@JsonDeserialize not working on field

@JsonDeserialize not working on field.

Using Spring Boot 2 and Jackson 2.11.3.

Code:

@Data
public class EventOddPOJO {

    @JsonProperty("id")
    private String id;

    @JsonDeserialize(using = EventOddPartDeserializer.class)
    private String part;

    @JsonProperty("ss")
    private String score;

    @JsonDeserialize(using = EventOddMinuteDeserializer.class)
    private String minute;

    @JsonDeserialize(using = EventOddSecondDeserializer.class)
    private String second;

    @JsonProperty("over_od")
    private String overOd;

    @JsonProperty("home_od")
    private String homeOd;

    @JsonProperty("draw_od")
    private String drawOd;

    @JsonProperty("away_od")
    private String awayOd;

    @JsonProperty("under_od")
    private String underOd;

    @JsonProperty("time_str")
    private String timeStr;

    @JsonProperty("add_time")
    private String addTime;

    @JsonProperty("handicap")
    private String handicap;

    public static class EventOddPartDeserializer extends StdDeserializer < String > {

        public EventOddPartDeserializer() {
            this(null);
        }

        public EventOddPartDeserializer(Class < ? > vc) {
            super(vc);
        }

        @Override
        public String deserialize(JsonParser p, DeserializationContext ctxt) throws IOException,
        JsonProcessingException {

            String timeStr = p.getValueAsString("timeStr");

            if (Objects.isNull(timeStr)) {
                return "-";
            }

            return timeStr.split(" - ")[0];

        }
    }

    public static class EventOddMinuteDeserializer extends StdDeserializer < String > {

        public EventOddMinuteDeserializer() {
            this(null);
        }

        public EventOddMinuteDeserializer(Class < ? > vc) {
            super(vc);
        }

        @Override
        public String deserialize(JsonParser p, DeserializationContext ctxt) throws IOException,
        JsonProcessingException {

            String timeStr = p.getValueAsString("timeStr");

            if (Objects.isNull(timeStr)) {
                return "-";
            }

            return timeStr.split(" - ")[1].split(":")[0];

        }
    }

    public static class EventOddSecondDeserializer extends StdDeserializer < String > {

        public EventOddSecondDeserializer() {
            this(null);
        }

        public EventOddSecondDeserializer(Class < ? > vc) {
            super(vc);
        }

        @Override
        public String deserialize(JsonParser p, DeserializationContext ctxt) throws IOException,
        JsonProcessingException {

            String timeStr = p.getValueAsString("timeStr");

            if (Objects.isNull(timeStr)) {
                return "-";
            }

            return timeStr.split(" - ")[1].split(":")[1];

        }
    }

}

Json:

{
                    "id": "35008186",
                    "home_od": "1.952",
                    "handicap": "+3.5",
                    "away_od": "1.740",
                    "ss": "95:98",
                    "time_str": "4 - 04:08",
                    "add_time": "1603807890"
}

I had the same issue using spring boot version 2.5.6. I resolved it by adding a no arguments constructor to the POJO class.

The primary method for deserializing objects of the BeanDeserializer.java class the is using a flag called _vanillaProcessing. In my case without a no arguments constructor, _vanillaProcessing was disabled and another deserializer was used. However with a no arg constructor _vanillaProcessing was enabled and my custom JsonDeserialize was triggered.

I´m using a spring boot version 2.3.9.RELEASE and i´m have the same problem.
