With @Controller you are defining a Model-View-Controller (MVC) endpoint for returning your view templates. So with Iterable<Students> Spring is looking for a Students template in your src/main/resources/templates folder because it is interpreted as a View name.

If you want to create a REST endpoint which returns a list of Student objects you should use @RestController at your class which adds the Spring annotation @RequestBody automatically.

Furthermore @Path("XYZ") should be replaced with @RequestMapping("XYZ") in Spring and @AutoWired with @Autowired.

An working example could look like the following:

@RequestMapping("/students")
@RestController
public class StudentsController {

    @Autowired
    StudentServices st;

    @RequestMapping(value="/", method = RequestMethod.GET)
    public Iterable<Students> getAllStudents() {
          Iterable<Students> list = st.getAllStudents();
          return list
}
