Question

I’m working with Spring 3.0.2 using Hibernate 3.2.1 and Oracle 10g as a back end. In an Oracle database table, there is a field whose data type is Date. This Date type field is mapped with java.util.Date in Hibernate (POJO) something like the following.

private Date discountStartDate;

While inserting or updating data into the Oracle table, I’m supplying a java.lang.String type date something like this 08/15/2012 15:08:13. There is no problem at all. Everything works well but since Oracle date data type (as far my knowledge) is always mapped with java.util.Date with Hibernate entity, I can’t use other Java APIs like Calendar and I have to use the deprecated constructor of the Date class to deal with Hibernate as follows.

Discount obj=new Discount();
date=new Date(request.getParameter("txtDiscountStartDate"));
obj.setDiscountStartDate(date);

Such deprecated functionality should be avoided. Is there a way to get around this deprecated Date(“StringDate”) constructor in Hibernate?

Answer 1

No, that’s wrong.

You should be parsing that String into a Date using DateFormat and SimpleDateFormat.

Here is an example.

Here’s another, since this seems difficult for you:

DateFormat formatter = new SimpleDateFormat("yyyy-MMM-dd");
formatter.setLenient(false);
String discountDateAsString = request.getParameter("txtDiscountStartDate");
Date discountDate = formatter.parse(discountDateAsString);
