Best practice to represent Money (value + currency) in Grails

Question

I'm not much familiar to Java Currency type, and how it being used in Grails. Though, I'm yet to use it, I saw a tag <g:currencySelect> to use in the views. So, how do I represent it in the domain class.

class Money {
BigDecimal value
Currency currency
....
}

or is there a better sol, which compares diff money objects, format according to the locale ( ',' in EU for separator etc)

thanks in advance. Babu.

Answer 1

You should use BigDecimal. Groovy and Grails has excellent native support for it as a datatype on GORM domain classes as well. For reasoning behind using it, see here
