In the case of Spring Data Rest then, while the solution posted by @r1ckr works, all that is required is to add one of the following dependencies depending on your Hibernate version:

    com.fasterxml.jackson.datatype
    jackson-datatype-hibernate4
    ${jackson.version}

or

    com.fasterxml.jackson.datatype
    jackson-datatype-hibernate5
    ${jackson.version}

Within Spring Data Rest there is a class:

org.springframework.data.rest.webmvc.json.Jackson2DatatypeHelper

which will auto-detect and register the Module on application start-up.

There is however an issue:
