I'm looking for a way to directly convert some POJO to a Jackson TreeModel . I know that a translation from POJO-to-JSON-String exists, and TreeModel-to-JSON-String is supported — hovewer I am looking for a POJO-to-TreeModel translation. Is there a way? The use-case is as follows: Server-side templating is done with the Java implementation of Mustache. This uses Jackson's TreeModel. After that, I need a slimmed-down version of the TreeModel on the client-side, so I want to be able to first filter the TreeModel, serialize that to JSON, then send it to the client-side for further processing. This, ideally, involves two serialization steps. However, in my workaround, I am currently using three — which you can see here: map = // a map of pojos with jackson annotations //pojo >> JSON StringWriter w = new StringWriter(); objectmapper.writeValue(new JsonFactory().createJsonGenerator(w), map); String json = w.toString(); w.close(); //JSON >> Treemodel JsonNode tree = GenericJcrDTO.mapper.readTree(json); //filter tree here //treemodel >>JSON StringWriter w = new StringWriter(); GenericJcrDTO.mapper.writeValue(new JsonFactory().createJsonGenerator(w), tree); json = w.toString(); w.close(); Anyone?
