Deserialize Exception in spring hibernate with OneToOne Mapping

Deserialize Exception in spring hibernate with OneToOne Mapping - java

I am using Spring boot 2.1.2 with hibernate , and i have simple two model classes like user and user account, and these 2 models are connected with oneToOne mapping. When we call user, i need to get user account also. I just mapped user account model to user model with oneToOne mapping. But when i call user am facing one Deserialize Exception.

The problem seems to be in UserAccount class, where you defined usereName field as UserAccount type.
I think it should be a String.

Getting an error about not having an Identifier even when I have one

This is my UserRole class. Here, the id_roles, id_users and updated_by are supposed to be foreign keys (id_roles coming from the Role table and the other two coming from the User table, I'll put the code for each one of the tables down below)
package offgrid.models;
import io.quarkus.hibernate.reactive.panache.PanacheEntityBase;
import javax.persistence.*;
import java.time.LocalDateTime;
#Entity
#Access(AccessType.PROPERTY)
#Table(name = "user_roles")
public class UserRole extends PanacheEntityBase {
#EmbeddedId
private UserRolePK UserRolePK;
#OneToOne
#JoinColumn(name = "id_roles", referencedColumnName = "id")
private Role roleId;
#OneToOne
#JoinColumn(name = "id_users", referencedColumnName = "id")
private User userId;
#Column(name = "created_at")
private LocalDateTime createdAt;
#Column(name = "updated_at")
private LocalDateTime updatedAt;
#ManyToOne
#JoinColumn(name = "update_by", referencedColumnName = "name")
private User updatedBy;
public offgrid.models.UserRolePK getUserRolePK() {
return UserRolePK;
}
public void setUserRolePK(offgrid.models.UserRolePK userRolePK) {
UserRolePK = userRolePK;
}
public Role getRoleId() {
return roleId;
}
public void setRoleId(Role roleId) {
this.roleId = roleId;
}
public User getUserId() {
return userId;
}
public void setUserId(User userId) {
this.userId = userId;
}
public LocalDateTime getCreatedAt() {
return createdAt;
}
public void setCreatedAt(LocalDateTime createdAt) {
this.createdAt = createdAt;
}
public LocalDateTime getUpdatedAt() {
return updatedAt;
}
public void setUpdatedAt(LocalDateTime updatedAt) {
this.updatedAt = updatedAt;
}
public User getUpdatedBy() {
return updatedBy;
}
public void setUpdatedBy(User updatedBy) {
this.updatedBy = updatedBy;
}
}
And this is my UserRolePK
package offgrid.models;
import javax.persistence.Column;
import javax.persistence.Embeddable;
import java.io.Serializable;
import java.util.Objects;
#Embeddable
public class UserRolePK implements Serializable {
#Column(name = "user_id")
private Long userId;
#Column(name = "role_id")
private Long roleId;
public Long getUserId() {
return userId;
}
public void setUserId(Long userId) {
this.userId = userId;
}
public Long getRoleId() {
return roleId;
}
public void setRoleId(Long roleId) {
this.roleId = roleId;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
UserRolePK that = (UserRolePK) o;
return userId.equals(that.userId) && roleId.equals(that.roleId);
}
#Override
public int hashCode() {
return Objects.hash(userId, roleId);
}
}
Here is my User class

}
public String getTaxId() {
return taxId;
}
public void setTaxId(String taxId) {

}
public String getStatus() {

And the Role class

#Column(name = "created_at")
private LocalDateTime createdAt;
#Column(name = "updated_at")

private User updatedBy;
public UUID getId() {
return id;
}
public void setId(UUID id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public LocalDateTime getCreatedAt() {
return createdAt;
}
public void setCreatedAt(LocalDateTime createdAt) {
this.createdAt = createdAt;
}
public LocalDateTime getUpdatedAt() {
return updatedAt;
}
public void setUpdatedAt(LocalDateTime updatedAt) {
this.updatedAt = updatedAt;
}
public User getUpdatedBy() {
return updatedBy;
}
public void setUpdatedBy(User updatedBy) {
this.updatedBy = updatedBy;
}
}
I'm getting this error when I try to run my code:
Caused by: org.hibernate.AnnotationException: No identifier specified for entity: offgrid.models.UserRole
But as I detailed above, there I put an EmbeddedId annotation referencing my UserRolePK class.. Am I missing something?

