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
java解析excel文件。- 封装
json格式的数据。
实现思路
- 将国家提供的标准表格文件复制到
excel电子表格中。
- 解析excel表格，然后生成
json文件。 - 根据个人信息，从
JSON中查询对应的分数
代码实现
-
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：
-
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 0
Sheet 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();
