java - Get column names in result set Spring data JPA -


i have simple procedure lists out users. using @namedstoredprocedurequeries procedure declaration , used entitymanager.createnamedstoredprocedurequery storedprocedurequery.

it returns result need column name know value column.

my code goes this

entity class

@entity @namedstoredprocedurequeries({ @namedstoredprocedurequery(name =      "sgetuserlist", procedurename = "sgetuserlist", parameters = {      @storedprocedureparameter(mode = parametermode.in, name = "user_id", type =      integer.class) })  }) public class user {     @id     @generatedvalue(strategy = generationtype.auto)     private integer id;      private string name;      private string email;      //getters , setters }

custom repositoty

public interface userrepositorycustom {     list<?> testproc() ; }

repository

public interface userrepository extends jparepository<user, long>,  userrepositorycustom{  }

repository implementation

public class userrepositoryimpl implements userrepositorycustom{      @persistencecontext     entitymanager em;      public list<object> testproc() {          storedprocedurequery q = em.createnamedstoredprocedurequery("sgetuserlist");         q.setparameter("user_id", 1);         list<object> res = q.getresultlist();          return res;     } }

i need result column names.

i'm not sure understand trying here. if want users using spring data shouldn't implementing userrepository. spring data you.

in fact jparepository has method need.

list<user> findall();

you can call list of users , won't need worry column names.

just inject repository need , call method users:

@autowire userrepository userrepository;  list<users> allusers = userrepository.findall();

edit: if there particular reason want use stored procedures though there spring data way of doing without implementing userrepository yourself. can defining following method:

public interface userrepository extends jparepository<user, long>{    @procedure(name = "sgetuserlist")    list<user> sgetuserlist(@param("user_id") integer userid);  }

again there shouldn't issue resolving column names method.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...
