java - 无法解析 org.xml.sax.SAXParseException : cvc-elt. 1:找不到元素 'soapenv:Envelope' 的声明

Question

   Below is the code 


import java.io.File;
    import java.io.IOException;
 import javax.xml.XMLConstants;
  import javax.xml.transform.stream.StreamSource;
  import javax.xml.validation.Schema;
 import javax.xml.validation.SchemaFactory;
          import javax.xml.validation.Validator;

    import org.xml.sax.SAXException;


 public class XMLValidation {

public static void main(String[] args) {

    System.out.println("request.xml validates agains xsd "+validateXMLSchema("request.xsd",  "request.xml"));
  }

public static boolean validateXMLSchema(String xsdPath, String xmlPath){

    try {
        SchemaFactory factory = 
                SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Schema schema;
        try {
            schema = factory.newSchema(new File(xsdPath));
             Validator validator = schema.newValidator();
                validator.validate(new StreamSource(new File(xmlPath)));
        } catch (SAXException e) {

            // TODO Auto-generated catch block
            e.printStackTrace();
            return false;
        }

    } 
    catch (IOException e) {
        System.out.println("Exception: "+e.getMessage());

    }
    return true;
}

下面是我在验证请求 xml 和请求 xsd 时遇到的错误:

能否请您帮我在我的代码中添加什么，以便在我的 XSD 中添加 我无法在 XSD 中进行任何更改，因为它是标准的，而且 Soap:env 不存在于该请求 XSD 中，但存在于请求 XML 中，因此在验证它时说标签丢失。

你有两个选择:

1. 在 validator 可用的模式中包含 soap 模式(为了进行模式验证，您必须提供所有相关模式)
2. 从有效负载中剥离 soap 包装器元素并仅验证有效负载(假设您拥有的架构仅适用于有效负载)。您可以使用引用负载 Element 的 DOMSource 而不是 StreamSource。
