ofbiz的webservice接口提供（3）-不规范的wsdl的客户端访问代码

针对上个模块提到的ofbiz的wsdl确实不是很规范，那么我们使用axis客户端工具生成的代码肯定不可用，这里我提供了我的客户端调用代码：

import java.util.*;
import java.net.*;
import java.rmi.*;
import javax.xml.namespace.*;
import javax.xml.rpc.*;
import org.apache.axis.Message;
import org.apache.axis.message.RPCElement;
import org.apache.axis.message.RPCParam;
import org.apache.axis.message.SOAPEnvelope;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class AxisClient {
/**
* 将我们的消息在控制台System.out打印出来
* */
private static Map getResponseParams(Message respMessage) {
Map mRet = new Hashtable();
try {
SOAPEnvelope resEnv = respMessage.getSOAPEnvelope();
List bodies = resEnv.getBodyElements();
Iterator i = bodies.iterator();
while (i.hasNext()) {
Object o = i.next();
if (o instanceof RPCElement) {
RPCElement body = (RPCElement) o;
List params = null;
params = body.getParams();
Iterator p = params.iterator();
while (p.hasNext()) {
RPCParam param = (RPCParam) p.next();
mRet.put(param.getName(), param.getValue());
System.out.println("SOAP Client Param - " + param.getName() + "=" + param.getValue());
}
}
}
} catch (org.apache.axis.AxisFault e) {
System.out.println("AxisFault");
} catch (org.xml.sax.SAXException e) {
System.out.println("SAXException");
}
return mRet;
}

public static void main(String[] args) {
String message = "";
Map output;

String endpoint;
try {
//指明我们的服务点
endpoint = "http://192.168.20.32/projectname/control/SOAPService/";
Call call = (Call) new Service().createCall();
call.setTargetEndpointAddress(new URL(endpoint));
//指明要调用的服务名称
call.setOperationName(new QName("findSeniorService", "findSeniorService"));
//指明服务的输出输出参数
call.addParameter("userid",
org.apache.axis.Constants.XSD_STRING,
javax.xml.rpc.ParameterMode.INOUT);
call.addParameter("salt",
org.apache.axis.Constants.XSD_STRING,
javax.xml.rpc.ParameterMode.IN);
call.addParameter("aaa",
org.apache.axis.Constants.XSD_STRING,
javax.xml.rpc.ParameterMode.OUT);
call.addParameter("bbb",
org.apache.axis.Constants.XSD_STRING,
javax.xml.rpc.ParameterMode.OUT);
call.addParameter("ccc",
org.apache.axis.Constants.XSD_STRING,
javax.xml.rpc.ParameterMode.OUT);
call.setReturnType(org.apache.axis.Constants.XSD_STRING);
//传递参数，发起调用
Object responseWS = call.invoke(new Object[]{"123456789", "aaa"});
System.out.println( "Receiving response: " +  (String) responseWS);
output = call.getOutputParams();
getResponseParams(call.getMessageContext().getResponseMessage());
} catch (MalformedURLException ex) {
message = "error: wrong url";
} catch (ServiceException ex) {
message = "error: failed to create the call";
} catch (RemoteException ex) {
ex.printStackTrace();
message = "error: failed to invoke WS";
} finally {
System.out.println("");
System.out.println(message);
}
}
}

注意上边的endpoint的链接要根据你服务器部署的实际情况来书写。
同时我也提供下xmlspy根据链接生成的数据包，这个不可用：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<salt xsi:type="xsd:string">String</salt>
<userid xsi:type="xsd:string">String</userid>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

看到上边那个生成的不可用的文件主要是没指定服务方法，我们手工改一下，并将我们的参数值奉上：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<findSeniorService xmlns="http://ofbiz.apache.org/service/">
<salt xsi:type="xsd:string">aaa</salt>
<userid xsi:type="xsd:string">2222</userid>
</findSeniorService>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

看上边只是指定了我们要给哪个方法传送参数“<findSeniorService xmlns="http://ofbiz.apache.org/service/">”
然后发送soap的信息到webservice接口，我这里的返回值如下：

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<ns1:findSeniorServiceResponse xmlns:ns1="http://ofbiz.apache.org/service/">
<aaa xsi:type="xsd:string">test_aaaaa</aaa>
<bbb xsi:type="xsd:string">test_bbbbb</bbb>
<ccc xsi:type="xsd:string">test_ccccc</ccc>
<userid xsi:type="xsd:string">2222</userid>
</ns1:findSeniorServiceResponse>
</soapenv:Body>
</soapenv:Envelope>

这样我就验证了虽然ofbiz提供的webservice的wsdl很不好用，但是那个webservice接口还是可以使用的。只不过只是支持基础数据类型而已。
