使用JPA在spring boot中实现DAO

Question

I am writing query using In operator in spring boot using JPA

select * from data where name in ("XYZ","XY")

I am unable to implement DAO implementation for the following input in spring boot with JPA.

 {"name":["XYZ","XY"]}

Controller

@PostMapping("/embdata/dto/name")
public List getByBatchIdsWithDTO(@RequestBody EmbDataDTO dto){
    return service.getBatchIds(dto);
}

Service Method:

    List<Data> obj=repo.findBybatchID(List<String> name)

Repo Interface:

    List<Data> findByBatchIdIn(List wageId);

My entity Class

@Entity
@Data
@Table(name="data")
public class Data{

    @Id @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id")
    int id;

    @Column(name="name")
    String name;

    @Column(name="address")
    String address;
}

My DTO class:

@Data
public class EmbDataDTO {
   private int id;
   private String name;
   private String address;
}

please help me to implement for the following input.

Answer 1

Your repo should look like :

@Repository
@Transactional
class YourRepo {
  List<Data> findByBatchIdIn(List wageId) {
    Query q = entityManager.createQuery("select * from data where name in (:list)");
    q.setListParameter("list", wageId); 
    return q.execute(); 
  }
}

At least something like that.
