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<?xml version="1.0" encoding="UTF-8"?><!-- Published by JAX-WS RI at jax-ws.dev.java. RI's version is JAX-WS RI 2.1.1 in JDK 6. --><!-- Generated by JAX-WS RI at jax-ws.dev.java. RI's version is JAX-WS RI 2.1.1 in JDK 6. --><definitions xmlns:soap="/wsdl/soap/" xmlns:tns="www.hua-xia/ZySearch" xmlns:xsd="/2001/XMLSchema" xmlns="/wsdl/" targetNamespace="www.hua-xia/ZySearch" name="UserLinkWebServiceService">

</input>
<output>

</operation>
</binding>

<soap:address location="192.168.1.1.154:9010/ZySearch"></soap:address>
</port>
</service>
</definitions>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.bussservmon;
import java.URL;
import java.util.Map;
dehaus.xfire.client.Client;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.l.DomDriver;
public class Test {

 public static void main(String[] args) {
 
        String url = "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;
l.namespace.QName;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.l.DomDriver;
public class TestReflection {
 public static void main(String[] arg) {
  String url = "192.168.1.1:9010/ZySearch";
  try {
   Service service = new Service();
   Call call = (Call) ateCall();
   // 设置调用服务地址
   call.setTargetEndpointAddress(new java.URL(url));
   
   //此处一定要配置wsdl的namespace参数www.hua-xia/ZySearch
   call.setOperationName(new QName("www.hua-xia/ZySearch", "getUserLi
nk"));
   //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.ding.XMLType.XSD_l.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.ding.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 = Set().iterator();
   while (it.hasNext()) {
    Map.Entry enty = (Entry) it.next();
    System.out.Key() + ":" + Value());
   }
  } catch (Exception e) {
   e.printStackTrace();
  }
 }
}
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.如何生成webservice客户端但是适用性却很强,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 = "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=\"/soap/envelope/\" xmlns:xsd=\"/2001/XMLSchema\" xmlns:xsi=\"/2001/XMLSchema-instance\"><soap:Body><ns1:getUserLink xmlns:ns1=\"www.hua-xia/ZySearch\"><linkNo xmlns=\"\">"+par+"</linkNo></ns1:getUserLink></soap:Body></soap:Envelope>";
            OutputStream().Bytes());
            OutputStream().flush();
            OutputStream().close();
            t();
            // 取得输入流，并使用Reader读取
            BufferedReader reader = new BufferedReader(new InputStream(),"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 = adLine()) != null){
                    //lines = new Bhqytes(), "utf-8");
            reuslts+=placeAll("<", "<").replaceAll(">", ">");
             
            }
            reader.close();
           
           
           
            System.out.println("type:"+ContentType());
            // 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 = Set().iterator();
     
        while(it.hasNext()){
       
       Map.Entry enty = (Entry) it.next();
       
       System.out.Key()+":"+Value());
       
        }
       
        }catch(Exception e){
       
        e.printStackTrace();
        }
