I've got a simple RepositoryRestResource based off of the guides on spring.io

@RepositoryRestResource(collectionResourceRel = "people", path = "people")
public interface PersonRepository extends PagingAndSortingRepository<Person, Long>{

    List<Person> findByLastName(@Param("name")  String lastName);

}

This does indeed work, as my REST client returns

{
  "_links" : {
    "people" : {
      "href" : "http://127.0.0.1:8080/people{?page,size,sort}",
      "templated" : true
    },
    "profile" : {
      "href" : "http://127.0.0.1:8080/profile"
    }
  }
}

But my question is, where does the http://127.0.0.1:8080 part of the _links come from and how can I change it? When my application goes to production (or any of my environments, like local or dev), I'd rather be able to see something like http://api.mydomain.com.

If it matters, I'm compiling my program with mvn package and running it as a standalone jar on the server.
