报警数据过滤及处理:
报警数据:
一旦有了报警数据之后,可能需要通知多个人,咱们要为每一个要通知的人保存一条报警数据告警数据表结构:alert_data
如果若依的生成代码功能将代码添加到项目当中
查询老人异常数据要通知的护理员:
DeviceMapper:
/*** 根据随身设备id查询老人关联的护理人员id列表* @param iotId 设备id* @return 护理人员列表*/
List<Long> selectNursingIdsByIotIdWithElder(@Param("iotId") String iotId);/*** 根据固定设备id查询老人关联的护理人员id列表* @param iotId 设备id* @return 护理人员列表*/
List<Long> selectNursingIdsByIotIdWithBed(@Param("iotId") String iotId);
DeviceMapper.xml:
<select id="selectNursingIdsByIotIdWithElder" resultType="java.lang.Long">select ne.nursing_idfrom device dleft join nursing_elder ne on ne.elder_id = d.binding_locationwhere d.location_type = 0and d.iot_id = #{iotId}
</select>
<select id="selectNursingIdsByIotIdWithBed" resultType="java.lang.Long">select ne.nursing_idfrom device dleft join elder e on e.bed_id = d.binding_locationleft join nursing_elder ne on ne.elder_id = e.idwhere d.location_type = 1 and d.physical_location_type = 2and d.iot_id = #{iotId}
</select>
通过角色名称查询用户id:
system模块下SysUserRoleMapper:
@Select("select sur.user_id from sys_user_role sur left join sys_role sr on sur.role_id = sr.role_id where sr.role_name = #{roleName}")
List<Long> selectUserIdByRoleName(String roleName);
定时任务:
platform模块下task包下创建AlertTask类:
package com.zzyl.nursing.task;import com.zzyl.nursing.service.IAlertRuleService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;@Component
@Slf4j
public class AlertTask {@Autowiredprivate IAlertRuleService alertRuleService;public void deviceDataAlertFilter() {alertRuleService.alertFilter();}
}
需要在后台管理系统中创建定时任务:
0 * * * * ?
表示每分钟整执行一次
AlertRuleService:
/*** 过滤报警*/
void alertFilter();
AlertRuleServiceImpl:
