SortTranslator ignores snake-cased properties [DATAREST-1276]

[spring-projects-issues]

Édouard Hue opened DATAREST-1276 and commented

Given a @Document annotated class with the following attribute, and an according @RepositoryRestResource:

@Field
@JsonProperty("cooking_duration")
private Duration cookingDuration;

When issuing a GET request with ?sort=cooking_duration, the org.springframework.data.rest.webmvc.json.JacksonMappingAwareSortTranslator won't translate cooking_duration to cookingDuration and no sorting is performed.

When changing @JsonProperty("cooking_duration") to @JsonProperty("cooking-duration"), and doing a ?sort=cooking-duration request, JacksonMappingAwareSortTranslator properly resolves the property name.

It looks like org.springframework.data.rest.webmvc.json.JacksonMappingAwareSortTranslator.SortTranslator#SPLITTER is used to split the property name with _ and .. I can see the case for splitting on . for nested properties paths, but why would you split on underscores?

It seems it has been around for a while?
