Java 解析excel批注

要解析Excel批注，可以利用Apache POI这个Java库。下面是一个简单的示例代码：

import java.io.FileInputStream;
import java.io.IOException;
import org.apache.poi.hssf.usermodel.HSSFComment;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;

public class ExcelCommentParser {
    public static void main(String[] args) throws IOException {
        FileInputStream fis = new FileInputStream("example.xls");
        HSSFWorkbook workbook = new HSSFWorkbook(fis);
        Sheet sheet = workbook.getSheetAt(0);

        for (Row row : sheet) {
            for (Cell cell : row) {
                HSSFComment comment = (HSSFComment) cell.getCellComment();
                if (comment != null) {
                    System.out.println("Comment for cell " + cell.getAddress() + ": " + comment.getString().getString());
                }
            }
        }

        workbook.close();
        fis.close();
    }
}

这个示例代码会打印出Excel中所有批注的内容。你需要将`example.xls`替换成你要解析的Excel文件名。
