java调用.net asmx / wcf

一、先用asmx与wcf写二个.net web service:

1.1 asmx web服务：asmx-service.asmx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

namespace WebServiceSample
{
    /// <summary>
    /// Summary description for asmx_service
    /// </summary>
    [WebService(Namespace = "http://yjmyzz.cnblogs.com/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class asmx_service : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld(String msg)
        {
            return "Hello " + msg + " !";
        }
    }
}

1.2 wcf服务：wcf-service.svc.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.Web.Services;

namespace WebServiceSample
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "wcf_service" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select wcf-service.svc or wcf-service.svc.cs at the Solution Explorer and start debugging.
    [ServiceContract(Namespace="http://yjmyzz.cnblogs.com/")]
    [ServiceBehavior(Namespace = "http://yjmyzz.cnblogs.com/")]
    public class wcf_service
    {
        [OperationContract]
        public String HelloWorld(String msg)
        {
            return "Hello " + msg + " !";
        }
    }
}

1.3 web.config采用默认设置：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.5.1" />
    <httpRuntime targetFramework="4.5.1" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
      multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
</configuration>

完成后，访问网址为：

http://localhost:16638/asmx-service.asmx

http://localhost:16638/wcf-service.svc

二、java端的调用：

2.1 pom.xml中先添加以下依赖项：

<dependency>
            <groupId>org.apache.axis</groupId>
            <artifactId>axis</artifactId>
            <version>1.4</version>            
        </dependency>

        <dependency>
            <groupId>org.apache.axis</groupId>
            <artifactId>axis-jaxrpc</artifactId>
            <version>1.4</version>            
        </dependency>

        <dependency>
            <groupId>wsdl4j</groupId>
            <artifactId>wsdl4j</artifactId>
            <version>1.6.3</version>            
        </dependency>

        <dependency>
            <groupId>commons-discovery</groupId>
            <artifactId>commons-discovery</artifactId>
            <version>0.5</version>            
        </dependency>

        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.1.3</version>            
        </dependency>

2.2 asmx web service的调用：

先封装一个方法：

    String callAsmxWebService(String serviceUrl, String serviceNamespace,
            String methodName, Map<String, String> params)
            throws ServiceException, RemoteException, MalformedURLException {

        org.apache.axis.client.Service service = new org.apache.axis.client.Service();
        Call call = (Call) service.createCall();
        call.setTargetEndpointAddress(new java.net.URL(serviceUrl));
        call.setOperationName(new QName(serviceNamespace, methodName));

        ArrayList<String> paramValues = new ArrayList<String>();
        for (Entry<String, String> entry : params.entrySet()) {
            call.addParameter(new QName(serviceNamespace, entry.getKey()),
                    XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
            paramValues.add(entry.getValue());
        }

        call.setReturnType(XMLType.XSD_STRING);
        call.setUseSOAPAction(true);
        call.setSOAPActionURI(serviceNamespace + methodName);

        return (String) call.invoke(new Object[] { paramValues.toArray() });

    }

然后就可以调用了：

    @Test
    public void testCallAsmx() throws RemoteException, ServiceException,
            MalformedURLException {        

        Map<String, String> params = new HashMap<String, String>();
        params.put("msg", "yjmyzz");

        String result = callAsmxWebService(
                "http://localhost:16638/asmx-service.asmx",
                "http://yjmyzz.cnblogs.com/", "HelloWorld", params);

        System.out.println(result);
    }

2.3 wcf服务的调用：

这个要借助IDE环境生成代理类(或者用命令JAVA_HOMEinwsimport.exe -s  c: estjavasrc http://xxx.com/xxx.svc?wsdl)

eclipse环境中，project上右击->New->Other->Web Service Client

输入wsdl的地址，注意：wcf会生成二个wsdl的地址，用xxx?singleWsdl这个，如下图：

直接Finish，会生成一堆java文件：

然后就能调用啦：

    @Test
    public void testCallWcf() throws RemoteException, ServiceException,
            MalformedURLException {        
        
        Wcf_service_ServiceLocator locator = new Wcf_service_ServiceLocator();
        locator.setBasicHttpBinding_wcf_serviceEndpointAddress("http://localhost:16638/wcf-service.svc");
        System.out.println(locator.getBasicHttpBinding_wcf_service().helloWorld("jimmy"));         
    }
