应用程序上下文中某些Bean的依赖关系形成一个循环 [英] The dependencies of some of the beans in the application context form a cycle

问题描述

我正在使用JPA开发Spring Boot v1.4.2.RELEASE应用程序.

I'm working on a Spring Boot v1.4.2.RELEASE application with JPA.

我定义了存储库接口和实现

I defined repository interfaces and implementations

存储库

@Repository
public interface ARepository extends CrudRepository<A, String>, ARepositoryCustom, JpaSpecificationExecutor<A> {
}

ARepositoryCustom

@Repository
public interface ARepositoryCustom {
    Page<A> findA(findAForm form, Pageable pageable);
}

ARepositoryImpl

@Repository
public class ARepositoryImpl implements ARepositoryCustom {
    @Autowired
    private ARepository aRepository;
    @Override
    public Page<A> findA(findAForm form, Pageable pageable) {
        return aRepository.findAll(
                where(ASpecs.codeLike(form.getCode()))
                .and(ASpecs.labelLike(form.getLabel()))
                .and(ASpecs.isActive()),
                pageable);
    }
}

还有一项服务 AServiceImpl

@Service
public class AServiceImpl implements AService {
    private ARepository aRepository;
    public AServiceImpl(ARepository aRepository) {
        super();
        this.aRepository = aRepository;
    }
    ...
}

我的应用程序不会以以下消息开头:

My application won't start with the message :

***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

|  aRepositoryImpl
└─────┘

我遵循了 http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.single-repository-行为

请帮助！

推荐答案

对于您的原始问题有一个简单的解决方法: 只需从ARepositoryCustom和ARepositoryImpl中删除@Repository. 保留所有命名和接口/类层次结构.都还可以.

There's a simple fix for your original problem: Just remove @Repository from ARepositoryCustom and from ARepositoryImpl. Keep all the naming and interface/class hierarchies. They are all OK.
