利用java反射处理excel数据导入示例

public class ExcelImportUtils{

	private static final Logger log = Logger.getLogger(ExcelImportUtils.class);

	public static <T> Object handlerExcel(String pathname,String classpath,
			int row,int cloNum) throws ClassNotFoundException,
			InstantiationException,IllegalAccessException{

			for (int j = row;j < rows;j++){
				// Cell[] cell = sheet.getRow(j);
				// for (int i = 0;i < cell.length;j++){
				// getCell(列，行)
