com.fasterxml.jackson.databind.JsonMappingException: Class CustomSerializer has no default (no arg) constructor #12345

banifou · 2020-09-25T14:13:58Z

Describe the bug
I'm using a custom serialiser extending com.fasterxml.jackson.databind.ser.std.StdSerializer to serve a REST Api. It works fine in OpenJDK 11. When I run it in native mode, I get a no default (no arg) constructor error.

Expected behavior
Get my java object serialized serving/producing an application/json endpoint.

Actual behavior
When i try to get the serialized entity object retrieved from Postgresql with the native image (in GET) it does throw error

com.fasterxml.jackson.databind.JsonMappingException: Class com.example.utils.BookSerializer has no default (no arg) constructor (through reference chain: java.util.ArrayList[1]->com.example.model.entities.OfferBasket["bookBaskets"]->org.hibernate.collection.internal.PersistentSet[0]->com.example.model.entities.BookBasket["bookList"]->org.hibernate.collection.internal.PersistentSet[0])

Note that the class actually does have a no-arg constructor:

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.SerializerProvider;
import com.fasterxml.jackson.databind.ser.std.StdSerializer;
import com.example.model.entities.Book;
import java.io.IOException;

public class BookSerializer extends StdSerializer<Book> {

    public BookSerializer(Class<Book> t) {
        super(t);
    }
    
    public BookSerializer() {
       super(Book.class);
   }

    @Override
    public void serialize(Book book, JsonGenerator jsonGenerator, SerializerProvider sp) throws IOException {
        .
        .

Hi,

How do you register your serializer with Jackson?

banifou · 2020-09-28T08:24:24Z

Hi, in the entity bean like this @JsonSerialize(using = BookSerializer.class)

gsmet · 2020-09-28T08:38:00Z

We have some code to deal with that but apparently we're missing something.

Could you prepare a small reproducer so that we can have a look?

Thanks!

What you added does not appear to be a Quarkus project

zipper01 · 2023-01-09T15:08:41Z

@geoand sorry it's not a Quarkus project (at the moment). I am trying to use GraalVM to generate the native image. When googling for the exception I came across this ticket it looks highly matches my case - same exception from the same library.

geoand · 2023-01-09T15:09:50Z

Quarkus does extra work to make things like that happen - if you don't use Quarkus, you need to configure GraalVM yourself.

zipper01 · 2023-01-09T15:35:52Z

Ok, thank you.
