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());
 }
}

    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();

//......

//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();

//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)

System.out.println("Number of Sheets:" + wb.getNumberOfSheets());
System.out.println("Sheet0's name:" + wb.getSheetName(0));
System.out.println();

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);

wb.setSheetOrder(wb.getSheetName(4), 0);

wb.setSheetOrder("SheetName3", 1);
wb.setSheetOrder(wb.getSheetName(4), 0);

11、设置当前Sheet

 

//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);

//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）

}
DataFormat format = wb.createDataFormat();

CellStyle[] styles = new CellStyle[2];
for (int i = 0; i < styles.length; i++) {
 styles[i] = wb.createCellStyle();
}
styles[0].setDataFormat(format.getFormat("0.0"));
styles[1].setDataFormat(format.getFormat("#,##0.000"));

Cell[] cells = new Cell[2];
for (int i = 0; i < cells.length; i++) {
 cells[i] = rows[i].createCell(1);
 cells[i].setCellValue(1111.25);

 cells[i].setCellStyle(styles[i]);
}

Row[] rows = new Row[2];
for (int i = 0; i < rows.length; i++) {
