java - JiBX解码-是否可以告诉JiBX忽略元素的顺序？

有办法解决这个问题吗？

例如，我的XML:

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

当解码时，不会出错，但是当我更改顺序时:

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

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

我的解码(实现Struts2 ContentTypeHandler接口(interface)):

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);
    }
}

并绑定(bind):

<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>

那么，JiBX是否可以忽略标签顺序？

最佳答案

在绑定(bind)中的映射元素中添加一个ordered="false":

<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>
