i need to adjust the result of findall result jpa repository. Here is the entity

public class AppComponent {
    @Id
    @GeneratedValue(strategy = GenerationType.UUID)
    private UUID id;

    @Column(name = "sequence")
    private int sequence;

    @OneToMany(
            fetch = FetchType.LAZY,
            cascade = CascadeType.ALL,
            mappedBy = "appComponent"
    )
    @JsonManagedReference
    private List<AppElement> appElements;
}

i am using stream to adjust the structure, the code is working. the problem is, i am hard coding the key of the map. how to get the field name, so i dont need to write it like that? or are there any better ways to do it?

appComponentGroup.getAppComponents().stream()
  .map(
    appComponent -> Map.of(
      "sequence",
      appComponent.getSequence(),
      "elements",
      appComponent.getAppElements().stream().collect(
        Collectors.toMap(
          appElement -> appElement.getName(),
          appElement -> appElement.getValue()
        )
      )
    )
  )

the output looks like this

"review": [{
  "sequence": 1,
  "elements": {
    "reviewer": "john doe",
    "rating": 5
  }
}]
