Not correct list #OneToMany and #ManyToOne Jpa - spring-boot

Question

I am trying to list from child(Person/Person) to parent(Company/Company).
Previously it had infinite loop problems, but
#JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
fixed it.
Here is the code:
Empresa.class
package com.demo.clase7.Entity;
import com.fasterxml.jackson.annotation.*;
import com.sun.istack.NotNull;
import lombok.*;
import javax.persistence.*;
import java.io.Serializable;
import java.util.Date;
import java.util.List;
import java.util.Set;
#Data
#NoArgsConstructor
#AllArgsConstructor
#Entity(name = "empresa")
#JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class Empresa {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "razon_social")
private String razonSocial;
private String ruc, representante;
#Column(name = "fecha_creacion")
private Date fechaCreacion;
#OneToMany(mappedBy = "empresa", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private List<Persona> personaList;
}
Persona.class
package com.demo.clase7.Entity;
import com.demo.clase7.Entity.Empresa;
import com.fasterxml.jackson.annotation.*;
import lombok.*;
import javax.persistence.*;
import java.io.Serializable;
#Data
#NoArgsConstructor
#AllArgsConstructor
#Entity(name = "persona")
#JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class Persona {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String nombre, email, direccion, telefono;
#ManyToOne()
#JoinColumn(name = "empresa_id")
private Empresa empresa;
}
so when list Empresa (Company's), it gives me this result, which is correct
[
{
"id": 1,
"razonSocial": "oswaldo",
"ruc": "23aaasd2424",
"representante": "silviopd222",
"fechaCreacion": "1995-01-01T00:00:00.000+00:00",
"personaList": [
{
"id": 4,
"nombre": "oswal peña diaz",
"email": "pedi#gmail.com",
"direccion": "las viñas 149",
"telefono": "234982734",
"empresa": 1
},
{
"id": 5,
"nombre": "oswal peña diaz",
"email": "pedi#gmail.com",
"direccion": "las viñas 149",
"telefono": "234982734",
"empresa": 1
}
]
},
{
"id": 2,
"razonSocial": "oswaldo",
"ruc": "23aaasd2424",
"representante": null,
"fechaCreacion": null,
"personaList": []
},
{
"id": 4,
"razonSocial": "silviopd",
"ruc": "232424",
"representante": "silviopd2",
"fechaCreacion": "1992-01-01T00:00:00.000+00:00",
"personaList": []
}
]
so when I list Persona (people), it gives me this result which is wrong.
If you realize in the array it is made up of numbers
[
{
"id": 1,
"nombre": "oswal peña diaz",
"email": "pedi#gmail.com",
"direccion": "las viñas 149",
"telefono": "234982734",
"empresa": null
},
{
"id": 4,
"nombre": "oswal peña diaz",
"email": "pedi#gmail.com",
"direccion": "las viñas 149",
"telefono": "234982734",
"empresa": {
"id": 1,
"razonSocial": "oswaldo",
"ruc": "23aaasd2424",
"representante": "silviopd222",
"fechaCreacion": "1995-01-01T00:00:00.000+00:00",
"personaList": [
4,
{
"id": 5,
"nombre": "oswal peña diaz",
"email": "pedi#gmail.com",
"direccion": "las viñas 149",
"telefono": "234982734",
"empresa": 1
}
]
}
},

Answer 1

I found the solution, apparently the code
#JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
allowed me not to generate infinite loops, but when making the list from person it was not listed very well.
There is an infinite loop when listing by company which is generated by the "company" object found in the Persona.class and at the same time there is an infinite loop when listing person that is generated by the list "personList" that is in Empresa.class.
To solve both loops do the following:
For the Empresa class we add
#JsonIgnoreProperties("empresa")
For the Persona class we add
#JsonIgnoreProperties("personaList")
I leave here the final code

#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String nombre, email, direccion, telefono;
#ManyToOne(cascade = CascadeType.ALL)

#JsonIgnoreProperties("personaList")
private Empresa empresa;
}
