rest - Return an array with a single element using Gson and HAL (Hypertext Application Language) -
i'm having problems using halarious (java library hal specification) , gson serialise list of links in _links section single element. array serialized object instead of being array single link.
example: i'm getting is:
{ "year": 2008, "_embedded": { "items": { "_links": { "self": { "href": "/first_item" } } } } } instead of:
{ "year": 2008, "_embedded": { "items": { "_links": { "self": [ { "href": "/first_item" } ] } } } } i solved same problem _embedded section can't solve links section.
thanks
i solved using workaround. dont' use @hallink surrogate ad hoc class contains hierarchy , instance named "_links".
so using list of custom href objects when has single link i'll receive expected self attribute list single element.
after hal documentation (http://stateless.co/hal_specification.html) says: "if you're unsure whether link should singular, assume multiple" , http://blog.stateless.co/post/13296666138/json-linking-with-hal "where relation may potentially have multiple links sharing same key value should array of link objects". in way won't break consumers having them deal either json array or object.
