Springboot Excel批量导入数据
POI处理Excel
org.apache.poi
poi-ooxml
3.9
net.sf.json-lib
json-lib
2.4
jdk15
下面是我们的数据库
前端使用Layui
成绩录入
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;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
@Component
public class ScoreExcelParse {
@Autowired
private 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;
@PostConstruct
public void init() {
scoreExcelParse = this;
scoreExcelParse.deptService=this.deptService;
}
public static List ExceltoScore(File userUploadFile){
List 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;
}
}
