使用xmlns通过xsd进行Java验证

我需要通过XSD验证XML。如果我在没有命名空间的情况下使用xsd，那么验证是好的。但如果XSD有targetNamespace，我会得到一个错误

文本错误：cvc elt.1:找不到元素'RequestGKN'的声明。

Java代码

    Schema schema = null;
    Document document = null;

    xml = "<?xml version=\"1.0\"  encoding=\"utf-8\" ?>\n" +
            "<RequestGKN xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" xmlns=\"urn://x-artefacts-rosreestr-gov-ru/requests/gkn/3.0.9\">" +
            "<title>123</title>" +
            "</RequestGKN>";
    try {

        builderFactory.setNamespaceAware(true);
        DocumentBuilder parser = builderFactory.newDocumentBuilder();
        DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();

    Validator validator = schema.newValidator();
    validator.validate(new DOMSource(document));

Schema=null；

试一试{

setNamespaceAware（true）；
DocumentBuilder parser=builderFactory.newDocumentBuilder（）；
DocumentBuilderFactory docFactory=DocumentBuilderFactory.newInstance（）；
DocumentBuilder=docFactory.newDocumentBuilder（）；
document=builder.parse（新的InputSource（新的StringReader（xml））；

//setResourceResolver（新的ResourceResolver（））；
Source schemaFile=newstreamsource（TemplateHandler.class.getClassLoader（）.getResourceAsStream（locationXSD））；
schema=factory.newSchema（schemaFile）；
}捕获（例外e）{
e、 printStackTrace（）；
}
Validator Validator=schema.newValidator（）；
validator.validate（新的DOMSource（文档））；

在创建

DocumentBuilder

之前，请确保在

DocumentBuilderFactory

中设置了

架构。
schema
对象是线程安全的，可以毫无问题地重用

SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
