Answer 1

去阿帕奇下载apache.org/poi
项目的源码：
import org.apache.poi.ss.usermodel.Row
import org.apache.poi.xssf.usermodel.XSSFCell
import org.apache.poi.xssf.usermodel.XSSFRow
import org.apache.poi.xssf.usermodel.XSSFSheet
import org.apache.poi.xssf.usermodel.XSSFWorkbook
/**

class TestGroovy {

void updateResourceDate(){
def filePath = "./assets/people.xlsx"

File file = new File(filePath)

FileInputStream is = new FileInputStream(file);

XSSFWorkbook workbook = new XSSFWorkbook(is);
workbook.setMissingCellPolicy(Row.CREATE_NULL_AS_BLANK);

//循环sheet
(0..<workbook.sheetIterator().collect {return it}.@size).each {s->
XSSFSheet sheet = workbook.getSheetAt(s);
int rows = sheet.physicalNumberOfRows;

//忽略第一行,标题行
(1..<rows).each{r->
XSSFRow row = sheet.getRow(r);
def cells = row.physicalNumberOfCells;

(0..<cells).each{c->
XSSFCell cell = row.getCell(c);

def name = "";

switch (c) {
case 0:
name = "A:"
break;
case 1:
name = "B:"
break
case 2:
name = "C:"
break
case 3:
name = "D:"
break
}
print name + " "+cell+ ", ";

}
println "";
}
}
}

static main(args) {
TestGroovy a = new TestGroovy();
a.updateResourceDate();
}
}
