How can I validate @RequestParam using javax validations annotation

Question

I have used javax validations for @RequestBody and it works. say

public void putData(@Valid @RequestBody DataDTO dataDTO)
{
   .....
}

class DataDTO
{
   @Digit(integer = 10, fraction = 3)
   private BigDecimal value;
}

But what if we do not have @RequestBody or DTO and just a single parameter. For example I have a following method in controller,

public String getCityWithTemprature(@RequestParam BigDecimal temptrature)
{
   ....
}

How I can validate it using @Digit of javax validations Or any other best way to do it

Thank you :)
