Java calls return XML-formatted data webservice, and the application of XML parsing through XPath

First, get the WSDL definition and Endpoit address

The WSDL definition address is provided by the developer for Http://10.10.xx.xxx/webservice/Pangus.SCC.OracleEBS.WebService.dll/wsdl/IWebService

To access the WSDL address through the browser, you can see a description of the endpoint address:

<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>

Second, Eclipse generates Java WebService Client Agent

Eclipse->new->other->web Service Client-> Enter the WSDL address->finish.

The generated class code is (not including Ireelidservice.java and Reelidserviceimpl.java classes): 650) this.width=650; "Src=" http://ekp.scc.com.cn/ekp/ RESOURCE/FCKEDITOR/EDITOR/FILEMANAGER/DOWNLOAD?FDID=1407A9E548F74F6234FE80D481E8B3DC "width=" 291 "height=" 194 "/ >

Third, call the method provided by WebService

This example calls the Getimsdata method, which is called through the proxy class Iwebservicproxy.java, and the returned data is XML, which needs to be parsed

/**
* Call Pangu WMS System WebService to get reelid information
* Return format is a string that needs to be parsed by itself
* @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;
}

Iv. Parsing xml

Parses the returned XML data through XPath and wraps it into VO. XPath is a bit like jquery, which parses XML, and jquery is parsing the DOM, and the specific knowledge of XPath can be consulted: http://w3school.com.cn/xpath/

/**
* Parse the Reelid string returned by Pangu WMS WebService
* Format: <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 string
* @return Reelidvo
*/
Private Reelidvo Parsexmltovo (String reelidinfo) {
System.out.println (Reelidinfo);
Log.debug ("Reelidinfo =" + Reelidinfo);
try {
Documentbuilderfactory dbf = Documentbuilderfactory.newinstance ();
Documentbuilder builder = Dbf.newdocumentbuilder ();
adding XML definitions
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"));
Finding XML node data through XPath
Xpathfactory factory = Xpathfactory.newinstance ();
XPath XPath = Factory.newxpath ();
Reelid element text under the first row under a dataset under the root
XPathExpression expr = xpath.compile ("/dataset/row[1]//*");
NodeList nodes = (NodeList) expr.evaluate (Doc, Xpathconstants.nodeset);
if (null = = nodes) {
return null;
}
Reelidvo Reelidvo = new Reelidvo ();
Inventory Organization
Reelidvo.setorganizationid (long.valueof (Getnodevaluebynodename (nodes, "OrganizationId"));
Reelid
Reelidvo.setreelid (Getnodevaluebynodename (nodes, "reelid"));
Remaining quantity
Reelidvo.setremainqty (double.valueof (Getnodevaluebynodename (nodes, "QTY"));
Original quantity
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;
}
