SpringBoot Hibernate, CriteriaBuilder - java

Is it possible to fetch Data from 3 tables in hibernate where the controller is of a different model.

Base DemoController you have already a DemoService that you can reuse between other controlers. So if you have
#RestController
#RequestMapping("/api/abcServiceA")
public class DemoControllerA {
#Autowired
private DemoServiceA demoServiceA;
#RestController
#RequestMapping("/api/abcServiceB")
public class DemoControllerB {
#Autowired
private DemoServiceB demoServiceB;
You can create controler:
#RestController
#RequestMapping("/api/abcServiceB")
public class DemoControllerD {
#Autowired
private DemoServiceA demoServiceA;
#Autowired
private DemoServiceB demoServiceB;
Use this two services in one method:
#RequestMapping(value = "/list/v1/{user_id}/uid/{locationNoId}/location",method = RequestMethod.GET)
#ResponseBody
#ApiOperation(value = "Get all Lists", notes = "Get all Address related information")
public ResponseEntity<?>getAll(#PathVariable("user_id")int userId,
#PathVariable("locationNoId")int locationNoId) {
try {
ModelMapper modelMapper = new ModelMapper();
Type listType = new TypeToken<List<DemoDTO>>() {}.getType();
List<DemoDTO> listAllFromA = aemoServiceA.ListAll(userId, locationNoId);
List<DemoDTO> listAllFromB = aemoServiceB.ListAll(userId, locationNoId);
// do something with listAllFromA and listAllFromB
return new ResponseEntity<>(listAll, HttpStatus.OK);
} catch (Exception ex) {
String errorMessage;
errorMessage = ex.getMessage();
return new ResponseEntity<>(errorMessage, HttpStatus.BAD_REQUEST);
}
}

How to customize response from #query in springboot API

I have a problem with my API #query reponse in SpringBoot.
First I will show u my code:
#RestController
#RequestMapping("/api/osoba")
public class APIController {
#Autowired
private KsiazkaRepo ksiazkaRepo;
#JsonView(OnlyName.class)
#RequestMapping(method = RequestMethod.POST, value = "/getAll")
public Ksiazka find(#RequestParam("id") int id){
String autor = ksiazkaRepo.findInfoById(id);
Ksiazka ksiazka = new Ksiazka();
ksiazka.setAutor(autor);
return ksiazka;
}
**#Repository
public interface KsiazkaRepo extends JpaRepository<Ksiazka, Integer> {
#Query(value = "SELECT ksiazka.tytul, ksiazka.autor FROM IEci8d0gZc.ksiazka WHERE ksiazka.id_ksiazka = :id", nativeQuery = true)
String findInfoById(#Param("id") int id);
}**
#Entity
#Validated
public class Ksiazka {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int idKsiazka;
private int idKategoria;
private String isbn;
#JsonView(OnlyName.class)
private String tytul;
#JsonView(OnlyName.class)
private String autor;
private int stron;
private String wydawnictwo;
private int rokWydania;
private String opis;
public Ksiazka(){ }
public Ksiazka(int idKsiazka, int idKategoria, String isbn, String tytul, String autor, int stron, String wydawnictwo, int rokWydania, String opis) {
this.idKsiazka = idKsiazka;
this.idKategoria = idKategoria;
this.isbn = isbn;
this.tytul = tytul;
this.autor = autor;
this.stron = stron;
this.wydawnictwo = wydawnictwo;
this.rokWydania = rokWydania;
this.opis = opis;
}
public int getIdKsiazka() {
return idKsiazka;
}
public void setIdKsiazka(int idKsiazka) {
this.idKsiazka = idKsiazka;
}
public int getIdKategoria() {
return idKategoria;
}
public void setIdKategoria(int idKategoria) {
this.idKategoria = idKategoria;
}
public String getIsbn() {
return isbn;
}
public void setIsbn(String isbn) {
this.isbn = isbn;
}
public String getTytul() {
return tytul;
}
public void setTytul(String tytul) {
this.tytul = tytul;
}
public String getAutor() {
return autor;
}
public void setAutor(String autor) {
this.autor = autor;
}
public int getStron() {
return stron;
}
public void setStron(int stron) {
this.stron = stron;
}
public String getWydawnictwo() {
return wydawnictwo;
}
public void setWydawnictwo(String wydawnictwo) {
this.wydawnictwo = wydawnictwo;
}
public int getRokWydania() {
return rokWydania;
}
public void setRokWydania(int rokWydania) {
this.rokWydania = rokWydania;
}
public String getOpis() {
return opis;
}
public void setOpis(String opis) {
this.opis = opis;
}
And my interface OnlyName is empty.
When I'm using it like that like it is right not I can get simple response
Like:
{
"tytul": null,
"autor": "Mistrz czystego kodu. Kodeks postępowania profesjonalnych programistów,Robert C. Martin"
}
I understand that my response from #query is in String and that's why I'm getting only one result, but How should I change to get all String or something like that? Maybe String[]?
I can also create 2 different custom asking #query and get from them
1. imie,
2. nazwisko,
but this should not be the case.
Many thanks for help,
Ciao
UPDATE

