今天遇到一个poi导入的问题 参考别人的写了一个

package com.rshz.excel.derive;

public class Excels {
public static void main(String arg[]){
mx();
}

public static void mx(){
HSSFWorkbook workbook=null;
HSSFSheet sheet=null;

FileInputStream in=null;
try {
in=new FileInputStream("E:"+File.separator+"你好.xlsx");
workbook=new HSSFWorkbook(in);
sheet=workbook.getSheetAt(0);
Iterator<Row> it=sheet.rowIterator();
while(it.hasNext()){
HSSFRow row=(HSSFRow) it.next();
Iterator<Cell> tor=row.cellIterator();
while(tor.hasNext()){
HSSFCell cl=(HSSFCell)tor.next();
if(cl.getCellType()==Cell.CELL_TYPE_STRING){
System.out.print(cl.getStringCellValue()+"\t");
}else if(cl.getCellType()==Cell.CELL_TYPE_NUMERIC){
System.out.print(cl.getNumericCellValue()+"\t");
}else if(cl.getCellType()==Cell.CELL_TYPE_FORMULA){

}else if(cl.getCellType()==Cell.CELL_TYPE_BLANK){

}
}
System.out.println();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
}
}
