1、在專案開發過程中需要將Excel檔案匯入到資料庫中，應用到jxl.jar 進行解析

2、如下

1. package test;
2. import java.io.File;
3. import java.io.IOException;
4. import java.io.UnsupportedEncodingException;
5. import javax.servlet.http.HttpServletResponse;
6. import jxl.Sheet;
7. import jxl.Workbook;
8. import jxl.WorkbookSettings;
9. import jxl.read.biff.BiffException;
10. import jxl.write.Label;
11. import jxl.write.WritableSheet;
12. import jxl.write.WritableWorkbook;
13. import jxl.write.WriteException;
14. publicclass JxlTest {
15. publicstaticvoid main(String[] args) {
16.         (new JxlTest()).excelRead();
17.     }
18. publicvoid excelRead(){
19.         File file = new File("d://cicc825.xls");
20. try {
21.             WorkbookSettings workbookSettings=new WorkbookSettings();
22.             workbookSettings.setEncoding("ISO-8859-1"); //關鍵程式碼，解決中文亂碼
23.             Workbook book= Workbook.getWorkbook(file,workbookSettings);
24. //Workbook book= Workbook.getWorkbook(file);
25.             Sheet sheet=book.getSheet(
    0); 
26. int row = sheet.getRows();
27. int column =sheet.getColumns();
28. for(int i=0;i<row;i++){
29. for(int j=0;j<column;j++){
30.                     System.out.println(sheet.getCell(j, i).getContents());
31.                 }
32.             }
33.         } catch (BiffException e) {
34.             e.printStackTrace();
35.         } catch (IOException e) {
36.             e.printStackTrace();
37.         }
38.     }
39. publicvoid excelWrite(HttpServletResponse response) {
40. long time = System.currentTimeMillis();// 用當前的系統時間作為預設表名
41.         String name = String.valueOf(time);
42.         name ="position";
43.         String pathName = name + ".xls";
44. try {
45.             pathName = new String(pathName.getBytes(), "ISO-8859-1");
46.         } catch (UnsupportedEncodingException e) {
47.             e.printStackTrace();
48.         }
49. // 獲取彈出儲存框的儲存路徑和表名
50.         response.setContentType("APPLICATION/OCTET-STREAM");
51.         response.setHeader("Content-Disposition", "attachment; filename=/"" + pathName + "/"");
52.         WritableWorkbook workbook;
53.         WorkbookSettings   workbookSettings=new   WorkbookSettings(); 
54.         workbookSettings.setEncoding("GB2312");
55. try {
56.             workbook = Workbook.createWorkbook(response.getOutputStream(),workbookSettings);
57.             WritableSheet ws = workbook.createSheet("sheet 1", 0);
58.             ws.setColumnView(0,22);
59.             Label cell = null;
60. for(int i=0;i<2;i++){
61.                 cell = new Label(0, i+1, "id");
62.                 ws.addCell(cell);
63.                 cell = new Label(1, i+1, "name");
64.                 ws.addCell(cell);
65.             }
66.             workbook.write();
67.             workbook.close();   // 一定要關閉, 否則沒有儲存Excel;
68.         } catch (IOException e) {
69.             e.printStackTrace();
70.         }catch (WriteException e) {
71.             e.printStackTrace();
72.         } 
73.     }
74. }

3、解析過程還是比較簡單的。
