Question

My problem is that I read from the db, numbers (BigDecimal) and I view them with DOT as decimal separator, but I would like to see them with COMMA. I used the following code:
@ NumberFormat (style = Style.NUMBER, pattern = “##,###,###.##”)
private BigDecimal number;

My application with the following architecture:
oracle db – hibernate – spring mvc

I need an automatic conversion without manually convert to string with DecimalFormat.

I solved this way:

@InitBinder
public void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception {  
    DecimalFormat df =new DecimalFormat();  
    DecimalFormatSymbols dfs = new DecimalFormatSymbols();  
    dfs.setDecimalSeparator(',');  
    df.setGroupingUsed(false);  
    df.setDecimalFormatSymbols(dfs);  
    df.setMaximumFractionDigits(32);  
    df.setMaximumIntegerDigits(32);  
    binder.registerCustomEditor(BigDecimal.class, new CustomNumberEditor(BigDecimal.class,df, true));
}
