I using @Autowired interface service in Spring Boot return null










-2














I do not understand why - even though I have declared @Autowired - my service is null.



@Autowired
private IUserService userService;

/**
* Get info User login
*/

public HashMap<String, Object> getUserInfo()
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
String userName = (String) authentication.getName();
User user = userService.findUserByUserName(userName); //userService is null

HashMap<String, Object> map = new HashMap<String, Object>();
map.put("user", user);
return map;

Make sure you have not instantiated object of interface implementation anywhere else in your code base.



Example of what you should not write while using @Autowired:



IUserService userService = new IUserServiceImplementation();
