解析markdown生成的文件md

核心：读取文件
参考文章https://blog.csdn.net/w3045872817/article/details/78429742

这边稍微优化了下

 public String get()throws Exception{
        String html ="";
        FileReader fr = new FileReader("E:/test.md");
        BufferedReader br = new BufferedReader(fr);
        String str;
        while(null != (str=br.readLine())){
            str+="\n";
            html += str;
        }
        br.close();
        PegDownProcessor pdp = new PegDownProcessor(Integer.MAX_VALUE);
        html = pdp.markdownToHtml(html);
        return html;
    }
