then when i breakpoint on findAll in controller i can see id in array List
#GetMapping("/list")
#ResponseBody
public List<Book> findAll() {
return bookRepository.findAll();
}
but in generated-request.http or in frontend (react table) , extended property (id) doesn't load
GET http://localhost:8080/rest/books/list
and the result as follows:
{

}
please help me how i can see extended property in frontend

I tried to select all columns from the table MAGICNOTIFY_CARD_INFO, so i wrote a code;
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(MagicnotifyApplication.class, args);
MagicnotifyCardInfoRepository magicnotifyCardInfoRepository =
context.getBean(MagicnotifyCardInfoRepository.class);
magicnotifyCardInfoRepository.findAll();
//SpringApplication.run(MagicnotifyApplication.class, args);
}
and this is the entity i wanted to select;
public class MagicnotifyCardInfoID implements Serializable {
#Column(name = "koname")
private String koname;
#Column(name = "name")
private String name;
#Column(name = "cardkingdom")
private String cardkingdom;
#Column(name = "cardkingdomfoil")
private String cardkingdomfoil;
#Column(name = "set")
private String set;
#Column(name = "setName")
private String setName;
#Column(name = "reldate")
private Date reldate;
#Column(name = "rarity")
private String rarity;
#Column(name = "uuid")
private String uuid;
#ManyToOne
private MagicnotifyUuidName magicnotifyUuidName;
#ManyToOne
private MagicnotifySetInfo magicnotifySetInfo;
}
public class MagicnotifyCardInfo implements Serializable {
#EmbeddedId
private MagicnotifyPriceID id;
}
public interface MagicnotifyCardInfoRepository extends JpaRepository<MagicnotifyCardInfo, Long> {
#Query(value = "SELECT * FROM MAGICNOTIFY_CARD_INFO", nativeQuery = true)
List<MagicnotifyCardInfo> findByAll();
List<MagicnotifyCardInfo> findAll();
}
but after querying, it tries to select other column item from table
MAGICNOTIFY_PRICE;
public class MagicnotifyPriceID implements Serializable {
#Column(name = "foil")
private BigDecimal foil;
#Column(name = "normal")
private BigDecimal normal;
#Column(name = "date")
private Date date;
#Column(name = "key")
private String key;
#ManyToOne
private MagicnotifyUuidName id;
}
public class MagicnotifyPrice implements Serializable {
#EmbeddedId
private MagicnotifyPriceID id;
}
I'm not sure why it happens from differently mapped two tables; how can i select from initial table MAGICNOTIFY_CARD_INFO and select from its columns?
First of all, you have not mentioned any primary key using #Id annotation inside either of your MagicnotifyCardInfoID class or MagicnotifyPriceID class
Secondly, you have given same #EmbeddedId fields "MagicnotifyPriceID id" in both the below classes
public class MagicnotifyCardInfo implements Serializable {
#EmbeddedId
private MagicnotifyPriceID id;
}
public class MagicnotifyPrice implements Serializable {
#EmbeddedId
private MagicnotifyPriceID id;
}
I don't see #Embeddable used anywhere in your program
Please refer https://www.baeldung.com/jpa-embedded-embeddable
public interface MagicnotifyCardInfoRepository extends JpaRepository<MagicnotifyCardInfo, Long> {
#Query(value = "SELECT * FROM MAGICNOTIFY_CARD_INFO", nativeQuery = true)
List<MagicnotifyCardInfo> findByAll();
List<MagicnotifyCardInfo> findAll();
}
In the above class you are passing "JpaRepository<MagicnotifyCardInfo, Long>"
Long as the data type of a primary key in your entity "MagicnotifyCardInfo"
which does not even exist.
Please fix these and try again.
I'm building a RESTful API GET method with Spring Boot to get return of a Bill entity as JSON from database. The return is not expected as it has many duplicated values and a StackOverFlowError.

{

"id": 2
"name": Wine
// other attributes of MenuItem
},
"quantity": 4

In the class MenuItem you should add the annotation #JsonIgnore to prevent an infinite loop in the JSON format returned; a bill has a BillDetails , a BillDetails has a MenuItem , a MenuItem Has a BillDetails , every BillDetail has a List of MenuItem ...
#Entity
#Table(name = "menuItem",
uniqueConstraints = {
#UniqueConstraint(name = "menu_item_name_unique", columnNames = "name")
}
)
public class MenuItem {
#Id
#GeneratedValue(
strategy = GenerationType.IDENTITY

#Column(name = "menu_item_id")
private Long id;
private ItemType type;
private String name;
private String description;
private String imgUrl;
private Double price;
private MenuItemStatus status = MenuItemStatus.ENABLED;
// ADD JSON IGNORE ANNOTATION HERE :

