Use of ToStringSerializer via @JsonSerialize on int/long property does not work

[wujimin]

Description

• jdk 11 (not test with jdk 8)
• jackson 2.11.2 / 2.11.3
• primitive field with @JsonSerializer

        @JsonSerialize(using = ToStringSerializer.class)
        private int primitiveValue;

• if primitiveValue is 10
  • if not work with afterburner, will serialize to "10"
  • if work with afterburner, will serialize to 10

seems afterburner not handle primitive field @JsonSerialize annotation

Reproduce case

public class AfterBurnerPrimitiveSerializerBug {
    public static class Model {
        @JsonSerialize(using = ToStringSerializer.class)
        private int primitiveValue;

        @JsonSerialize(using = ToStringSerializer.class)
        private Integer value;

        public int getPrimitiveValue() {
            return primitiveValue;
        }

        public Model setPrimitiveValue(int primitiveValue) {
            this.primitiveValue = primitiveValue;
            return this;
        }

        public Integer getValue() {
            return value;
        }

        public Model setValue(Integer value) {
            this.value = value;
            return this;
        }
    }

    public static class AnotherModel extends Model {

    }

    static Model model = new Model().setPrimitiveValue(10).setValue(10);

    static Model anotherModel = new AnotherModel().setPrimitiveValue(10).setValue(10);

    static ObjectMapper mapper = new ObjectMapper();

    public static void main(String[] args) throws JsonProcessingException {
        // will print: {"primitiveValue":"10","value":"10"}
        System.out.println(mapper.writeValueAsString(model));

        mapper.registerModule(new AfterburnerModule());
        // will print: {"primitiveValue":10,"value":"10"}
        // primitiveValue lost JsonSerialize feature
        System.out.println(mapper.writeValueAsString(anotherModel));
    }
}

output

{"primitiveValue":"10","value":"10"}

Thank you for reporting this, I hope to look into this soon.

I can reproduce this as shown.

Specific reported problem was fixed; also found another related issue (#118) to try to fix.
Patch will be included in 2.12.0 release which should be out in about a week.

thanks, we will optimize our code
