How to remove the "_embedded" property in Spring HATEOAS

Question

I'm using Spring Boot and HATEOAS to build a REST API and when my API returns a collection, it is wrapped inside a "_embedded" property, like so:

{    "_links":{       "self":{          "href":"http://localhost:8080/technologies"       }    },    "_embedded":{       "technologies":[          {             "id":1,             "description":"A",             "_links":{                "self":{                   "href":"http://localhost:8080/technologies/1"                }             }          },          {             "id":2,             "description":"B",             "_links":{                "self":{                   "href":"http://localhost:8080/technologies/2"                }             }          }       ]    } } 

I want the response to be like this:

{    "_links":{       "self":{          "href":"http://localhost:8080/technologies"       }    },    "technologies":[       {          "id":1,          "description":"A",          "_links":{             "self":{                "href":"http://localhost:8080/technologies/1"             }          }       },       {          "id":2,          "description":"B",          "_links":{             "self":{                "href":"http://localhost:8080/technologies/2"             }          }       }    ] } 

My TechnologiesController:

@RestController @ExposesResourceFor(Technology.class) @RequestMapping(value = "/technologies") public class TechnologiesController {     ...     @ResquestMapping(method = RequestMethod.GET, produces = "application/vnd.xpto-technologies.text+json")     public Resources<Resource<Technology>> getAllTechnologies() {         List<Technology> technologies = technologyGateway.getAllTechnologies();         Resources<<Resource<Technology>> resources = new Resources<Resource<Technology>>(technologyResourceAssembler.toResources(technologies));         resources.add(linkTo(methodOn(TechnologiesController.class).getAllTechnologies()).withSelfRel());         return resources;     } 

The configuration class has the annotation @EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL).

What is the best way to produce the response without the "_embedded"?

Answer 1

As the documentation says

application/hal+json responses should be sent to requests that accept application/json

In order to omit _embedded in you response you'll need to add

spring.hateoas.use-hal-as-default-json-media-type=false 

to application.properties.
