*******************************************
郁闷的是，image.jpg是个啥文件，我根本没有调用啊，报错可能因为这个 包
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
找不到，可是我已经把poi-3.6的jar包放到librarises里了
代码如下：
