axis,jax-ws,xfire客户端调用分析,以及webservice万能客户端

2012-10-15 17:39 471 查看
最近一个项目需要调用一个webservice接口,遇到一个问题.项目中的jdom版本为0.9.而webservice client需要用到jdom1.0 如果将jdom版本升级则会造成现有系统异常.

因此需要在不改变现有项目jar的情况下解决这个问题.service端使用的jax-ws2.

wsdl如下:

Java代码

1.xfire调用

对方给我们的client是使用xfire的client调用,代码如下:

Java代码







package com.zhongying.bussserv.common; import java.net.URL; import java.util.Map; import org.codehaus.xfire.client.Client; import com.thoughtworks.xstream.XStream; import com.thoughtworks.xstream.io.xml.DomDriver; public class Test { public static void main(String[] args) { String url = "http://192.168.1.1:8000/RES_Searcher/service/IUserLinkWebService?wsdl"; Client client; try { client = new Client(new URL(url)); Object params[] = {"123456"}; String result = (String)client.invoke("getUserLink", params)[0]; XStream xStream = new XStream(new DomDriver()); Map map = (Map)xStream.fromXML(result); } catch (Exception e) { e.printStackTrace(); } } }
package com.zhongying.bussserv.common;

import java.net.URL;
import java.util.Map;
import org.codehaus.xfire.client.Client;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class Test {

public static void main(String[] args) {

String url = "http://192.168.1.1:8000/RES_Searcher/service/IUserLinkWebService?wsdl";

Client client;
try {
client = new Client(new URL(url));
Object params[] = {"123456"};
String result = (String)client.invoke("getUserLink", params)[0];
XStream xStream = new XStream(new DomDriver());
Map map = (Map)xStream.fromXML(result);
} catch (Exception e) {

e.printStackTrace();
}
}

}


2.axis调用

但是由于jar包的原因,我们不能使用上面的方法,想出的第一个解决方案是使用axis的客户端来调用接口,代码如下:

Java代码







import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;
import javax.xml.namespace.QName;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class TestReflection {

public static void main(String[] arg) {

String url = "http://192.168.1.1:9010/ZySearch";

try {

Service service = new Service();
Call call = (Call) service.createCall();
// 设置调用服务地址
call.setTargetEndpointAddress(new java.net.URL(url));

//此处一定要配置wsdl的namespace参数http://www.hua-xia.com.cn/ZySearch

call.setOperationName(new QName("http://www.hua-xia.com.cn/ZySearch", "getUserLink"));

//此处需要配置传入参数类型与参数名称,如果未设置jax-ws则无法接受参数,会认为传入的参数为null

call.addParameter("linkNo",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);
//如果设置类传入参数类型,此处也需要设置返回参数类型

call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
call.setUseSOAPAction(true);
call.setSOAPActionURI(url);

String result = (String) call.invoke(new Object[] { "AD0006526305" });

XStream xStream = new XStream(new DomDriver());
Map map = (Map) xStream.fromXML(result);

Iterator it = map.entrySet().iterator();

while (it.hasNext()) {

Map.Entry enty = (Entry) it.next();

System.out.println(enty.getKey() + ":" + enty.getValue());

}
} catch (Exception e) {

e.printStackTrace();
}

}
}

import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;
import javax.xml.namespace.QName;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class TestReflection {

public static void main(String[] arg) {

String url = "http://192.168.1.1:9010/ZySearch";

try {

Service service = new Service();
Call call = (Call) service.createCall();
// 设置调用服务地址
call.setTargetEndpointAddress(new java.net.URL(url));

//此处一定要配置wsdl的namespace参数http://www.hua-xia.com.cn/ZySearch
call.setOperationName(new QName("http://www.hua-xia.com.cn/ZySearch", "getUserLink"));

//此处需要配置传入参数类型与参数名称,如果未设置jax-ws则无法接受参数,会认为传入的参数为null
call.addParameter("linkNo",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);
//如果设置类传入参数类型,此处也需要设置返回参数类型
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
call.setUseSOAPAction(true);
call.setSOAPActionURI(url);

String result = (String) call.invoke(new Object[] { "AD0006526305" });

XStream xStream = new XStream(new DomDriver());
Map map = (Map) xStream.fromXML(result);

Iterator it = map.entrySet().iterator();

while (it.hasNext()) {

Map.Entry enty = (Entry) it.next();

System.out.println(enty.getKey() + ":" + enty.getValue());

}
} catch (Exception e) {

e.printStackTrace();
}

}
}


测试后发现,此方式可以调用xfire和jax-ws的service,但是如果未设置传入参数类型名称,jax-ws认为传入的参数为null.所以一下步骤在调用jax-ws的service时一定要设置

//此处需要配置传入参数类型与参数名称,如果未设置jax-ws则无法接受参数,会认为传入的参数为null

call.addParameter("linkNo",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);

//如果设置类传入参数类型,此处也需要设置返回参数类型

call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);

call.setUseSOAPAction(true);

call.setSOAPActionURI(url);

3.http模拟调用

由于开始对axis的了解有限,在写axis调用是总是有问题,于是便想了另外一个方法,这个方法有点剑走偏锋.但是适用性却很强,因为调用的是java自带的api不会产生兼容性问题.

大家知道webservice请求实际上也就是一个http请求,将数据通过xml文件进行交换.

既然知道了原理我们就可以模拟一个http请求来调用webservice.

