Add new module for deserialization in the @Filter annotation

[sondavide]

Hi, I'm using the last release 3.1.5:

com.turkraft.springfilter mongo 3.1.5

There is a way to register a new or custom module in the ObjectMapper deserializers?

If I have a class with a field of type Instant, this error comes out:

"Query: { "$expr" : { "$gte" : ["$instant", "[ERROR: (com.fasterxml.jackson.databind.exc.InvalidDefinitionException) Java 8 date/time type java.time.Instant not supported by default: add Module "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" to enable handling]"]}}, Fields: {}, Sort: {}"

There's a way to add jackson-datatypee-jsr310?

Hi @sondavide,

Spring Filter simply autowires the present ObjectMapper bean, without making any configuration to it. You may customize that behavior as it may be done in any Spring project, see this for example.

Hi @torshid , thanks for the help.
I'm trying to understand the problem, it's not a deserialization problem, because the JsonNodeHelperImpl has the correct ObjectMapper and the rightResult in the transform function is of type Instant.
If I use the classic mongo repository query:

    @Query("{$expr: {$eq: ['$DATA_INSTALLAZIONE', ?0 ]}}")
    List<Civic> getByDate(Instant data);

it works and finds the correct datas, if I use the @filter annotation, something does not work

finally I used a custom converter:

@Service
public class CustomInstantConverter implements Converter<String, CustomInstant> {

  @Override
  public CustomInstant convert(String source) {
    return new CustomInstant(source);
  }

  @Data
  @NoArgsConstructor
  public static class CustomInstant implements Serializable {

    @Data
    @NoArgsConstructor
    @AllArgsConstructor
    public static class DateFromString implements Serializable{
        public String dateString;
    }


    @JsonProperty("$dateFromString")
    public DateFromString dateFromString;

    public CustomInstant(String source) {
        this.dateFromString= new DateFromString(source);
    }


  }


}

$dateFromString saved me

Thanks for sharing the solution!
