Spring boot CrudRepo定义bean

Question

@Service("userService")
public class UserServiceImpl implements UserService {

  @Autowired
  private UserRepository userRepository;

  @Autowired
  private RoleRepository roleRepository;
}

@Repository("userRepository")
public interface UserRepository extends CrudRepository<User, Long> {
     User findByEmail(String email);
}

Description:

Field userRepository in com.projectWS.service.UserServiceImpl required a 
bean of type 'com.projectWS.repo.UserRepository' that could not be found.

Action:

Consider defining a bean of type 'com.projectWS.repo.UserRepository' in your 
configuration.

@SpringBootApplication
@Configuration
@EnableWebMvc
public class Main {

   public static void main(String[] args) {
    SpringApplication.run(Main.class, args);
   }
}

Answer 1

最有可能的是，您的main类是在包中定义的，而您的其他包没有被扫描。

尝试使用以下方法注释main类：

@ComponentScan("com.projectWS")

根据错误消息判断并假设包级别的顶部从com.projectws开始
