Apache POI读取Excel

1、pom.xml配置文件

 1 <!-- 配置Apache POI -->
 2         <dependency>
 3             <groupId>org.apache.poi</groupId>
 4             <artifactId>poi</artifactId>
 5             <version>4.1.0</version>
 6         </dependency>
 7         <dependency>
 8             <groupId>org.apache.poi</groupId>
 9             <artifactId>poi-ooxml</artifactId>
10             <version>4.1.0</version>
11         </dependency>
12         <dependency>
13             <groupId>org.apache.poi</groupId>
14             <artifactId>poi-ooxml-schemas</artifactId>
15             <version>4.1.0</version>
16         </dependency>

2、读取Excel的Java代码

 1 @Test
 2     public void readExcelTest() throws IOException {
 3         File xlsFile = new File("E:\book.xlsx");
 4         // 获得工作簿
 5         XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(xlsFile));
 6         // 获得sheet
 7         XSSFSheet sheet = wb.getSheetAt(0);
 8         int rows = sheet.getPhysicalNumberOfRows();
 9         String split = "**********";
10         for (int i = 0; i < rows; i++) {
11             // 获取第i行
12             XSSFRow row = sheet.getRow(i);
13             // 列数
14             short nums = row.getLastCellNum();
15             for (int j = 0; j < nums; j++) {
16                 Cell cell = row.getCell(j);
17                 System.out.print(cell + split);
18             }
19             System.out.println();
20         }
21     }

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。
