Configuring ObjectMapper in Spring

Question

my goal is to configure the objectMapper in the way that it only serialises element which are annotated with @JsonProperty.

In order to do

Answer 1

I've used this with Jackson 2.x and Spring 3.1.2+

servlet-context.xml:

Note that the root element is , so you may need to remove beans and add mvc to some of these elements depending on your setup.

au.edu.unimelb.atcom.transfer.json.mappers.JSONMapper.java:

public class JSONMapper extends ObjectMapper {

    public JSONMapper() {
        SimpleModule module = new SimpleModule("JSONModule", new Version(2, 0, 0, null, null, null));
        module.addSerializer(Date.class, new DateSerializer());
        module.addDeserializer(Date.class, new DateDeserializer());
        // Add more here ...
        registerModule(module);
    }

}

DateSerializer.java:

public class DateSerializer extends StdSerializer {

    public DateSerializer() {
        super(Date.class);
    }

    @Override
    public void serialize(Date date, JsonGenerator json,
            SerializerProvider provider) throws IOException,
            JsonGenerationException {
        // The client side will handle presentation, we just want it accurate
        DateFormat df = StdDateFormat.getBlueprintISO8601Format();
        String out = df.format(date);
        json.writeString(out);
    }

}

DateDeserializer.java:

public class DateDeserializer extends StdDeserializer {

    public DateDeserializer() {
        super(Date.class);
    }

    @Override
    public Date deserialize(JsonParser json, DeserializationContext context)
            throws IOException, JsonProcessingException {
        try {
            DateFormat df = StdDateFormat.getBlueprintISO8601Format();
            return df.parse(json.getText());
        } catch (ParseException e) {
            return null;
        }
    }

}
