how to solve this error?
I ran the program but it showed this error.

Try adding this tag #EnableJpaRepositories in your MainApplication class and #ComponentScan(basePackages = {
"your entities package.*"
}

And this test is wrong, because the expected here is "[]" and I'm getting " [{"productId":1,"productName":"Maria","priceInEuros":232.0,"createdAt":null},{"productId":2,"productName":"Maria","priceInEuros":232.0,"createdAt":null}]" which is correct... the expected is null, why ?

Soft Deletion with Spring JPA

I've done a few changes on my code, because now I want to have a soft deletion instead of a normal one.
I would only need a few JPA annotations for this purpose.
I think I got the right idea, but now I can't even run it because it give the following error:
"""Type mismatch: cannot convert from String to Class<?>"""
My CloudProduct.java ( the one with the error ) :
package com.proj.my.model;
import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.EntityListeners;
import jakarta.persistence.Id;
import java.sql.Date;

public class CloudProduct {
#Id
private String productId;
private String productName;
private String productPrice;
#CreationTimestamp
#Column(updatable = false, name = "created_at")
private Date createdAt;
private boolean deleted = Boolean.FALSE;
public Boolean getDeleted() {
return deleted;
}
public void setDeleted(boolean deleted) {
this.deleted = deleted;
}
public CloudProduct(String productId, String productName, String productPrice, Date createdAt, boolean deleted) {
this.productId = productId;
this.productName = productName;
this.productPrice = productPrice;
this.createdAt = createdAt;
this.deleted = deleted;
}
public CloudProduct() {
}
public String getProductId() {
return productId;
}
public void setProductId(String productId) {
this.productId = productId;
}
public String getProductName() {
return productName;
}
public void setProductName(String productName) {
this.productName = productName;

this.productPrice = productPrice;
}
public Date getCreatedAt() {
return createdAt;
}
public void setCreatedAt(Date createdAt) {
this.createdAt = createdAt;
}
}
The error is implicit on :
#FilterDef(name = "deletedProductFilter", parameters = #ParamDef(name = "isDeleted", type = "boolean"))
Specifically on the "type = "boolean" ".

Cannot construct instance of `Instrutor`: no int/Int-argument constructor/factory method to deserialize from Number value

I'm trying to build an API with Spring Boot, but I keep getting an error when dealing with #OneToMany entities. The Bean seem to not be able to get an entity I'm referencing by ID through the JSON from the database and constructing it to insert into the other entity. Sounds complicated, so here's the code for everything and the error. I googled and googled and couldn't find a fitting answer to my specific situation.

Using UUID With Spring boot Data

im using UUID in my application as Primary Key i have problem whene find data by id give me exception error.
this is Note Class
package com.example.demo.model;
import java.util.Date;
import java.util.UUID;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import org.hibernate.annotations.GenericGenerator;
import org.springframework.boot.autoconfigure.AutoConfigurationPackage;
#AutoConfigurationPackage
#Entity
public class Note {
#Id
#GeneratedValue( strategy = GenerationType.AUTO,generator = "pg-uuid")
#GenericGenerator(name = "pg-uuid",strategy = "uuid2")
private UUID id;
private String title;
private String text;
#ManyToOne(fetch = FetchType.LAZY,cascade = CascadeType.MERGE)
private Notebook notebook;
private Date lastModifiedOn;
public UUID getId() {
return id;
}
public void setId(UUID id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public Notebook getNotebook() {
return notebook;
}
public void setNotebook(Notebook notebook) {
this.notebook = notebook;
}
public Date getLastModifiedOn() {
return lastModifiedOn;
}
public void setLastModifiedOn(Date lastModifiedOn) {
this.lastModifiedOn = lastModifiedOn;
}
this is NoteController

this is MyMapper to mape the json data

this is repositry class

import com.example.demo.model.Note;
import com.example.demo.model.Notebook;
#Repository
public interface NoteRepository extends JpaRepository<Note, UUID> {
List<Note> findAllByNotebook(Notebook notebook);
}
this is error is appears org.springframework.dao.EmptyResultDataAccessException: No class com.example.demo.model.Notebook entity with id 7e83b195-eb81-4752-a6fa-a5206c9eb1c6 exists!
