Im using Spring Boot as API Rest with VueJs on the frontend.
My models classes are:
#EqualsAndHashCode(callSuper = true)
#Entity
#Data
public class Habitante extends Persona {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
#NotBlank
#Pattern(regexp = "^[HM]$")
private String sexo;
#NotBlank
private String nacionalidad;
#Valid
#ManyToOne
#JsonIdentityReference(alwaysAsId = true)
private Vivienda Vivienda;
#Valid
#ManyToOne
#JsonIdentityReference(alwaysAsId = true)
private Identificacion tarjetaIdentificacion;
#Column(unique = true)
private String identificacion;
}
and
#Entity
#Data
#AllArgsConstructor
#NoArgsConstructor
public class Solicitud implements Serializable {
private static final long serialVersionUID = 9178661439383356177L;
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
#Past
private Date fecha;
#Valid
#ManyToOne
private Habitante solicitante;
private String justificacion;
#Pattern(regexp = "^[AM]$")
#NotBlank
private String tipo;
#Pattern(regexp = "^(ACR|AIM|MV|MD|MRE)$")
#NotBlank
private String subtipo;
// El estado puede ser pendiente (P), aceptada (A), rechazada (R) y cancelada (C)
#NotBlank
#Pattern(regexp = "^[ACRP]$")
private String estado;
// Sólo para menores de edad que lo quieran añadir o para personas con tarjeta identificativa
#Pattern(regexp = "^(\\d{8}\\w)|(\\d{7}[XYZ])$")
private String identificacion;
#Valid
#ManyToOne
private Identificacion tipoIdentificacion;
private String nombre;
private String primerApellido;
private String segundoApellido;
#Valid
#ManyToOne
private Vivienda vivienda;
#Past
private Date fechaNacimiento;
#Valid
#OneToMany
private List<Documento> documentos;
}
When I tried to send a new Solicitud using axios like this:
const solicitud = {
fecha: new Date(),
solicitante: {
id: props.userLogged.id
},
estado: 'P',
justificacion: '',
tipo: opcion.value,
subtipo: subOpcion.value,
nombre: nombre.value,
primerApellido: primerApellido.value,
segundoApellido: segundoApellido.value,
fechaNacimiento: fechaNacimiento.value,
tipoIdentificacion: { id: tipoIdentificacion },
// identificacion: tIdentificacion,
documentos: [],
};
await axios.post(`${BASE_URL}solicitud/habitante/new`, solicitud);
#PostMapping(value = "/habitante/new")
public Respuesta nuevaSolicitud(#RequestBody Solicitud solicitud){ ... }
On Spring, I dont get the entire Habitanteobject, only the id, the same thing happens with the property vivienda on another request, I get this:
Is there anyway to get the entire object on the controller?

I'm trying to make a existsBy query using a property that comes from an embedded class, but I'm receiving "No property 'cpf' found for type 'Patient'".
The class Patient uses the Person class as embedded.
Person.java
#Embeddable
#Data
public class Person {
#Column(nullable = false, length = 11)
private String cpf;
#Column(name = "full_name", nullable = false, length = 60)
private String fullName;
#Column(nullable = false)
private String birthdate;
#Column(name = "email", nullable = true, length = 30)
private String emailAddress;
#Column(name = "cellphone_number", nullable = true, length = 11)
private String cellphoneNumber;
}
Patient.java
#Data
#Entity
#Table(name = "tb_patient")
public class Patient implements Serializable {
#Serial
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "patient_id")
private UUID id;
#Column
private LocalDateTime registrationDate;
#Embedded
private Person Person;
}
PatientController.java (part of)
#PostMapping
public ResponseEntity<Object> savePatient(#RequestBody Person person) {
if(patientService.existsByCpf(person.getCpf())) {
return ResponseEntity.status(HttpStatus.CONFLICT).body("CONFLICT: CPF number is already in use!");
}
var patientModel = new Patient();
BeanUtils.copyProperties(person, patientModel);
patientModel.setRegistrationDate(LocalDateTime.now(ZoneId.of("UTC")));
return ResponseEntity.status(HttpStatus.CREATED).body(patientService.save(patientModel));
}
PatientService.java (part of)
#Service
public class PatientService {
final PatientRepository patientRepository;
public PatientService(PatientRepository patientRepository) {
this.patientRepository = patientRepository;
}
public boolean existsByCpf(String cpf) {
return patientRepository.existsByCpf((cpf));
}
PatientRepository.java
#Repository
public interface PatientRepository extends JpaRepository<Patient, UUID> {
boolean existsByCpf(String cpf);
}
How can I pass the #Embedded properties to the #Repository?
