import java.text.DateFormat;
import java.util.*;
import java.io.*;

    }
  }

  public static void main(String args[]) {
    Date time = new Date();
    DateFormat fullDateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG,DateFormat.LONG);
    System.out.println("The process start time:"+fullDateFormat.format(time));
    Jxlcreateexcel jxlexcle = new Jxlcreateexcel();
    try {
      jxlexcle.getExcelFile();
    }
    catch (Exception e) {

    System.out.println("The process end time:"+fullDateFormat.format(time1));
  }

}

这是我写的在linux上面导入excel的方式，windows里面也一样，只不过把生成文件的目录改一下，还有就是你需要下载一个lib，这个就是jxl.jar,（注：DBAccess是我写的一个连接数据库以及从数据库获取数据的一个类 ）另外还有一种方式就是poi，我也写了
