Answer 1

Here is what I have used:

@RequestMapping("/alluserreportJSON")
public @ResponseBody String getusersJSON() {
    ObjectMapper objectMapper = new ObjectMapper();
    //Set pretty printing of json
    objectMapper.enable(SerializationFeature.INDENT_OUTPUT);
    List userlist = null;
    @SuppressWarnings("unused")
    String exception = null;
    String arrayToJson = null;
    try {
        userlist = userService.findAllUsers();
        arrayToJson = objectMapper.writeValueAsString(userlist);
    } catch (Exception ex) {
        ex.printStackTrace();
        exception = ex.getMessage();
    }
    return arrayToJson;
}

Hope it helps someone. You can see it working here.
