查看我的动态

一、MovementsController

 /**
     * 查看我的动态：
     * 请求路径：/movements/all
     * 请求方式：get
     * 请求参数：page，当前页码；pagesize，每页显示数；userId，用户id
     * 响应结果：PageResult
     */

    @GetMapping("/all")
    public ResponseEntity lookMyMovements(Long userId,
                                          @RequestParam(defaultValue = "1") Integer page,
                                          @RequestParam(defaultValue = "10") Integer pageSize){

        //1.直接调用业务层完成查看我的动态业务
        PageResult pageResult = movementsService.lookMyMovements(userId,page,pageSize);
        //2.构造返回值
        return ResponseEntity.ok(pageResult);
    }

二、MovementsService

/**
     *
     *查看我的动态
     */
    public PageResult lookMyMovements(Long userId, Integer page, Integer pageSize) {

        //1.调用api分页查询我的动态数据
        PageResult pageResult = movementsApi.lookMyMovements(userId,page,pageSize);
        //2.在PageResult里获取movements数据
        List<Movement> movements = (List<Movement>) pageResult.getItems();
        //3.判断movement是否为空,为空直接返回pageResult
        if(movements == null){
            return pageResult;
        }

        //4.调用userInfoA根据用户id查询用户详情

        UserInfo userInfo = userInfoApi.queryUserInfo(userId);

        List<MovementsVo> movementsVoList = new ArrayList<>();
        //5.遍历movements,每条动态构造一个vo对象
        for (Movement movement : movements) {
            MovementsVo movementsVo = MovementsVo.init(userInfo, movement);
            movementsVoList.add(movementsVo);
        }

        //5.构造返回值
        pageResult.setItems(movementsVoList);
        return pageResult;


    }

三、lookMyMovements

    /**
     *
     * 查看我的动态
     */
    public PageResult lookMyMovements(Long userId, Integer page, Integer pageSize) {
        //1.创建Criteria对象，设置查询条件
        Criteria criteria = Criteria.where("userId").is(userId);
        //2.根据criteria创建Query
        Query query = Query.query(criteria);
        query.skip(( page - 1 ) * pageSize ).limit(pageSize).with(Sort.by(Sort.Order.desc("created")));

        //3.调用mongoTemplate查询
        List<Movement> movements = mongoTemplate.find(query, Movement.class);


        //4.构造返回值
        PageResult pageResult = new PageResult(page,pageSize,0,movements);

        return pageResult;
    }

四、vo对象

package com.tanhua.model.vo;

import com.tanhua.model.domain.UserInfo;
import com.tanhua.model.mongo.Movement;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.beans.BeanUtils;
import org.springframework.util.StringUtils;

import java.io.Serializable;
import java.text.SimpleDateFormat;
import java.util.Date;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class MovementsVo  implements Serializable {

    private String id; //动态id

    private Long userId; //用户id
    private String avatar; //头像
    private String nickname; //昵称
    private String gender; //性别 man woman
    private Integer age; //年龄
    private String[] tags; //标签


    private String textContent; //文字动态
    private String[] imageContent; //图片动态
    private String distance; //距离
    private String createDate; //发布时间 如: 10分钟前
    private Integer likeCount; //点赞数
    private Integer commentCount; //评论数
    private Integer loveCount; //喜欢数


    private Integer hasLiked; //是否点赞（1是，0否）
    private Integer hasLoved; //是否喜欢（1是，0否）


    public static MovementsVo init(UserInfo userInfo, Movement item) {
        MovementsVo vo = new MovementsVo();
        //设置动态数据
        BeanUtils.copyProperties(item, vo);
        vo.setId(item.getId().toHexString());
        //设置用户数据
        BeanUtils.copyProperties(userInfo, vo);
        if(!StringUtils.isEmpty(userInfo.getTags())) {
            vo.setTags(userInfo.getTags().split(","));
        }
        //图片列表
        vo.setImageContent(item.getMedias().toArray(new String[]{}));
        //距离
        vo.setDistance("500米");
        Date date = new Date(item.getCreated());
        vo.setCreateDate(new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(date));
        //设置是否点赞(后续处理)
        vo.setHasLoved(0);
        vo.setHasLiked(0);
        return vo;
    }
}