Follow the steps here
In here, I am trying to tell you how to do this simply
Change the query , It should return list
#Query(value = "SELECT ksiazka.tytul, ksiazka.autor FROM IEci8d0gZc.ksiazka WHERE ksiazka.id_ksiazka = :id", nativeQuery = true)
List<String> findInfoById(#Param("id") int id); // here you can return result as list
Change the return type in "public Ksiazka find" as list
#RestController
#RequestMapping("/api/osoba")
public class APIController {
#Autowired
private KsiazkaRepo ksiazkaRepo;
#JsonView(OnlyName.class)
#RequestMapping(method = RequestMethod.POST, value = "/getAll")
public List<Ksiazka> find(#RequestParam("id") int id){
}
Inside body try to do get result as list ,
#RestController
#RequestMapping("/api/osoba")
public class APIController {
#Autowired
private KsiazkaRepo ksiazkaRepo;
#JsonView(OnlyName.class)
#RequestMapping(method = RequestMethod.POST, value = "/getAll")
public List<Ksiazka> find(#RequestParam("id") int id){
List<String> autor = ksiazkaRepo.findInfoById(id); // get result as as list
List<Ksiazka> ksiazkaList = new ArrayList<>(); // create list from Ksiazka
for (String autors : autor) { // returned result you can loop
Ksiazka ksiazka = new Ksiazka(); // create Object to Ksiazka
ksiazka.setAutor(autors);
ksiazkaList.add(ksiazka); //add created object to List
}
return ksiazkaList; // return your list
}

How should I design this addOrders method?

If you are using Spring Data then you will need to create a CrudRepository for each table you which to access. The CrudRepository allows you to easily manipulate data in your table using standard ORM practices. Here is a link with more details.
For more detailed info on how to use Spring Data check out this wonderful guide. This guide has become indispensable when working with Spring Data.

There are many options to this but i have used below approach so hope it helps you. The #Query annotation allows to execute native queries by setting the nativeQuery flag to true.
#Query(value = "select o.* from customer c inner join order o on c.customer_id = o.customer_id where o. = ?1", nativeQuery = true)
Please write sql according to your requirement.

ApplicationContext ctx = new GenericXmlApplicationContext("SpringConfig.xml");
public MongoOperations getMongoOpertion() {
MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");
return mongoOperation;
}
}

Look at your code.
You have declared _id as Long type.
#Id
private long _id;
But in your below methods you are passing String id to match the criteria.
So it is not working.
#Override
public Account findOne(String id) {
Account account = dbOperations.getMongoOpertion().findOne(Query.query(Criteria.where("_id").is(id)),
Account.class, "account");
return account;
}
#Override
public void delete(String id) {
Query query = new Query();
query.addCriteria(Criteria.where("id").is(id));
Account account = dbOperations.getMongoOpertion().findOne(query, Account.class);
dbOperations.getMongoOpertion().remove(account);
}

Why the same id is incremented when I save an object in the repository?