It's because of:
#Access(AccessType.PROPERTY)
But you used annotations on fields.
Change it to:
#Access(AccessType.FIELD)
or remove it, as JPA know it is FIELD base on where you placed the annotations.

I always get ORA-00904 and ORA-00942 errors when creating History table even if the generator id used is the same as others. Any help much appreciated!!

Even while using Hibernate JPA you must not forget you use the Oracle database and you must avoid using reserved words as columns names.
So please review all columns names, particularly this one
#Column(name = "date")
The error ORA-00904 invalid identifier point in this direction. DATE is a reserved word and can't be used as column name.
The second one (ORA-00942 table or view does not exist) is a followup message caused by the fact that the table can't be created.

Invalid property 'stateId' of bean class Could not find field for property during fallback access

I'm getting the following error while trying to update a data in DB using SpringBoot
The error is: org.springframework.beans.NotReadablePropertyException: Invalid property 'stateId' of bean class [com.studawn.model.District]: Could not find field for property during fallback access!
I don't know how to fix it.

booking.getSlot() and booking.getSubscriber() returns null
Please let me know if i miss some configuration while mapping
EDIT1
Added code how the entity is getting loaded
public Booking addBooking(String title,String desc,int slotid,int subscriberid,Session session){
Booking booking = new Booking();
booking.setTitle(title);
booking.setDesc(desc);
booking.setSlotid(slotid);
booking.setSubscriberid(subscriberid);
booking.setCreated(new Date());
Integer bookingid = (Integer) session.save(booking);
session.flush();
Booking bookingEntity = (Booking) session.createQuery("From Booking where id = ?").
setParameter(0, bookingid).list().get(0);
return bookingEntity;
}
I am saving the entity and reloading it.

It's not working because Hibernate is retuning the same instance it has already in its 1st level cache, which doesn't have a reference to any of the 2 other entities.
To fix this, you have to do a session.refresh(booking) rather than executing a query.

In your code :
booking.setSlotid(slotid);
booking.setSubscriberid(subscriberid);
You're just setting Integer values and not objects. Instead of this, try to set objects :
booking.setSlot(new Slot(slotid));
booking.setSubscriber(new Subscriber(subscriberid));
But as #Augusto said, the associations you're having in the session (Slot and Subscriber) are not full objects they contain only their ids. That's why you can't get other fields of these objects.

Now I am using Primefaces datatable to show a List<Activity> in which I have filtering on the field name of ActivityType. ActivityType is associated with Activity by #ManyToOne relationship.
For filtering the List<Activity> I am using:
Criteria criteria = getSessionFactory().getCurrentSession().createCriteria(Activity.class);
criteria.createCriteria("activityType").add(Restrictions.like("name", value.toString(), MatchMode.START));
I am getting:
null: org.hibernate.QueryException: duplicate association path: activityType
at org.hibernate.loader.criteria.CriteriaQueryTranslator.createAssociationPathCriteriaMap(CriteriaQueryTranslator.java:172) [hibernate-core-4.1.8.Final.jar:4.1.8.Final]

at com.edfx.adb.dao.ActivityDao.loadActivities(ActivityDao.java:54) [classes:]
at com.edfx.adb.service.ActivityService.loadActivities(ActivityService.java:101) [classes:]
This error is not showing always and never after the first load. After filtering the table for 5-6 time, I am having this error.
I am worried that if the mapping and the criteria is right or not. Any suggestion would be very helpful.

I think you need to provide an alias, so you should change your code this way:
Criteria criteria = getSessionFactory().getCurrentSession().createCriteria(Activity.class);
criteria.createCriteria("activityType", "at")
.add(
Restrictions.like("at.name", value.toString(), MatchMode.START));

The problem seems to be in UserAccount class, where you defined usereName field as UserAccount type. I think it should be a String.
