1.指定查询哪些字段

方式一:

        Query query = new Query();
        query.fields().include("booking"); //包含该字段
        query.fields().exclude("salary");//不包含该字段
  　　　 Booking booking = mongoTemplate.findOne(query, Booking.class);

    @Test
    public void testName11() throws Exception {
        
             Query query = Query.query(Criteria.where("bookingNo").is("UFL-BK2020070711530323920"));
             Booking booking = new Booking();
            query.fields().include("bookingNo");
            query.fields().include("milestoneStatus");
            query.fields().include("bookingDateLoc");

            List<Booking> bookingList = mongoTemplate.find(query, Booking.class);
            System.err.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
            System.err.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
            System.err.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
            System.err.println(JSON.toJSONString(bookingList));

 

 

方式2:

        QueryBuilder queryBuilder = new QueryBuilder(); 
        queryBuilder.or(new BasicDBObject("onumber", "002"), new BasicDBObject("cname","zcy1")); 
        BasicDBObject fieldsObject=new BasicDBObject();
        fieldsObject.put("onumber", 1);
        fieldsObject.put("cname", 1);
       Query query=new BasicQuery(queryBuilder.get(),fieldsObject)
