这里解决下方案如下：

[note.xml]

Xml代码
<?xml version="1.0"?>
<note xmlns="
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

网上的例子就是在这里没设置对xmlns，这里的xmlns一定要和下面note.xsd中的targetNamespace和xmlns一致

[note.xsd]

Xml代码
<?xml version="1.0"?>
<xs:schema xmlns:xs=""
targetNamespace="/schema/note"
elementFormDefault="qualified">
<xs:element name="note">
<xs:complexType>
<xs:sequence>
<xs:element name="to" type="xs:string" />
<xs:element name="from" type="xs:string" />
<xs:element name="heading" type="xs:string" />
<xs:element name="body" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

[java]

Java代码
String configFileLocation = "/note.xml";
String xsdFileLocation = "/note.xsd";
InputStream configInputStream = this.getClass().getResourceAsStream(configFileLocation);
if (configInputStream == null) {
throw new IllegalArgumentException("can not find resource[" + configFileLocation + "]");
}

InputStream xsdInputStream = this.getClass().getResourceAsStream(xsdFileLocation);
if (xsdInputStream == null) {
throw new IllegalArgumentException("can not find resource[" + xsdFileLocation + "]");
}

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = schemaFactory.newSchema(new SAXSource(new InputSource(xsdInputStream)));
factory.setSchema(schema);

DocumentBuilder builder = factory.newDocumentBuilder();

builder.setErrorHandler(new ErrorHandler() {

@Override
public void warning(SAXParseException exception) throws SAXException {
throw new RuntimeException(exception);
}

@Override
public void fatalError(SAXParseException exception) throws SAXException {
throw new RuntimeException(exception);
}

@Override
public void error(SAXParseException exception) throws SAXException {
throw new RuntimeException(exception);
}
});

document = builder.parse(configInputStream);

System.out.println(document);
