如何使用 wsdl 以編程方式 (!) 驗證soap 請求/響應？

Question

假設我有一個包含請求/響應和 wsdl 文件的 xml 文件。 我如何通過 wsdl驗證請求/響應？

重要的

我知道可以使用 Spring-Ws 或 Metro 之類的容器啟用此類驗證，但我希望手動驗證沒有這樣的容器：

public static void main (String[] arg) {
     File xmlRequest = new File(arg[0]);
     File wsdlFile = new File(arg[1]);
     //....
     someValidator.validate(xmlRequest, wsdlFile);
}

如果要驗證 xml，則需要為該 xml 創建 XSD。

之后只是調用驗證方法，就像您所做的那樣。

package com.journaldev.xml;

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("EmployeeRequest.xml validates against Employee.xsd? "+validateXMLSchema("Employee.xsd", "EmployeeRequest.xml"));
      System.out.println("EmployeeResponse.xml validates against Employee.xsd? "+validateXMLSchema("Employee.xsd", "EmployeeResponse.xml"));
      System.out.println("employee.xml validates against Employee.xsd? "+validateXMLSchema("Employee.xsd", "employee.xml"));

      }

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

        try {
            SchemaFactory factory = 
                    SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
            Schema schema = factory.newSchema(new File(xsdPath));
            Validator validator = schema.newValidator();
            validator.validate(new StreamSource(new File(xmlPath)));
        } catch (IOException | SAXException e) {
            System.out.println("Exception: "+e.getMessage());
            return false;
        }
        return true;
    }
}
