I have these entities
#Entity(name = "inspiration")
class InspirationEntity(
#Id
var uuid: UUID? = null,
#Column(name = "display_name")
var displayName: String,
#CreationTimestamp
#Column(name = "created_at")

#Entity(name = "base_slider")
#Inheritance(strategy = InheritanceType.JOINED)
//TODO investigate DiscriminatorColumn anotation and best practices, because it shows some warning in logs
#DiscriminatorColumn(name = "slider_type", discriminatorType = DiscriminatorType.STRING)
abstract class BaseSliderEntity(

#GeneratedValue(strategy = GenerationType.IDENTITY)
open var id: Long? = null,

#Entity(name = "dish_of_the_day")
#DiscriminatorValue("DISH_OF_THE_DAY")
class DishOfTheDayEntity(
#Column(name = "title_en")
var titleEN: String,

var titleDE: String,
) : BaseSliderEntity()
#Entity(name = "inspiration_screen_link")
#DiscriminatorValue("LINK")
class InspirationScreenLinkEntity(
#Enumerated(EnumType.STRING)
var destination: Destination,

this is my dto
data class InspirationDTO(
#JsonProperty(access = JsonProperty.Access.READ_ONLY)
var uuid: UUID?,
#JsonProperty(access = JsonProperty.Access.READ_ONLY)
var createdAt: Date?,
#JsonProperty(access = JsonProperty.Access.READ_ONLY)
var lastModifiedDate: Date?,
val displayName: String,
val inspirationScreenItemList: List<InspirationScreenItemDTO>,
)
and this is InspirationScreenItemDTO
#JsonTypeInfo(use = JsonTypeInfo.Id.NAME, property = "type")
#JsonSubTypes(
JsonSubTypes.Type(value = DishOfTheDayDTO::class, name = "DishOfTheDay"),
JsonSubTypes.Type(value = InspirationScreenContinuousSliderDTO::class, name = "InspirationScreenContinuousSlider"),
JsonSubTypes.Type(value = InspirationScreenLinkDTO::class, name = "InspirationScreenLink"),
JsonSubTypes.Type(value = InspirationScreenPagingSliderDTO::class, name = "InspirationScreenPagingSlider"),
JsonSubTypes.Type(
value = InspirationScreenRecentlyViewedSliderDTO::class,
name = "InspirationScreenRecentlyViewedSlider"
),
JsonSubTypes.Type(value = InspirationScreenTagsSliderDTO::class, name = "InspirationScreenTagsSlider"),
)
open class InspirationScreenItemDTO
when I try to update
like this
#Transactional
fun update(uuid: UUID, inspirationDTO: InspirationDTO): InspirationDTO {
var entity = inspirationRepository.findById(id).get()
val updatedEntity: InspirationEntity = inspirationMapper.convertToEntity(inspirationDTO)
entity.sliderList = updatedEntity.sliderList
val result: InspirationEntity = inspirationRepository.save(entity)
return inspirationMapper.convertToDto(result)
}
this is my swagger post
{
"displayName": "ED",
"inspirationScreenItemList": [
{
"type": "DishOfTheDay",
"titleEN": "GGGGGGG",
"titleDE": "GGGGGGG"
}
]
}
in DishofDto table it creates two rows first and updated, and inspiration remains one row which is okay but dish of the day shouldn't contain two rows, it should be just updated one.
My solution was to add uuid id as primary key in inspiration which works with deleting by id and then put toUpdateDto under the same id and save , but I'm not sure it's good solution.

I am trying to simply test a repository. Here is my test code:
#ContextConfiguration(classes = [
DatabaseTestConfiguration::class
])
#TestPropertySource(
properties = [
"spring.jpa.hibernate.ddl-auto=create-drop",
"spring.flyway.enabled=false"
]
)
#AutoConfigureTestDatabase
#AutoConfigureDataJpa
#AutoConfigureTestEntityManager
internal open class UserTest {
#Autowired
private lateinit var entityManager: TestEntityManager
#Autowired
private lateinit var userRepository: UserRepository
#Test
#Transactional
open fun whenSuccessfullyFoundAnyDuplicatedUserThenReturnTrue() {
val user = User()
user.name = NAME
user.surname = SURNAME
user.gender = GENDER
entityManager.persistAndFlush(user)
assertEquals(true, userRepository.anyDuplicate(
name = user.name,
surname = user.surname,
gender = user.gender,
))
}
companion object {
const val NAME = "John"
const val SURNAME = "Snow"
const val GENDER = "male"
}
Here is my DatabaseTestConfiguration:
#TestConfiguration
#EntityScan(value = [
"com.username.db.entities"
])
#EnableJpaRepositories(
"com.username.db.repositories"
)
class DatabaseTestConfiguration {
}
This is my repository:
#Repository
interface UserRepository: JpaRepository<User,Long> {
#Query(
"""
SELECT CASE
WHEN COUNT(user.id) > 0 THEN TRUE
ELSE FALSE END
FROM User user
WHERE user.name = :name AND user.surname = :surname AND user.gender = :gender
)
"""
)
fun anyDuplicate(
#Param("name") name: String?,
#Param("surname") surname: String?,
#Param("gender") gender: String?
): Boolean
}
This is my entity:
#Entity
#Table(name = "user")
class User {
#Id
#GeneratedValue(
strategy = GenerationType.SEQUENCE,
generator = "cdr_generator"
)
#SequenceGenerator(
name = "cdr_generator",
sequenceName = "cdr_seq",
allocationSize = 1
)
#Column(name = "id", nullable = false)
var id: Long? = null
#Column(name = "name", nullable = false)
var name: String? = null
#Column(name = "surname", nullable = false)
var surname: String? = null
#Column(name = "gender", nullable = false)
var gender: String? = null
}
Now when i am testing. this will always fail my test. When i debug it, i get that in my test it never enters userRepository.anyDuplicate() function. I assume that the problem is with configuring test. Can anybody help?
I trying to get two fields and a #ElementCollection from entity using projection with interface, but the JPA are selecting all fields from my entity and when i remove the method that get the list of my #ElementCollection the JPA select the only two fields.
My entity class:

