解析Java中的SOAP響應

Question

我無法成功解析Java中的SOAP響應（使用Bonita Open Solution BPM）。 我有以下SOAP響應（搜索在IBM內容管理的文檔; SOAP響應返回1個匹配文檔）

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

我想獲得的文件名（ICCFileName =「Golem_Artikel.txt」 ）和這個文件的URL（< 釐米：URL值=「http：//cmwin01.ebusiness.local：9080/icmrm/ICMResourceManager/A10 ...）在字符串變量使用Java。要做到這一點（Can't process SOAP response,How to do the Parsing of SOAP Response）但沒有成功。以下是我嘗試的：

import javax.xml.parsers.DocumentBuilder; 
import javax.xml.parsers.DocumentBuilderFactory; 

import org.w3c.dom.Document; 
import org.w3c.dom.Element; 
import org.w3c.dom.Node; 
import org.w3c.dom.NodeList; 
import org.xml.sax.InputSource; 

// Clean response xml document 
responseDocumentBody.normalizeDocument(); 
// Get result node 
NodeList resultList = responseDocumentBody.getElementsByTagName("ICCSPArchivSuche"); 
Element resultElement = (Element) resultList.item(0); 
String XMLData = resultElement.getTextContent(); 

// Check for empty result 
if ("Data Not Found".equalsIgnoreCase(XMLData)) 
    return null; 


DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); 
InputSource inputSource = new InputSource(); 
inputSource.setCharacterStream(new StringReader(XMLData)); 
Document doc = documentBuilder.parse(inputSource); 
Node node = doc.getDocumentElement(); 
String result = doc.getNodeType(); 


return result; 

從博尼塔，我只獲得responseDocumentBody或responseDocumentEnvelope（org.w3c.dom.Document）作爲web服務響應。因此，我需要從SOAP Body導航到我的變量。如果有人能幫忙，我會很高興。

如果你做了很多與此相關的工作，我會明確推薦使用JAXB，正如MGoron所建議的那樣。如果這僅僅是一個鏡頭，XPATH也可以很好地工作。

/* 
    * Must use a namespace aware factory 
    */ 
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); 
    dbf.setNamespaceAware(true); 
    Document doc = dbf.newDocumentBuilder().parse(...); 


    /* 
    * Create an XPath object 
    */ 
    XPath p = XPathFactory.newInstance().newXPath(); 

    /* 
    * Must use a namespace context 
    */ 
    p.setNamespaceContext(new NamespaceContext() { 

     public Iterator getPrefixes(String namespaceURI) { 
      return null; 
     } 

     public String getPrefix(String namespaceURI) { 
      return null; 
     } 

     public String getNamespaceURI(String prefix) { 
      if (prefix.equals("ns1")) 
       return "http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema"; 
      if (prefix.equals("cm")) 
       return "http://www.ibm.com/xmlns/db2/cm/api/1.0/schema"; 
      return null; 
     } 
    }); 

    /* 
    * Find the ICCSFileName attribute 
    */ 
    Node iccsFileName = (Node) p.evaluate("//ns1:ICCSPArchivSuche/@ICCFileName", doc, XPathConstants.NODE); 
    System.out.println(iccsFileName.getNodeValue()); 

    /* 
    * Find the URL 
    */ 
    Node url = (Node) p.evaluate("//ns1:ICCSPArchivSuche/cm:resourceObject/cm:URL/@value", doc, XPathConstants.NODE); 
    System.out.println(url.getNodeValue());

1. 得到RunQueryReply模式
2. 地圖XSD到Java類使用JAX-B
3. 解組應答串到JAX-B類對象

Answer 3

下面是代碼在VTD-XML要做到這一點，它基本上由2個XPath查詢，每區選出一個結果......然而，代碼是強大的，因爲它不承擔這些查詢將返回非空結果...

import com.ximpleware.*; 

public class parseSOAP { 
    public static void main(String[] s) throws VTDException, Exception{ 
     VTDGen vg = new VTDGen(); 
     vg.selectLcDepth(5);// soap has deep nesting so set to 5 to speed up navigation 
     if (!vg.parseFile("d:\\xml\\soap2.xml", true)) 
      return; 
     VTDNav vn = vg.getNav(); 
     AutoPilot ap =new AutoPilot(vn); 

     //declare name space for xpath 
     ap.declareXPathNameSpace("ns", "http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema"); 
     ap.declareXPathNameSpace("ns1", "http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema"); 
     ap.declareXPathNameSpace("cm", "http://www.ibm.com/xmlns/db2/cm/api/1.0/schema"); 
     ap.declareXPathNameSpace("soapenv", "http://www.w3.org/2003/05/soap-envelope"); 


     ap.selectXPath("/soapenv:Envelope/soapenv:Body/ns1:RunQueryReply/ns1:ResultSet/ns1:Item/ns1:ItemXML//ICCSPArchivSuche/@ICCFileName"); 
     int i=0; 
     if ((i=ap.evalXPath())!=-1){ 
      System.out.println("file name ==>"+vn.toString(i+1)); 
     } 

     ap.selectXPath("/soapenv:Envelope/soapenv:Body/ns1:RunQueryReply/ns1:ResultSet/ns1:Item/ns1:ItemXML//ICCSPArchivSuche/cm:resourceObject/cm:URL/@value"); 
     if ((i=ap.evalXPath())!=-1){ 
      System.out.println("file name ==>"+vn.toString(i+1)); 
     } 
    } 
}
