一、获取WSDL定义和endpoit地址

WSDL定义地址由开发者提供,为http://10.10.xx.xxx/webservice/Pangus.SCC.OracleEBS.WebService.dll/wsdl/IWebService

通过浏览器访问WSDL地址,可以看到endpoint地址的说明:

<service name="IWebServiceservice">

<port name="IWebServicePort" binding="tns:IWebServicebinding">

<soap:address location="http://10.10.xx.xxx/webservice/Pangus.SCC.OracleEBS.WebService.dll/soap/IWebService"/>

  </port>

</service>


二、eclipse生成Java WebService Client代理

Eclipse->New->Other->Web Service Client->输入wsdl地址->Finish。

生成的类代码为(不包含IReelIdService.java和ReelIdServiceImpl.java类):技术分享

三、调用WebService提供的方法

本例调用的是getIMSData方法,通过代理类IWebServicProxy.java调用,返回的数据为XML,需要解析

/**
    * 调用盘古WMS系统的WebService获取REELID信息
    * 返回格式是字符串,需要自己解析
    * @param reelId
    * @return String
    */
   private String getReelIdInfoFromPangusWebService(String reelId) {
       
       if (null == reelId || reelId.equals("")) {
           return "";
       }
       IWebServiceProxy wsProxy = new IWebServiceProxy();
       wsProxy.setEndpoint("http://10.10.xx.xxx/webservice/Pangus.SCC.OracleEBS.WebService.dll/soap/IWebService");
       StringHolder resultDTOXml = new StringHolder();
       StringHolder resultMsg = new StringHolder();
       try {
           Boolean success = wsProxy.getIMSData("REELID", reelId, resultDTOXml, resultMsg);
           if (!success) {
               throw new MESException("ERR-0002");
           }
       } catch (RemoteException e) {
           e.printStackTrace();
           throw new MESException("ERR-0002");
       }
       return resultDTOXml.value;
   }

四、解析XML

通过XPath解析返回的XML数据,并包装成VO。XPath有点类似于JQuery,它对XML解析,而JQuery是对DOM进行解析,XPath的具体知识可参考:http://w3school.com.cn/xpath/

/**
    * 解析盘古WMS WebService返回的REELID字符串
    * 格式:<DataSet><row><REELID>T905555273842-130706-0008</REELID><DATECODE/><QTY>5000.000</QTY><MTRL_ID>307674</MTRL_ID><STATUS>0</STATUS><CUST_REELID/></row></DataSet>
    * @param reelIdInfo REELID字符串
    * @return ReelIdVO
    */
   private ReelIdVO parseXmlToVO(String reelIdInfo) {
       System.out.println(reelIdInfo);
       LOG.debug("reelIdInfo = " + reelIdInfo);
       try {
           DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
           DocumentBuilder builder = dbf.newDocumentBuilder();
           // 增加XML定义
           //String data = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + reelIdInfo;
           StringReader sr = new StringReader(reelIdInfo);
           InputSource is = new InputSource(sr);
           Document doc = builder.parse(is);
           //Document doc = builder.parse(new File("C:/test.xml"));
           // 通过XPath查找XML节点数据
           XPathFactory factory = XPathFactory.newInstance();
           XPath xPath = factory.newXPath();
           // 根下的DataSet下的第一个row下的REELID元素文本
           XPathExpression expr = xPath.compile("/DataSet/row[1]//*");
           NodeList nodes = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
           if (null == nodes) {
               return null;
           }            
           ReelIdVO reelIdVO = new ReelIdVO();
           // 库存组织
           reelIdVO.setOrganizationId(Long.valueOf(getNodeValueByNodeName(nodes, "organizationId")));
           // REELID
           reelIdVO.setReelId(getNodeValueByNodeName(nodes, "REELID"));
           // 剩余数量
           reelIdVO.setRemainQty(Double.valueOf(getNodeValueByNodeName(nodes, "QTY")));
           // 原始数量
           reelIdVO.setQty(Double.valueOf(reelIdVO.getRemainQty()) + Double.valueOf(getNodeValueByNodeName(nodes, "usedQTY")));            
           reelIdVO.setStatus(getNodeValueByNodeName(nodes, "STATUS"));
           reelIdVO.setManufactory(getNodeValueByNodeName(nodes, "manufactory"));
           reelIdVO.setDateCode(getNodeValueByNodeName(nodes, "DATECODE"));
           reelIdVO.setLotCode(getNodeValueByNodeName(nodes, "LOTCODE"));
           reelIdVO.setInventoryItemId(Long.valueOf(getNodeValueByNodeName(nodes, "MTRL_ID")));
           reelIdVO.setCustReelId(getNodeValueByNodeName(nodes, "CUST_REELID"));
           return reelIdVO;
           
       } catch (ParserConfigurationException e) {
           e.printStackTrace();
       } catch (SAXException e) {
           e.printStackTrace();
       } catch (IOException e) {
           e.printStackTrace();
       } catch (XPathExpressionException e) {
           e.printStackTrace();
       }
       return null;
   }
