spring - Autowiring not working for @Repository -

i trying create simple rest service stores data in db. sample architecture going rest controller mvc-controller, instantiates entity , tries store in db via autowired repository. rest service correctly invoked , replies has to; however, storing entity fails , autowired repository null. can help?

my rest service:

@restcontroller @requestmapping("/coord") public class coordservice {      @requestmapping(value = "/{name}", method = requestmethod.get)     public string getmuseo(@pathvariable string name) {         string result = "hello " + name + ", saving on db.";         new coordcontroller().savecoord();          return result;     } } 

my application business logic (controller in mvc):

@component public class coordcontroller {     @autowired     private coordrepository coordrepository;      public void savecoord() {         system.out.println("ok controller");          coord cg = new coord();         system.out.println("ok new");         cg.setcoord("xyz");         cg.setid(1l);          if (coordrepository == null) {             system.out.println("rep null!");         } else             coordrepository.save(cg);          system.out.println("ok save()");     } } 

my entity:

@entity @configurable public class coord extends identifiableentity {      @notnull     private string coord;      public string getcoord() {         return this.coord;     }      public void setcoord(string coord) {         this.coord = coord;     } } 

my repository:

@repository public interface coordrepository extends     jpaspecificationexecutor<coord>,     jparepository<coord, long> { }

your problem here

new coordcontroller().savecoord(); 

you need autowire coordcontroller coordservice. using new coordcontroller(), creating instance of coordcontroller not managed spring fields not autowired.

@restcontroller @requestmapping("/coord") public class coordservice {      @autowired     private coordcontroller coordcontroller;      @requestmapping(value = "/{name}", method = requestmethod.get)     public string getmuseo(@pathvariable string name) {         string result = "hello " + name + ", saving on db.";         coordcontroller.savecoord();          return result;     } } 

by way, coordservice class should named coordcontroller since controller (it has @restcontroller annotation!) , coordcontroller should coordservice since contains business logic.
