java - Spring 数据蒙戈: BSON field name can not be null

Question

我有一个在 mongo 中运行良好的函数:

db.getCollection('TrainingSession').aggregate(
    {
      "$group":{
       "_id": {  
         "$year":"$startDate"
          },
         "totalPrice": {"$sum": "$billing.price.amount"},
         "totalExtra":  {"$sum": "$billing.extra.amount"},
         "nbOfSession": { "$sum": 1 }

      }
     }, 
     {
         "$match": {
         "_id": 2016
         }
     },
      {  
       "$project":{  
          "nbOfSession":1,
           "total": { "$add": ["$totalPrice", "$totalExtra" ] }
       }
    }

    );

我尝试在 Spring 中实现它，但出现错误。这是java代码:

@Override
public RevenueDTO getRevenuesByYear(int year) {
    Aggregation aggregation = Aggregation.newAggregation(
            project().andExpression("year(startDate)").as("year").andInclude("billing"),
            match(Criteria.where("year").is(year)),
            group("year").sum("billing.price.amount").as("totalPrice").sum("billing.extra.amount").as("totalExtra").count().as("nbOfSessions"),
            project().andInclude("nbOfSessions").andExpression("add(totalPrice, totalExtra)").as("total"));
    return mongoTemplate.aggregate(aggregation, TrainingSession.class, RevenueDTO.class).getUniqueMappedResult();

}

这是错误:

{
  "timestamp": 1481294809990,
  "status": 500,
  "error": "Internal Server Error",
  "exception": "java.lang.IllegalArgumentException",
  "message": "BSON field name can not be null",
  "path": "/api/sessions/revenues/2016"
}

感谢一位 friend ，它是这样工作的:

Aggregation aggregation = newAggregation(
            project("billing")
                    .andExpression("year(startDate)").as("year"),
            match(where("year").is(year)),
            group("year")
                    .sum("billing.price.amount").as("totalPrice")
                    .sum("billing.extra.amount").as("totalExtra")
                    .count().as("nbOfSessions"),
            project("nbOfSessions")
                    .andExpression("totalPrice + totalExtra").as("total")
