Unable to add value to entity

I can’t set the discipline values ​​​​for my semester, when I work out the controller, I get all the data I need, but I can’t connect them, can anyone tell me with an experienced eye what is the reason? I am getting this kind of error:

Request hibernate with #EmbeddedId not working (Spring boot - 2.3.1.RELEASE)

I'm blocked in my project. I can't get sql queries to work with the class that's "#Embeddable."

I have the class "Preference" which use two primary key : an user and a key (enum). So I use the annotation #EmbeddedId and declare PreferenceId.
package com.donation.rest.model;

#EmbeddedId
private PreferenceId preferenceId;
#Column(name = "PREFERENCE_VALUE", nullable = false)
#Type(type = "text")
private String value;
public Preference() {
super();
}
public Preference(PreferenceId preferenceId, String value) {
super();
this.preferenceId = preferenceId;
this.value = value;
}
public PreferenceId getPreferenceId() {
return preferenceId;
}
public void setPreferenceId(PreferenceId preferenceId) {
this.preferenceId = preferenceId;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
#Override
public String toString() {
return "Preference [preferenceId=" + preferenceId + ", value=" + value + "]";
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((preferenceId == null) ? 0 : preferenceId.hashCode());
result = prime * result + ((value == null) ? 0 : value.hashCode());
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Preference other = (Preference) obj;
if (preferenceId == null) {
if (other.preferenceId != null)
return false;
} else if (!preferenceId.equals(other.preferenceId))
return false;
if (value == null) {
if (other.value != null)
return false;
} else if (!value.equals(other.value))
return false;
return true;
}
}
Then, the class "PreferenceId" which is "#Embeddable".

private PreferencesEnum key;
public PreferenceId() {

public PreferenceId(User user, PreferencesEnum key) {

}
}
I have a controller which return a value of preference with user id and key parameter.
Controller
Next is the service. This is where my problems begin. I've tested a lot of calls from the jpa repository that I've commented on.
Service
Here the repository :
Repository
The preference I want to retrieve from the database is:
Preference key: LANGUAGE
Preference user id: 1
Preference value : fr
Now the request I used in postman :
Request
And here's the mistake with the request Hibernate made.
I don't get it. It duplicates the fields and also it doesn't use the embedded id field (it doesn't do "preference.preferenceId.user.userId" and "preference.preferenceId.key").
Error
What'd I miss? What did I do wrong? I've looked it all up on the internet, I've tested everything, I just can't do it...
Otherwise, I used "Embeddedid" instead of "IdClass" to avoid duplicating the getters and setters.
Thanks to you guys.

hibernate onetomany annotation fetch = FetchType.LAZY didn't work

I have three tables A,B and C. Table B has a foreign key a_id reference to table A, Table B has a foreign key a_id reference to table A. And my hibernate entity files are as following:
A.java
#Entity
#Table(name = "A")
public class A {
private long id;
private String contentA;
private List<B> bList;
private List<C> cList;
#OneToMany(fetch = FetchType.EAGER , mappedBy = "b")
public List<B> getbList() {
return bList;
}
public void setbList(List<B> bList) {
this.bList = bList;
}
#OneToMany(fetch = FetchType.EAGER , mappedBy = "b")
public List<C> getcList() {
return cList;
}
public void setcList(List<C> cList) {
this.cList = cList;
}
#Id
#Column(name = "id", nullable = false)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
#Basic
#Column(name = "content_a", nullable = false, length = 1000)
public String getContentA() {
return contentA;
}
public void setContentA(String contentA) {
this.contentA = contentA;
}
}
B.java
#Entity
#Table(name = "B")
public class B {
private long id;
private String contentB;
private A a;
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "a_id", nullable = false)
public A getA() {
return a;
}
public void setA(A a) {
this.a = a;
}
#Id
#Column(name = "id", nullable = false)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
#Basic
#Column(name = "content_b", nullable = false, length = 1000)
public String getContentB() {
return contentB;
}
public void setContentB(String contentB) {
this.contentB = contentB;
}
}
C.java
#Entity
#Table(name = "C")
public class C {
private long id;
private String contentC;
private A a;
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "a_id", nullable = false)
public A getA() {
return a;
}
public void setA(A a) {
this.a = a;
}
#Id
#Column(name = "id", nullable = false)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
#Basic
#Column(name = "content_c", nullable = false, length = 1000)
public String getContentC() {
return contentC;
}
public void setContentC(String contentC) {
this.contentC = contentC;
}
}
the problem is sometimes I just want to get A with List<B>, in another time I want to get A with List<C>. Is there any way I can do this by hibernate?

In my real project, I have three entity class: ChapterEntity ChapterTitle1Entity ChapterTitle2Entity ChapterTitle3Entity.

Change FetchType.EAGER to FetchType.LAZY in your #OneToMany annotations. This will casue Hibernate to load a collection only when you directly refer to it.

failed to lazily initialize a collection of role ManyToMany relation

I have an entity question and an entity test with ManyToMany relationship between the two entitie.
when I want to view the questions of a test this error is occurred.

When you get Test and access Test.questions later, after leaving the transaction, you will get a lazy initialization exception when the Test entity is detached and questions has not been initialized/fetched yet. You can either do a specific fetch, or depending on your configuration, you can call Test.getQuestions().size() before you exit the transaction.
References: How to solve lazy initialization exception using JPA and Hibernate as provider

Hibernate LazyInitializationException using Spring CrudRepository

SPRING JPA - org.hibernate.PersistentObjectException: detached entity passed to persist:

I've been stuck here for almost a week trying find the answer on the internet but sadly nothing worked. :( Everytime I try to update using this method:
private Tenant updateTenantWithApplicationProperties(List<TenantApplicationProperty> newTenantApplicationProperties, String tenantId) {
String reason = "Update application properties.";
Tenant existingTenant = tenantRepository.findById(tenantId);
List<TenantApplicationProperty> temp = existingTenant.getTenantApplicationProperties();
existingTenant.setTenantApplicationProperties(newTenantApplicationProperties);
setApplicationPropertiesUpdateValues(temp, existingTenant);
if(newTenantApplicationProperties != null && newTenantApplicationProperties.size() != 0) {
Tenant savedTenantWithAppProps = saveTenantWithLog(existingTenant, reason);
return savedTenantWithAppProps;
}
return existingTenant;
}
Im always getting this error:
javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist: com.infor.ecom.tenant.manager.model.entity.ApplicationProperty

In application property, you defined 1-1 relation like:
#OneToOne
#JoinColumn(name = "property_group_id")
private ApplicationPropertyGroup applicationPropertyGroup;
#OneToOne
#JoinColumn(name = "property_type_id")
private ApplicationPropertyType applicationPropertyType;
While you have not defined the same relation (note it should work bidirectionally i.e. say for e.g. if you as a person related to an employee id, then employee id is related to you as a person well) in individual property ApplicationPropertyGroup and ApplicationPropertyType.
You should add the same 1-1 relation in ApplicationPropertyGroup and ApplicationPropertyType with ApplicationProperty.
