Java调用wcf

最近正在学习wcf,java平台、android、mac都要调用，今天先弄个java调用测试下。

一、创建WCF

namespace YourNamespace
{
    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IHello”。
    [ServiceContract(Namespace = "http://xxx.com/")]
    public interface IHello
    {
        [OperationContract]
        string SayHello(string words);

        [OperationContract]
        string Test();

    }
}

namespace YourNamespace
{
    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码、svc 和配置文件中的类名“Hello”。
    public class Hello : IHello
    {
        public string SayHello(string words)
        {
            return "hello " + words;
        }

        public string Test()
        {
            return "test wcf";
        }
    }
}

<%@ ServiceHost Language="C#" Debug="true" Service="YourNamespace.Hello" CodeBehind="Hello.svc.cs" %>

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <serviceHostingEnvironment>
      <serviceActivations >
        <add relativeAddress="Hello.svc" service="YourNamespace.Hello"/>
      </serviceActivations >
    </serviceHostingEnvironment >

    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBindingCfg" closeTimeout="00:01:00"

            bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
            maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"
            messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
            allowCookies="false">
          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
              maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None"
                realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

    <services>
      <service name="YourNamespace.Hello" behaviorConfiguration="ServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:90/Hello"/>
          </baseAddresses>
        </host>
        <endpoint binding="basicHttpBinding" contract="YourNamespace.IHello">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <system.web>
    <compilation debug="true" />
  </system.web>
</configuration>

二、Java客户端调用

1.下载ksoap2 下载地址 http://code.google.com/p/ksoap2-android/

2.创建Java项目添加该类

package com.xx.wcftest;

import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

/**
 * 调用wcf服务类
 * @author awei
 *
 */
public class SoapService {
    
    /**
     * wcf服务命名空间
     */
    protected String NameSpace = "http://xxx.com/";//可从配置文件读取
    
    /**
     * wcf 服务地址
     */
    protected String URL = "http://localhost:90/";//可从配置文件读取
    
    /**
     * wcf soap 方法执行地址,可从wsdl中获取
     */
    protected String SOAP_ACTION;
    
    /**
     * 功能名称
     */
    protected String MethodName;
    
    /**
     * 构造器初始化参数
     * @param svc 服务寄宿文件名称 如：Hello.svc
     * @param ServiceInterface 服务接口名称 如：IHello
     */
    public SoapService(String svc,String ServiceInterface)
    {
        this.URL += svc;
        this.SOAP_ACTION = this.NameSpace + ServiceInterface + "/";
    }

    /**
     * 调用wcf方法返回结果
     * @param method 要调用的方法名称
     * @param map 要调用的方法参数字典
     * @return 
     */
    public SoapObject LoadResult(String method,Map<String, Object> map) {
        this.MethodName = method;
        SoapObject soapObject = new SoapObject(NameSpace, MethodName);
        if(map != null && map.size() != 0){
            Iterator<Entry<String, Object>> iter = map.entrySet().iterator();
            while (iter.hasNext()) {
                Map.Entry<String,Object> entry = iter.next();
                soapObject.addProperty(entry.getKey().toString(),entry.getValue());
                }
        }
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); // 版本
        envelope.bodyOut = soapObject;
        envelope.dotNet = true;
        envelope.setOutputSoapObject(soapObject);
        
        HttpTransportSE trans = new HttpTransportSE(URL);
        trans.debug = true; // 使用调试功能
        
        try {
            trans.call(SOAP_ACTION + this.MethodName, envelope);
            System.out.println("Call Successful!");
        } catch (Exception e) {
            System.out.println("IOException");
            e.printStackTrace();
        } 
        SoapObject result = (SoapObject) envelope.bodyIn;
        
        return result;
    }
    
}

3.调用服务

public class HelloWcfTest {

    public static void main(String[] args) {
        //1.创建服务对象
        SoapService service = new SoapService("Hello.svc","IHello");
        
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("words", "awei");//SayHello方法的参数
        
        SoapObject result = service.LoadResult("SayHello", map);
        System.out.println("WCF Test返回的数据是：" + result.getProperty(0));
        
        result = service.LoadResult("SayHello", null);
        System.out.println("WCF Test返回的数据是：" + result.getProperty(0));
    }
}
