Spring Boot starters should reuse ConversionService

[manosbatsis]

Instead of "manually" trying to convert from String to a target type, the library should reuse converters and application settings via an @Autowired ConversionService

[perplexhub]

Which part do you mean? Custom value converter?

[manosbatsis]

Seems to me that, with the Spring Boot starter, RSQLVisitorBase does not use a ConversionService from the Spring context and thus does not utilize build-in or custom converters available.

As Object to Object conversion was removed from conversionService, I think we better not to remove it from the Spring one.

Custom converters can be add via RSQLJPASupport.addConverter().
