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.
