spring-hateoas with `use-hal-as-default-json-media-type=false` still response `application/hal+json` by default

I want to disable HAL format by default.

Flow the document, I set this property.

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

Then test it:

1. Request with header Accept: application/json.

Header: Content-Type: application/json;charset=UTF-8

Response:

{
  "links": {}
}

2. Request with header Accept: */* or without Accept header.

Header: Content-Type: application/hal+json;charset=UTF-8

Response:

{
  "_embedded": {},
  "_links": {}
}

The version of spring-boot is 1.5.3, and I use spring-boot-starter-hateoas.

Is anyway let hateoas to response json without HAL when no header specified?

Thanks a lot.

Update:

Here is a example base on the guide from spring.io.

Requests at: http://localhost:8080/greeting

Requests with header Accept: */*.

HTTP/1.1 200 
Content-Type: application/hal+json;charset=UTF-8

{
  "content":"Hello, World!",
  "_links":{
    "self":{
      "href":"http://localhost:8080/greeting?name=World"
    }
  }
}

Requests with header Accept: application/json.

HTTP/1.1 200 
Content-Type: application/json;charset=UTF-8

{
  "content":"Hello, World!",
  "_links":{
    "self":{
      "href":"http://localhost:8080/greeting?name=World"
    }
  }
}

I don't want HAL by default, so I add a config file resources/application.properties to the project.

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

And test again.

Requests with header Accept: */*.

HTTP/1.1 200 
Content-Type: application/hal+json;charset=UTF-8

{
  "content":"Hello, World!",
  "_links":{
    "self":{
      "href":"http://localhost:8080/greeting?name=World"
    }
  }
}

Requests with header Accept: application/json.

HTTP/1.1 200 
Content-Type: application/json;charset=UTF-8

{
  "content":"Hello, World!",
  "links":[
    {
      "rel":"self",
      "href":"http://localhost:8080/greeting?name=World"
    }
  ]
}
