Title Body

I have a spring webservice that returns a json response. I'm using the example given here to create the service: http://www.mkyong.com/spring-mvc/spring-3-mvc-and-json-example/ The format the json is returned in is: {"name":null,"staffName":["kfc-kampar","smith"]} I want to remove any null objects from the returned response so it looks like this: {"staffName":["kfc-kampar","smith"]} I've found similar questions asked here but I've been able to get a solution working e.g. Configuring ObjectMapper in Spring How to configure MappingJacksonHttpMessageConverter while using spring annotation-based configuration? configuring the jacksonObjectMapper not working in spring mvc 3 how to configure spring mvc 3 to not return "null" object in json response? Spring configure @ResponseBody JSON format Jackson+Spring3.0.5 custom object mapper From reading through these and other sources, I figured the cleanest way to achieve what I wanted was to use Spring 3.1 and the message-converters that can be configured within the mvc-annotation. My updated spring config file is: <beans xmlns="http://www.springframe
