JiBX unmarshalling - è possibile dire a JiBX di ignorare l'ordine degli elementi?

Question

C'è un modo per superare questo?

Ad esempio, il mio XML:

<group> 
    <idExt>new group idext</idExt> 
    <user-id>1</user-id> 
    <parent-id>2</parent-id>   
</group> 

quando unmarshalling, va senza errori, ma quando cambio ordine:

<group> 
    <user-id>1</user-id> 
    <parent-id>2</parent-id> 
    <idExt>new group idext</idExt> 
</group> 

fallisce org.jibx.runtime.JiBXException: Expected "group" end tag, found "idExt" start tag (line 4, col 2).

mio deserializzazione (attuazione dell'interfaccia Struts2 ContentTypeHandler):

public void toObject(Reader in, Object target) { 
    try { 
     IBindingFactory bf = BindingDirectory.getFactory(target.getClass()); 
     IUnmarshallingContext umc = bf.createUnmarshallingContext(); 
     umc.setDocument(in); 
     // This un-conditional cast is the current way that JibX unmarshalls to an // already instantiated object - YUCK 
     ((IUnmarshallable)target).unmarshal(umc); 
    } catch (JiBXException e) { 
     throw new RuntimeException(e); 
    } 
} 

E vincolante:

<binding>  
    <mapping name="group" class="GroupVO" > 
     <value name="id" field="id" usage="optional"/> 
     <value name="idExt" field="idExt" usage="optional"/> 
     <value name="active" field="active" usage="optional"/> 
     <value name="created-at" field="dateCre" usage="optional"/> 
     <value name="updated-at" field="dateChg" usage="optional"/> 
     <value name="deleted-at" field="dateDel" usage="optional"/> 
     <value name="user-id" field="userId" usage="optional" /> 
     <value name="parent-id" field="parentId" usage="optional" /> 
    </mapping> 
</binding> 

Quindi, è possibile per JiBX di ignorare l'ordine dei contrassegni?

Answer 1

Aggiungi un ordered="false" al vostro elemento mappatura nel legame:

<binding>   
    <mapping name="group" class="GroupVO" ordered="false"> 
     <value name="id" field="id" usage="optional"/> 
     <value name="idExt" field="idExt" usage="optional"/> 
     <value name="active" field="active" usage="optional"/> 
     <value name="created-at" field="dateCre" usage="optional"/> 
     <value name="updated-at" field="dateChg" usage="optional"/> 
     <value name="deleted-at" field="dateDel" usage="optional"/> 
     <value name="user-id" field="userId" usage="optional" /> 
     <value name="parent-id" field="parentId" usage="optional" /> 
    </mapping> 
</binding>
