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

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:

<?xml version="1.0" encoding="UTF-8"?><!-- Published by JAX-WS RI at http://jax-ws.dev.java.net. RI's version is JAX-WS RI 2.1.1 in JDK 6. --><!-- Generated by JAX-WS RI at http://jax-ws.dev.java.net. RI's version is JAX-WS RI 2.1.1 in JDK 6. --><definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.hua-xia.com.cn/ZySearch" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://www.hua-xia.com.cn/ZySearch" name="UserLinkWebServiceService">

<soap:address location="http://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:

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:

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,会认为传入的参数为null
			call.addParameter("linkNo",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,会认为传入的参数为null
call.addParameter("linkNo",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.

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("&lt;","<").replaceAll("&gt;",">");
               
            }
            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();
        }

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
