这里搭建WebService采用JDKService那种最简单的方式，在此博文中不再说明。

以前说过，调用javaw的API封包是这样的：

这里模拟下。

客户端结构如下：

源码如下：

Main2.java

package webservice.client;
    
    import java.io.IOException;
    import java.io.InputStream;
    import java.net.HttpURLConnection;
    import java.net.URL;
    import java.util.Scanner;
    
    public class Main2 {
    
        public static void main(String[] args) throws IOException {
    
            URL url = new URL("http://localhost:9998/weatherService?wsdl");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
    
            //打开通信
            connection.setDoInput(true);
            connection.setDoOutput(true);
    
            //拼接符合协议需求的数据格式
            String info = buildXML("南京");
            connection.getOutputStream().write(info.getBytes());
    
            int responseCode = connection.getResponseCode();
    
            if(responseCode == 200){
    
                //正常
                InputStream inputStream = connection.getInputStream();
                Scanner sc = new Scanner(inputStream);
                while(sc.hasNext()){
    
                    System.out.println(sc.nextLine());
                }
                sc.close();
            }
            else{
    
                System.out.println(responseCode);
            }
            System.out.println("over");
        }
    
        private static String buildXML(String cityName){
    
            String str = "<?xml version=\"1.0\" ?><S:Envelope xmlns:S=\"http://schemas.xmlsoap.org/soap/envelope/\"><S:Body><ns2:query xmlns:ns2=\"http://webservice/\"><arg0>";
            str += cityName;
            str += "</arg0></ns2:query></S:Body></S:Envelope>";
    
            return str;
        }
    }
