Question

我正在尝试在我的代码中使用用户存储库，但是intellij给了我错误。

interface is not allowed for non abstract beans

我有以下设置。

@Entity
public class User {

    @Id
    private long id;
    private String firstName;
    private String lastName;
    private String profileUrl;
    private String email;
    private String location;

    protected User(){};

    public User(String first, String last, String profileUrl, String email, String location){
        this.firstName = first;
        this.lastName = last;
        this.profileUrl = profileUrl;
        this.email = email;
        this.location = location;

    }

    public User(Person person){
        this.firstName = person.getName().getGivenName();
        this.lastName = person.getName().getFamilyName();
        this.profileUrl = person.getImage().getUrl();
        this.email = person.getEmails().get(0).getValue();
        this.location = person.getCurrentLocation();
    }
}


public interface UserRepository extends CrudRepository<User, Long> {

    List<User> findByProfileId(long id);
}

我尝试使用@Service和@Repository对此进行注释，但无济于事。

@Component
public class UserRepositoryImpl {

    @Autowired
    private UserRepository userRepository;


    public void doSomething() {
        List<User> byProfileId = userRepository.findByProfileId(100);
    }
}

    </bean>

    <tx:annotation-driven transaction-manager="txManager"/>    
</beans>

我的spring.xml行中出现错误，我在那里定义了我的userRepository bean。

提前致谢。

Answer 1

缺少

@Repository，尝试在repo的接口上面添加并删除Spring中不允许的bean声明。

Answer 2

我相信你只需要删除这一行：

<bean id="userRepository" class="com.planit.persistence.registration.UserRepository"/>

请参阅SpringData文档here。
