如何为MongoDB的ReactiveCrudRepository增加batchSize？

import org.springframework.data.mongodb.core.ReactiveMongoTemplate;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.repository.support.ReactiveMongoRepositoryFactory;
import org.springframework.data.repository.reactive.ReactiveCrudRepository;

public interface CustomReactiveCrudRepository<T, ID> extends ReactiveCrudRepository<T, ID> {
    // 自定义方法
}

public class CustomReactiveMongoRepositoryFactory extends ReactiveMongoRepositoryFactory {
    private final ReactiveMongoTemplate reactiveMongoTemplate;

    public CustomReactiveMongoRepositoryFactory(ReactiveMongoTemplate reactiveMongoTemplate) {
        super(reactiveMongoTemplate);
        this.reactiveMongoTemplate = reactiveMongoTemplate;
    }

    @Override
    protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
        return CustomReactiveCrudRepository.class;
    }

    @Override
    protected Optional<Query> getQuery(Class<?> type) {
        Query query = super.getQuery(type).orElse(new Query());
        query.batchSize(100); // 设置batchSize的值
        return Optional.of(query);
    }
}

// 在应用程序中使用自定义的ReactiveMongoTemplate对象
@Configuration
@EnableReactiveMongoRepositories(repositoryFactoryBeanClass = CustomReactiveMongoRepositoryFactory.class)
public class AppConfig extends AbstractReactiveMongoConfiguration {
    @Override
    public MongoClient reactiveMongoClient() {
        // 创建MongoClient对象
    }

    @Override
    protected String getDatabaseName() {
        // 返回数据库名称
    }

    @Bean
    public ReactiveMongoTemplate reactiveMongoTemplate() {
        return new ReactiveMongoTemplate(reactiveMongoClient(), getDatabaseName());
    }
}
