mongo聚合字符串类型的数字进行排序

• 设置collation

Collation collation = Collation.of(Locale.CHINESE)
                .numericOrdering(true);

• 设置聚合选项

Aggregation aggregation = Aggregation.newAggregation(
                Aggregation.match(orOperator),

        ).withOptions(AggregationOptions.builder()
                        .collation(collation)
                .build());
