核心代码

html 是F12抓取的页面代码，需要替换中文文件目录

CellDTO[][] gen = HtmlUtils.gen(html);String key =null;List<CellDTO> data =null;TemplateEngine engine = TemplateUtil.createEngine(new TemplateConfig("templates", TemplateConfig.ResourceMode.CLASSPATH));Template template = engine.getTemplate("Controller.java.vm");for (int i = 0; i <gen.length ; i++) {CellDTO cell= gen[i][1];if (key == null) {key=cell.getNamePY();data =new ArrayList<>();}if(key.equals(cell.getNamePY() ) ){data.add( gen[i][2]);}else {CODE_WRITE(gen,i,data,template);key=cell.getNamePY();data =new ArrayList<>();data.add( gen[i][2]);}}CODE_WRITE(gen,gen.length,data,template);}public static void CODE_WRITE(CellDTO[][] gen, int i , List<CellDTO> data, Template template){String py= gen[i-1][1].getNamePY();String apiValue =gen[i-1][0].getNameZW()+" - "+gen[i-1][1].getNameZW();Map<String,Object> map = new HashMap<>();map.put("datas",data);map.put("requestMapping",py);String requestMappingUF=StrUtil.upperFirst(py);map.put("requestMappingUF",requestMappingUF );map.put("apiValue",apiValue);String fileName= requestMappingUF+"Controller.java";String result = template.render(map);String filePath="文件目录\\main\\java\\com\\binarywang\\demo\\wx\\mp\\controller\\"+fileName;FileUtil.writeUtf8String(result,new File(filePath));System.out.println(result);System.out.println("  ");}
