本文介绍了没有类型为'org.springframework.data.jpa.repository.support.JpaEntityInformation的合格Bean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

我正在尝试通过BaseRepository接口和BaseRepositoryImpl扩展** SimpleJpaRepository **.
Tha BaseRepositoryImpl扩展了** SimpleJpaRepository **并实现了BaseRepository.

I'm trying to extend the **SimpleJpaRepository ** by BaseRepository interface and the BaseRepositoryImpl.
Tha BaseRepositoryImpl extends **SimpleJpaRepository ** and implements BaseRepository.

此外，我还有一些其他存储库，例如CandidateRepository和EmployeeRepository，它们扩展了BaseRepository.

In addition, I have some other Repositories such as CandidateRepository and EmployeeRepository that extends the BaseRepository.

在下面您可以看到错误后的代码:

Below you can see the code following the error:

要查看项目结构，请点击此处 

    @NoRepositoryBean  
    public interface BaseRepository<T, ID extends Serializable> extends JpaRepository<T, ID>{
//..
}


@Repository
public abstract class BaseRepositoryImpl<T, ID extends Serializable> extends 
                                                    SimpleJpaRepository<T, ID> implements BaseRepository<T, ID>{

    private final EntityManager em;

    public BaseRepositoryImpl(JpaEntityInformation<T,ID> entityInformation, 
                                EntityManager entityManager) {

      super(entityInformation, entityManager);
      this.em = entityManager;

  }
  //..
}

扩展存储库:

@NoRepositoryBean
    public interface CandidateRepository extends BaseRepository<DatCandidate, UUID>{

        //..
    }


@Repository(value="CandidateRepositoryImpl")
public class CandidateRepositoryImpl extends BaseRepositoryImpl<DatCandidate, UUID> implements CandidateRepository{


    public CandidateRepositoryImpl(
            JpaEntityInformation<DatCandidate, UUID> entityInformation,
            EntityManager entityManager) {

        super(entityInformation, entityManager);

    }
}

这是我的配置:

服务:

            ) {
        this.candidateRepository = (CandidateRepositoryImpl)candidateRepository;
    }
}

错误:

通过构造函数参数0表示的不满足的依赖关系；嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException:否类型的合格豆'org.springframework.data.jpa.repository.support.JpaEntityInformation'可用:至少需要1个符合条件的bean作为自动线候选者.依赖项注释:{}

Dependency annotations: {}

我遵循了Spring JPA文档，但无法理解错误

I followed the Spring JPA documentation, but can't understand the error

推荐答案

您在这里所做的事情有些奇怪.

You are doing a somewhat weird combination of things here.

一方面，通过在 CandidateRepository 上使用 @NoRepositoryBean 并提供自己的实现，可以有效地禁用所有Spring Data内容.但是然后您的实现是基于扩展 SimpleJpaRepository< T，ID> 的，它是Spring Data的核心组件，但是由于您基本上禁用了它，因此配置不正确.

On the one hand, you effectively disable all the Spring Data stuff by using @NoRepositoryBean on CandidateRepository and providing your own implementation. But then your implementation is based extends SimpleJpaRepository<T, ID> which is a core component of Spring Data but it doesn't get configured properly since you basically disabled it.

我想是时候下定决心了:

I guess it's time to make up your mind:

  1. 是否要更改 SimpleJpaRepository< T，ID> 提供的行为?可能在基本实现中添加方法.

  1. Do you want to change the behavior that is provided by SimpleJpaRepository<T, ID>? Possibly adding methods to your base implementation.

如果这样扩展它，则使构造函数保持不变，并将其用作您的此处是有关如何执行此操作的教程.

If so extend it, leaving constructors as they are and use it as your repositoryBaseClass. Here is a tutorial how to do that.

只需为一个(或某些)存储库提供自定义实现.然后使用自定义实现.

Just provide custom implementation for one (or some) repositories. Then use custom implementations.
