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 so I followed this explanation which says how to configurate the objectmapper.

I included the custom objectmapper as described here.

However when the class NumbersOfNewEvents is serialized it still contains all attributes in the json.

Does anybody have a hint? Thanks in advance

Jackson 1.8.0 spring 3.0.5

CustomObjectMapper

public class CompanyObjectMapper extends ObjectMapper {
    public CompanyObjectMapper() {
        super();
        setVisibilityChecker(getSerializationConfig()
                .getDefaultVisibilityChecker()
                .withCreatorVisibility(JsonAutoDetect.Visibility.NONE)
                .withFieldVisibility(JsonAutoDetect.Visibility.NONE)
                .withGetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withIsGetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withSetterVisibility(JsonAutoDetect.Visibility.DEFAULT));
    }
}

NumbersOfNewEvents

public class NumbersOfNewEvents implements StatusAttribute {

    public Integer newAccepts;
    public Integer openRequests;

    public NumbersOfNewEvents() {
        super();
    }
}

Using Spring Boot (1.2.4) and Jackson (2.4.6) the following annotation based configuration worked for me.

@Configuration
public class JacksonConfiguration {

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);

        return mapper;
    }
}
