Springboot 之 使用POI读取解析Excel文件
1、引入依赖jar包。
在pom.xml中引入两个依赖的包即可:
<dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>RELEASE</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>RELEASE</version> </dependency>
2、读取xxx.xlsx
@GetMapping(value = "/impPriceRecord") public InvokeResult impPriceRecord() throws Exception { try { List<AmoycarClue> infos = new ArrayList<AmoycarClue>(); InputStream is = new FileInputStream("D:/xxx.xlsx"); XSSFWorkbook xssfWorkbook = new XSSFWorkbook(is); XSSFSheet xssfSheet = xssfWorkbook.getSheetAt(0); XSSFRow titleCell = xssfSheet.getRow(0); for (int i = 1; i <= xssfSheet.getLastRowNum(); i++) { XSSFRow xssfRow = xssfSheet.getRow(i); int minCell = xssfRow.getFirstCellNum(); int maxCell = xssfRow.getLastCellNum(); XSSFCell bidCode = xssfRow.getCell(0); XSSFCell owerName = xssfRow.getCell(1); XSSFCell ownersex = xssfRow.getCell(2); XSSFCell owerMobile = xssfRow.getCell(3); XSSFCell basePrice = xssfRow.getCell(4); XSSFCell bidType = xssfRow.getCell(5); XSSFCell bidDealerId = xssfRow.getCell(6); XSSFCell bidDealerName = xssfRow.getCell(7); XSSFCell bidName = xssfRow.getCell(8); XSSFCell bidMobile = xssfRow.getCell(9); XSSFCell carNumber = xssfRow.getCell(10); XSSFCell autoNumber = xssfRow.getCell(11); XSSFCell carUnifiedNumber = xssfRow.getCell(12); XSSFCell curBid = xssfRow.getCell(13); XSSFCell bidStatus = xssfRow.getCell(14); XSSFCell maxBid = xssfRow.getCell(15); XSSFCell priceGap = xssfRow.getCell(16); XSSFCell bidCreateTime = xssfRow.getCell(17); XSSFCell expectPrice = xssfRow.getCell(18); XSSFCell roundStatus = xssfRow.getCell(19); AmoycarClue model = new AmoycarClue(); model.setBidCode(getValue(bidCode)); model.setBizoppCode(""); model.setOriginalCode(""); model.setWorkNo(""); model.setOwnerName(getValue(owerName) + ""); model.setOwnerSex(Double.valueOf(getValue(ownersex)).intValue()); model.setOwnerMobile(getValue(owerMobile)); model.setBasePrice(Double.valueOf(getValue(basePrice))); model.setBidName(getValue(bidName)); model.setBidMobile(getValue(bidMobile)); model.setBidType(Double.valueOf(getValue(bidType)).intValue()); model.setCarCode(code); model.setMaxBid(Double.valueOf(getValue(maxBid))); model.setCurBid(Double.valueOf(getValue(curBid))); model.setPriceGap((Double.valueOf(getValue(priceGap)))); model.setBidStatus(Double.valueOf(getValue(bidStatus)).intValue()); SimpleDateFormat pat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); if (bidCreateTime!= null) { try { String sDate=getValue(bidCreateTime); java.util.Date uDate = pat.parse(sDate); model.setBidCreatetime(uDate); } catch (ParseException ex) { ex.printStackTrace(); } } model.setRoundStatus(Double.valueOf(getValue(roundStatus)).intValue()); model.setExpectPrice(Double.parseDouble(getValue(expectPrice))); model.setBidDealerId(getValue(bidDealerId)); model.setBidDealerName(getValue(bidDealerName)); try { auctionClient.syncAmoycarClue(model); Thread.sleep(1000); } catch (Exception ex) { ex.printStackTrace(); return InvokeResult.failure(500, "impPriceRecord:插入错误BidCode:{" + model.getBidCode() +"}"+ ex.getMessage()); } } return InvokeResult.success(true); } catch (Exception e) { return InvokeResult.failure(500,"impPriceRecord:历史数据导入错误"+e.getMessage()); } }
3、格式方法
private String getValue(XSSFCell xssfRow) { if (xssfRow != null) { // if (xssfRow != null) { // xssfRow.setCellType(xssfRow.CELL_TYPE_STRING); // } if (xssfRow.getCellType() == xssfRow.CELL_TYPE_BOOLEAN) { return String.valueOf(xssfRow.getBooleanCellValue()); } else if (xssfRow.getCellType() == xssfRow.CELL_TYPE_NUMERIC) { String result = ""; if (xssfRow.getCellStyle().getDataFormat() == 22) { // 处理自定义日期格式:m月d日(通过判断单元格的格式id解决,id的值是58) SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); double value = xssfRow.getNumericCellValue(); Date date = org.apache.poi.ss.usermodel.DateUtil.getJavaDate(value); result = sdf.format(date); } else { double value = xssfRow.getNumericCellValue(); CellStyle style = xssfRow.getCellStyle(); DecimalFormat format = new DecimalFormat(); String temp = style.getDataFormatString(); // 单元格设置成常规 if (temp.equals("General")) { format.applyPattern("#"); } result = format.format(value); } return result; } else { return String.valueOf(xssfRow.getStringCellValue()); } } else return "0"; }
