如何将Apache POI函数传递给Groovy脚本中的Java比较程序类

@Grab('org.apache.poi:poi:4.1.2')
import org.apache.poi.ss.usermodel.*

public class ComparisonProgram {
    public static void compareExcelFiles(String file1, String file2) throws IOException {
        Workbook workbook1 = WorkbookFactory.create(new File(file1));
        Workbook workbook2 = WorkbookFactory.create(new File(file2));

        // 使用Apache POI函数进行Excel文件比较
        // ...

        workbook1.close();
        workbook2.close();
    }
}

def comparisonProgram = new ComparisonProgram()
comparisonProgram.compareExcelFiles("file1.xlsx", "file2.xlsx")
