import java.io.FileNotFoundException;
import java.io.IOException;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.junit.Test;

public class POITest {
	@Test
	public void test() throws FileNotFoundException, IOException {
		//定义导入excel文件的路径
		String filePath = "D:\\区域导入测试数据.xls";
		//包装一个Excel文件对象
		HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(new File(filePath)));
		//读取Excel文件中的第一个sheet标签
		HSSFSheet hssfSheet = workbook.getSheetAt(0);
		//遍历标签页中所有的行
		for(Row row: hssfSheet) {
			//遍历标签行里的所有单元格
			for(Cell cell: row) {
				//输出单元格中的数据
				String val = cell.getStringCellValue();
				System.out.print(val);
			}
			System.out.println();
		}
	}
}
