Hibernate JPA - Wrongly generated insert statement

Hibernate is generating wrong insert statement - wrong column binding - for the following entity model with single table inheritance and composite primary key using #IdClass.
Wondering if this is a Hibernate bug.
Stack: Spring Boot 2.7 / H2
Superclass base entity - AbstractMemberEvent:
#Entity
#Table(name = "MEMBER_EVENTS")
#Getter
#FieldDefaults(level = AccessLevel.PRIVATE)
#Inheritance(strategy = InheritanceType.SINGLE_TABLE)
#DiscriminatorColumn(name = "EVENT_TYPE")
#NoArgsConstructor
#IdClass(MemberEventId.class)
public abstract class AbstractMemberEvent {
#Id
#Column(name = "USID")
String usid;
#Id
#Column(name = "UPDATED")
Long eventTime;
#Id
#Column(name = "EVENT_TYPE", insertable = false, updatable = false )
String eventType;
Subclass entity - NewMemberJoined
#Entity
#Getter
#Setter
#FieldDefaults(level = AccessLevel.PRIVATE)
#DiscriminatorValue("NEWMEMBERJOINED")
#NoArgsConstructor
public class NewMemberJoined extends AbstractMemberEvent{
#Column(name="PAYLOAD")
NewMemberJoinedInfo newMemberJoinedInfo;
The IdClass
#Getter
#FieldDefaults(level = AccessLevel.PRIVATE)
#NoArgsConstructor
#EqualsAndHashCode
public class MemberEventId implements Serializable {
String usid;
Long eventTime;
String eventType;
}
From the logs I see that the wrong values are bound to the parameters
Hibernate:
create table member_events (
event_type varchar(31) not null,
updated bigint not null,
usid varchar(255) not null,
payload varchar(255),
primary key (updated, event_type, usid)
)
...
Hibernate:
insert
into
member_events
(payload, event_type, updated, usid)
values
(?, ?, ?, ?)

Error of "Duplicate entry '14' for key 'dishes.PRIMARY'" When saving a value in DB via Json file

I have a problem saving a row in the "Orders" table. Each order includes a list of dishes.
When I saved through the code everything was fine. But when I send a JSON file, I see that Spring sends an update command to the DISH table. And I do not understand why, how can he be made not to update the value obtained?
this is the orders class:
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
#Entity
#Table(name="Orders")
public class Orders {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int orderId;
#Column(name="customer_name")
private String customerName;
#ElementCollection
#ManyToMany(mappedBy ="Orders",cascade = CascadeType.MERGE)
#JoinColumn(name = "id")
private List<Dish> dish;
#Column(name="order_date")
private Date orderDate;
#Enumerated(value = EnumType.ORDINAL)
#Column(name = "status_id")
private Status status;
#Enumerated(value = EnumType.ORDINAL)
#Column(name = "table_id")
private RTable table;
#ManyToOne
#JoinColumn(name = "waiter_id")
private Waiter waiter;
#Column(name="total_price")
private double totalPrice;
The Dish class:
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
#Entity
#Table(name="dishes")
public class Dish{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String name;
#Column(name="preperation_Time_By_Minutes")
private double preperationTimeByMinutes;
private double price;
}
part from the trace: (including the unwanted update query)
Hibernate: insert into orders (customer_name, order_date, status_id, table_id, total_price, waiter_id) values (?, ?, ?, ?, ?, ?)

JPA #MapsId inserts 0 instead of correct value

I have these entities (unnecessary columns removed for brevity)
Order
#Entity
#Table(name = "orders")
public class Order {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#OneToOne(mappedBy = "order", cascade = CascadeType.ALL, optional = false)
private Shipment shipment;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Shipment getShipment() {
return shipment;
}
public void setShipment(Shipment shipment) {
this.shipment = shipment;
this.shipment.setOrder(this);
}
}
Shipment
#Entity
#Table(name = "shipments")
public class Shipment {
#Id
#Column(name = "order_id")
private int id;
#OneToOne
#MapsId
private Order order;
#OneToOne(mappedBy = "shipment", cascade = CascadeType.ALL, optional = false)
private ShippingAddress shippingAddress;
public Order getOrder() {
return order;
}
public void setOrder(Order order) {
this.order = order;
}
public ShippingAddress getShippingAddress() {
return shippingAddress;
}
public void setShippingAddress(ShippingAddress shippingAddress) {
this.shippingAddress = shippingAddress;
this.shippingAddress.setShipment(this);
}
}
ShippingAddress
#Entity
#Table(name = "shipping_address")
public class ShippingAddress {
#Id
#Column(name = "shipment_id")
private int id;
#OneToOne
#MapsId("shipment_id")
private Shipment shipment;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Shipment getShipment() {
return shipment;
}
public void setShipment(Shipment shipment) {
this.shipment = shipment;
}
}
The problem arises when I attempt to save a new Order. As you can see from the logs, Hibernate correctly sets the values to the Order and Shipment entities but assigns 0 to the shipment_id column in shipping_address, which of course causes a FK conflict.
I believe I'm using #MapsId correctly, because like I said, it works for the Order and Shipment relationship, but it doesn't seem to work for the Shipment and ShippingAddress.
These are the logs

As you can see on the last insert, Hibernate attempts to insert a 0 instead of the shipment_id.
Is there something I'm missing?

