public String print(Date date, Locale locale)

Implements org.springframework.format.Printer.print.

Doc from org.springframework.format.Printer.print.

Print the object of type T for display.

Parameters

setFallbackPatternsback to summary
public void setFallbackPatterns(String... fallbackPatterns)

Set additional patterns to use as a fallback in case parsing fails for the configured pattern, ISO format, style, or style pattern.

Parameters
fallbackPatterns:String[]

the fallback parsing patterns

5.3.5

DateTimeFormat#fallbackPatterns()
setIsoback to summary
public void setIso(DateTimeFormat.ISO iso)

Set the ISO format to use to format date values.

Parameters
iso:DateTimeFormat.ISO

the ISO format

Since
3.2
setLenientback to summary
public void setLenient(boolean lenient)

Specify whether parsing is to be lenient. Default is false.

With lenient parsing, the parser may allow inputs that do not precisely match the format. With strict parsing, inputs must match the format exactly.

setPatternback to summary
public void setPattern(String pattern)

Set the pattern to use to format date values.

If not specified, DateFormat's default style will be used.

setSourceback to summary
public void setSource(Object source)

Set the source of the configuration for this DateFormatter — for example, an instance of the @DateTimeFormat annotation if such an annotation was used to configure this DateFormatter.

The supplied source object will only be used for descriptive purposes by invoking its toString() method — for example, when generating an exception message to provide further context.

Parameters
source:Object

the source of the configuration

Since
5.3.5
setStyleback to summary
public void setStyle(int style)

Set the DateFormat style to use to format date values.

If not specified, DateFormat's default style will be used.

DateFormat#DEFAULT, DateFormat#SHORT, DateFormat#MEDIUM, DateFormat#LONG, DateFormat#FULL
setStylePatternback to summary
public void setStylePattern(String stylePattern)

Set the two characters to use to format date values.

The first character is used for the date style; the second is used for the time style.

Supported characters:

  • 'S' = Small
  • 'M' = Medium
  • 'L' = Long
  • 'F' = Full
  • '-' = Omitted
This method mimics the styles supported by Joda-Time.
Parameters
stylePattern:String

two characters from the set {"S", "M", "L", "F", "-"}

Since
3.2
setTimeZoneback to summary
public void setTimeZone(TimeZone timeZone)

Set the TimeZone to normalize the date values into, if any.
