  • 查看
    employee_data.jsp中的
    rs.getXXX（）
    。您没有遵循订单。对于
    select*from employee_details
    ，在调用
    rs.getXXX（）
    时，应使用
    resultset
    的正确方法。如果查看表格，您只有第9和第10个as日期，因此
    rs.getDate（8）
    不正确。仅对第9列和第11列使用
    rs.getDate（）
    ，即
    rs.getDate（9）
    和
    rs.getDate（11）
    

    out.println（“+rs.getString（7）+”）；/？？
out.println（“+rs.getString（10）+”）；
out.println（“+rs.getString（11）+”）；/？？？？

    • 

  • 不要使用
    select*
    。这是一种不好的做法。将来，如果您的
    employee\u details
    有更多列，则您必须更改代码以适应这些新列。使用
    从employee\u details
    中选择EmployeeID，Password
    • 

  • 使用
    rs.getXXX（index）
    中的索引时要小心。可能会出错。相反，您可以使用
    rs.getXXX（columnnameintbl）
    。例如，可以使用
    rs.getString（1）
    而不是
    rs.getString（“EmployeeID”）
    • 

    希望这能有所帮助！
