Why it's?
I was looking for a solution and I haven't found anything, any help?
I thought the problem was the LONG but that's okay

I think the answer is within the error
nested exception is java.lang.IllegalArgumentException: Not a managed type: class java.lang.Character
You are trying to use java.lang.Character instead of your model "Character".
Try importing it with yourpackage.Character or I would prefer renaming the Character
to something else.

AnnotationException: Unable to map collection

I am writing an online store using Spring Boot and hiberbate. I have an Order class where I need a Сart link with relationhip #OneToMany. I created all tables and created all the fields I needed. Added links to Java-code but still throws an error. I can't understand what's the matter.
I can't figure out where I made a mistake in the mapping. Could this error be related to something else?
Class Cart:
#Data
#Entity
#IdClass(Cart.CartId.class)
#Table(name = "cart_products")
public class Cart {
#NoArgsConstructor
#AllArgsConstructor
static class CartId implements Serializable {
private Long orderIds;
private Long drinkIds;
}
// Fields
//
#Id
private Long orderIds;
#Id
private Long drinkIds;
#ManyToOne
#JoinColumn(name = "order_id", referencedColumnName = "id")
private Order order;
#ManyToOne
#JoinColumn(name = "drink_id", referencedColumnName = "id")
private Drink drink;
private int count;
}
Class Order:
#Entity
#Table(name = "pg_order")
public class Order {
// Fields
//
private #Id
#GeneratedValue
Long id;
private String address;
#Column(name = "phone_number")
private String phoneNumber;
#Temporal(TemporalType.TIMESTAMP)
#Column(name = "date_order")
private Date dateOrder;
#Enumerated(EnumType.STRING)
#Column(name = "order_status")
private OrderStatus orderStatus;
#Column(name = "total_cost")
private BigDecimal totalCost;
// Relationships
//
#ManyToOne
#JoinColumn(name = "user_id")
private User user;
#OneToMany
#JoinColumns({
#JoinColumn(name = "order_id", referencedColumnName = "order_id"),
#JoinColumn(name = "drink_id", referencedColumnName = "drink_id")
})
private Set<Cart> cart;
}

Your mapping is wrong here:
#OneToMany
#JoinColumns({
#JoinColumn(name = "order_id", referencedColumnName = "order_id"),
#JoinColumn(name = "drink_id", referencedColumnName = "drink_id")
})
private Set<Cart> cart;
You're saying that there is both on Order and Cart table a order_id and drink_id column, which is not the case.
Actually since you have the mapping defined on the child side (where #ManyToOne resides), you can simply refer to that mapping on the parent side:
#OneToMany(mappedBy = "order")
private Set<Cart> cart;

Jpa repository special words like "and' , "or" not working

I have a simple UserRepository which extends JpaRepository.
I am trying to find a user for a given username and password.
Here is my repository class
public interface UserRepository extends JpaRepository<User, Integer> {
public Optional<User> findByusUnameAndusPassword(String username, String password);
}
Here is my entity class
public class User implements java.io.Serializable {
#Id
#Column(name = "us_id", unique = true, nullable = false)
private int usId;
#Column(name = "us_uname", unique = true, nullable = false)
private String usUname;
#Column(name = "us_password", nullable = false, length = 100)
private String usPassword;
}
This is the error that I am getting
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract java.util.Optional com.example.repository.UserRepository.findByusUnameAndusPaasword(java.lang.String,boolean)!

How to perform a JOIN query with spring jpa?

I'm trying to setup a join query between these two tables using Spring jpa :
https://image.noelshack.com/fichiers/2019/06/5/1549636975-relation.png
I've tried doing this in my student repository :
#Query("SELECT id FROM Student JOIN Offer ON Offer.id=Student.school.id")
but it keeps giving me an error when i try to execute my code
Here is my Student Entity :
package EIC.com.example.Backend.Entity;
import org.hibernate.annotations.Cascade;
import javax.persistence.*;
#Entity
#Table(name = "etudiant")
public class Student {
#Id
#Column(name="Apogee")
private int id;
#Column(name="Prenom")
private String first_name;
#Column(name="Nom")
private String last_name;
#Column(name="Classement")
private int rank;
#Column(name="Filiere")
private String speciality;
#ManyToOne
#JoinColumn(name = "Offre")
private Offer school;
/* Getters Setters Constructors */
}
And my Offer Entity :
package EIC.com.example.Backend.Entity;
import javax.persistence.*;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
#Entity
#Table(name = "offre")
public class Offer {
#Id
#Column(name = "ID_OFFRE")
private int id;
#Column(name = "Type")
private int type; // 0 for DD 1 for MOBILITY
#Column(name = "Etablissement")
private String school;
#Column(name = "Filiere_Concerne")
private String target;
#Column(name = "Nb_place")
private int seats;
#Column(name = "Delai")
private Date limit;
#OneToMany
#JoinColumn(name = "Offre")
private List<Student> students=new ArrayList<>();
/* GETTERS SETTERS CONSTRUCTORS */
}

Try it with the following. This way the university gets loaded eagerly. This is only good in situations that you only load 1 university. If you do it for example with the university you will load a list of all the students and their attributes. Now when you load a student by id it will also fetch the university
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "Offre")
private Offer school;

Add field offerId in your Student entity
#Column(name = "OfferId")
private int offerId;
And change to
#ManyToOne
#JoinColumn(name = "OfferId")
private Offer school;
In your Offer entity, change to
#OneToMany(fetch = FetchType.LAZY, mappedBy = "school")
private List<Student> students = new ArrayList<>();
Then try this #Query
#Query("SELECT id FROM Student std JOIN Offer off ON off.id = std.offerId")
