如何使用Graphql SPQR实现查询过滤和排序？

import io.leangen.graphql.annotations.GraphQLArgument;
import io.leangen.graphql.annotations.GraphQLQuery;
import io.leangen.graphql.annotations.GraphQLNonNull;
import io.leangen.graphql.annotations.GraphQLTypeResolver;
import io.leangen.graphql.spqr.spring.annotations.GraphQLApi;
import io.leangen.graphql.spqr.spring.annotations.GraphQLApiConfig;
import io.leangen.graphql.spqr.spring.annotations.WithResolverBuilder;

import java.util.List;

@GraphQLApi
@GraphQLApiConfig(resolverBuilders = {
        @WithResolverBuilder(name = "Filtering", config = FilteringResolverBuilder.class),
        @WithResolverBuilder(name = "Sorting", config = SortingResolverBuilder.class)
})
public class MyGraphQLApi {

    @GraphQLQuery(name = "users")
    public List<User> getUsers(
            @GraphQLArgument(name = "filter") UserFilter filter,
            @GraphQLArgument(name = "sort") @GraphQLNonNull List<SortField> sortFields
    ) {
        // 根据过滤条件和排序字段从数据源中获取用户列表
        // 实现过滤和排序逻辑
        // 返回符合条件的用户列表
    }
}

@GraphQLTypeResolver(FilteringResolverBuilder.class)
public class UserFilter {
    // 定义过滤条件的属性
}

public class SortField {
    private String field;
    private SortOrder order;

    // 定义排序字段的属性和排序顺序
}

public enum SortOrder {
    ASCENDING,
    DESCENDING
}