Hibernate: select authoriti0_.user_id as user_id1_8_0_, authoriti0_.authority as authorit2_8_0_ from profiles_authorties authoriti0_ where authoriti0_.user_id=?
when i remove fun getAuthorities(): Set<ProfileAuthorities> from LoginUserProjection the result is:
Hibernate: select user0_.id as col_0_0_, user0_.password_hash as col_1_0_ from users user0_ where user0_.id=?

I am creating a simple kanban application as following, each kanban is made out of a sequence of stages and each stage have a level field to define its position. I want to be able to add, move and remove stages at will so I have to keep the level of each stage consistent, simple enough.
#Entity
#Table(name = "kanbans")
data class Kanban (
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false)
var id: Int? = null,
#get:NotNull
#get:NotBlank
#Column(name = "name", nullable = false)
var name: String? = null,
#get:NotNull
#get:NotBlank
#Column(name = "description", nullable = false)
var description: String? = null,
#get:NotNull
#Column(name = "closed", nullable = false)
var closed: Boolean? = null,
#get:NotNull
#Column(name = "created_at", nullable = false)
var createdAt: LocalDateTime? = null,
#get:NotNull
#Column(name = "updated_at", nullable = false)
var updatedAt: LocalDateTime? = null,
)
#Entity
#Table(name = "stages")
data class Stage (
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false)
var id: Int? = null,
#get:NotNull
#get:NotBlank
#Column(name = "name", nullable = false)
var name: String? = null,
#get:NotNull
#get:NotBlank
#Column(name = "description", nullable = false)
var description: String? = null,
#get:NotNull
#Column(name = "closed", nullable = false)
var closed: Boolean? = null,
#get:NotNull
#Column(name = "level", nullable = false)
var level: Int? = null,
#OneToMany(fetch = FetchType.LAZY, mappedBy = "stage")
var tasks: List<Task> = ArrayList(),
#get:NotNull
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "kanban_id", nullable = false)
var kanban: Kanban? = null,
#get:NotNull
#Column(name = "created_at", nullable = false)
var createdAt: LocalDateTime? = null,
#get:NotNull
#Column(name = "updated_at", nullable = false)
var updatedAt: LocalDateTime? = null,
)
When creating the first stage its always assigning its level at 0 and then when adding new ones the level will define the stage position at the list of stages. The problem is that when I try to update the previous existing stages to give place to the new one, the only way I found to make this work is to place a saveAndFlush call in a loop but I find it to be not a good ideia.
#Repository
interface StageRepository : JpaRepository<Stage, Int> {
fun findAllByKanbanAndLevelGreaterThanEqualOrderByLevelDesc(kanban: Kanban, level: Int): List<Stage>
#Modifying
#Transactional
#Query("UPDATE Stage s SET s.level = s.level + 1 WHERE s.kanban = :kanban AND s.level >= :level")
fun incrementLevelForKanbanStagesWhereLevelIsGreaterThan(kanban: Kanban, level: Int)
}
the incrementLevelForKanbanStagesWhereLevelIsGreaterThan method fails as the database have a unique constraint to level and kanban_id with the following error:
Caused by: org.postgresql.util.PSQLException: ERROR: duplicate key value violates unique constraint "stages_kanban_id_level_key"
Detalhe: Key (kanban_id, level)=(337, 1) already exists.
this is obviously happening because it is trying to update level 0 to level 1 before updating level 1 to level 2 and so I have tried:
#Transactional
#Query("UPDATE Stage s SET s.level = s.level + 1 WHERE s.kanban = :kanban AND s.level >= :level ORDER BY s.level DESC")
fun incrementLevelForKanbanStagesWhereLevelIsGreaterThan(kanban: Kanban, level: Int)
which does not compile,
#Service
#Transactional
class StageCrudService: CrudService<Stage, Int, StageRepository, StageValidationService>() {
#Throws(ValidationException::class)
override fun create(model: Stage): Stage {
prepareToCreate(model)
validationService.canSave(model)
incrementKanbanStageLevels(model)
return repository.save(model)
}
private fun prepareToCreate(model: Stage) {
val now = LocalDateTime.now()
val closed = model.closed ?: false
model.closed = closed
model.createdAt = now
model.updatedAt = now
model.level = model.level ?: 0
}
private fun incrementKanbanStageLevels(model: Stage) {
val level = model.level ?: 0
val stages = repository.findAllByKanbanAndLevelGreaterThanEqualOrderByLevelDesc(model.kanban!!, level)
