要使用Java中的POI库读取Excel数据并进行校验,可以按照以下步骤进行:
1. 添加POI依赖库,可以在Maven中添加以下依赖:
```
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.1.2</version>
</dependency>
```
2. 使用POI读取Excel数据,示例代码如下:
```
FileInputStream inputStream = new FileInputStream(new File("文件路径"));
Workbook workbook = new XSSFWorkbook(inputStream);
Sheet sheet = workbook.getSheetAt(0);
Iterator<Row> rowIterator = sheet.iterator();
while (rowIterator.hasNext()) {
Row row = rowIterator.next();
// 读取单元格数据
Cell cell1 = row.getCell(0);
Cell cell2 = row.getCell(1);
// ...
// 进行校验,比如判断单元格是否为空等
if (cell1 == null || cell1.getCellType() == CellType.BLANK) {
// 处理空单元格
}
}
inputStream.close();
```
3. 根据实际需求进行数据校验,例如可以使用正则表达式判断数据格式是否正确。
以上是使用POI库读取Excel数据并进行校验的基本步骤,具体实现需要根据实际需求进行调整。
