我有一个RedisHash表,我已经在Spring数据中进行了如下建模:
@RedisHash("Entity")
@Data
@AllArgsConstructor
public class Entity implements Serializable {
private String id;
private String status;
private String name;
}
我有一个这样的EntityRepository:
@Repository
public interface EntityRepository extends CrudRepository<Entity, String> {}
然后,我有一个这样的EntityService:
@Service
public class EntityService {
@Autowired
private EntityRepository entityRepository;
public List<Entity> getAllByName(String name) {
// Code that gets all Entities stored in my redis table that have a certain name
}
public List<Entity> getAllByStatus(String status) {
// Code that gets all Entities stored in my redis table that have a certain status
}
如何在Redis中搜索所有具有特定名称/具有特定状态的实体?
最佳答案
我遵循了文档here并能够解决我的问题。我将QueryByExampleExecutor接口添加到我的存储库中,如下所示:
@Repository
public interface EntityRepository extends CrudRepository<Entity, String>, QueryByExampleExecutor<Entity> {}
使用Example类,我实现了getAllByName,如下所示:
public List<Entity> getAllByName(String name) {
Entity entity = new Entity();
entity.setName(name);
Example<Entity> example = Example.of(entity);
entityRepository.findAll(example);
//...
}
