我是java的新手。 我正在使用apache poi将excel表中的数据插入到mysql中。 在后端我使用mysql创建了表。 我已导入所有jar文件。 我面临的错误是： 1.无法插入日期值。 2.当我删除日期列时，它只发送数据的地址而不是值。 有时它会告诉未找到的来源。 请帮我解决这个问题。

我无法对您的问题发表评论，因此我将根据我的理解尝试回答您在Excel中读取/写入DATE字段时遇到的问题。
我认为你错过了对Date字段的检查，excel在内部将日期存储为Numeric Contents，在显示时，它显示格式化的日期。此外，您还需要确保在您正在阅读的工作表中将列格式化为DATE列。
您需要使用以下代码片段将内容读取为DATE。
if（cell.getCellType（）== HSSFCell.CELL_TYPE_NUMERIC）{
// Excel stores the Date as a Numeric Contents. POI provides
// a Date utility to check
// if a particular cell is formatted as a date.
if (DateUtil.isCellDateFormatted(cell)) {
Date date = DateUtil.getJavaDate((double) cell
.getNumericCellValue());
SimpleDateFormat df = new SimpleDateFormat("dd/MM/yyyy HH:mm z");
System.out.println("The cell is a Date : " + df.format(date));
} else {
// treat the cell as 'double' number
System.out.println("The cell is a number : "
+ cell.getNumericCellValue());
}
}
有关完整的代码段，请参阅此link。请注意我已创作链接。

您可以使用jython代替POI吗？如果是这样，下面的代码将吐出一个CSV，然后可以使用[bulk loader]（http://dev.mysql.com/doc/refman/5.1/en/mysqlimport.html）通过命令将其加载到MySQL中代码如下：

要将其导入mysql，请使用java -cp jython.jar org.python.util.jython xlsx2csv [xlsx-file] [csv-output-file]; mysqlimport --local db1 [csv-output-file]。我希望这有帮助...
答案 2 :(得分：0)
Sql 将采用 yyyy-dd-mm 的日期格式。要以正确的格式插入数据，请尝试更改在 Excel 中插入日期值的单元格的格式，因为默认情况下它会将日期格式设为 dd/mm/yyyy。
要更改格式，请在每次在 Excel 中输入日期时按照说明进行操作。
说明：
右键单击单元格>单击格式单元格>从类别中查找并选择日期>在区域设置中选择选项“英语（英国）”>在类型中找到格式为yyyy-mm-dd的日期类型。
选择后，只需单击“确定”，然后您就可以将值插入数据库，然后它会发送您输入的日期而不是地址。
