User input money value in grails

Question

I need to get a money value from the user, but the user can type the number in different formats:

1.234.234,78
1234566,26 
123,123,132.12 

I don't know how to treat the variable.

I have to transform that value in Double type but if the user give me a value with "," the program generate an exception, how can I handle this?

Answer 1

If you want to handle money then I recommend you a great grails plugin with many feature for currencies handling and conversions etc.

Have a look at Currency plugin.

Answer 2

In your domain static constraints use matches with the regular expression that handles currency format.

Then using java.text.NumberFormat allows you to format double regardless of having comma in the input.
