Web使用Apache poi对EXCEL操作（导入）

第一次尝试Web项目上传Excel数据进行导入

如果有哪里做的不对不好或者有更好的方法请联系我，谢谢

pom.xml中添加

        <!-- https://mvnrepository.com/artifact/org.apache.poi/poi -->
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
               <version>3.17</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml -->
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.17</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-schemas -->
        <dependency>

        </dependency>

只是做了一个学习测试，所以并没有插入数据库

Controller的代码

@RequestMapping("/upload")
	public String upload(@RequestParam("uploadFile") MultipartFile uploadFile) {
		if (MultipartFileWaf.checkSize(uploadFile)) {
			String excelType = MultipartFileWaf.checkIsExcel(uploadFile);
			try {
				InputStream fileInputStream = uploadFile.getInputStream();
				if ("xls".equals(excelType)) {
					HSSFWorkbook hwb = new HSSFWorkbook(fileInputStream);
					HSSFSheet hsheet = hwb.getSheetAt(0);
					medicalService.saveHSSFSheetMessage(hsheet);
					hwb.close();
				} else if ("xlsx".equals(excelType)) {
					XSSFWorkbook xwb = new XSSFWorkbook(fileInputStream);
					XSSFSheet xsheet = xwb.getSheetAt(0);
					medicalService.saveXSSFSheetMessage(xsheet);
					xwb.close();
				} else {
					System.out.println("上传失败");
				}
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		} else {
			System.out.println("上传失败");
		}
		return "success";
	}

检验文件大小的方法我就不发出来了，xls和xlsx的类不同，但是操作相同，一直在找这里有没有办法优化。

	private DecimalFormat df = new DecimalFormat("0");   
	@Override
	public int saveHSSFSheetMessage(HSSFSheet sheet) {
		// TODO Auto-generated method stub
		for(int i = 1;i <= sheet.getLastRowNum();i++) {
			Row row = sheet.getRow(i);
			Cell sid = row.getCell(0);
			Cell sname = row.getCell(1);
			Cell stature = row.getCell(2);
			Cell bp = row.getCell(3);
			Cell vision = row.getCell(4);
			String cellText = "";
			if("NUMERIC".equals(sid.getCellTypeEnum().toString())) {
				cellText = df.format(sid.getNumericCellValue()); 
			}
			else {
				cellText = sid.toString();
			}
			System.out.println(cellText+" "+sname+" "+stature+" "+bp+" "+vision+" ");
		}
		return 0;
	}

	@Override
	public int saveXSSFSheetMessage(XSSFSheet sheet) {
		// TODO Auto-generated method stub
		for(int i = 1;i <= sheet.getLastRowNum();i++) {
			Row row = sheet.getRow(i);
			Cell sid = row.getCell(0);
			Cell sname = row.getCell(1);
			Cell stature = row.getCell(2);
			Cell bp = row.getCell(3);
			Cell vision = row.getCell(4);
			String cellText = "";
			if("NUMERIC".equals(sid.getCellTypeEnum().toString())) {
				cellText = df.format(sid.getNumericCellValue()); 
			}
			else {
				cellText = sid.toString();
			}
			System.out.println(cellText+" "+sname+" "+stature+" "+bp+" "+vision+" ");
		}
		return 0;
	}
	

这里有个对excel数据类型的判定，POI3.15后就放弃getCellType进而使用getCellTypeEnum