#OneToMany(mappedBy = "menuItem", cascade = CascadeType.ALL)
private List<BillDetail> billDetails = new ArrayList<>();
I have the following code...
It's an application where the user has a wall, and on that wall there can be several games.
#Entity
#Table(name = "tb_user")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
#OneToOne(mappedBy = "user",fetch = FetchType.EAGER)
private Mural mural;
public User() {
}
public User(Long id, String name, Mural mural) {
this.id = id;
this.name = name;
this.mural = mural;
//getters and setters...
}
#Entity
#Table(name = "tb_mural")
public class Mural implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
#ManyToMany
#JoinTable(name = "tb_mural_games",
joinColumns = #JoinColumn(name = "mural_id"),
inverseJoinColumns = #JoinColumn(name = "games_id"))
private Set<Game> games = new HashSet<>();
#OneToOne
#JoinColumn(name = "user_id")
private User user;
public Mural() {
}
public Mural(Long id, String name, User user) {
this.id = id;
this.name = name;
this.user = user;
}
//getters and setters...
And the following request...
#GetMapping
public ResponseEntity<List<User>> findAll(){
List<User> list = repository.findAll();
return ResponseEntity.ok().body(list);
}
But I have the following error...
Resolved [org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: failed to lazily initialize a collection of role... continue...
I tried using FETCH.EAGER but it doesn't work, it only works if I use jsonignore, but I would like it to return the "mural" in the user request.
The user request data are these =
[
{
"id": 1,
"name": "Anderson Conforto"
},
{
"id": 2,
"name": "Airton Conforto"
}
]
but using jsonignore, it ignores the mural class data, and that's not what I'd like.
Put the JsonIgnore in the Mural class on
#OneToOne
#JoinColumn(name = "user_id")
private User user;
Also try to avoid directly returning entities to the end user. Either try to map the entity to DTO or use projection (https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#projections).
I have two Entities in my spring boot application. I am working with dtos and displaying my dto in the end. But I am getting the wrong output from my getRequest. My first entity is MeetingSetting which can have multiple MeetingTimes and inside MeetingTime I have meetingName as a foreign key. I want to display meetingTime like this:
{
"id": 1,
"date": "2021-06-31",
"startTime": "15:30",
"endTime": "16:30",
"meetingName": "Test"
}
But I am getting instead this one:
{
"id": 1,
"date": "2021-06-31",
"startTime": "15:30",
"endTime": "16:30",
"meetingName": {
"id": 1,
"meetingName": "Tewasddweewrst2",
"meetingUrl": null,
"meetingPw": ""
}
}
Could someone take a look at my code and tell me what I am doing wrong?
MeetingSetting Entity::
#Entity
#Table(name = "meeting_settings")
#Setter
#Getter
public class MeetingsSetting implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "meeting_name", unique = true)
private String meetingName;
#Column(name = "meeting_url")
private String meetingUrl;
#Column(name = "meeting_pw")
private String meetingPw;
#OneToMany(mappedBy = "meetingName", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<MeetingTime> meetingTime = new HashSet<>();
}
MeetingSettingDTO:
#Getter
#Setter
public class MeetingSettingDTO {
private Long id;
#NotNull
private String meetingName;
#NotNull
private String meetingUrl;
#NotNull

#Getter
#Setter
public class MeetingTimeDTO {
private Long id;
#NotNull
private String date;
#NotNull
private String startTime;
#NotNull
private String endTime;
private MeetingSettingDTO meetingName;
}
In my service I am first getting MeetingTime as an entity from my repository then converting it to DTO and returning it for my controller:
#Service
public class MeetingTimeService {
ModelMapper modelMapper = new ModelMapper();
#Autowired
MeetingTimeRepository meetingTimeRepository;
public List<MeetingTimeDTO> findAllMeetingTimes(){
List<MeetingTime> meetingTimeList = meetingTimeRepository.findAll();
return meetingTimeList.stream()
.map(this::convertToDto)
.collect(Collectors.toList());
}
private MeetingTimeDTO convertToDto(MeetingTime meetingTime) {
MeetingTimeDTO meetingTimeDTO = modelMapper.map(meetingTime, MeetingTimeDTO.class);
return meetingTimeDTO;
}
}
Controller:
#GetMapping(value = "/" )
public List<MeetingTimeDTO> getAllTimes() {
return meetingTimeService.findAllMeetingTimes();
}
In MeetingTimeDTO:
private MeetingSettingDTO meetingName;
The type needs to be changed to:
private string meetingName;
I have not worked with ModelMapper so cannot help you with how to map a specific field from the related object but this answer here seems to provide the info needed.
I'm doing a registration and I have the fields
Nome:
Data de Nascimento:
Inscrição Estadual:
Nome Responsável:
CPF Responsável:
Cep:
Bloco:
Número:
when i saving, I can not write data from the PessoasEnderecos class, the other data is recording normal. I'm getting all the data on the screen so much that I debugged the browser to see ..
It shows no error. Does anyone know what I'm missing ??
my class Pacientes
#Entity
#Table(name = "pacientes", schema = "sau")
public class Pacientes implements Serializable {

my methods
class Controller
#RequestMapping(method = RequestMethod.POST, value = "/pacientes")
public Pacientes cadastrarPacientes(#RequestBody Pacientes pac) {
return pacientesService.cadastrar(pac);
}
class service
public Pacientes cadastrar(Pacientes pacientes){
return pacRepository.save(pacientes);
}
class repository
public interface PacientesRepository extends JpaRepository<Pacientes, Integer> {
}
You should also add the linkage #OneToMany in Pacientes:
public class Pacientes implements Serializable {
...
#OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "pessoa")
#PrimaryKeyJoinColumn
private List<PessoasEnderecos> pessoasEnderecos = new ArrayList<>();
Update:
and your JSON should be something like this:
{
"nomeResponsavel": "abc",
"pessoasEnderecos": [
{
"bloco": "sdds",
"cep": "sdasdsad",
"numero": "sdasdsa"
}
]
}
