5.2.2.3.4. Examples of Date and Number Formatting in the Application Code

If you need to format or parse values of BigDecimal, Integer, Long, Double, Boolean or Date types depending on the current user locale, use the DatatypeFormatter bean. For example:

@Inject
private DatatypeFormatter formatter;

void sample() {
    String dateStr = formatter.formatDate(dateField.getValue());
    // ...
}

Below are examples of using Datatype methods directly.

  • Date formatting example:

    @Inject
protected UserSessionSource userSessionSource;
@Inject
protected DatatypeRegistry datatypes;

void sample() {
    Date date;
    // ...
    String dateStr = datatypes.getNN(Date.class).format(date, userSessionSource.getLocale());
    // ...
}

  • Example of formatting numeric values with up to 5 decimal places in Web Client:

    com/sample/sales/web/messages_ru.properties 
    coordinateFormat = #,##0.00000
    @Inject
protected Messages messages;
@Inject
protected UserSessionSource userSessionSource;
@Inject
protected FormatStringsRegistry formatStringsRegistry;

void sample() {
    String coordinateFormat = messages.getMainMessage("coordinateFormat");
    FormatStrings formatStrings = formatStringsRegistry.getFormatStrings(userSessionSource.getLocale());
    NumberFormat format = new DecimalFormat(coordinateFormat, formatStrings.getFormatSymbols());
    String formattedValue = format.format(value);
    // ...
}
