mongo spring如何根据嵌套数组中的值对结果进行排序

import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.aggregation.Aggregation;
import org.springframework.data.mongodb.core.aggregation.AggregationOperation;
import org.springframework.data.mongodb.core.aggregation.AggregationResults;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;

import java.util.Arrays;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        MongoTemplate mongoTemplate = new MongoTemplate(); // 初始化MongoTemplate

        // 创建聚合操作
        AggregationOperation unwind = Aggregation.unwind("nestedArray"); // 展开嵌套数组
        AggregationOperation sort = Aggregation.sort("nestedArray.value"); // 根据嵌套数组中的值进行排序
        Aggregation aggregation = Aggregation.newAggregation(unwind, sort);

        // 执行聚合操作
        AggregationResults<Document> results = mongoTemplate.aggregate(aggregation, "collectionName", Document.class);

        // 获取排序后的结果
        List<Document> sortedDocuments = results.getMappedResults();
        for (Document document : sortedDocuments) {
            System.out.println(document);
        }
    }
}
