Quarkus, PanacheEntity and saving lists or sets

Magick :

I'm trying to persist an entity that contains associated entities:

@Entity
public class Indicator extends PanacheEntity {
    @Id @GeneratedValue private Long id;
    public String name;
    @OneToMany(mappedBy="id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
    public List<IndicatorInput> inputs;
    @OneToMany(mappedBy="id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
    public Set<IndicatorOutput> outputs;    
}

The collections are:

@Entity
public class IndicatorInput extends AbstractIndicatorValue {

    @Id @GeneratedValue private Long id;

}

and

@Entity
public class IndicatorOutput extends AbstractIndicatorValue {
    @Id @GeneratedValue private Long id;
    public String color;
    public String style;

}

When I try to persist an Indicator instance, via REST, it fails with the below error:

Or the following, depending on what I have tried

com.fasterxml.jackson.databind.JsonMappingException: 'void io.priceinsight.indicators.entities.AbstractIndicatorValue.$$_hibernate_write_description(java.lang.String)'
 at [Source: (io.quarkus.vertx.http.runtime.VertxInputStream); line: 5, column: 22] (through reference chain: io.priceinsight.indicators.entities.Indicator["inputs"]->java.util.ArrayList[0]->io.priceinsight.indicators.entities.IndicatorInput["description"])

What I have tried

1. change quarkus-resteasy-jsonb to resteasy-jackson
2. Change for using List to Set
3. Have tried annotating the abstract class with @Inheritance
4. Have tried annotating the abstract class with @MappedSuperclass
5. public no-arg constructor to each entity
6. Add super(); to the constructor body
7. Add @RegisterForReflection to entities
8. Add implements Serializable to entities
9. Used cascade = CascadeType.PERSIST

Dmytro Chaban :

You have a combination of a few issues here.

1. PanacheEntity itself contains id field. So you need to either remove your id field from Indicator or make Indicator extend PanacheEntityBase.
2. Your id is private which only brings issues on deserialization(especially with PanacheEntity which already have id field). So make it either public or create getters and setters.
3. I also added strategy to @GeneratedValue as Identity to make it incrementable

Below is a working implementation for me. There's no example of AbstractIndicatorValue, so I'm assuming it's class that extends PanacheEntity.

• IndicatorInput.java

@Entity
// Make AbstractIndicatorValue extend PanacheEntityBase
public class IndicatorInput extends PanacheEntityBase {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public Long id;
}

• IndicatorOutput.java

@Entity
// Make AbstractIndicatorValue extend PanacheEntityBase
public class IndicatorOutput extends PanacheEntityBase {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public Long id;
    public String color;
    public String style;
}

• Indicator.java

@Entity
public class Indicator extends PanacheEntityBase {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public Long id;
    public String name;
    @OneToMany(mappedBy = "id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
    public List<IndicatorInput> inputs;
    @OneToMany(mappedBy = "id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
    public Set<IndicatorOutput> outputs;
}
