本文介绍了我的自定义存储库实现中的CrudRepository的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我试图在我的自定义实现中获取对我的存储库接口(提供的任何Spring JPA方法。 code>,或者我可能在UserRepository中创建的任何其他方法。



有关如何解决此问题的任何建议?

任何帮助将不胜感激。编辑:正如@ shelley的回答中提到的,我能够通过进行3次更改来解决这个问题:

解决方案

一些小的事情需要改变才能使用:


  • 删除 @存储库自定义存储库接口的注释( UserRepositoryExtension )。

  • 定制存储库实现实际上应该命名为< StandardRepository> Impl ,而不是< CustomRepository> Impl 。在你的代码示例中,这应该是 UserRepositoryImpl ,而不是 UserRepositoryExtensionImpl 。



I am attempting to get a reference to my repository interface (UserRepository) that extends CrudRepository within my custom implementation (UserRepositoryExtensionImpl) in order to gain access to all the methods provided by Spring JPA.

Crud Extension:

@Repository
public interface UserRepository extends CrudRepository<User, String>, UserRepositoryExtension<RosterUser> {
    ...any custom spring JPA methods...
}

Extension Interface:

@Repository
public interface UserRepositoryExtension <T> {
   public T put(T entity);
}

Custom Implementation:

public class UserRepositoryExtensionImpl implements UserRepositoryExtension<User> {

    UserRepository userRepository;

    @Autowired
    public UserRepositoryExtensionImpl(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @Override
    public User put(User user) {
        System.out.println(user + "was put");
        // ...put logic here
        return null;
    }...
}

However, I am unable to inject UserRepository since a circular dependency exists (given that UserRepository extends the interface implemented by my UserRepositoryImpl). I am getting the following error:

org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name '    userRepositoryImpl': Requested bean is currently in creation: Is there an unresolvable circular     reference?

A possible, but less than ideal solution would be to inject and EntityManager into UserRepositoryImp, but in that case, I do not have access to any of the Spring JPA methods provided by CrudRepository, or any additional methods that I might have created in UserRepository.

Any suggestions on how to get around this?

Any help would be greatly appreciated.

EDIT: As mentioned in @shelley's answer, I was able to solve this by making 3 changes:

SUCCESS!

解决方案

A couple small things need to be changed in order for this to work:

  • Remove the @Repository annotation from the custom repository interface (UserRepositoryExtension).

  • The custom repository implementation should actually be named "<StandardRepository>Impl" rather than "<CustomRepository>Impl". In your code example, this should be UserRepositoryImpl instead of UserRepositoryExtensionImpl.
