poi匯入記錄一下簡單操作

最基本的poi匯入老記不住 , 所以簡單記錄一下方便後期來看…

poi匯入匯出依賴 :

multipartfile file = multrequest.getfile("file"); //務必與前端input的mame一致

string filename = file.getoriginalfilename(); //獲取上傳的xls的name

workbook workbook=null;

inputstream in = file.getinputstream();

if(filename.endswith("xls") || filename.endswith("xls"))else

in.close();

try

}} catch (exception e)

匯入工具類:

public class myexcelutils 
sheet sheet = null;
row row = null;
cell cell = null;
list = new arraylist>();
//遍歷excel中所有的sheet
for (int i = 0; i < work.getnumberofsheets(); i++) 
//遍歷當前sheet中的所有行
for (int j = sheet.getfirstrownum(); j <= sheet.getlastrownum(); j++) 
//遍歷所有的列
listli = new arraylist();
for (int y = row.getfirstcellnum(); y < row.getlastcellnum(); y++) 
list.add(li);}}
in.close();
return list;
}/**

* * @param instr,filename
* * @return

*/public workbook getworkbook(inputstream instr, string filename) throws exception else if (excel2007u.equals(filetype)) else 
return wb;
}/**

break;
case cell.cell_type_boolean:
value = cell.getbooleancellvalue();
break;
case cell.cell_type_blank:
value = "";
break;
default:
break;
}return value;}}
