我認爲「這實際上取決於」，取決於你是如何編碼和你引用的方式，所以我要強調兩個方法：
方法一：通過直接流
您可以直接將XSD作爲輸入流傳遞到您的程序，這樣即使在XML文檔中沒有元素的命名空間時，也不需要依賴「noNamespaceSchemaLocation」屬性。
下面是一個示例程序：
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.xml.sax.InputSource;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.io.StringReader;
import javax.xml.XMLConstants;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.Source;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
import javax.xml.validation.Validator;
public class XmlSchemaValidationHelper {
public static void main(String[] argv) {
XmlSchemaValidationHelper schemaValidationHelper = new XmlSchemaValidationHelper();
schemaValidationHelper.validateAgainstSchema(new File(argv[0]), new File(argv[1]));
}
public void validateAgainstSchema(File xmlFile, File xsdFile) {
try {
System.out.println("### Starting...");
// parse an XML document into a DOM tree
DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
builderFactory.setNamespaceAware(true);
DocumentBuilder parser = builderFactory.newDocumentBuilder();
Document document = parser.parse(xmlFile);
// create a SchemaFactory capable of understanding WXS schemas
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
// load a WXS schema, represented by a Schema instance
Source schemaFile = new StreamSource(xsdFile);
Schema schema = factory.newSchema(schemaFile);
// create a Validator instance, which can be used to validate an
// instance document
Validator validator = schema.newValidator();
// validate the DOM tree
validator.validate(new DOMSource(document));
System.out.println("### Finished...");
} catch (FileNotFoundException ex) {
throw new OpenClinicaSystemException("File was not found", ex.getCause());
} catch (IOException ioe) {
throw new OpenClinicaSystemException("IO Exception", ioe.getCause());
} catch (SAXParseException spe) {
spe.printStackTrace();
throw new OpenClinicaSystemException("Line : " + spe.getLineNumber() + " - " + spe.getMessage(), spe.getCause());
} catch (SAXException e) {
throw new OpenClinicaSystemException(e.getMessage(), e.getCause());
} catch (ParserConfigurationException pce) {
throw new OpenClinicaSystemException(pce.getMessage(), pce.getCause());
}
}
public class OpenClinicaSystemException extends RuntimeException {
/**
*
*/
private static final long serialVersionUID = 1L;
private String errorCode;
private Object[] errorParams;
public OpenClinicaSystemException(String code, String message) {
this(message);
this.errorCode = code;
}
public OpenClinicaSystemException(String code, String message, Throwable cause) {
this(message, cause);
this.errorCode = code;
}
public OpenClinicaSystemException(String message, Throwable cause) {
super(message, cause);
}
public OpenClinicaSystemException(Throwable cause) {
super(cause);
}
public OpenClinicaSystemException(String message) {
super(message);
this.errorCode = message;
}
public OpenClinicaSystemException(String code, Object[] errorParams) {
this.errorCode = code;
this.errorParams = errorParams;
}
public OpenClinicaSystemException(String code, Object[] errorParams, String message) {
this(message);
this.errorCode = code;
this.errorParams = errorParams;
}
public String getErrorCode() {
return errorCode;
}
public Object[] getErrorParams() {
return errorParams;
}
public void setErrorParams(Object[] errorParams) {
this.errorParams = errorParams;
}
}
}
運行這樣的：E:\xmlValidator>java XmlSchemaValidationHelper po.xml test/po.xsd，你不需要依賴於「noNamespaceSchemaLocation」屬性，因爲你是直接傳遞XSD作爲輸入流的驗證/解析器。
這是根據XSD驗證XML的快速且骯髒的方法。
方法2：逃離XSD路徑正確
你只需要正確地逃脫你的XSD的路徑，因此使用以下代替之一：
<Module2Test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="file:///C://project//module2//src//main//java//com//test//Modules.xsd">
OR
<Module2Test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C://project//module2//src//main//java//com//test//Modules.xsd">
閱讀MSDN official article大約相同。
最後的話：使用XML命名空間和目標名稱
我會建議你應該使用XML命名空間和目標名稱與XML模式與正確的XML實例。考慮下面的示例XSD和XML。
對於任何人誰不理解XML命名空間和目標名稱的概念，我希望下面的快速分將是有益的：
- 在XSD，您需要定義「目標名稱」像這樣
targetNamespace="http://www.books.org"這沒有什麼，但是你正在爲你的實際XML實例定義命名空間。您需要在您的XML實例中使用相同的名稱空間，即http://www.books.org。
- 在XML實例，您需要：
- 從XSD製作了「目標名稱」像這樣
xmlns="http://www.books.org"
- 默認的名稱空間，然後使用「的schemaLocation」屬性來告訴XML驗證那又該在XML架構的目標命名空間，並驗證將反引用的URI的適當
xsi:schemaLocation="http://www.books.org"
示例XML：
<?xml version="1.0"?>
<BookStore xmlns="http://www.books.org" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.books.org">

你試過'XSI：noNamespaceSchemaLocation =「文件：/// C：/項目/模塊2/src目錄/主/ JAVA/COM /測試/ Modules.xsd「'？ –
是的，但我不想使用fulll文件路徑到XSD文件的相對路徑 – bontade
