1.新建dto类

@Data
public class Entity implements Serializable {
    private static final long serialVersionUID = 1L;
    private String findDate;
    private Integer virusCount;
}

2.dao

List<Entity> queryVirusPage(Page<Entity> page, Map<String, Object> params);

3.mapper.xml

    <resultMap id="virusCountMap" type="com.guorui.modules.ext.dto.Entity">
        <result property="findDate" column="find_date"/>
        <result property="virusCount" column="virus_count"/>
    </resultMap>
	
    <select id="queryVirusPage" parameterType="map" resultMap="virusCountMap">
        select DATE_FORMAT(find_time,'%Y-%m-%d') find_date,count(id) virus_count
        from vir_virus_info as v
        WHERE 1=1
        group by find_date
        order by find_date desc
    </select>

4.Service类

List<Entity> queryVirusPage(Page<Entity> page, Map<String, Object> params);

5.ServiceImpl

public List<Entity> queryVirusPage(Page<Entity> page, Map<String, Object> params){

       return baseMapper.queryVirusPage(page, params);
}

6.controller

public R selectCount(@RequestParam Map<String, Object> params) {
        int current = TryParse.parseInt(params.get("page"));
        int limit = TryParse.parseInt(params.get("limit"));
		
        Page<Entity> page = new Page<Entity>(current, limit);
        List<Entity> pageList = virusInfoService.queryVirusPage(page, params);
        page.setRecords(pageList);
		
        return R.ok().put("page", page);
}
