最近在做体质测评的功能，需要依据《国民体质测定标准手册及标准》，根据用户的个人信息，从而计算出各个指标的的分；大致思路就是先将国家提供的标准，整理成JSON文件，然后用java代码调用JSON数据，从而计算出得分。

涉及技能点

1. java解析excel文件。
2. 封装json格式的数据。

实现思路

1. 将国家提供的标准表格文件复制到excel电子表格中。
   
2. 解析excel表格，然后生成json文件。
3. 根据个人信息，从JSON中查询对应的分数

代码实现

1. 直接将标准表格复制到excel中,复制完成之后简单的修改修改，不然解析起来麻烦，如下所示：

   

2. 解析excel的代码如下:

	/*** 20－29 岁成年人身高标准体重评分表（男）*/public static void adultsWithHeightWeightStandardScoreSheet() {String excelPath = System.getProperty("user.dir")+ "/src/main/excelFile/women-50-59height_and_weight_score.xlsx";try {//String encoding = "GBK";File excel = new File(excelPath);//判断文件是否存在if (excel.isFile() && excel.exists()) {//.是特殊字符，需要转义！！！！！String[] split = excel.getName().split("\\.");Workbook wb;//根据文件后缀（xls/xlsx）进行判断if ("xls".equals(split[1])) {//文件流对象FileInputStream fis = new FileInputStream(excel);wb = new HSSFWorkbook(fis);} else if ("xlsx".equals(split[1])) {wb = new XSSFWorkbook(excel);} else {System.out.println("文件类型错误!");return;}//开始解析//读取sheet 0Sheet sheet = wb.getSheetAt(0);//第一行int firstRowIndex = sheet.getFirstRowNum();//最后一行int lastRowIndex = sheet.getLastRowNum();System.out.println("一共有这么多行："+lastRowIndex);System.out.println("**************开始执行**************");List<ScoreExcelVO>  scoreExcelVOList = new ArrayList<>();JSONArray jsonArrayResult = new JSONArray();//遍历行for (int rIndex = firstRowIndex; rIndex < lastRowIndex; rIndex++) {Row row = sheet.getRow(rIndex);if (row != null) {//身高Cell cell_height = row.getCell(0);String height = cell_height.toString();//1分Cell cell_one_score1 = row.getCell(1);String one_score1 = cell_one_score1.toString();//3分Cell cell_three_score = row.getCell(2);String three_score = cell_three_score.toString();//5分Cell cell_five_score = row.getCell(3);String five_score = cell_five_score.toString();//3分Cell cell_three_score2 = row.getCell(4);String three_score2 = cell_three_score2.toString();//1分Cell cell_one_score2 = row.getCell(5);String one_score2 = cell_one_score2.toString();//将值放在实体类中ScoreExcelVO scoreExcelVO = new ScoreExcelVO();scoreExcelVO.setHeight(height);scoreExcelVO.setFirstOneScore(one_score1);scoreExcelVO.setFirstThreeScore(three_score);scoreExcelVO.setFiveScore(five_score);scoreExcelVO.setSecondOneScore(one_score2);scoreExcelVO.setSecondThreeScore(three_score2);scoreExcelVOList.add(scoreExcelVO);}}JSONArray array = new JSONArray();//将集合转换成JSON格式的数据//JSONArray scoreExcelVOArray = JSONArray.parseArray(JSON.toJSONString(scoreExcelVOList));scoreExcelVOList.forEach(scoreExcelVO->{JSONObject obj = new JSONObject();obj.put(scoreExcelVO.getHeight(),scoreExcelVO);array.add(obj);});String str = "";for(Object o : array){String old = o.toString().substring(1,o.toString().length()-1);str+=old+",";}//将最后一个逗号截取掉str = str.substring(0,str.length()-1);str = "{"+str+"}";System.out.println(str);} else {System.out.println("找不到指定的文件");}} catch (Exception e) {e.printStackTrace();}}

通过在main方法中调用，生成的json数据如下：

至此，解析json文件完成，后期分享一下，如何根据json数据，计算对应的分数。
