How to create an immutable Java Object from a Mongo datasource

I'm looking to create immutable Java objects directly from a Mongo collection, for example:

public final class Sample {

    private final String description;
    private final Integer min;
    private final Integer max;

    public Sample(String description, Integer min, Integer max) {
        this.description = description;
        this.min = min;
        this.max = max;
    }

    public String getDescription() {
        return description;
    }

    public Integer getMin() {
        return min;
    }

    public Integer getMax() {
        return max;
    }
}

I've been using the PojoCodecProvider to persist the objects, which works well. However I obviously can't use this for loading the object back, since there is no no-arg constructor:

//Doesn't work
MongoCollection<Sample> samples = db.getCollection("samples", Sample.class);

Is there a way to do this without extracting all the attributes from the Document and calling the constructor myself? There are going to be lots of these types of object and some will be quite large, if there's a convenient way to do this it would be a great help!

Many thanks.

You can add BSON annotations to your class as stated in mongoDB documentation:

https://mongodb.github.io/mongo-java-driver/3.5/bson/pojos/#supporting-pojos-without-no-args-constructors

<!-- language: java -->

@BsonDiscriminator
public final class Sample {

    private final String description;
    private final Integer min;
    private final Integer max;

    @BsonCreator
    public Sample(@BsonProperty("description") String description, @BsonProperty("min") Integer min, @BsonProperty("max") Integer max) {
        this.description = description;
        this.min = min;
        this.max = max;
    }

    public String getDescription() {
        return description;
    }

    public Integer getMin() {
        return min;
    }

    public Integer getMax() {
        return max;
    }
}
