Spring formatting with Formatting from String to String and spring:eval does not work [SPR-11215]

[spring-projects-issues]

Janning Vygen opened SPR-11215 and commented

Image I have an IBAN saved as a String and a @IBANFormat to trigger formatting. When I render the IBAN with spring:eval it does not work.

ExpressionUtils does not call ConversionService if both types are the same and lacking formatting the value.

Line 66 in ExpressionUtils:
{{
public static <T> T convertTypedValue(EvaluationContext context, TypedValue typedValue, Class<T> targetType) {
Object value = typedValue.getValue();
if ((targetType == null) || (value != null && ClassUtils.isAssignableValue(targetType, value))) {
return (T) value;
}
if (context != null) {
return (T) context.getTypeConverter().convertValue(value, typedValue.getTypeDescriptor(), TypeDescriptor.valueOf(targetType));
}
throw new EvaluationException("Cannot convert value '" + value + "' to type '" + targetType.getName() + "'");
}

}}

The first "if" statement is triggered because both values are Strings. No conversion and no formatting takes place.