Whenever I call save() method the same ID is shared between three different entities and I don't know why ?
#Entity
public class Department {
#Id
#GeneratedValue
private Long departmentId;
private String name;
public Department(Long departmentId) {
this.departmentId = departmentId;
}
public Department() {
}
public Department(String name) {
this.name = name;
}
public Long getDepartmentId() {
return departmentId;
}
public void setDepartmentId(Long departmentId) {
this.departmentId = departmentId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
#Entity
public class Location {
#Id
#GeneratedValue
private Long locationId;
private String name;
public Location(Long locationId) {
this.locationId = locationId;
}
public Location() {
}
public Location(String name) {
this.name = name;
}
public Long getLocationId() {
return locationId;
}
public void setLocationId(Long locationId) {
this.locationId = locationId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
And this is my Controller:
#RestController
public class SettingsController {
#Autowired
private LocationRepository locationRepository;
#Autowired
private DepartmentRepository departmentRepository;
#Autowired
private RoleRepository roleRepository;
#RequestMapping(value = "/api/locations", method = RequestMethod.POST)
public ResponseEntity addLocation(#RequestBody DataForm dataForm) {
if (dataForm == null) {
return new ResponseEntity(HttpStatus.BAD_REQUEST);
}
locationRepository.save(new Location(dataForm.getName()));
return new ResponseEntity(HttpStatus.CREATED);
}
#RequestMapping(value = "/api/roles", method = RequestMethod.POST)
public ResponseEntity addRole(#RequestBody DataForm dataForm) {
if (dataForm == null) {
return new ResponseEntity(HttpStatus.BAD_REQUEST);
}
roleRepository.save(new Role(dataForm.getName()));
return new ResponseEntity(HttpStatus.CREATED);
}
#RequestMapping(value = "/api/departments", method = RequestMethod.POST)
public ResponseEntity addDepartment(#RequestBody DataForm dataForm) {
if (dataForm == null) {
return new ResponseEntity(HttpStatus.BAD_REQUEST);
}
departmentRepository.save(new Department(dataForm.getName()));
return new ResponseEntity(HttpStatus.CREATED);
}
}
This should happen only if the id would be static, but It's not. If I create two new Location() objects, when I will create a new Department() the Id of the department will be 3. Why ?

Since you didn't specify the strategy for #GeneratedValue, I guess that Hibernate uses the same sequence for all your entities.
You can set something like
#Id
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="department_seq_gen")
#SequenceGenerator(name="department_seq_gen", sequenceName="DEPARTMENT_SEQ")
on Department entity, and something similar on Location entity (just use location_seq_gen and LOCATION_SEQ).

