透過Java解析Excel檔案
也是一個工作中遇到的情境,很多單位想讓內部人員利用Excel維護資料(因為維護上比較簡單方便),且想讓這份資料透過網頁呈現給一般網友閱讀,所以整體後端的流程應該是:
- 將維護的Excel透過網頁介面上傳
- 將上傳的Excel轉換成XML
- 網頁去讀取這份XML來呈現
透過以上的三個步驟,就可以完成客戶想要效果。
本範例展示的是讀取Excel的XLS格式(新版Excel為XLSX格式),並轉換成陣列的方法(寫入XML在前面的範例就有了),我們選用讀取Excel的Library是Apache POI,而檔內已經有以下的資料,其中Total是公式欄位,計算Price x Quantity:
ID | Name | Price | Quantity | Total |
100001 | 產品名稱1 | 10 | 5 | 50 |
100002 | 產品名稱2 | 20 | 10 | 200 |
100003 | 產品名稱3 | 30 | 15 | 450 |
以下是讀取的程式範例:
package CDIT.stanley; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStream; import java.util.ArrayList; import java.util.Iterator; import org.apache.poi.hssf.usermodel.HSSFCell; 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; public class excelToXMLFullSample { static ArrayList<ArrayList<String>> excelData = new ArrayList<ArrayList<String>>(); public static void main (String[] args) throws FileNotFoundException{ excelData.clear(); String xlsPath = "C:\\Projects\\Javas\\sample.xls"; InputStream inputStream = null; inputStream = new FileInputStream (xlsPath); POIFSFileSystem fileSystem = null; try { fileSystem = new POIFSFileSystem (inputStream); @SuppressWarnings("resource") HSSFWorkbook workBook = new HSSFWorkbook (fileSystem); HSSFSheet sheet = workBook.getSheetAt (0); Iterator<?> rows = sheet.rowIterator (); while (rows.hasNext ()){ HSSFRow row = (HSSFRow) rows.next(); Iterator<?> cells = row.cellIterator (); ArrayList<String> rowData = new ArrayList<String>(); while (cells.hasNext ()){ HSSFCell cell = (HSSFCell) cells.next(); switch (cell.getCellTypeEnum()){ case STRING :{ rowData.add(cell.getStringCellValue()); break; } case NUMERIC : { rowData.add((int)cell.getNumericCellValue() + ""); break; } case FORMULA :{ switch(cell.getCachedFormulaResultTypeEnum()) { case STRING: rowData.add(cell.getStringCellValue ()); break; case NUMERIC: rowData.add((int)cell.getNumericCellValue() + ""); break; default: rowData.add(""); break; } } default: rowData.add(""); break; } } excelData.add(rowData); } } catch(IOException e){ System.out.println("IOException " + e.getMessage()); System.out.println("轉換失敗,請檢查Excel檔案與格式是否正確"); } for(int i=0 ; i<excelData.size(); i++){ System.out.println("Excel Row "+ i +" Data : " + excelData.get(i)); } } }
程式會把Excel內的資料轉換為ArrayList,輸出內容如下:
Excel Row 0 Data : [Product ID, Product Name, Product Price, Quantity, Total] Excel Row 1 Data : [100001, 產品名稱1, 10, 5, 50, ] Excel Row 2 Data : [100002, 產品名稱2, 20, 10, 200, ] Excel Row 3 Data : [100003, 產品名稱3, 30, 15, 450, ]

No doubt, the days of bookmarking are over, but you can still use a browser-side bookmarking solution for those Pinterest boards and websites you like. Well, there is another bit of help if you need extra features and a rounded look.

For this reason it is thoughted to support robust fingerprint identification by the usage of special probability models, that understand if images are reliable enough, so they know when to apply shortcuts. With this aims we propose a new implementation of a robust fingerprint recognition algorithm for better localization of core points. These are detected by applying a circular, Sobel and Gaussian filters, followed by appropriate threshold techniques. Nevertheless, the filtered image is fed into a collection of robust features: invariant moments, center of gravity and https://pra-namorar.paineldemonstrativo.com.br/upload/files/2022/06/3VLEnYvLQw7XRKExmBVa_04_ac0770d739f403288218732b90a2f308_file.pdf

Yes, there is a whole lot of eye candy in this screensaver.
