有没有使用Spring Reactive来读取ElasticSearch索引的所有文档的示例？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

implementation 'org.springframework.boot:spring-boot-starter-data-elasticsearch'

import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.repository.ReactiveElasticsearchRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface DocumentRepository extends ReactiveElasticsearchRepository<DocumentEntity, String> {
    Flux<DocumentEntity> findAll();
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import reactor.core.publisher.Flux;

@Service
public class DocumentService {
    private final DocumentRepository documentRepository;

    @Autowired
    public DocumentService(DocumentRepository documentRepository) {
        this.documentRepository = documentRepository;
    }

    public Flux<DocumentEntity> getAllDocuments() {
        return documentRepository.findAll();
    }
}
