Excel文件的导入导出

前言：相信很多朋友在进行项目开发的时候都会面临着excel表格的导入导出功能，现在我给大家分享一下demo。

1.导入依赖，poi包支持的，不要出错了！！！

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>${poi.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>${poi.version}</version>
        </dependency>

poi的支持我得电脑的版本是：<poi.version>4.1.0</poi.version>

2.导入文件，话不多说直接上代码

  @Override
    public Boolean batchImportExl(InputStream in) {
        Boolean returnB = Boolean.TRUE;
        StringBuffer returnStr = new StringBuffer();
        try {
            Workbook wb = new XSSFWorkbook(in);
            Sheet sheet = wb.getSheetAt(0);
            int rowNo = sheet.getLastRowNum();
            Row row = null;
            Cell cell = null;
            List<TStaffInfo> addInfos = Lists.newArrayList();
            for (int i = 2; i <= rowNo; i++) {
                TStaffInfo staffInfo = new TStaffInfo();
                row = sheet.getRow(i);
                if (row.getCell(1)!=null){
                    cell = row.getCell(1);
                    cell.setCellType(CellType.STRING);
                    staffInfo.setName(cell.getStringCellValue());
                }
                row = sheet.getRow(i);
                if (row.getCell(2)!=null){
                    cell = row.getCell(2);
                    cell.setCellType(CellType.STRING);
                    staffInfo.setSex((cell.getStringCellValue().equals("男"))?1:2);
                }
                row = sheet.getRow(i);
                if (row.getCell(3)!=null){
                    cell = row.getCell(3);
                    cell.setCellType(CellType.STRING);
                    staffInfo.setNation(cell.getStringCellValue());
                }
                row = sheet.getRow(i);
                if (row.getCell(4)!=null){
                    cell = row.getCell(4);
                    cell.setCellType(CellType.STRING);
                    staffInfo.setPoliticalOutlook(cell.getStringCellValue());
                }
                row = sheet.getRow(i);
                if (Strings.isNotBlank(cell.getStringCellValue())){
                    cell = row.getCell(5);
                    cell.setCellType(CellType.STRING);
                    staffInfo.setTeam(cell.getStringCellValue());
                }
                row = sheet.getRow(i);
                if (row.getCell(6)!=null){
                    cell = row.getCell(6);
                    cell.setCellType(CellType.STRING);
                    staffInfo.setPost(cell.getStringCellValue());
                }
                row = sheet.getRow(i);
                if (row.getCell(7)!=null){
                    cell = row.getCell(7);
                    cell.setCellType(CellType.STRING);
                    staffInfo.setServerCommunity(cell.getStringCellValue());
                }
            }
            if (CollectionUtils.isNotEmpty(addInfos)){
                //将姓名一样的数据的角色信息合并
                for (int i=1;i<addInfos.size()-1;i++){
                    int j = 1;
                    TStaffInfo staffInfo = addInfos.get(i);
                    while (Optional.ofNullable(addInfos.get(i+j)).isPresent() && StringUtils.isEmpty(addInfos.get(i+j).getName())){
                        staffInfo.setServerCommunity(addInfos.get(i+j).getServerCommunity()+","+staffInfo.getServerCommunity());
                        j++;
                    }
                }
                addInfos = addInfos.stream().filter(e->StringUtils.isNotEmpty(e.getName())).collect(Collectors.toList());
                //添加数据
                saveBatch(addInfos);
            }
        }catch (IOException e){
            returnB = Boolean.FALSE;
            log.error(e.getMessage(), e);
        }
        return returnB;
    }

3.postman直接请求
