Jackson json provider linkedHashSet deserialization

Question

We are using Spring rest template and jackson json provider to serialize/deserialize json. From my services i send a linkedHashSet back which gets converted to a HashSet on the client side when i receive it. Because of this I loose my insertion order of elements. Is this the default implementation of jackson json provider for Set ? Is there any other way, so it can deserialize to proper implementation? I feel it's gonna be tricky but inputs will be highly appreciated from you guys.

Thanks

You can specify the concrete class for Jackson to use with the @JsonDeserialize annotation. Just put:

@JsonDeserialize(as=LinkedHashSet.class)

On the property's setter.