Spring JPA Hibernate ManyToMany

i'm using SpringBoot, with Spring JPA Hibernate, i'm trying to use the ManyToMany Annotation but it isn't working.
The join table is created, but never populated.
#Entity
#Table(name = "commande")
public class Commande {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer commandeID;
private String etat;
private String date_de_validation;
#ManyToOne(cascade = CascadeType.ALL)
private Client clientID;
#ManyToOne(cascade = CascadeType.ALL)
private Livreur livreurID;
#ManyToOne(cascade = CascadeType.ALL)
private Livraison livraisonID;
#ManyToMany
#JoinTable(name = "Join_Produit_To_Commande", joinColumns = { #JoinColumn(name = "commandeID") }, inverseJoinColumns = { #JoinColumn(name = "produitID") })
private Set<Produit> produits = new HashSet<Produit>();;
public Commande() {
}
public Commande(String etat, String date_de_validation, Client clientID,
Livreur livreurID, Livraison livraisonID) {
setEtat(etat);
setDate_de_validation(date_de_validation);
setClient(clientID);
setLivreur(livreurID);
setLivraison(livraisonID);
}
public Integer getCommandeID() {
return this.commandeID;
}
public void setCommandeID(Integer commandeID) {
this.commandeID = commandeID;
}
public String getEtat() {
return this.etat;
}
public void setEtat(String etat) {
this.etat = etat;
}
public String getDate_de_validation() {
return this.date_de_validation;
}
public void setDate_de_validation(String date_de_validation) {
this.date_de_validation = date_de_validation;
}
public Client getClient() {
return this.clientID;
}
public void setClient(Client clientID) {
this.clientID = clientID;
}
public Livreur getLivreur() {
return this.livreurID;
}
public void setLivreur(Livreur livreurID) {
this.livreurID = livreurID;
}
public Livraison getLivraison() {
return this.livraisonID;
}
public void setLivraison(Livraison livraisonID) {
this.livraisonID = livraisonID;
}
public Client getClientID() {
return clientID;
}
public void setClientID(Client clientID) {
this.clientID = clientID;
}
public Livreur getLivreurID() {
return livreurID;
}
public void setLivreurID(Livreur livreurID) {
this.livreurID = livreurID;
}
public Livraison getLivraisonID() {
return livraisonID;
}
public void setLivraisonID(Livraison livraisonID) {
this.livraisonID = livraisonID;
}
public Collection<Produit> getProduits() {
return produits;
}
public void setProduits(Set<Produit> produits) {
this.produits = produits;
}
public String toString() {
return "commandeID=" + commandeID + " etat=" + etat
+ " date_de_validation=" + date_de_validation + " clientID="
+ clientID + " livreurID=" + livreurID + " livraisonID="
+ livraisonID;
}
}
This is my second class
#Entity
#Table(name = "produit")
public class Produit {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer produitID;
private String libelle;
private double poid;
private String type;
#ManyToMany(mappedBy = "produits")
private Set<Commande> commandes = new HashSet<Commande>();;
public Produit() {
}
public Produit(String libelle, double poid, String type) {
setLibelle(libelle);
setPoid(poid);
setType(type);
}
public String getLibelle() {
return this.libelle;
}
public void setLibelle(String Libelle) {
this.libelle = Libelle;
}
public double getPoid() {
return this.poid;
}
public void setPoid(double poid) {
this.poid = poid;
}
public String getType() {
return this.type;
}
public void setType(String type) {
this.type = type;
}
public Set<Commande> getCommandes() {
return commandes;
}
public void setCommandes(Set<Commande> commandes) {
this.commandes = commandes;
}
public String toString() {
return "Libelle=" + libelle + " poid=" + poid + " type=" + type
+ " produitID=" + produitID + " Commandes : " + commandes;
}
}
And here my Unit testing
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = PfeApplication.class)
#WebAppConfiguration
#Transactional
#TransactionConfiguration(defaultRollback = true)
public class PfeApplicationTests {
#Autowired
private EntrepriseService service;
#Autowired
private PhoneService pService;
#Autowired
private LivreurService lService;
#Autowired
private CarService cService;
#Autowired
private ProduitService prService;
#Autowired
private ClientService clService;
#Autowired
private CommandeService cmdService;
#Autowired
private PositionLivreurService posService;
#Autowired
private LivraisonService livService;
#Test
public void contextLoads() {
}
#Test
#Transactional
public void manyToManyTest(){
Produit produit1 = new Produit("Lavabo", 50, "Cassable");
Livreur livreur1 = new Livreur("Adadi", "Soufiane", "03/03/1992", "0876543456");
Client client1 = new Client("Ouali", "Ouali#gmail.com", "0743453462", "Fes", "NoLogo");
Livraison livraison1 = new Livraison("24/04/2015", "25/04/2015", false, false, livreur1);
Commande commande1 = new Commande("Validé", "25/04/2015", client1, livreur1, livraison1);
produit1.getCommandes().add(commande1);
commande1.getProduits().add(produit1);
cmdService.addCommande(commande1);
prService.addProduit(produit1);
}
}

This problem similar to an earlier posting of mine. See My original posting. I solved it myself - it is basically a bug in the implementation, but if you just change Set<> into List<>, it could maybe work. Your case is different, you are using a spring implementation, but who knows ...

Resolved !
I had to add them both on the same Session on a transaction and then commit.
