I tried using ObjectMapper, but this does not seem correct.

You can do this without creating POJO and converting it into JSON. I assume your data in the Record object.

        JsonNode rootNode = mapper.createObjectNode();
        ArrayNode childNodes = mapper.createArrayNode();
        for (Record record : records) {
            JsonNode element = mapper.createObjectNode();
            ((ObjectNode) element).put("mime": record.getDirectory());
                  //fill rest of fields which are needed similar to this.
                  //Also here record.getDirectory() method will should return "directory"
                  //according to your json file.
            childNodes.add(element);
        }
        ((ObjectNode) rootNode).put("files", childNodes);
