1、在子模块DSInfoservice代码编写

(1) 在test文件目录下创建一个DsClienttest类

DsClienttest.java

package com.youfan.test;

import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;

public class DsClienttest {
    public static void main(String[] args) {
        String message="test";
        String adress="http://127.0.0.1:6097/DsInfoSJService/webInfoSJService";

     try {
         URL url=new URL(adress);
         HttpURLConnection conn=(HttpURLConnection)url.openConnection();
         conn.setRequestMethod("POST");
         conn.setDoInput(true);
         conn.setDoOutput(true);
         conn.setAllowUserInteraction(true);
         conn.setUseCaches(false);  //关闭缓存
         conn.setReadTimeout(6*1000); //设置时间
         conn.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36");  //设置浏览器请求
         conn.setRequestProperty("content-type","application/x-javascript");
         conn.connect();
         OutputStream outputStream = conn.getOutputStream();
         BufferedOutputStream out = new BufferedOutputStream(outputStream);
         out.write(message.getBytes());
         out.flush();
          String temp="";
         InputStream in = conn.getInputStream();
         byte[]tempbytes=new byte[1024];
         while (in.read(tempbytes,0,1024)!=-1){
          temp+=new String(tempbytes);
         }
         System.out.println(conn.getResponseCode());
         System.out.println(temp);

     }catch (Exception e){
         e.printStackTrace();
     }
     }
}

(2) 先启动主程序类，后启动DsClienttest 类，控制台打印日志信息：


其中,这两个参数的由来

 conn.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36");  //设置浏览器请求
 conn.setRequestProperty("content-type","application/x-javascript");

如图所示：
