Spring boot CrudRepo 定义一个bean [英] Spring boot CrudRepo Define a bean

问题描述

我在 Spring Boot 中遇到了有关存储库的问题.我有一项服务:

I have a problem in spring boot concerning repositories. I have a service :

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

  @Autowired
  private UserRepository userRepository;

  @Autowired
  private RoleRepository roleRepository;
}

和这里的回购:

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

当我运行应用程序时，我收到此消息:

When I run the app I get this message :

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.

请帮帮我，我太绝望了...这是我的主要课程:

Please help me I'm so desperate... this is my main class:

@SpringBootApplication
@Configuration
@EnableWebMvc
public class Main {

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

另一个问题是，@EnableJpaRepositories 没有被识别！！

Another problem is , @EnableJpaRepositories doesn't get recognized !!

推荐答案

很可能你的 Main 类是在一个包中定义的，而你的其他包没有被扫描.

most likely your Main class is defined within a package and your other packages are not getting scanned.

尝试注释您的 Main 类:

@ComponentScan("com.projectWS")

根据您的错误消息判断并假设您的包级别的顶部从 com.projectWS

judging by your error message and assuming that the top of your package level starts at com.projectWS