Java代码







try{

String url2 = "http://192.168.1.1:9010/ZySearch?wsdl";

URL getUrl = new URL(url2);

HttpURLConnection connection = (HttpURLConnection) getUrl.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-type","text/xml");

connection.setRequestProperty("Accept","text/xml");
connection.setRequestProperty("User-Agent","JAX-WS RI 2.1.3-hudson-390-");

String send="<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"><soap:Body><ns1:getUserLink xmlns:ns1=\"http://www.hua-xia.com.cn/ZySearch\"><linkNo xmlns=\"\">"+par+"</linkNo></ns1:getUserLink></soap:Body></soap:Envelope>";

connection.getOutputStream().write(send.getBytes());
connection.getOutputStream().flush();
connection.getOutputStream().close();
connection.connect();
// 取得输入流，并使用Reader读取
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8"));//设置编码,否则中文乱码

System.out.println("=============================");
System.out.println("Contents of get request");
System.out.println("=============================");
String lines="";
String reuslts = "";
while ((lines = reader.readLine()) != null){
//lines = new String(lines.getBhqytes(), "utf-8");

reuslts+=lines.replaceAll("<", "<").replaceAll(">", ">");

}
reader.close();

System.out.println("type:"+connection.getContentType());
// 断开连接
connection.disconnect();

System.out.println(reuslts);
System.out.println("=============================");
System.out.println("Contents of get request ends");
System.out.println("=============================");

XStream xStream = new XStream(new DomDriver());

reuslts = reuslts.substring(reuslts.indexOf("<returnVal>")+11);

reuslts = reuslts.substring(0,reuslts.indexOf("</returnVal>"));

System.out.println(reuslts);

Map result = (Map)xStream.fromXML(reuslts);

Iterator it = result.entrySet().iterator();

while(it.hasNext()){

Map.Entry enty = (Entry) it.next();

System.out.println(enty.getKey()+":"+enty.getValue());

}

}catch(Exception e){

e.printStackTrace();
}

try{

String url2 = "http://192.168.1.1:9010/ZySearch?wsdl";

URL getUrl = new URL(url2);

HttpURLConnection connection = (HttpURLConnection) getUrl.openConnection();
connection.setDoOutput(true);

System.out.println(reuslts);

System.out.println("=============================");

XStream xStream = new XStream(new DomDriver());

reuslts = reuslts.substring(reuslts.indexOf("<returnVal>")+11);

reuslts = reuslts.substring(0,reuslts.indexOf("</returnVal>"));

System.out.println(reuslts);

Map result =  (Map)xStream.fromXML(reuslts);

Iterator it = result.entrySet().iterator();

while(it.hasNext()){

Map.Entry enty = (Entry) it.next();

System.out.println(enty.getKey()+":"+enty.getValue());

}

}catch(Exception e){

e.printStackTrace();
}


上面的参数send可以在使用jax-ws客户端发送请求的时候,使用sniff工具截取,然后仿造自己构造一个.使用这种方式客户忽略service是何种方式,对于任何webservice都可以实现调用,只是麻烦了一点,但是在无路可走的情况下,也不失为一种选择!

4.jax-ws调用

最后再写上一个jax-ws的client代码

Java代码







import java.net.MalformedURLException;
import java.util.Map;

import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPBodyElement;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.BindingProvider;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;
import javax.xml.ws.WebServiceException;
import javax.xml.ws.soap.SOAPBinding;

public class Client {
// 名字空间
public static final String targetNamespace = "http://www.hua-xia.com.cn/ZySearch";

//服务名
public static final String serName = "UserLinkWebServiceService";
//端口名
public static final String pName = "UserLinkWebServicePort";
//服务地址
public static final String endpointAddress = "http://192.168.1.1:9010/ZySearch?wsdl";

//方法名
public static final String OPER_NAME = "getUserLink";
//参数名
public static final String INPUT_NMAE = "linkNo";
/**
* @param args
* @throws MalformedURLException
* @throws Exception
*/
public static void main(String[] args) throws MalformedURLException, Exception {

// TODO Auto-generated method stub

QName serviceName = new QName(targetNamespace, serName);

QName portName = new QName(targetNamespace, pName);

javax.xml.ws.Service service = Service.create(serviceName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointAddress);

Dispatch<SOAPMessage> dispatch = service.createDispatch(portName,
SOAPMessage.class, Service.Mode.MESSAGE);

BindingProvider bp = (BindingProvider) dispatch;
Map<String, Object> rc = bp.getRequestContext();
rc.put(BindingProvider.SOAPACTION_USE_PROPERTY, Boolean.TRUE);
rc.put(BindingProvider.SOAPACTION_URI_PROPERTY, OPER_NAME);
MessageFactory factory = ((SOAPBinding)bp.getBinding()).getMessageFactory();

SOAPMessage request = factory.createMessage();
SOAPBody body = request.getSOAPBody();
QName payloadName = new QName(targetNamespace, OPER_NAME, "ns1");
SOAPBodyElement payload = body.addBodyElement(payloadName);

SOAPElement message = payload.addChildElement(INPUT_NMAE);
message.addTextNode("AD0006526305");
SOAPMessage reply = null;

try
{
reply = dispatch.invoke(request);
}
catch (WebServiceException wse)
{
wse.printStackTrace();
}
SOAPBody soapBody = reply.getSOAPBody();
SOAPBodyElement nextSoapBodyElement = (SOAPBodyElement)soapBody.getChildElements().next ();
SOAPElement soapElement = (SOAPElement)nextSoapBodyElement.getChildElements().next();

System.out.println("获取回应信息为：" + soapElement.getValue());

}
