JiBX解組 - 可以告訴JiBX忽略元素的順序嗎？

Question

有沒有辦法得到這個？

例如，我的XML：

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

解組時

，不用錯誤，但是當我改變順序：

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

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

我的解組（實現Struts2的ContentTypeHandler接口）：

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); 
    } 
} 

和綁定：

<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> 

所以，有可能的JiBX忽略標記順序？

Answer 1

添加ordered="false"到您的映射元素的結合：

<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>
