When I tried to use Lombok to generate default and parameterized constructor using spring-boot it gives error?

Question

How to use the default and parameterized constructor using Lombok, after using the Lombok annotations for Constructor?

I have added the Lombok dependency in pom.xml but when I create the default and parameterized constructor it gives the error, The constructor BadgeCard(null, null, int, null) is undefined

BadgeCard.java

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import lombok.AllArgsConstructor;
import lombok.EqualsAndHashCode;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.RequiredArgsConstructor;
import lombok.ToString;

@NoArgsConstructor
@RequiredArgsConstructor
@AllArgsConstructor
@Getter
@ToString
@EqualsAndHashCode
@Entity
public class BadgeCard {

    @Id
    @GeneratedValue
    @Column(name = "BADGE_ID")
    private Long badgeId;
    private Long userId;
    private long badgeTimestamp;
    private Badge badge;    

public BadgeCard() {
        this(null, null, 0, null);
    }

    public BadgeCard(final Long userId, final Badge badge) {
        this(null, userId, System.currentTimeMillis(), badge);
    }

}

No, it's not duplicate. Actually I want to ask when I use Constructor annotation of Lombok. and write the default and parameterized constructor, I am getting the below errors. **The constructor BadgeCard(null, null, int, null) is undefined** — farhanlq, Sep 05 '19 at 07:10
You're having Lombok create a no-args constructor, yet you're writing one yourself, why? — Strelok, Sep 05 '19 at 07:30
That's what I want to ask I used the annotation, does it requires to create the create the constructer too? — farhanlq, Sep 05 '19 at 07:36
The code you present here has errors, but not the errors that you claim. Either that, or your annotation processing is not enabled at all. — Michael Piefel, Sep 10 '19 at 10:24

NoArgsConstructor and AllArgsConstructor annotations are just enough for that

ok, Is there any way to achieve constructor chaining using Lombok, Do you have any idea about that? – farhanlq Sep 05 '19 at 07:06
@farhanlq If you want constructor chaining, then you have to either write them yourself. – Mark Rotteveel Sep 05 '19 at 10:30
