org.springframework.format.annotation
Annotation Type NumberFormat


@Target(value={METHOD,FIELD,PARAMETER})
@Retention(value=RUNTIME)
public @interface NumberFormat

Declares that a field should be formatted as a number. Supports formatting by style or custom pattern string. Can be applied to any JDK java.lang.Number type.

For style-based formatting, set the style() attribute to be the desired NumberFormat.Style. For custom formatting, set the pattern() attribute to be the number pattern, such as #,###.##.

Each attribute is mutually exclusive, so only set one attribute per annotation instance (the one most convenient one for your formatting needs). When the pattern attribute is specified, it takes precedence over the style attribute. When no annotation attributes are specified, the default format applied is style-based with a style of NumberFormat.Style.NUMBER.
