Java操作excel

使用JexcelApi包 maven依赖

 

<dependency>
                        <groupId>net.sourceforge.jexcelapi</groupId>
			<artifactId>jxl</artifactId>
			<version>2.6.12</version>
</dependency>

 可以以文件形式读取，也可以读取流形式读取，比如读取HTTP上传的excel文件

 

	public void getExcel(HttpServletRequest request){
		final FileItem item = getFileItem(request);
		Workbook book = Workbook.getWorkbook(item.getInputStream());
		Sheet sheet = book.getSheet(0);
		int rows = sheet.getRows();
		int cols = sheet.getColumns();
		String errMsg = "errorline:";
		int errCount = 0;
		for (int i = 1; i < rows; i++) {
			for(int j=0;j<cols;j++)
				System.out.print(sheet.getCell(j,i).getContents);
			System.out.println()
		}
		book.close();
	}
	static FileItem getFileItem(HttpServletRequest request) throws FileUploadException {
		DiskFileItemFactory fac = new DiskFileItemFactory();
		ServletFileUpload upload = new ServletFileUpload(fac);
		upload.setHeaderEncoding("utf-8");
		List<FileItem> items = upload.parseRequest(request);
		for (FileItem item : items)
			if (!item.isFormField())
				return item;
		return null;
	}

 如果以读取本地文件的话

 

File file=new File("D:\\a.xls");
Workbook book=Workbook.getWorkbook(file);
