在 Java 中识别 Excel 中的删除线(strikethrough)可以使用多种方式,其中一种常见的方式是使用 Apache POI 库。下面我将详细介绍使用 Apache POI 来实现这个目标的步骤流程,包括 Maven 和 Gradle 的依赖坐标,并附上示例代码。
步骤流程:
添加 Maven 依赖或 Gradle 依赖:
Maven 依赖坐标:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>5.0.0</version>
</dependency>
Gradle 依赖坐标:
implementation 'org.apache.poi:poi:5.0.0'
读取 Excel 文件:
FileInputStream fis = new FileInputStream("path/to/your/excel/file.xlsx");
Workbook workbook = new XSSFWorkbook(fis); // For .xlsx files
// Alternatively, for .xls files
// Workbook workbook = new HSSFWorkbook(fis);
获取单元格样式并检查删除线:
Sheet sheet = workbook.getSheetAt(0); // Assuming you're working with the first sheet
Row row = sheet.getRow(rowNumber); // Replace with the desired row number
Cell cell = row.getCell(cellNumber); // Replace with the desired cell number
CellStyle cellStyle = cell.getCellStyle();
Font font = cellStyle.getFont();
boolean hasStrikethrough = font.getStrikeout();
根据 hasStrikethrough
判断是否有删除线:
if (hasStrikethrough) {
System.out.println("Cell has strikethrough.");
} else {
System.out.println("Cell does not have strikethrough.");
}
关闭资源:
workbook.close();
fis.close();
示例代码:
import org.apache.poi.ss.usermodel.*;
import java.io.FileInputStream;
import java.io.IOException;
public class ExcelStrikethroughChecker {
public static void main(String[] args) {
try {
FileInputStream fis = new FileInputStream("path/to/your/excel/file.xlsx");
Workbook workbook = new XSSFWorkbook(fis);
Sheet sheet = workbook.getSheetAt(0);
Row row = sheet.getRow(0);
Cell cell = row.getCell(0);
CellStyle cellStyle = cell.getCellStyle();
Font font = cellStyle.getFont();
boolean hasStrikethrough = font.getStrikeout();
if (hasStrikethrough) {
System.out.println("Cell has strikethrough.");
} else {
System.out.println("Cell does not have strikethrough.");
}
workbook.close();
fis.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
请确保替换示例代码中的文件路径、行号、列号等为实际值。以上就是使用 Apache POI 库来识别 Excel 中删除线的详细步骤流程。注意,这里只演示了基于字体样式的删除线判断,如果删除线是通过其他方式添加的(如单元格格式设置),则需要相应的判断逻辑。
