转换成java语句是？

以下是将该Elasticsearch查询语句转换成Java语句的示例代码：

import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.index.query.BoolQueryBuilder;
import org.elasticsearch.index.query.MatchQueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.search.aggregations.AggregationBuilders;
import org.elasticsearch.search.aggregations.bucket.composite.CompositeAggregationBuilder;
import org.elasticsearch.search.aggregations.bucket.filter.BucketSelectorPipelineAggregationBuilder;
import org.elasticsearch.search.aggregations.bucket.terms.TermsAggregationBuilder;
import org.elasticsearch.search.builder.SearchSourceBuilder;
import org.elasticsearch.search.fetch.subphase.FetchSourceContext;
import org.elasticsearch.search.sort.SortOrder;

import java.io.IOException;

public class ESQueryExample {
    public static void main(String[] args) throws IOException {
        // 创建ES客户端
        RestHighLevelClient client = new RestHighLevelClient();

        // 构建布尔查询
        BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
        MatchQueryBuilder matchQuery1 = QueryBuilders.matchQuery("erpSupplierFlowId", "1001E111230001IPJP6W");
        MatchQueryBuilder matchQuery2 = QueryBuilders.matchQuery("erpSupplierFlowId", "1001A110000001CBWJ0I");
        boolQuery.should(matchQuery1).should(matchQuery2);

        // 构建复合聚合
        CompositeAggregationBuilder compositeAgg = AggregationBuilders.composite("my_buckets", 
                new TermsAggregationBuilder("erpGoodsId").field("erpGoodsId").order(SortOrder.ASC),
                new TermsAggregationBuilder("batchNum").field("batchNum").order(SortOrder.ASC),
                new TermsAggregationBuilder("wmsProductCode").field("wmsProductCode").missingBucket(true).order(SortOrder.ASC))
                .size(10);

        // 构建聚合过滤器
        BucketSelectorPipelineAggregationBuilder filterAgg = AggregationBuilders.bucketSelector("filter_empty_dest", "_count != null");

        // 构建查询请求
        SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
        sourceBuilder.query(boolQuery);
        sourceBuilder.aggregation(compositeAgg.subAggregation(filterAgg));
        sourceBuilder.size(0);
        sourceBuilder.trackTotalHits(false);
        sourceBuilder.fetchSource(new FetchSourceContext(false));

        // 执行查询请求
        client.search(sourceBuilder, RequestOptions.DEFAULT);

        // 关闭ES客户端
        client.close();
    }
}

需要注意的是，该示例代码中的ES客户端、查询条件等细节可能需要根据实际情况进行修改。
