Question

我正在尝试使用简单的登录页面制作Spring Boot应用程序，但是当我尝试将@Autowired与我创建的接口一起使用时，似乎是一个问题。我读了7-8个类似的问题，但是我发现那里的答案对我没有用。当我在消耗JpaRepository的接口上使用@Autowired时，效果很好。

我的结构是：

我的软件包与我的应用程序文件处于同一级别。

这是我的控制人

@Controller
@RequestMapping(value = "/users")
public class LoginContoller     {



@Autowired
UsersRepositoryCustom usersRepositoryCustom;

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginForm(){
    return "login";
}

@RequestMapping(value = "/login", method = RequestMethod.POST)
public @ResponseBody
String verifyLogin(@RequestParam String name, @RequestParam String password) {

    System.out.println("Controller: name: " + name + " pass " + password);
    Users users=usersRepositoryCustom.loginUser(name, password);
    if (users==null) {
        System.out.println("login control user null");
        return "login";
    }

    return "users/all";
}
}

存储库：

    @Repository
    public interface UsersRepositoryCustom {
        Users loginUser(String name, String password);
    }

我认为这没有帮助，但这是实现方式

    public abstract class UserImpl implements UsersRepositoryCustom {


        @Autowired
        UsersRepository usersRepository;

        @Override
        public Users loginUser(String name, String password) {
            System.out.println("UserImpl: nume: " + name + " pass " + password);
            Users user=usersRepository.findByUsername(name);
            if (user != null && user.getPassword().equals(password)) {
                System.out.println("User Login"+user.getId()+"  "+user.getUsername());
                return user;
            }
            return null;
        }
    }

我尝试使用@ EnableJpaRepositories，@ EnableAutoConfiguration，但这没用

这是错误：

说明：

Field usersRepositoryCustom in com.asg1.asg1.controllers.LoginContoller required a bean of type 'com.asg1.asg1.repository.UsersRepositoryCustom' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.asg1.asg1.repository.UsersRepositoryCustom' in your configuration.


Process finished with exit code 1

Spring字段需要一个找不到类型的bean
