本地查詢的支持是不是在MongoDB中

Question

我是新來昆德拉MongoDB的啓用，我的問題是，當我試圖使用本機查詢來獲取數據我得到我下面的錯誤

Exception in thread "main" com.impetus.kundera.query.QueryHandlerException: java.lang.UnsupportedOperationException: Native query support is not enabled in mongoDB 
    at com.impetus.client.mongodb.query.MongoDBQuery.populateEntities(MongoDBQuery.java:172) 
    at com.impetus.kundera.query.QueryImpl.fetch(QueryImpl.java:986) 
    at com.impetus.kundera.query.QueryImpl.getResultList(QueryImpl.java:163) 
    at com.test.Test2.main(Test2.java:80) 

我的代碼如下

EntityManagerFactory emf = Persistence 
      .createEntityManagerFactory("mango"); 
    EntityManager em = emf.createEntityManager(); 

    Query query = em.createNativeQuery("db.resturant.find({contact: {\"$elemMatch\" : {\"Mobile\" : \"9568256549\"}}})"); 

query.getResultList(); 

幫助我......
