Apache POI读取Excel

1、pom.xml配置文件

 <!-- 配置Apache POI -->
         <dependency>
             <groupId>org.apache.poi</groupId>
             <artifactId>poi</artifactId>
             <version>4.1.0</version>
         </dependency>
         <dependency>
             <groupId>org.apache.poi</groupId>
             <artifactId>poi-ooxml</artifactId>
             <version>4.1.0</version>
         </dependency>
         <dependency>
             <groupId>org.apache.poi</groupId>
             <artifactId>poi-ooxml-schemas</artifactId>
             <version>4.1.0</version>
         </dependency>

2、读取Excel的Java代码

 @Test
     public void readExcelTest() throws IOException {
         File xlsFile = new File("E:\\book.xlsx");
         // 获得工作簿
         XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(xlsFile));
         // 获得sheet
         XSSFSheet sheet = wb.getSheetAt(0);
         int rows = sheet.getPhysicalNumberOfRows();
         String split = "**********";
         for (int i = 0; i < rows; i++) {
             // 获取第i行
             XSSFRow row = sheet.getRow(i);
             // 列数
             short nums = row.getLastCellNum();
             for (int j = 0; j < nums; j++) {
                 Cell cell = row.getCell(j);
                 System.out.print(cell + split);
             }
             System.out.println();
         }
     }

3、Excel文件和测试结果

以上只是java读取Excel应用演示，代码中没有对对象的非空判定，需要的童鞋可自行加上判定，使代码更健壮。