You can try separate by _ embedded filed name and it's filed.
#Repository
public interface PatientRepository extends JpaRepository<Patient, UUID> {
boolean existsByPerson_Cpf(String cpf);
}
I am new to Hibernate and JPA. I have several entities, each of which contains following four columns:
1. created_by
2. last_modified_by
3. created_date
4. last_modified_date
I would like these columns to get auto-populated while saving the associated entity.
Two sample entities are as follows:
Entity 1:
#Entity
#Table(name = "my_entity1")
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class MyEntity1 implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "name")
private String name;
#Column(name = "created_by")
private String createdBy;
#Column(name = "last_modified_by")
private String lastModifiedBy;
#Column(name = "created_date")
private Instant createdDate;
#Column(name = "last_modified_date")
private String lastModifiedDate;
}
Entity 2:
#Entity
#Table(name = "my_entity2")
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class MyEntity2 implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "description")
private String description;
#Column(name = "created_by")
private String createdBy;
#Column(name = "last_modified_by")
private String lastModifiedBy;
#Column(name = "created_date")
private Instant createdDate;
#Column(name = "last_modified_date")
private String lastModifiedDate;
}
In this context, I have gone through following posts: How to autogenerate created or modified timestamp field?, How can you make a created_at column generate the creation date-time automatically like an ID automatically gets created?.
I am getting how to capture the dates fields but I cannot understand how to capture created_by and last_modified_by.
Auditing Author using AuditorAware and Spring Security...
To tell JPA about currently logged in user we will need to provide an
implementation of AuditorAware and override getCurrentAuditor()
method. And inside getCurrentAuditor() we will need to fetch currently
logged in user.
Like this:
public class AuditorAwareImpl implements AuditorAware<String> {
#Override
public String getCurrentAuditor() {
return "TestUser";
// Can use Spring Security to return currently logged in user
// return ((User) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getUsername()
}
}
Now enable jpa auditing by using #EnableJpaAuditing
#Configuration
#EnableJpaAuditing(auditorAwareRef = "auditorAware")
public class JpaConfig {
#Bean
public AuditorAware<String> auditorAware() {
return new AuditorAwareImpl();
}
}
Look at this to get more details....
I want to persist an object like this one :
{
"paymentMode": "CREDIT CARD",
"totalAmount": 158.0,
"orderProducts": [
{
"productKeyId": "HycaR7sPeecIMZEewanuK0jzPo7S33",
"name": "Cornish crab salad, brown crab mayonnaise, toasted muffin",
"price": 20.0,
"qty": 1,
"imgPath": "pathImage",
"category": {
"categoryKeyId": "23ume70Fu6yqyGUWfQkW110P4ko3gZ",
"name": "Starter"
}
},...
],
"seller": {
"userKeyId": "qmNR5g2TD8Ja5KvA1DCQWzYj55nvbP",
"firstName": "David",
"lastName": "Vera",
"email": "david.vera#9online.fr",
"addresses": [
{
"addressKeyId": "2t7x0bFgP5B9Qb2ymnLL5aPZVwMFhJ",
"city": "Vancouver",
"country": "Canada",
"streetName": "123 street name",
"postalCode": "ABCCBA",
"type": "billing",
},...
]
},
"createdAt": "2019-10-22T09:48:06.000+0000"
}
Some object are already stored in Database such as seller, addresses, products and product category.
I created : Orders tables
#Entity
#Table(name="orders")
#Getter #Setter
public class OrderEntity implements Serializable {
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy= GenerationType.IDENTITY)
private Long id;
#Column(nullable = false, unique = true)
private String orderKeyId;
// A sale belong to one seller
#ManyToOne(fetch = FetchType.LAZY)
private UserEntity seller;
private String paymentMode;
private double totalAmount;
#OneToMany(mappedBy = "pk.order")
#Valid
private List<OrderProductEntity> orderProducts;
}
An order_product table (pivot table):
#Entity
#Table(name="order_product")
#Getter #Setter
public class OrderProductEntity {
#EmbeddedId
#JsonIgnore
private OrderProductPK pk;
#Column(nullable = false)
private Integer qty;
// default constructor
public OrderProductEntity() {
super();
}
public OrderProductEntity(OrderEntity order, ProductEntity product, Integer quantity) {
pk = new OrderProductPK();
pk.setOrder(order);
pk.setProduct(product);
this.qty = quantity;
}
#Transient
public ProductEntity getProduct() {
return this.pk.getProduct();
}
...
