Question

我想创建一个spring mvc rest调用，响应应该是mongo db（Basic）DBObject的结果。据我所知，DBObject是一个JSON对象。是可以返回这些对象还是应该返回它们的正常字符串内容？

这是我到目前为止的解决方案：

@RequestMapping(value = "/content/json/{ids}", method = RequestMethod.GET)
public ResponseEntity<String> getContentByIdsAsJSON(@PathVariable("ids") String ids)
{
  String content = null;
  StringBuilder builder = new StringBuilder();
  HttpHeaders responseHeaders = new HttpHeaders();
  responseHeaders.add("Content-Type", "text/html; charset=utf-8");

  List<String> list = this.contentService.findContentByListingIdAsJSON(ids);
  if (list.isEmpty())
  {
     content = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><error>no data found</error>";
     return new ResponseEntity<String>(content, responseHeaders, HttpStatus.CREATED);
  }
  for (String json : list)
  {
     builder.append(json + "\n");
  }
  content = builder.toString();
  return new ResponseEntity<String>(content, responseHeaders, HttpStatus.CREATED);
}

有没有人有更好的解决方案来满足这一要求？

我在你的代码中看到一个奇怪的东西。你必须返回json或xml吗？如果你必须返回json，那么在你的情况下这很简单，@ ResponseBody可以做到神奇

@RequestMapping(value = "/content/json/{ids}", method = RequestMethod.GET)
@ResponseBody
public MyGreatContentObject getContentByIdsAsJSON(@PathVariable("ids") String ids) {
   return this.contentService.findContentByListingId(ids);
}

无论如何，我认为你还必须多学习基础概念

spring mvc rest mongo dbobject response
