HtmlSaveUtil.java

import java.io.*;
    import java.net.URL;
    
    public class HtmlSaveUtil {
    
        public static void saveHtml(String filepath, String str) throws IOException {
            //字节输出流
            FileOutputStream fos = new FileOutputStream(new File(filepath));
            //接收字节输入流
            InputStream is =  new URL(str).openStream();
            //为字节输入流加缓冲
            BufferedInputStream bis = new BufferedInputStream(is);
            //为字节输出流加缓冲
            BufferedOutputStream bos = new BufferedOutputStream(fos);
            int length;
            byte[] bytes = new byte[1024*20];
            while((length = bis.read(bytes, 0, bytes.length)) != -1){
                fos.write(bytes, 0, length);
            }
            bos.close();
            fos.close();
            bis.close();
            is.close();
        }
    
        public static void main(String[] args) throws IOException {
            String url="https://blog.csdn.net/qq_35387940/article/details/129611551";
            HtmlSaveUtil.saveHtml("D:\\blog\\129611551.html",url);
    
        }
    
    }

运行main方法， 效果：
