動的SOAPを使用してWSDL定義を公開する方法：Spring-WSを使用したアドレスの場所

Question

WSDLを保持する環境に応じて<soap:address location="..."/>のWSDLを変更したいとします。たとえば、次のように

開発：<soap:address location="https://development.xxx.yyy.zz/abc/ws/"/>

テスト：<soap:address location="https://testing.xxx.yyy.zz/abc/ws/"/>

制作：<soap:address location="https://production.xxx.yyy.zz/abc/ws/"/>

使用このクラス：

import javax.xml.parsers.DocumentBuilder; 
import javax.xml.parsers.DocumentBuilderFactory; 
import javax.xml.transform.Source; 
import javax.xml.transform.dom.DOMSource; 
import javax.xml.transform.sax.SAXSource; 
import javax.xml.xpath.XPath; 
import javax.xml.xpath.XPathConstants; 
import javax.xml.xpath.XPathFactory; 

import org.springframework.beans.factory.InitializingBean; 
import org.springframework.core.io.Resource; 
import org.springframework.util.StringUtils; 
import org.springframework.ws.wsdl.wsdl11.SimpleWsdl11Definition; 
import org.springframework.ws.wsdl.wsdl11.Wsdl11Definition; 
import org.w3c.dom.Document; 
import org.w3c.dom.Node; 

public class DynamicUrlWsdlDefinition implements Wsdl11Definition, InitializingBean { 

    private static final String SOAP_ADDRESS_LOCATION_XPATH_EXPRESSION = "/definitions/service/port/address/@location"; 

    private static final String SOAP_ADDRESS_LOCATION_URI_PART_1 = "https://"; 

    private static final String SOAP_ADDRESS_LOCATION_URI_PART_3 = ".xxx.yyy.zz/abc/ws/"; 

    private String wsEnvironment; 

    private SimpleWsdl11Definition delegate; 

    public DynamicUrlWsdlDefinition() { 
    this.setDelegate(new SimpleWsdl11Definition()); 
    } 

    @Override 
    public Source getSource() { 
    try { 
     final DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
     final DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder(); 
     final Document document = documentBuilder.parse(((SAXSource) this.getDelegate().getSource()).getInputSource()); 

     final XPath xPath = XPathFactory.newInstance().newXPath(); 
     final Node locationAttributeNode = (Node) xPath.compile(SOAP_ADDRESS_LOCATION_XPATH_EXPRESSION) 
      .evaluate(document, XPathConstants.NODE); 
     locationAttributeNode.setTextContent(SOAP_ADDRESS_LOCATION_URI_PART_1 + this.getWsEnvironment() + SOAP_ADDRESS_LOCATION_URI_PART_3); 

     return new DOMSource(document); 
    } catch (Exception e) { 
     return this.getDelegate().getSource(); 
    } 
    } 

    private String getWsEnvironment() { 
    if (!StringUtils.hasText(wsEnvironment) || "${ws.environment}".equals(wsEnvironment)) { 
     this.setWsEnvironment("NO_DEFINED"); 
    } 
    return wsEnvironment; 
    } 

    @Override 
    public void afterPropertiesSet() throws Exception { 
    this.getDelegate().afterPropertiesSet(); 
    } 

    public void setWsdl(final Resource wsdlResource) { 
    this.getDelegate().setWsdl(wsdlResource); 
    } 

    private SimpleWsdl11Definition getDelegate() { 
    return delegate; 
    } 

    private void setDelegate(final SimpleWsdl11Definition delegate) { 
    this.delegate = delegate; 
    } 

    public void setWsEnvironment(final String wsEnvironment) { 
    this.wsEnvironment = wsEnvironment; 
    } 

} 

そして、これのSpring Bean宣言：

<bean id="pingoServiceWsdl" class="DynamicUrlWsdlDefinition"> 
    <property name="wsdl" value="classpath:/pingoService.wsdl"/> 
    <property name="wsEnvironment" value="${ws.environment}"/> 
</bean>
