用java怎么将excel表格数据导入到mysql数据库中

Answer 1

参考下面方法：
import java.io.FileInputStream;­
import java.io.FileNotFoundException;­
import java.io.IOException;­
import org.apache.commons.logging.Log;­
import org.apache.commons.logging.LogFactory;­
import org.apache.poi.hssf.usermodel.HSSFCell;­
import org.apache.poi.hssf.usermodel.HSSFRow;­
import org.apache.poi.hssf.usermodel.HSSFSheet;­
import org.apache.poi.hssf.usermodel.HSSFWorkbook;­

public class TestExcel {­
//记录类的输出信息­
static Log log = LogFactory.getLog(TestExcel.class); ­
//获取Excel文档的路径­
public static String filePath = "D://excel.xls";­
public static void main(String[] args) {­
try {­
// 创建对Excel工作簿文件的引用­
HSSFWorkbook wookbook = new HSSFWorkbook(new FileInputStream(filePath));­
// 在Excel文档中，第一张工作表的缺省索引是0
// 其语句为：HSSFSheet sheet = workbook.getSheetAt(0);­
HSSFSheet sheet = wookbook.getSheet("Sheet1");­
//获取到Excel文件中的所有行数­
int rows = sheet.getPhysicalNumberOfRows();
//遍历行­
for (int i = 0; i < rows; i++) {­
// 读取左上端单元格­
HSSFRow row = sheet.getRow(i);­
// 行不为空­
if (row != null) {­
//获取到Excel文件中的所有的列­
int cells = row.getPhysicalNumberOfCells();­
String value = ""; ­
//遍历列­
for (int j = 0; j < cells; j++) {­
//获取到列的值­
HSSFCell cell = row.getCell(j);­
if (cell != null) {­
switch (cell.getCellType()) {­
case HSSFCell.CELL_TYPE_FORMULA:­
break;­
case HSSFCell.CELL_TYPE_NUMERIC:­
value += cell.getNumericCellValue() + ","; ­
break; ­
case HSSFCell.CELL_TYPE_STRING:­
value += cell.getStringCellValue() + ",";­
break;­
default:­
value += "0";­
break;­
}­
}
}­
// 将数据插入到mysql数据库中­
String[] val = value.split(",");­
TestEntity entity = new TestEntity();­
entity.setNum1(val[0]);­
entity.setNum2(val[1]);­
entity.setNum3(val[2]);­
entity.setNum4(val[3]);­
entity.setNum5(val[4]);­
entity.setNum6(val[5]);­
TestMethod method = new TestMethod();­
method.Add(entity);­
}­
}­
} catch (FileNotFoundException e) {­
e.printStackTrace();­
} catch (IOException e) {­
e.printStackTrace();­
}­
}­
}­

现有poi读取到java里，然后通过java操作数据库把读取的内容插入到数据库里。

Answer 3

不用java，直接复制excel到sql就可以