}
And a product table
#Entity
#Table(name="products")
#Getter #Setter
public class ProductEntity implements Serializable {
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy= GenerationType.IDENTITY)
private Long id;
#Column(nullable = false)
private String productKeyId;
// many to one relationship with category
#ManyToOne
#JoinColumn(name = "category_id")
private CategoryEntity category;
#Column(nullable = false)
private String name;
#Column(nullable = false)
private double price;
#Column(nullable = false)
private int qty;
private String imgPath;
#JsonManagedReference
#OneToMany(mappedBy = "pk.product", fetch = FetchType.EAGER)
#Valid
private List<OrderProductEntity> orderProducts;
}
The userEntity class :
#Entity
#Table(name = "users")
#Getter #Setter
public class UserEntity implements Serializable {
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy= GenerationType.IDENTITY)
private Long id;
#Column(nullable = false, unique = true)
private String userKeyId;
#Column(nullable = false, length = 50)
private String firstName;
#Column(nullable = false, length = 50)
private String lastName;
#Column(nullable = false, length = 120, unique = true)
private String email;
#Column(nullable = false)
private String encryptedPassword;
private String emailVerificationToken;
// column definition do not work for all database engine. So set the value to false is the same
// #Column(nullable = false, columnDefinition = "boolean default false")
#Column(nullable = false)
private Boolean emailVerificationStatus = false;
// One user can have Many Addresses
#OneToMany(mappedBy = "userDetails", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
#JsonManagedReference
private List<AddressEntity> addresses;
}
And finally the embedded class :
#Embeddable
#Getter #Setter
#ToString
public class OrderProductPK implements Serializable {
private static final long serialVersionUID = 476151177562655457L;
#ManyToOne(optional = false, fetch = FetchType.LAZY)
#JoinColumn(name = "order_id")
private OrderEntity order;
#ManyToOne(optional = false, fetch = FetchType.LAZY)
#JoinColumn(name = "product_id")
private ProductEntity product;
...
}
I created a controller method to persist orders in a MySQL database:
public OrderRest createOrder(#RequestBody OrderRequestModel orderRequestModel) throws Exception {
OrderRest returnValue = new OrderRest();
ModelMapper modelMapper = new ModelMapper();
OrderDto orderDto = modelMapper.map(orderRequestModel, OrderDto.class);
OrderDto createdOrder = orderService.createOrder(orderDto);
returnValue = modelMapper.map(createdOrder, OrderRest.class);
// 5. Return the expected object
return returnValue;
}
I have an orderDTO object that contains several fields (including ID).
public class OrderDto implements Serializable {
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
private Long id;
private String orderKeyId;
private String paymentMode;
private double totalAmount;
private List<ProductDto> orderProducts;
private UserDto seller;
private Date createdAt;
}
My productDTO object
public class ProductDto implements Serializable {
// ommit this member and do not generate getter / setter
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
private Long id;
private String productKeyId;
private String name;
private double price;
private int qty;
private String imgPath;
private CategoryDto category = new CategoryDto();
}
The UserDto :
#Getter #Setter
#ToString
public class UserDto implements Serializable {
// ommit this member and do not generate getter / setter
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
private long id;
private String userKeyId;
private String firstName;
private String lastName;
private String email;
private String password;
private String encryptedPassword;
private String emailVerificationToken;
private Boolean emailVerificationStatus = false;
private List<AddressDto> addresses;
// private List<RoleDto> roles;
}
the controller is calling my service layer :
#Override
public OrderDto createOrder(OrderDto orderDto) {
// create a new order
ModelMapper modelMapper = new ModelMapper();
OrderEntity orderEntity = modelMapper.map(orderDto, OrderEntity.class);
String orderKeyId = utils.generateOrderKeyId(30);
orderEntity.setOrderKeyId(orderKeyId);
orderEntity.setCreatedAt(orderDto.getCreatedAt());
orderEntity.setPaymentMode(orderDto.getPaymentMode());
orderEntity.setTotalAmount(orderDto.getTotalAmount());
// set the seller
UserEntity userEntity = modelMapper.map(orderDto.getSeller(), UserEntity.class);
orderEntity.setSeller(userEntity);
List<OrderProductEntity> orderProductEntities = new ArrayList<>();
// set the products
for (int i = 0; i < orderDto.getOrderProducts().size(); i++) {
ProductDto productDto = orderDto.getOrderProducts().get(i);
OrderProductEntity orderProductEntity = modelMapper.map(orderDto.getOrderProducts().get(i), OrderProductEntity.class);
orderProductEntities.add(orderProductEntity);
orderDto.getOrderProducts().set(i, productDto);
}
orderEntity.setOrderProducts(orderProductEntities);
OrderEntity storedOrder = orderRepository.save(orderEntity);
OrderDto returnValue = modelMapper.map(storedOrder, OrderDto.class);
return returnValue;
}
I have 3 issues :
I save the order in the database but the seller is not persisted
In the order product table datas are not persisted.
