com.fasterxml.jackson.databind.JsonMappingException: Class CustomSerializer has no default (no arg) constructor #191

Closed snowdrop-bot closed 3 years ago

snowdrop-bot commented 3 years ago

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

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 {
        .
        .
        .
    }
}
