We will create a new RestController annotation called TodoController. The code for the retrieveTodos method is as follows:

    @RestController
    public class TodoController {

     @Autowired
     private TodoService todoService;

     @GetMapping("/users/{name}/todos")
     public List<Todo> retrieveTodos(@PathVariable String name) {
       return todoService.retrieveTodos(name);
     }

    }

A couple of things to note are as follows:

• We are autowiring the todo service using the @Autowired annotation.
• We use the @GetMapping annotation to map the GET request for the "/users/{name}/todos" URI to the retrieveTodos method.
