Apache POI 是用Java编写的免费开源的跨平台的 Java API,Apache POI提供API给Java程式对Microsoft Office格式档案读和写的功能。
Apache POI 是创建和维护操作各种符合Office Open XML(OOXML)标准和微软的OLE 2复合文档格式(OLE2)的Java API。用它可以使用Java读取和创建,修改MS Excel文件.而且,还可以使用Java读取和创建MS Word和MSPowerPoint文件。Apache POI 提供Java操作Excel解决方案(适用于Excel97-2008)。
如果处理.xlsx、docx、pptx的话可以试试Docx4j 。
Docx4j is a Java library for creating and manipulating Microsoft Open XML (Word docx, Powerpoint pptx, and Excel xlsx) files.

Busy Developers' Guide to HSSF and XSSF Features
版本:poi-3.8-20120326.jar
1、生成Workbook
- //生成Workbook
- HSSFWorkbook wb = new HSSFWorkbook();
- //添加Worksheet(不添加sheet时生成的xls文件打开时会报错)
- @SuppressWarnings("unused")
- Sheet sheet1 = wb.createSheet();
- @SuppressWarnings("unused")
- Sheet sheet2 = wb.createSheet();
- @SuppressWarnings("unused")
- Sheet sheet3 = wb.createSheet("new sheet");
- @SuppressWarnings("unused")
- Sheet sheet4 = wb.createSheet("rensanning");
- //保存为Excel文件
- FileOutputStream out = null;
- try {
- out = new FileOutputStream("c:\text.xls");
- wb.write(out);
- } catch (IOException e) {
- System.out.println(e.toString());
- } finally {
- try {
- out.close();
- } catch (IOException e) {
- System.out.println(e.toString());
- }
- }
2、生成Workbook OOXML形式(.xlsx)
- //生成Workbook
- XSSFWorkbook wb = new XSSFWorkbook();
- //......
3、打开Workbook
- //方法一:使用WorkbookFactory
- FileInputStream in = null;
- Workbook wb = null;
- try {
- in = new FileInputStream(TEST_WORKBOOK_NAME);
- wb = WorkbookFactory.create(in);
- } catch (IOException e) {
- System.out.println(e.toString());
- } catch (InvalidFormatException e) {
- System.out.println(e.toString());
- } finally {
- try {
- in.close();
- } catch (IOException e) {
- System.out.println(e.toString());
- }
- }
- System.out.println("====================Workbook====================");
- System.out.println("Number of Sheets:" + wb.getNumberOfSheets());
- System.out.println("Sheet3's name:" + wb.getSheetName(3));
- System.out.println();
- //方法二:使用POIFSFileSystem
- try {
- in = new FileInputStream(TEST_WORKBOOK_NAME);
- POIFSFileSystem fs = new POIFSFileSystem(in);
- wb = new HSSFWorkbook(fs);
- } catch (IOException e) {
- System.out.println(e.toString());
- } finally {
- try {
- in.close();
- } catch (IOException e) {
- System.out.println(e.toString());
- }
- }
- System.out.println("====================Workbook====================");
- System.out.println("Number of Sheets:" + wb.getNumberOfSheets());
- System.out.println("Sheet3's name:" + wb.getSheetName(3));
- System.out.println();
4、打开加密的Workbook(读加密)
- FileInputStream input = new FileInputStream(TEST_WORKBOOK_NAME_ENCRYPTED);
- BufferedInputStream binput = new BufferedInputStream(input);
- POIFSFileSystem poifs = new POIFSFileSystem(binput);
- Biff8EncryptionKey.setCurrentUserPassword(TEST_WORKBOOK_PASSWORD);
- HSSFWorkbook wb = new HSSFWorkbook(poifs);
- System.out.println("====================EncryptedWorkbook====================");
- System.out.println("Number of Sheets:" + wb.getNumberOfSheets());
- System.out.println("Sheet0's name:" + wb.getSheetName(0));
- System.out.println();
5、追加Sheet
- Sheet sheet = wb.createSheet("append sheet");
6、复制Sheet
- wb.cloneSheet(1);
7、修改Sheet名称
- wb.setSheetName(i, "SheetName new");
8、删除Sheet
- wb.removeSheetAt(1);
9、设置下部Sheet名的Tab的第一个可见Tab
- //设置下部Sheet名的Tab的第一个可见Tab(以左的Sheet看不见)
- wb.setFirstVisibleTab(2);
10、调整Sheet顺序
- wb.setSheetOrder("SheetName3", 1);
- wb.setSheetOrder(wb.getSheetName(4), 0);
11、设置当前Sheet
t.setActiveSheet();
- //设置当前Sheet
- wb.setActiveSheet(wb.getNumberOfSheets() - 1);
- //(Excel的当前Sheet被设置,需要结合setSelected使用,不然下部Sheet名的Tab还是默认为第一个)
- //(需要选择多个Sheet的话,每个Sheet调用setSelected(true)即可)
- wb.getSheetAt(wb.getNumberOfSheets() - 1).setSelected(true);
12、固定窗口
- wb.getSheet("SheetName4").createFreezePane(2, 2);
13、分割窗口
- wb.getSheet("SheetName5").createSplitPane(2000, 2000, 0, 0, HSSFSheet.PANE_LOWER_LEFT);
14、Sheet缩放
- //setZoom(int numerator, int denominator)
- //"numerator"÷"denominator" 例如: 3÷1=3 那就是设置为300%
- //扩大(200%)
- wb.getSheet("sheetname1").setZoom(2, 1);
- //缩小(50%)

