好友推荐列表分页查询

一、请求dto对象

package com.tanhua.model.dto;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

//推荐好友列表分页查询请求参数
@Data
@NoArgsConstructor
@AllArgsConstructor
public class RecommendUserDto {
   
   

    private Integer page = 1; //当前页数
    private Integer pagesize = 10; //页尺寸
    private String gender; //性别 man woman
    private String lastLogin; //近期登陆时间
    private Integer age; //年龄
    private String city; //居住地
    private String education; //学历
}

二、响应数据的模型对象

package com.tanhua.model.domain;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;
import java.util.Collections;
import java.util.List;

//列表翻页查询
@Data
@AllArgsConstructor
@NoArgsConstructor
public class PageResult implements Serializable {
   
   

    private Integer page;//当前页码
    private Integer pagesize;//每页显示数
    private Integer pages = 0;//总页数
    private Integer counts = 0;//总记录数

    private List<?> items = Collections.emptyList(); //列表

    public PageResult(Integer page,Integer pagesize,
                      int counts,List list) {
   
   
        this.page = page;
        this.pagesize = pagesize;
        this.items = list;
        this.counts = counts;
        this.pages = counts % pagesize == 0 ? counts / pagesize : counts / pagesize + 1;
    }

}

三、TanHuaController

package com.tanhua.server.controller;

import com.tanhua.model.domain.PageResult;
import com.tanhua.model.dto.RecommendUserDto;
import com.tanhua.model.vo.TodayBest;
import com.tanhua.server.service.TanHuaService;
import org.springframework.beans.factory.annotation.Autowired
