I have a problem with the find() method.
I have a 'DueDiligenceGestori' class that maps a database table. The primary key of the table is a number(19) and therefore I mapped the entity with a Long as previously done
Here is the class
package com.xxx.model.duediligencegestori;
import java.io.Serializable;
import java.util.Date;
import javax.persistence.CascadeType;
import javax.persistence.Column;

import com.xxx.model.AbstractVersionEntity;

import com.xxx.model.duediligence.DueDiligenceEnumType;
import com.xxx.model.masterData.Person;
/**

@Entity
@Table(name = "DUEDILIGENCE_GESTORI")
public class DueDiligenceGestori extends AbstractVersionEntity implements Serializable {

public DueDiligenceGestori() {
}
@Id

@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "DUEDILIGENCE_GEST_ID_SEQ_GENERATOR")
@Column(name = "ID", unique = true, nullable = false)
private Long id;
@JoinColumn(name = "DUEDILIGENCE_ID", unique = true)
@OneToOne(cascade = CascadeType.ALL)
private DueDiligence dueDiligence;
@Column(name = "IDENTIFICATIVO_SCHEDA", unique = true, nullable = false, length = 4000)
private String identificativoScheda;
@Column(length = 25)

@JoinColumn(name = "CAPO_AREA")
private Person capoArea;
@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FUEL_S3")
private Person fuelS3;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public DueDiligence getDueDiligence() {
return dueDiligence;
}

this.dueDiligence = dueDiligence;
}

I tried to cast, debug but everything seems to have passed correctly. Does anyone know how to act? Thank you all

It seem that when you're calling the EntityManager.find interface, you're invoking it with the wrong type.
Somewhere (I'm guessing by the stack in repository.impl.DueDiligenceGestoriRepositoryImpl.getDueDiligenceGestori) you have something like this:
em.find(DueDiligenceGestori.class, 12);
// or
int id; // parameter
em.find(DueDiligenceGestori.class, id);
You need to convert that to long first. If it's a constant, then 12L, if it's a primitive, then (long) id, if it's an Integer object, you need a null check, then call id.longValue().
