然后我们使用Mybatisplus对Bus_score自动生成一些类

主要的业务逻辑代码

package com.bs.bus.common;import com.bs.bus.entity.Score;
import com.bs.sys.common.excel.ExcelUtil;
import com.bs.sys.service.IDeptService;

public class ScoreExcelParse {@Autowiredprivate IDeptService deptService;//Autowired注解,spring不推荐使用静态方法,在非controller中使用的话需要在类加载之前初始化autowired服务，再进行使用public static ScoreExcelParse scoreExcelParse;@PostConstructpublic void init() {scoreExcelParse = this;scoreExcelParse.deptService=this.deptService;}public static List<Score> ExceltoScore(File userUploadFile){List<Score> list=new ArrayList<>();Score score=null;try {POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream(userUploadFile));HSSFWorkbook wb = new HSSFWorkbook(fs);//获取第一个sheet页HSSFSheet sheet = wb.getSheetAt(0);if(sheet!=null){for(int rowNum =1;rowNum<=sheet.getLastRowNum();rowNum++){HSSFRow row = sheet.getRow(rowNum);if(row==null){continue;}score=new Score();//将单元格里每行数据存入ScoreVo对象中score.setDeptname(ExcelUtil.formatCell(row.getCell(0)).split("\\.")[0]);score.setTestname(ExcelUtil.formatCell(row.getCell(1)));score.setUserid(Integer.parseInt(ExcelUtil.formatCell(row.getCell(2)).split("\\.")[0]));score.setUsername(ExcelUtil.formatCell(row.getCell(3)).split("\\.")[0]);score.setChinesescore(Integer.parseInt(ExcelUtil.formatCell(row.getCell(4)).split("\\.")[0]));score.setMathscore(Integer.parseInt(ExcelUtil.formatCell(row.getCell(5)).split("\\.")[0]));score.setEnglishscore(Integer.parseInt(ExcelUtil.formatCell(row.getCell(6)).split("\\.")[0]));score.setTeacherwords(ExcelUtil.formatCell(row.getCell(7)));score.setTotlescore(score.getChinesescore()+score.getEnglishscore()+score.getMathscore());score.setTestid(Md5Util.generateHash(score.getTestname()).substring(0,6));score.setDeptid(scoreExcelParse.deptService.getDeptByName(score.getDeptname()).getId());list.add(score);}}}  catch (IOException e) {e.printStackTrace();}return list;}
}
