读取excel表格的内容并输出打印

1、这里用到的是xxx.xlsx的excel表,如果用.xls的旧版excel表可能会报错,需要自己调整代码

(简单的测试,取出内容根据业务自行处理)

    public static void main(String[] args) throws Exception {

        File file = new File("D:\\test001\\qhData.xlsx");

        FileInputStream inputStream = new FileInputStream(file);
        XSSFWorkbook wb = new XSSFWorkbook(inputStream);
        XSSFSheet sheet = wb.getSheetAt(0);

        //读取excel的第一行
        XSSFRow row1 = sheet.getRow(0);
        for(int i = 0; i < row1.getLastCellNum(); i++){
            //循环打印(此行)的每一列内容
            System.out.println(row1.getCell(i)); //订单编号, ORDER_NO, LOWER(B1)

        }
}

 

 

 

 

2、优化升级版,传入excel文件的地址,取出里面每行,每列的数据

//读取解析EXCEL
    private void readExcelData(String excelPatah) {
        // 读取解析EXCEL
        InputStream inputstream;
        try {
            inputstream = new FileInputStream(excelPatah);
            Workbook book = null;
            if (!(inputstream.markSupported())) {
                inputstream = new PushbackInputStream(inputstream, 8);
            }
            if (POIFSFileSystem.hasPOIFSHeader(inputstream)) {
                book = new HSSFWorkbook(inputstream);
            } else if (POIXMLDocument.hasOOXMLHeader(inputstream)) {
                book = new XSSFWorkbook(OPCPackage.open(inputstream));
            }
            
            // 获取sheet 页数据
            Sheet sheet = book.getSheetAt(0);
            
            //读取excel的第一行
//            Row row1 = sheet.getRow(0);
            
            // 获取行数
            int rowCount = sheet.getPhysicalNumberOfRows();
            
            for(int i = 0; i < rowCount; i++) {
                //循环每一行===========================
                Row row = sheet.getRow(i);
                
                if(row != null) {
                    
                    String sql = row.getCell(0).toString(); //第一行:sql语句
                    String versions = row.getCell(1).toString(); //第二行:版本号
                    String remark = row.getCell(2).toString(); //第三行:备注
                    
                    
                    
                    //第一行的每一列数据打印
//                    for(int j = 0; j < row1.getLastCellNum(); j++){
//                        //循环打印(此行)的每一列内容
//                        System.out.println(row1.getCell(j)); 
//                        
//
//                        int r = systemService.executeSql(""); //执行sql语句
//                    }
                }
                
            }
            
            
            
            
            
            
            
            
            
         // 移动文件
//            Files.move(sourcePath, destPath, StandardCopyOption.REPLACE_EXISTING);
//            System.out.println("file move success");
            
            inputstream.close();//关闭流
            
            
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        
        
    }