19、移动行
- //******移动行只移动内容,不牵扯行的删除和插入
- //移动行(把第1行和第2行移到第5行之后)
- wb.getSheet("sheetname5").shiftRows(0, 1, 5);
- //移动行(把第3行和第4行往上移动1行)
- wb.getSheet("sheetname5").shiftRows(2, 3, -1);
20、修改行高
- //设置默认行高
- wb.getSheet("sheetname6").setDefaultRowHeight((short)100);

- jpeg.close();
- HSSFCreationHelper helper = (HSSFCreationHelper) wb.getCreationHelper();
- HSSFPatriarch patriarch = ((HSSFSheet)wb.getSheet("sheetname15")).createDrawingPatriarch();
- HSSFClientAnchor clientAnchor = helper.createClientAnchor();
- clientAnchor.setCol1(3);
- clientAnchor.setRow1(2);
- HSSFPicture picture = patriarch.createPicture(clientAnchor, pictureIndex);
- picture.resize();
40、设置可输入List
- CellRangeAddressList addressList = new CellRangeAddressList(
- 0,
- 0,
- 0,
- 0);
- final String[] DATA_LIST = new String[] {
- "10",
- "20",
- "30",
- };
- DVConstraint dvConstraint =
- DVConstraint.createExplicitListConstraint(DATA_LIST);
- HSSFDataValidation dataValidation = new HSSFDataValidation(addressList, dvConstraint);
- dataValidation.setSuppressDropDownArrow(false);
- wb.getSheet("sheetname16").addValidationData(dataValidation);
41、设置输入提示信息
- CellRangeAddressList addressList = new CellRangeAddressList(
- 0,
- 0,
- 0,
- 0);
- final String[] DATA_LIST = new String[] {
- "10",
- "20",
- "30",
- };
- DVConstraint dvConstraint = DVConstraint.createExplicitListConstraint(DATA_LIST);
- HSSFDataValidation dataValidation =
- new HSSFDataValidation(addressList, dvConstraint);
- dataValidation.setSuppressDropDownArrow(false);
- dataValidation.createPromptBox("输入提示", "请从下拉列表中选择!");
- dataValidation.setShowPromptBox(true);
- wb.getSheet("sheetname17").addValidationData(dataValidation);
