xml-parsing – 使用XInclude进行解析时“尝试解析XML文件时出错

这是我的解组代码：

@Override
public T readFromReader(final Reader reader) throws Exception {
    final Unmarshaller unmarshaller = createUnmarshaller();

    final SAXParserFactory spf = SAXParserFactory.newInstance();
    spf.setXIncludeAware(true);
    spf.setNamespaceAware(true);
    //spf.setValidating(true);

    final XMLReader xr = spf.newSAXParser().getXMLReader();

    final SAXSource source = new SAXSource( xr,new InputSource(reader) );

    try {
        final T object = (T) unmarshaller.unmarshal(source);
        postReadSetup(object);
        return  object;
    } catch (final Exception e) {
        throw new RuntimeException("Cannot parse XML: Additional information is attached. Please ensure your XML is valid.",e);
    }
}

这是我的主要xml文件：

<?xml version="1.0" encoding="UTF-8" ?>
<tag1  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                xmlns:xi="http://www.w3.org/2001/XInclude"
                xsi:schemaLocation="path-to-schema/schema.xsd">

    <xi:include href="path-to-xml-files/included.xml"></xi:include>
</tag1>

并包含了：

<?xml version="1.0" encoding="UTF-8"?>
<tag2> Some text </tag2>

为了实际解组它,我创建了一个新的FileReader,其中包含我的xml文件的路径(path-to-xml-files / main.xml – 路径是正确的,因为它可以清楚地找到主文件).但是,当我运行它时,包含的文件有问题.我收到带有链接SAXParseException的UnmarshalException,并显示以下错误消息：尝试解析XML文件时出错(href =’path-to-xml-files / included.xml’).

当我手动将included.xml的内容合并到main.xml中时,它运行没有问题.

我不知道它是JAXB问题还是XInclude问题,尽管我强烈怀疑后者.

我错过了什么？