stages.forEach { stage ->
stage.level = stage.level?.plus(1)
}
repository.saveAll(stages)
repository.flush()
}
}
and
private fun incrementKanbanStageLevels(model: Stage) {
val level = model.level ?: 0
val stages = repository.findAllByKanbanAndLevelGreaterThanEqualOrderByLevelDesc(model.kanban!!, level)
stages.forEach { stage ->
stage.level = stage.level?.plus(1)
repository.save(stage)
}
repository.flush()
}
but both fails the same way as the query. Now the question is:
Is there a better way to manage the update order for this kind of situation instead of doing:
private fun incrementKanbanStageLevels(model: Stage) {
val level = model.level ?: 0
val stages = repository.findAllByKanbanAndLevelGreaterThanEqualOrderByLevelDesc(model.kanban!!, level)
stages.forEach { stage ->
stage.level = stage.level?.plus(1)
repository.saveAndFlush(stage)
}
}
It seems to me that you are possibly trying to implement something that can be managed for you via the JPA #OrderColumn annotation:
https://docs.oracle.com/javaee/7/api/javax/persistence/OrderColumn.html
Specifies a column that is used to maintain the persistent order of a
list. The persistence provider is responsible for maintaining the
order upon retrieval and in the database. The persistence provider is
responsible for updating the ordering upon flushing to the database to
reflect any insertion, deletion, or reordering affecting the list.
To use this you would need to make the relationship bi-directional and the level should be maintained by your JPA provider as items are added to and removed from the list
#Entity
#Table(name = "kanbans")
data class Kanban (
.....
#get:NotNull
#get:NotBlank
#OrderColumn(name = "level")
#OneToMany(fetch = FetchType.LAZY, mappedBy = "kanban")
var stage: List<Stage> = ArrayList()
.....
}
So you can then remove and add items (at any position) and the sequence will be maintained for you.
Hibernate doesn't want to save IDs for child entities. I have the following tables:
#Entity
#Table(name = "ct_orders")
data class Order(
#Id
#Column(name = "id")
#GeneratedValue(strategy = javax.persistence.GenerationType.IDENTITY)
val id: Int = 0,
#OneToMany(fetch = FetchType.LAZY, cascade = arrayOf(CascadeType.ALL), mappedBy = "order")
val route: List<Route>? = null,
...
)
#Entity
#Table(name = "ct_routes")
#JsonIgnoreProperties("id", "order")
data class Route(
#Id
#Column(name = "id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
val id: Int = 0,
#Column
val location: Point = GeoHelpers.point(),
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "order_id")
val order: Order? = null,
#Column
val title: String = ""
)
ct_routes saving with null in order_id. Is there some problem with relationships? Or, may be there is something wrong in my code?
Here is the part of code, which saves an Order entity:
val order = orderRepository.save(Order(
...
route = GeoHelpers.placesListToEntities(data.places),
...
))
fun placesListToEntities(points: List<PlaceDto>) = points.map {
Route(
location = Helpers.geometry(it.location.latitude, it.location.longitude),
title = it.title
)
}
You're modeling bidirectional #OneToMany and as shown in the example in the documentation you're responsible for setting the parent value on the child entity:
val order = orderRepository.save(Order(...).apply{
...
route = GeoHelpers.placesListToEntities(this, data.places),
...
})
fun placesListToEntities(order:Order, points: List<PlaceDto>) = points.map {
Route(
order = order,
location = Helpers.geometry(it.location.latitude, it.location.longitude),
title = it.title
)
}
PS. Since Route is an entity you could change your model a bit to enforce the constraints on the langauge level i.e:
class Route internal constructor() {
lateinit var order: Order
constructor(order: Order) : this() {
this.order = order
}
}
See this question for more details.

When i try to refresh token (/oauth/token?grant_type=refresh_token&client_id=abc&client_secret=abcd&refresh_token=...), i got the following error message:
{
"error": "server_error",
"error_description": "java.io.NotSerializableException: org.geolatte.geom.jts.PointSequenceCoordinateSequenceFactory"
}
How can i fix it? And what is the cause of this problem?
Helpers.geometry func:
fun geometry(lat: Double, lng: Double): Point {
return GeometryFactory(PrecisionModel(), 4326).createPoint(Coordinate(lat, lng))
}
My fault. Problem was in my UserDetailsService,
