JAXB封送没有忽略名称空间

Question

我花了一些时间来调查是什么问题，但我不能解决它。当我在XML下面反封送和回封送时，我看到的是不同的XML。

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
 <one>test</one>
 <three>\MySG\test.jsp</three>
 <two>
    <st>
        <seeta>
            <Source>

                <problemtag xmlns="uuid:B89290D2-36FB-4EBC-A581-69B16D59EB92">
                    <p>deploy_test_page_renderingMetadata</p>
                </problemtag>
            </Source>
        </seeta>
        <Template id="tcm:1-63-32" title="Smart Compound Component Template"/>
        <Publication id="tcm:0-1-1" title="Publication"/>
    </st>
 </two>
</root>

• 在上面的xml中，只有一个标记（第一个），其余所有（包括名称空间）都是意外元素。另一个应用程序发送上述XML。

我真的不明白QName的事

如果您想要的只是保留未使用的元素并将其重新整理，我认为您应该能够做这样的事情：

@XmlRootElement(name="Root")
@XmlAccessorType(XmlAccessType.FIELD)
class Root {
    @XmlElement(name="One")
    private String one;

    @XmlAnyElement
    private List<Any> otherElements;
}

class AnyAdapter extends XmlAdapter<Element,Any> {
    @Override
    public Any unmarshal(Element element) throws Exception {
        return new Any(element);
    }

    @Override
    public Element marshal(Any any) throws Exception {
        return any.element;
    }
}

@XmlJavaTypeAdapter(AnyAdapter.class)
class Any {
    Element element;

    Any(Element element) {
        this.element = element;
    }
}
