I've achieved this for Jackson as follows. I've no idea if this is a good solution, but it works!: 1) Create a Spring Factory Bean for creating JacksonDataFormat instances. i.e. <bean id="json-jackson" class="my.JacksonDataFormatFactory"/> 2) In my factory's getObject() method so something like: ObjectMapper mapper = new ObjectMapper(); //There are a bunch of properties than don't have matching getters & setters. Ignore these on deserialisation. mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); //We need to include type info for properties of abstract types, so we can deserialise them. mapper.enableDefaultTyping(); mapper.registerModule(new JacksonCustomisationModule()); JacksonDataFormat df = new JacksonDataFormat(mapper, null); return df;
I use a custom Jackson SimpleModule where I register a number of mixins. This allows me add some annotations to classes which are part of a different project.
