无法自动装配存储库服务Spring JPA [英] Cannot Autowire repository service Spring JPA

问题描述

我试图在我的代码中使用用户存储库，但是intellij给了我错误。

I am trying to use a User repository in my code, but intellij is giving me the error.

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);
}

我试图用 @Service <注释这个/ code>和 @Repository 但无济于事。

@Component
public class UserRepositoryImpl {

    @Autowired
    private UserRepository userRepository;


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

        <property name="entityManagerFactory" ref="myEmf"/>
    </bean>

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

在spring.xml的行中出错我在哪里定义 userRepository bean。

Error occurs in the line of my spring.xml where I am defining my userRepository bean.

提前致谢。

推荐答案

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。

@Repository is missing, try adding above the interface of the repo and remove bean declaration that is not allowed in Spring.
