将客户行为添加到 CDI 上下文中的所有 spring 数据 Jpa 存储库 [英] Add customer behaviour to all spring data Jpa repositories in CDI context

问题描述

我使用 CDI 成功注入了 jpa 存储库.我想向所有存储库添加自定义行为(软删除).使用 spring 时，我可以通过指定存储库基类来启用客户行为

Am successfully injecting jpa repositories using CDI. I wanted to add custom behaviour(soft deletes) to all repositories. When using spring I can enable customer behaviour by specifying the repository base class

@EnableJpaRepositories(repositoryBaseClass = StagedRepositoryImpl.class)

如何在 CDI 中指定相同的内容?提前致谢.

How do I specify the same in CDI? Thanks in advance.

推荐答案

要将自定义行为添加到 Jpa 存储库(在您的情况下是删除)，

To add custom behaviour to Jpa Repositories(in your case for delete),

1. 创建一个如下所示的基本存储库:

1. Create a base repository like below:

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

    @Override
    default void delete(T entity){
        // your implementation
    }
}

2. 现在从自定义存储库(即 BaseRepository)继承 Jpa 存储库，如下所示:

2. Now inherit Jpa Repositories from custom repository(i.e BaseRepository) like below:

public interface EmployeeRepository extends BaseRepository<Employee, Long> {
}

3. 将您的存储库注入 Service 类并调用 delete 方法.

3. Inject your repository into Service class and call the delete method.

@Service
class EmployeeService {

    @Inject
    private EmployeeRepository employeeRepository;

    public void delete(Long id) {
        employeeRepository.delete(id);
    }
}

现在，每当您对 BaseRepository 的子存储库调用 delete 时，您的自定义删除实现都会被调用.

Now whenever you call delete on repositories which are child of BaseRepository, your custom implementation for delete will be invoked.
