I have a problem with the customization of my RESTEasy JSON response.
In web.xml
I use autoscan:
<context-param>
<param-name>resteasy.scan</param-name>
<param-value>true</param-value>
</context-param>
Here is my customization class for ObjectMapper
,
(I've set not null fields and new human readable date):
@Provider
@Produces(MediaType.APPLICATION_JSON)
public class JacksonConfig implements ContextResolver<ObjectMapper> {
private Logger log = Logger.getLogger(PropertiesConfig.LOG_CATEGORY);
private ObjectMapper objectMapper;
public JacksonConfig() throws Exception {
objectMapper = new ObjectMapper();
objectMapper.getSerializationConfig().setSerializationInclusion(JsonSerialize.Inclusion.NON_NULL);
objectMapper.setDateFormat(new SimpleDateFormat("dd.MM.yyyy"));
objectMapper.configure(SerializationConfig.Feature.WRITE_DATES_AS_TIMESTAMPS, false);
}
@Override
public ObjectMapper getContext(Class<?> arg0) {
return objectMapper;
}
}
Here is my servlet:
@Path("/search")
public class Search extends ArtesAPI {
@GET
@Path("/")
@Produces(MediaType.APPLICATION_JSON)
public Response search(@Context HttpServletRequest request){
RequestManager reqManager = new RequestManager(request);
MyResponse response = reqManager.doSearchRequest();
return Response.status(200).entity(response).build();
}
}
When I deploy to the server, RESTEasy prints this log:
10:43:44,320 INFO [TomcatDeployment] deploy, ctxPath=/MyServer
10:43:44,544 INFO [ConfigurationBootstrap] Adding scanned @Provider: myserver.servlets.JacksonConfig
10:43:44,545 INFO [ConfigurationBootstrap] Adding scanned resource: myserver.servlets.Search
But when I call the search API, I receive this response: (here a little part of response)
{
"entry": [
{
"name": "abbigliamento",
"description": null,
"lastUpdate": 1375448941000,
"subCategory": null
},
{
"name": "car",
"description": null,
"lastUpdate": null,
"subCategory": null
}
}
My server response gives me null fields and lastUpdate
in milliseconds.
Where have I gone wrong?
Thanks in advance.
You can customize Jackson serialization in Resteasy by extending JacksonJsonProvider
.
@Provider
public class MyJacksonJsonProvider extends JacksonJsonProvider
{
@Override
public void writeTo(Object value, Class<?> type, Type genericType, Annotation[] annotations,
MediaType mediaType, MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
throws IOException
{
ObjectMapper mapper = locateMapper(type, mediaType);
mapper.getSerializationConfig().setSerializationInclusion(JsonSerialize.Inclusion.NON_NULL);
mapper.setDateFormat(new SimpleDateFormat("dd.MM.yyyy"));
mapper.configure(SerializationConfig.Feature.WRITE_DATES_AS_TIMESTAMPS, false);
super.writeTo(value, type, genericType, annotations, mediaType, httpHeaders, entityStream);
}
}