According to the documentation the value of the #MapsId annotation is referred to the name of the attribute within the composite key to which the relationship attribute corresponds. You do not use composite key.
So, this:
#OneToOne
#MapsId("shipment_id")
private Shipment shipment;
should be corrected to this:
#OneToOne
#MapsId
#JoinColumn(name = "shipment_id")
private Shipment shipment;
I can not find proof in the documentation, but hibernate ignore #Column(name = "shipment_id") on #Id when you use #MapsId, so you should specify PK column name of the ShippingAddress by adding #JoinColumn.

HttpMessageNotWritableException: Could not write JSON: Could not initialize proxy AFTER adding data into DB

Here's my question. I am unable to write the JSON after I send a POST request from POSTMAN to create/add a row into my SQL database. I need the server to send back a response of the added entry in order to retrieve the ID that SQL generates.
I face this issue when the new Case entry is a child of two entities(User and Application) and a grandchild of one entity(Owner).
*User(Owner)
|\
| *Application
|/
*Case
I'm new and currently using the Spring Boot JPA package.
I'm aware that many have asked questions related to the error above. There is none regarding my case to my knowledge. All of them refer to fixes over a HTTP GET method. If you found some please guide me to them. Or please help to answer my query. Any help is appreciated!

There are as many problems with your code as i really don't know how to help to solve it.
but as a quick fix try to create a new entity class for user object.

Solved it with this workaround.
Since fooService.save(foo); also updates the foo object with the ID, I can simply return foo.getId() to achieve what I want without sending another find method.
i.e. Case Service
public Integer updateCase(Case aCase) {
caseRepository.save(aCase);
return aCase.getId();
}

How to update an item in one to many relationship

I am trying to update a one to many relationship but getting a
insert into sw_standard_standard (sw_standard_id, standard_id) values
(?, ?) [23505-192]]; nested exception is
org.hibernate.exception.ConstraintViolationException
Here is my code:
SwStandard
#Entity
public class SwStandard implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.TABLE)
private Long id;
#OneToOne
private DeviceType deviceType;
#ElementCollection
#OneToMany
private List<Image> standard;
#ElementCollection
#OneToMany
private List<Image> limited;
#ElementCollection
#OneToMany
private List<Image> exception;
public SwStandard() {}
public SwStandard(DeviceType deviceType, List<Image> standard, List<Image> limited, List<Image> exception) {
this.deviceType = deviceType;
this.standard = standard;
this.limited = limited;
this.exception = exception;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public DeviceType getDeviceType() {
return deviceType;
}
public void setDeviceType(DeviceType deviceType) {
this.deviceType = deviceType;
}
public List<Image> getStandard() {
return standard;
}
public void setStandard(List<Image> standard) {
this.standard = standard;
}
public List<Image> getLimited() {
return limited;
}
public void setLimited(List<Image> limited) {
this.limited = limited;
}
public List<Image> getException() {
return exception;
}
public void setException(List<Image> exception) {
this.exception = exception;
}
}
Image
#Entity
public class Image implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.TABLE)
private Long id;
private String name;
public Image() {}
public Image(String name) {
this.name = name;
}
public Image(Long id, String name) {
this.id = id;
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Update code:
#RequestMapping(value = "/swstandard/update", method = RequestMethod.POST)
public SwStandard updateSwStandard(#RequestBody SwStandard request) {
return swService.save(request);
}
SwService:
#Autowired
private SwStandardRepository swService;
SwStandardRepository:
public interface SwStandardRepository extends CrudRepository<SwStandard, Long> {
SwStandard findByDeviceTypeId(Long id);
}
First I save a SwStandard with 1 standard item. Then I save want to replace the standard item with something else. When I do this it returns the error above.
Edit
Alan Hay help partially helped.
Now I cannot save the same image across a SwStandard for example here is a SwStandard I'll save:
{
"id": 1,
"deviceType": { "id": 1 },
"standard": [{"id": 1}],
"limited": [],
"exception": []
}
and here is another SwStandard I'll save which will fail with the error above:
{
"id": 2,
"deviceType": { "id": 2 },
"standard": [{"id": 1}],
"limited": [],
"exception": []
}
As you can see both SwStandards have the same standard item.
Here is the log output:
