如何使用动态SOAP：使用Spring-WS发布地址位置

问题描述

我希望根据保存它们的环境来更改<soap:address location="..."/>。例如：

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

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

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

wsdl

如果要使用推荐答案基本文件，并且只根据环境更改SOAP地址位置属性，请使用以下类：

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;
  }

}

并声明此Spring Bean：

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