Question

我已经构建了核心java代码来读取excel数据并推入数据库。它工作正常。现在我想在excel表中添加一些验证检查。我无法做到这一点。考虑我有一些列是SettleDate，TradeDate，TradeID，IFStatus，IFVersion，IFDate，IFTime。我想在vlidation规则下面做。

定居不应该超过TradeDate。
TradID应为14 letteres。
IFStatus，IFVersion，IFDate，IFTime应为空白

以下是我的代码........

try {
    Class forName = Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
    Connection con = null;
    con = DriverManager.getConnection("jdbc:sybase:Tds:tkbgssvt1:4105", "kauai_rwu", "rwu_kauai");
    System.out.println("Database connected to Sybase..");
    con.setAutoCommit(false);
    PreparedStatement pstm = null;
    FileInputStream input = new FileInputStream(
            "C:\\Users\\suresnar\\Desktop\\Mizu_FGloss\\Kauai_IN_Table_test.xlsx");                
    XSSFWorkbook workbook = new XSSFWorkbook(input);
    XSSFSheet sheet = workbook.getSheetAt(0);
    Row row;
    for (int i = 1; i <= sheet.getLastRowNum(); i++) {
        row = (Row) sheet.getRow(i);

有人能帮帮我吗？你的帮助很大... 谢谢， Suresh N

我想有几种不同的方法可以做到这一点：

如果您真的拥有Excel文件并创建它。您可以创建自己的公式来“验证”您想要的单元格。
您可以为要验证的每种类型创建不同的类，每个“单元格”都有自己的类/验证
您可以手动创建验证并申请您要验证的每个字段（直接在java中，根据您从“字符串”中获取 excel文件）。
因为您（真的）应该将SQL查询更改为Hibernate，之后您可以使用hibernate验证器（在插入db之前）。

使用核心java验证Excel工作表
