axis,jax-ws,xfire客户端调用分析,以及webservice万能客户端
2011-09-13 21:42 [小 大] 来源: 未知 转发至：       
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:

</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.bussserv.common; 本文来自高级人才网gjrencai.com 

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 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) {

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;

  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);

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";

            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");

        }catch(Exception e){
        
         e.printStackTrace();

4.jax-ws调用

最后再写上一个jax-ws的client代码

import java.util.Map;