And i obtain an error message in my rest response :
"trace": "org.modelmapper.MappingException: ModelMapper mapping errors: Converter org.modelmapper.internal.converter.CollectionConverter#685b36d6 failed to convert java.util.List to java.util.List.error...
I have a Post entity
#Entity
public class Post {
#Id
private UUID id;
#NotNull
private String title;
#NotNull
private String content;
#NotNull
private String identifier;
#NotNull
private String category;
#NotNull
#Column(name = "created_at")
private Date createdAt;
#NotNull
#Column(name = "updated_at")
private Date updatedAt;
public Post (){
}
public Post (String title, String content, String category){
this.title = title;
this.content = content;
this.category = category;
}
// rest of the getters and setters
}
And this is my Comment entity:
#Entity
public class Comment {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private UUID id;
#NotNull
private String name;
#NotNull
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer identifier;
#NotNull
private String email;
#NotNull
private String content;
#NotNull
#ManyToOne
#JoinColumn(name = "post_id")
private Post postId;
#NotNull
#Column(name = "created_at")
private Date createdAt;
public Comment() {
}
public Comment(String name, String email, String content){
this.name = name;
this.email = email;
this.content = content;
}
}
And this is my post controller:
#RestController
#RequestMapping("/posts")
public class PostController {
private String getIdentifier(String str){
return String.join("-", str.split(" "));
}
#Autowired
private PostService postService;
#RequestMapping(value = "", method = {GET, HEAD})
public List<Post> getAllPosts(){
return postService.getAllPosts();
}
#RequestMapping(value = "", method = {POST, OPTIONS})
public Post addNewPost(#RequestBody Post post){
post.setId(UUID.randomUUID());
post.setIdentifier(this.getIdentifier(post.getTitle()));
post.setCreatedAt(new Date());
post.setUpdatedAt(new Date());
return postService.savePost(post);
}
#RequestMapping(value = "/{id}", method = {GET, HEAD})
public Post getOnePost(#PathVariable UUID id){
return postService.getOne(id);
}
#RequestMapping(value = "/{id}", method = DELETE)
public void deleteOnePost(#PathVariable UUID id){
postService.deleteOnePost(id);
}
}
My question is how do I fetch all the comments for each individual post, whenever I fetch all the posts?
Sorry, I come from a NoSQL background, so this is a bit daunting at first.
What you need to do is to create a bidirectional #OneToMany association from the Post to Comments:
add a field in Post class
#OneToMany(
mappedBy = "postId",
cascade = CascadeType.ALL
)
private List<Comments> comments = new ArrayList<>();
From now on, when you get Post from the database, Comments will be fetched at the same time.
I am unable to extract the current logged in user in Spring Security OAuth2. My goal is to extract the user when the create event on ClientSuggestion entity is triggered and persist it to the database.
Employee.java

cs.setActive(true);
cs.setPasswordResetToken(Encryptor.generateHash(cs.getPassword, 512));
cs.setEmployee(employee);
}
}
The bean, ClientSuggestionEventHandler, is registered in a configuration class. When I tried running the project, NullPointerException exception is thrown. I wish to find out how to get the current logged employee.
I'm new to Spring Security OAuth2. Thanks.
In Employee.java implement org.springframework.security.core.userdetails.UserDetails class
Employee.java
#Entity
#Table(name = "er_employee")
public class Employee implements Serializable, UserDetails {
And then use Employee employee= (Employee) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
