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));     } } 

servlet.xml

NumbersOfNewEvents

public class NumbersOfNewEvents implements StatusAttribute {      public Integer newAccepts;     public Integer openRequests;      public NumbersOfNewEvents() {         super();     } } 

Answer 1

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;     } } 

Answer 2

It may be because I'm using Spring 3.1 (instead of Spring 3.0.5 as your question specified), but Steve Eastwood's answer didn't work for me. This solution works for Spring 3.1:

In your spring xml context:

<mvc:annotation-driven>     <mvc:message-converters>         <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>         <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>         <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">             <property name="objectMapper" ref="jacksonObjectMapper" />         </bean>             </mvc:message-converters> </mvc:annotation-driven>  <bean id="jacksonObjectMapper" class="de.Company.backend.web.CompanyObjectMapper" />
