Constructor Details

DefaultConversionService

public DefaultConversionService()

Create a new DefaultConversionService with the set of default converters.

Method Details

getSharedInstance

public static ConversionService getSharedInstance()

Return a shared default ConversionService instance, lazily building it once needed.

NOTE: We highly recommend constructing individual ConversionService instances for customization purposes. This accessor is only meant as a fallback for code paths which need simple type coercion but cannot access a longer-lived ConversionService instance any other way.

Returns:

the shared ConversionService instance (never null)
