MongoTemplate: sum values of keys for documents matching a certain criterion
You are missing a closing parenthesis for the match() parameter:
import static org.springframework.data.mongodb.core.aggregation.Aggregation.*;Aggregation agg = Aggregation.newAggregation( match(Criteria.where("mobile").is("1234567890")), // <-- missing closing parenthesis group("mobile").sum("calls").as("totalCalls"), project("totalCalls") );AggregationResults<Doc> results = mongoTemplate.aggregate(agg, "yoCollection", Doc.class);Doc doc = results.getMappedResults().get(0);
