apache POI之excel操作

Apache POI是Apache软件基金会的开放源码函式库，POI提供API给Java程序对Microsoft Office格式档案读和写的功能

1.下载开发包解压：

2.引入POI的依赖：

                   <dependency>

                            <groupId>org.apache.poi</groupId>

                            <artifactId>poi</artifactId>

                            <version>3.11</version>

                   </dependency>

3.POI使用：

@Test

         public void test1() throws FileNotFoundException, IOException{

                   String filePath = "C:\\Users\\zhaoqx\\Desktop\\资料\\区域导入测试数据.xls";

                   //包装一个Excel文件对象

                   HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(new File(filePath)));

                   //读取文件中第一个Sheet标签页

                   HSSFSheet hssfSheet = workbook.getSheetAt(0);

                   //遍历标签页中所有的行

                   for (Row row : hssfSheet) {

                            System.out.println();

                            for (Cell cell : row) {

                                     String value = cell.getStringCellValue();

                                     System.out.print(value + " ");

                            }

                   }

         }
