java后台调用webservice接口常用方式

最近在项目开发中遇到对接系统提供的接口为webservice接口，第一次调用webservice通过查询尝试了以下两种调用方式：
方式一：普通接口调用

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

public class texst {

    public static void main(String[] args) throws IOException, MalformedURLException {
        String url ="http://xxx.xxx.xxx.xxx:xxx/cwbase/jtgl/ys/YuSuanService.asmx";
        URL wsUrl = new URL(url);
        HttpURLConnection conn = (HttpURLConnection) wsUrl.openConnection();
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");
        conn.setConnectTimeout(5*1000);
        conn.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");
        conn.setRequestProperty("Content-Length", "length");
        conn.setRequestProperty("SOAPAction", "http://tempuri.org/YuSuanQuery");
        String req ="";
        req+="";
        req+="";
        req+="";
        req+="";
        req+="jkcs";
        req+="00010503";
        req+="202203";
        req+="0201";
        req+="660100030027";
        req+="660100030027";
        req+="";
        req+="";
        req+="";
        req+="";
        OutputStream os = conn.getOutputStream();
        os.write(req.getBytes());
//        OutputStreamWriter os = new OutputStreamWriter(conn.getOutputStream(), "utf-8");
//        os.write(String.valueOf(req.getBytes()));
        InputStream is = conn.getInputStream();
        byte[] b = new byte[1024];
        int len = 0;
        String s = "";
        while((len = is.read(b)) != -1){
            String ss = new String(b,0,len,"UTF-8");
            s += ss;
        }
        is.close();
        os.close();
        conn.disconnect();
        System.out.println("服务器返回数据:"+s);
    }
}

其中：YuSuanQuery 为方法名

方式二：借助wsdl
首先，找到本地jdk文件夹下的bin目录其中有个wsimport.exe就是借助改应用生成后端代码； wsimport.exe所在目录

其次在bin目录下打开cmd命令窗口如图：

在该目录下执行：

wsimport -s D:\ http://10.29.197.177:5200/cwbase/jtgl/ys/YuSuanService.asmx?wsdl

命令

命名执行完后会在D盘生成org文件夹里面有自动生成的java文件,将文件都复制到工程中主要使用以下两个java类进行接口调用即可
