春季：返回@ResponseBody“ ResponseEntity>”

现在我回来了

Object

@RequestMapping(value="", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)public @ResponseBody ResponseEntity<Object> getAll() {    List<Entity> entityList = entityManager.findAll();    List<JSONObject> entities = new ArrayList<JSONObject>();    for (Entity n : entityList) {        JSonObject Entity = new JSonObject();        entity.put("id", n.getId());        entity.put("address", n.getAddress());        entities.add(entity);    }    return new ResponseEntity<Object>(entities, HttpStatus.OK);}
