Lombok 1.18.0 and Jackson 2.9.6 not working together

Question

The deserialization is failing after the update.

I updated my micro-service from Spring 1.5.10.RELEASE to Spring 2.0.3.RELEASE

Answer 1

You want to deserialize a class which has final field. so u need to declare a constructor which contains final field to deserialize.

@Data
@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonIgnoreProperties(ignoreUnknown = true)
public class ErrorDetail {

private final String heading;
private final String detail;
private String type;

@JsonCreator
public ErrorDetail(@JsonProperty("heading") String heading, @JsonProperty("detail") String detail) {
    this.heading = heading;
    this.detail = detail;
}
}

and when deserialize with mapper need to MapperFeature.ALLOW_FINAL_FIELDS_AS_MUTATORS set this property false.

private static  T asObject(final String str, Class clazz) {
    try {
        return new ObjectMapper().configure(MapperFeature.ALLOW_FINAL_FIELDS_AS_MUTATORS,false).readValue(str, clazz);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}
