一、直接AXIS呼叫遠端的web service

import java.util.LinkedList; 

import java.util.List; 

import java.util.Map;  

import java.util.Vector;  

import javax.xml.namespace.QName;  

import org.apache.axis.client.Call; 

import org.apache.axis.client.Service;

//private  String url="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx"

//private  String soapaction="http://WebXml.com.cn/";   //域名，這是在server定義的

public static String  getResult(String methodName,Map<String,Object> map){      
         Service service=new Service();
         String url = Constants.serveUrl;//提供介面的地址
         String soapaction = Constants.soapaction;//域名，這是在server定義的（具體見提供的asmx）
         String v= "";
         try{
             Call call=(Call)service.createCall();            
             call.setTargetEndpointAddress(url);            
             call.setOperationName(new QName(soapaction,methodName)); //設定要呼叫哪個方法
             Set set = map.entrySet();
             List<Object> list = new ArrayList<Object>();
             for(Iterator iter = set.iterator(); iter.hasNext();){
                  Map.Entry entry = (Map.Entry)iter.next();
                  String key = (String)entry.getKey();
                  String value = (String)entry.getValue();
                  if(key.equals("userId") || key.equals("genSetId")){//判斷引數，設定引數型別
                      call.addParameter(new QName(soapaction,key), //設定要傳遞的引數
                              org.apache.axis.encoding.XMLType.XSD_INT,javax.xml.rpc.ParameterMode.IN);
                  }else{
                      call.addParameter(new QName(soapaction,key), //設定要傳遞的引數
                              org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);
                  }
                  list.add(value);
             }
             call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//（標準的型別）
             call.setUseSOAPAction(true);
             call.setSOAPActionURI(soapaction+methodName);    
             v=(String)call.invoke(list.toArray());//呼叫方法並傳遞引數        
             System.out.println("result is "+v);
         }catch(Exception ex){
             ex.printStackTrace();
             v = "fail";
         }
        return v;        

     }

2、 HTTP POST 請求

public static String getWebSerResult(String methodname,Map<String,Object> map){
        String result = "";
        try {

            String urlStr = Constants.serveUrl;//提供介面的地址

            String soapaction = Constants.soapaction;//域名

            URL url = new URL(urlStr);
            HttpURLConnection con = (HttpURLConnection) url.openConnection();
            con.setDoInput(true);
            con.setDoOutput(true);
            con.setRequestMethod("POST");
            con.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");
            con.setConnectTimeout(30000);
            con.setReadTimeout(30000);
            con.connect();
            OutputStream oStream = con.getOutputStream();
            //下面這行程式碼是用字串拼出要傳送的xml，xml的內容是從測試軟體裡拷貝出來的
            //需要注意的是，有些空格不要弄丟哦，要不然會報500錯誤的。
            //引數什麼的，你可以封裝一下方法，自動生成對應的xml指令碼
            String soap = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"+
            "<soap:Envelope "+
            "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" "+ "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" "+ "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">"+
              "<soap:Body>"+
                "<SaveSetDateTimeCmd  xmlns=\""+soapaction+"\">"+
                  "<userId>1</userId>"+
                  "<ipAddress>170.0.0.1</ipAddress>"+
                  "<genSetId>1</genSetId>"+
                  "<cmdCode>11</cmdCode>"+
                  "<newDateTime>2018-05-28 10:54:00</newDateTime>"+
                "</SaveSetDateTimeCmd > "+
              "</soap:Body>"+
            "</soap:Envelope>";
            oStream.write(soap.getBytes());
            oStream.flush();

            oStream.close();

            InputStream iStream = con.getInputStream();
            Reader reader = new InputStreamReader(iStream);
            int tempChar;
            String str = new String();
            while((tempChar = reader.read()) != -1){
                str += (char) tempChar;
            }
            iStream.close();
            oStream.close();
            con.disconnect();
            System.out.println(">>>>>>returnedxmlstr:"+str);
            Map<String,Object> remap = parseXmlToList(str);
            System.out.println("**********remap**********:"+remap);
            result = (String) remap.get("Body");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            result = "fail";
        }
        return result;
    }
