What should i use i if need a custom converter when using @RequestParam ???

Question

I if have a method signature as follows

public void deposit(@RequestParam("accountId") Integer accountId, 
                    @RequestParam("amount") BigDecimal amount) {...}

And because i have a locale specific decimal value which needs to be converted to a BigDecimal, is there some annotation which allows me to set up incoming data such as @Decimal("###.###,##") or something else ???

Answer 1

Spring 3 has @NumberFormat annotation:

public void deposit(@RequestParam("accountId") Integer accountId,  
    @RequestParam("amount") @NumberFormat(pattern = "###.###,##") BigDecimal amount) 
{...} 

You need <mvc:annotation-driven> to enable it.
