sql - Why does Hibernate JPA lose the column names when queried? -

when query hibernate a:

"select business relationship a", jaxrs gives me column names in json, when execute query:

"select a.firstname, a.lastname business relationship a" json contains info without column names.

for instance:

{ firstname: "simon" }

becomes:

{ "simon" }

select business relationship

is jpql query returns list<account>. list serialized json array of objects.

on other hand,

select a.firstname, a.lastname business relationship

is jpql query returns list<object[]>. list serialized json array of arrays.

and finally,

select a.firstname business relationship

is jpql query returns list<string>. list serialized json array of strings.
