借助于apathe 的poi.jar，由于上传文件不支持.jar 所以请下载后将文件改为.jar，在应用程序中添加 poi.jar 包，并将需要读取的excel 文件放入根目录即可 本例使用 java 来读取 excel 的内容并展出出结果，代码如下： import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.text.DecimalFormat; import java.text.SimpleDateFormat; import java.util.ArrayList; import java.util.Arrays; import java.util.Date; import java.util.List; import org.apache.poi.hssf.usermodel.HSSFCell; import org.apache.poi.hssf.usermodel.HSSFDateUtil; import org.apache.poi.hssf.usermodel.HSSFRow; import org.apache.poi.hssf.usermodel.HSSFSheet; import org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.poifs.filesystem.POIFSFileSystem; public class ExcelOperate { public static void main(String[] args) throws Exception { File file = new File("ExcelDemo.xls"); String[][] result = getData(file, 1); int rowLength = result.length; for(int i=0;i result = new ArrayList(); int rowSize = 0; BufferedInputStream in = new BufferedInputStream(new FileInputStream( file)); // 打开 HSSFWorkbook POIFSFileSystem fs = new POIFSFileSystem(in); HSSFWorkbook wb = new HSSFWorkbook(fs); HSSFCell cell = null; for (int sheetIndex = 0; she...
