具有Aggreagtion的MongoDB本机查询可在Java中进行查询

Question

我有本地Mongo查询

[
{
    $match: {
        createdById: "5c3cac81989a8469d435f3b2"
    }
}, {
    $group: {
        _id: "$uID",
        latest: {
            $max: "$latest"
        },
        createdById: {
            $first: "$createdById"
        }
    }
}
]

存储库

Page<NetworkObject> findByCreatedById(String userId, Pageable pageable);

我这样尝试过

@Query(value = "[ {'$match': {'createdById': ?#{[0]} }}, {'$group': {'_id': '$uID', 'latest': {'$max': '$latest'}, 'createdById': {'$first': '$createdById'}}}]"
Page<NetworkObject> findByCreatedById(String userId, Pageable pageable);

但我有一个错误

org.bson.BsonInvalidOperationException: readStartDocument can only be called when CurrentBSONType is DOCUMENT, not when CurrentBSONType is ARRAY.

似乎我必须更改为聚合查询，但是我还没有使用它。

更新
创建聚合

Aggregation aggregation = newAggregation(match(Criteria.where("createdById").is(userId)),
                group(fields("uID").and("latest","$latest")
                        .and("createdById","$createdById"))
                        .max("$latest").as("latest")
                        .first("$createdById").as("createdById"));
        AggregationResults<NetworkObject> results = mongoTemplate.aggregate(aggregation,"NetworkObject",NetworkObject.class);
        List<NetworkObject> objects = Optional.of(results.getMappedResults()).get();

但这会通过createdById返回所有集合元素。
