实用地在 SOAP 1.1 和 SOAP 1.2 之间动态切换的最佳库

Question

我正在开发一个基于肥皂的网络服务应用程序。该设计有我们自己的自定义代码来生成 WSDL 和 SOAP 回复。需要支持 SOAP 1.1 和 SOAP 1.2。用于支持这种设计的最佳 SOAP 库是什么。

Answer 1

找到答案了。

JDK 1.7或更高版本确实有“javax.xml.soap”包。我们可以很容易地在两种格式之间切换。一个只需要传入SOAP协议/版本的SOAP.javax.xml.soap。 SOAPConstant 包含所有必需的常量字段。这是示例代码。

package test;

import javax.xml.soap.*;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class SOAPGenerator {

  /**
   * The test namespace.
   */
  public static final String NS = "http://www.test.com/xml/soap/";

  /**
   * Default encoding of the underlying XML in a SOAPMessage
   */
  public static final String DEFAULT_ENCODING = "UTF-8";

  public static void main(String[] args) {
    SOAPMessage soapMessage11 = null;
    SOAPMessage soapMessage12 = null;

    soapMessage11 = generateSOAP("1.1");
    soapMessage12 = generateSOAP("1.2");

    try {
      soapMessage11.writeTo(new FileOutputStream(new File("gen_soap11.xml")));
      soapMessage12.writeTo(new FileOutputStream(new File("gen_soap12.xml")));

    } catch (SOAPException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }


  }

  private static SOAPMessage generateSOAP(String version) {
    SOAPMessage soapMsg = null;
    String connectionId = "testing";
    int transactionId = 1;
    try {

      String protocol;
      if("1.1".equalsIgnoreCase(version)){
        protocol = SOAPConstants.SOAP_1_2_PROTOCOL;
      } else {
        protocol = SOAPConstants.SOAP_1_1_PROTOCOL;
      }
      MessageFactory messageFactory = MessageFactory.newInstance(protocol);
      soapMsg = messageFactory.createMessage();

      //setting the namespace declaration.
      SOAPPart sp = soapMsg.getSOAPPart();
      SOAPEnvelope se = sp.getEnvelope();
      se.addNamespaceDeclaration("test", NS);
      soapMsg.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, DEFAULT_ENCODING);
      soapMsg.setProperty(SOAPMessage.WRITE_XML_DECLARATION, "true");

      //setting the soap header.
      SOAPHeader soapHeader = soapMsg.getSOAPHeader();
      //setting the session id
      SOAPElement soapHeaderElement1 = soapHeader.addChildElement("session", "lw", NS);

      soapHeaderElement1.addTextNode(connectionId);
      //setting the transactionId
      SOAPElement soapHeaderElement2 = soapHeader.addChildElement("transactionId", "lw", NS);

      soapHeaderElement2.addTextNode(String.valueOf(transactionId));


    } catch (SOAPException e) {
      e.printStackTrace();
    }
    return soapMsg;
  }
`}
