一、strut2框架 利用其上传下载功能
二、xml解析技术 定制导入模板
三、jquery UI 制做前台 html
四、jquery
HSSF 与office03-07格式对应,版本低,兼容性好
XSSF 与xlsx格式对应apache
工做薄 excel
工做表 Sheet
行记录 row
单元格 cell框架
详见 http://poi.apache.org/overview.htmlmaven
如:spa
<dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.8</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.8</version> </dependency>
一、建立Excel工做簿
二、建立工做表sheet
三、建立第一行 title
四、建立一个文件
五、存盘excel
HSSFWorkbook
HSSFSheet
HSSFRow
HSSFCell
code
HSSFWorkbook book = new HSSFWorkbook(); HSSFSheet sheet = book.createSheet(); String[] columns = {"id","名字","性別"}; HSSFRow headeRow = sheet.createRow(0); for (int i = 0; i < columns.length; i++) { HSSFCell cell = headeRow.createCell(i); cell.setCellValue(columns[i]); } for (int i = 1; i < 11; i++) { HSSFRow nextRow = sheet.createRow(i); HSSFCell cell2 = nextRow.createCell(0); cell2.setCellValue(i); cell2 = nextRow.createCell(1); cell2.setCellValue("name" + i); cell2 = nextRow.createCell(2); cell2.setCellValue("男"); } FileOutputStream outputStream; try { outputStream = new FileOutputStream(new File(fileName)); book.write(outputStream); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); }
一、建立Excel,读取文件内容
二、默认读取第一个工做表xml
//建立Excel,读取文件内容 HSSFWorkbook workbook = new HSSFWorkbook(FileUtils.openInputStream(file)); //获取第一个工做表workbook.getSheet("Sheet0"); //HSSFSheet sheet = workbook.getSheet("Sheet0"); //读取默认第一个工做表sheet HSSFSheet sheet = workbook.getSheetAt(0); int firstRowNum = 0; //获取sheet中最后一行行号 int lastRowNum = sheet.getLastRowNum(); for (int i = firstRowNum; i <=lastRowNum; i++) { HSSFRow row = sheet.getRow(i); //获取当前行最后单元格列号 int lastCellNum = row.getLastCellNum(); for (int j = 0; j < lastCellNum; j++) { HSSFCell cell = row.getCell(j); String value = cell.getStringCellValue(); System.out.print(value + " "); } System.out.println(); }
