我有这个类，它只发送一个 http post 请求：

import java.net.*; import java.io.*;
public class JarRuntimeTest{
    public void start() throws Exception{
        HttpURLConnection connection = (HttpURLConnection) (new URL("https://google.com").openConnection());
        connection.setRequestMethod("POST");
        System.out.println(
        getResult((connection.getResponseCode() == HttpURLConnection.HTTP_OK)?
        connection.getInputStream():connection.getErrorStream()));
    }
    public String getResult(InputStream in) throws Exception{
        StringBuilder builder = new StringBuilder("");
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));
        String line = null;
        while ((line = reader.readLine()) != null) builder.append(line);
        reader.close();
        return builder.toString();
    }
    public static void main(String[] args){try{new JarRuntimeTest().start();}catch(Exception e){e.printStackTrace();}}
}

我有这个.bat文件，它为其构建 jar 和 java 运行时映像，并使用此自定义运行时映像来运行我的 jar：
