title: Spring data mongodb query by json string
body: <p>My code need to support any query that being sent by the client . The client will be sending the query as a json . I have done this using java mongo driver low level api using following code , <br/><code>BasicDBObject queryObject = (BasicDBObject) JSON.parse(whereJson.toString());</code>
  <br/>As i am a newbie in spring data mongodb , i am unable to find a similar solution in either Query or Criteria classes . I have checked different tutorials and couldn't find any . Is it possible to do in spring data mongodb or should i use low level apis itself ?</p>
