&#123;

#foreach&#40;$att in $allIds&#41;

&nbsp; &nbsp;&nbsp; &nbsp;this.$&#123;att.name&#125; = $att.name;

#end

&nbsp; &nbsp;&#125;



#foreach&#40;$att in $allIds&#41;

&nbsp; &nbsp;

&nbsp; &nbsp;/**

##me parece que o @hibernate.column não funciona direito aqui, então optei por 
usar

## o length

###set&#40;$posIni = $theLength.indexOf&#40;'&#40;'&#41;&#41;

###if&#40;$posIni > -1&#41;

###set&#40;$posIni = $posIni + 1&#41;

###set&#40;$posFim = $theLength.indexOf&#40;'&#41;'&#41;&#41;

###set&#40;$theLength = $theLength.substring&#40;$posIni,$posFim&#41;&#41;

##&nbsp; &nbsp;*&nbsp; &nbsp;length="$theLength"
