java代码实现webservice客户端

老规矩，先贴上代码，再解释

package cn.sh.ideal.portal.interfaces.util.beiji; import java.net.MalformedURLException; import java.net.URL; import java.rmi.RemoteException; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import javax.xml.namespace.QName; import javax.xml.rpc.ParameterMode; import javax.xml.rpc.ServiceException; import net.sf.json.JSONArray; import org.apache.axis.Constants; import org.apache.axis.client.Call; import org.apache.axis.client.Service; import org.apache.axis.client.Stub; import org.apache.axis.encoding.XMLType; import org.apache.axis.soap.SOAPConstants; import cn.sh.ideal.portal.cms.content.domain.DaibanView; public class HyjfClient extends Stub{ private String endpoint_1="http://************?wsdl"; private String url="http://************************"; private List<Call> calls = new ArrayList<Call>(); //构造器实现连接接口中的三个方法，并添加到list集合 public HyjfClient() throws ServiceException, MalformedURLException{ if(service ==null ){ service = new Service(); } Call call1=(Call)service.createCall(); call1.setOperationName(new QName(url, "getChannelList")); call1.setEncodingStyle(Constants.URI_SOAP11_ENC); call1.setSOAPVersion(SOAPConstants.SOAP11_CONSTANTS); call1.setTargetEndpointAddress(new URL(endpoint_1)); call1.setUseSOAPAction(true); call1.setSOAPActionURI(""); call1.setReturnType(XMLType.XSD_STRING); calls.add(call1);//添加getChannelList方法 Call call2=(Call)service.createCall(); call2.setOperationName(new QName(url, "getTodoList")); call2.setEncodingStyle(Constants.URI_SOAP11_ENC); call2.setSOAPVersion(SOAPConstants.SOAP11_CONSTANTS); call2.setTargetEndpointAddress(new URL(endpoint_1)); call2.setUseSOAPAction(true); call2.setSOAPActionURI(""); call2.setReturnType(XMLType.XSD_STRING); call2.addParameter(new QName("", "json"), new QName("http://www.w3.org/2001/XMLSchema", "string"), String.class,ParameterMode.IN); calls.add(call2);//getTodoList方法 Call call3=(Call)service.createCall(); call3.setOperationName(new QName(url, "articleOperator")); call3.setEncodingStyle(Constants.URI_SOAP11_ENC); call3.setSOAPVersion(SOAPConstants.SOAP11_CONSTANTS); call3.setTargetEndpointAddress(new URL(endpoint_1)); call3.setUseSOAPAction(true); call3.setSOAPActionURI(""); call3.setReturnType(XMLType.XSD_STRING); call3.addParameter(new QName("", "json"), new QName("http://www.w3.org/2001/XMLSchema", "string"), String.class,ParameterMode.IN); call3.setReturnType(XMLType.XSD_STRING); calls.add(call3);//articleOperator方法 } /** * 获得栏目列表 * @return * @throws RemoteException */ public String getChannelList() throws RemoteException { return (String) calls.get(0).invoke(new Object[]{}); } /** * 待办 * @param json * @return * @throws RemoteException */ public String getTodoList(String json) throws RemoteException{ return (String)calls.get(1).invoke(new Object[]{json}); } /** * 信息添加 * @param json * @return * @throws RemoteException */ public String articleOperator(String json) throws RemoteException{ String jsonw=json; return (String)calls.get(2).invoke(new Object[]{jsonw}); } public static void main(String[] args) { try { HyjfClient client = new HyjfClient(); System.out.println(client.getTodoList("{}")); String todo=client.getTodoList("{}");//调用接口方法并传入“{}”参数 JSONArray todolist = JSONArray.fromObject(todo);//获得接口返回值并且json格式化 //json格式转java集合 List<DaibanView> list = Arrays.asList((DaibanView[])JSONArray.toArray(todolist,DaibanView.class)); System.out.println(list.get(0).getContent()); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ServiceException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (RemoteException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }

上述代码通过axis实现手写webservice接口。
