public class ApplicationConversionService
extends FormattingConversionService

A specialization of FormattingConversionService configured by default with converters and formatters appropriate for most Spring Boot applications.

Designed for direct instantiation but also exposes the static addApplicationConverters(org.springframework.core.convert.converter.ConverterRegistry) and addApplicationFormatters(FormatterRegistry) utility methods for ad-hoc use against registry instance.

Add converters useful for most Spring Boot applications.

Parameters:

registry - the registry of converters to add to (must also be castable to ConversionService, e.g. being a ConfigurableConversionService)

Throws:

ClassCastException - if the given ConverterRegistry could not be cast to a ConversionService

addDelimitedStringConverters

public static void addDelimitedStringConverters(ConverterRegistry registry)

Add converters to support delimited strings.

Parameters:

registry - the registry of converters to add to (must also be castable to ConversionService, e.g. being a ConfigurableConversionService)

Throws:

ClassCastException - if the given ConverterRegistry could not be cast to a ConversionService
