需求：

1、获取保存到mongodb库中的搜索记录列表

2、实现删除搜索记录接口

保存搜索记录数据参考上篇Mongodb：业务应用（1）_Success___的博客-CSDN博客

获取记录列表

 1、创建controller

package com.heima.search.controller.v1;import com.heima.model.common.dtos.ResponseResult;
import com.heima.search.service.ArticleSearchService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;@RestController
@RequestMapping("/api/v1/history")
public class SearchHistoryController {@AutowiredArticleSearchService articleSearchService;@PostMapping("/load")public ResponseResult getHistory(){return articleSearchService.getHistory();}}

2、service实现类

    /**查询搜索历史@return*/@Overridepublic ResponseResult getHistory() {//查询当前用户下面的搜索记录Integer userId = AppThreadLocalUtil.getUser().getId();//构造条件Query query = Query.query(Criteria.where("userId").is(userId));//执行查询List<ApUserSearch> list = mongoTemplate.find(query, ApUserSearch.class);//返回数据return ResponseResult.okResult(list);}

3、测试

        返回成功         

根据id删除搜索记录 

1、实现controller

    @PostMapping("/del")public ResponseResult delHistory(@RequestBody ApUserSearch userSearch){return articleSearchService.del(userSearch);}

2、service实现类

    /*根据id删除搜索记录*/@Overridepublic ResponseResult del(HistorySearchDto dto) {//检查参数if(dto == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}//检查登录状态Integer userId = AppThreadLocalUtil.getUser().getId();if(userId == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}//执行删除mongoTemplate.remove(Query.query(Criteria.where("userId").is(userId).and("id").is(dto.getId())),ApUserSearch.class);return ResponseResult.okResult(AppHttpCodeEnum.SUCCESS);}

3、测试
