尚医通

版本：V1.0

一、就医提醒

我们通过定时任务，每天8点执行，提醒就诊

1 、搭建定时任务模块service-task

1.1 搭建service-task服务

搭建方式如service-user

1.2 修改配置pom.xml

<dependencies> <dependency> <groupId>com.atguigu</groupId> <artifactId>rabbit_util</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency></dependencies>


说明：引入依赖

1.3 添加配置文件

1、applicationproperties

# 服务端口server.port=8207# 服务名spring.application.name=service-task# 环境设置：dev、test、prodspring.profiles.active=dev
# nacos服务地址spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848
#rabbitmq地址spring.rabbitmq.host=192.168.44.165spring.rabbitmq.port=5672spring.rabbitmq.username=guestspring.rabbitmq.password=guest

1.4 添加启动类

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//取消数据源自动配置@EnableDiscoveryClientpublic class ServiceTaskApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceTaskApplication.class, args);
}
}

1.5 添加常量配置

在rabbit-util模块com.atguigu.yygh.common.constant.MqConst类添加

public static final String EXCHANGE_DIRECT_TASK = “exchange.direct.task”;public static final String ROUTING_TASK_8 = “task.8”;//队列public static final String QUEUE_TASK_8 = “queue.task.8”;

1.6 添加定时任务

Cron表达式
定时任务与统计 - 图1

| @Component
@EnableSchedulingpublic class ScheduledTask {

@Autowired<br />    **private **RabbitService **rabbitService**;

_/**<br />     * 每天8点执行 提醒就诊     */<br />    //@Scheduled(cron = "0 0 1 * * ?")<br />    _@Scheduled(cron = **"0/30 * * * * ?"**)<br />    **public void **task1() {<br />        **rabbitService**.sendMessage(MqConst.**_EXCHANGE_DIRECT_TASK_**, MqConst.**_ROUTING_TASK_8_**, **""**);<br />    }<br />} |

2、添加就医提醒处理

操作模块service-order

2.1 添加service接口

在OrderService类添加接口

| _/**

  • 就诊提醒 /
    _*void     patientTips(); | | —- |

2.2 添加service接口实现类

在OrderServiceImpl类添加接口实现

@Overridepublic void patientTips() {
QueryWrapper queryWrapper = new QueryWrapper<>();
queryWrapper.eq(“reserve_date”,new DateTime().toString(“yyyy-MM-dd”));
List orderInfoList = baseMapper.selectList(queryWrapper);
for(OrderInfo orderInfo : orderInfoList) {
//短信提示
_MsmVo msmVo = new MsmVo();
msmVo.setPhone(orderInfo.getPatientPhone());
String reserveDate = new DateTime(orderInfo.getReserveDate()).toString(“yyyy-MM-dd”) + (orderInfo.getReserveTime()==0 ? “上午”: “下午”);
Map param = new HashMap(){{
put(“title”, orderInfo.getHosname()+“|”+orderInfo.getDepname()+“|”+orderInfo.getTitle());
put(“reserveDate”, reserveDate);
put(“name”, orderInfo.getPatientName());
}};
msmVo.setParam(param);
rabbitService.sendMessage(MqConst.**_EXCHANGE_DIRECT_MSM, MqConst.ROUTING_MSM_ITEM**, msmVo);
}
}

2.3 添加mq监听

添加OrderReceiver 类

| @Componentpublic class OrderReceiver {

@Autowired<br />    **private **OrderService **orderService**;

@RabbitListener(bindings = @QueueBinding(<br />            value = @Queue(value = MqConst.**_QUEUE_TASK_8_**, durable = **"true"**),<br />            exchange = @Exchange(value = MqConst.**_EXCHANGE_DIRECT_TASK_**),<br />            key = {MqConst.**_ROUTING_TASK_8_**}<br />    ))<br />    **public void **patientTips(Message message, Channel channel) **throws **IOException {<br />        **orderService**.patientTips();<br />    }<br />} |

二、预约统计

我们统计医院每天的预约情况，通过图表的形式展示，统计的数据都来自订单模块，因此我们在该模块封装好数据，在统计模块通过feign的形式获取数据。
我们为什么需要一个统计模块呢，因为在实际的生成环境中，有很多种各式统计，数据来源于各个服务模块，我们得有一个统计模块来专门管理

1、ECharts

1.1简介

ECharts是百度的一个项目，后来百度把Echart捐给apache，用于图表展示，提供了常规的折线图、柱状图、散点图、饼图、K线图，用于统计的盒形图，用于地理数据可视化的地图、热力图、线图，用于关系数据可视化的关系图、treemap、旭日图，多维数据可视化的平行坐标，还有用于 BI 的漏斗图，仪表盘，并且支持图与图之间的混搭。
官方网站：https://echarts.apache.org/zh/index.html

1.2基本使用

（1）引入ECharts


（2）定义图表区域


（3）渲染图表（折线图）


（4）渲染图表（柱状图）


1.3项目中集成ECharts

npm install —save echarts@4.1.0

2、获取医院每天平台预约数据接口

操作模块：service-order

2.1添加Mapper接口

1、在OrderInfoMapper类添加接口

public interface OrderMapper extends BaseMapper {
List selectOrderCount(@Param(“vo”) OrderCountQueryVo orderCountQueryVo);
}


1、在OrderInfoMapper.xml文件添加方法

<?xml version=”1.0” encoding=”UTF-8” ?><!DOCTYPE mapper PUBLIC “-//mybatis.org//DTD Mapper 3.0//EN” “http://mybatis.org/dtd/mybatis-3-mapper.dtd"_>_<mapper namespace=”com.atguigu.yygh.order.mapper.OrderMapper”>
<select id=”selectOrderCount” resultType=”com.atguigu.yygh.vo.order.OrderCountVo”> select reservedate as reserveDate, _count(reserve_date) as count
from order_info
<where> <if test=”vo.hosname != null and vo.hosname != ‘’”> and hosname like CONCAT(‘%’,#{vo.hosname},’%’)
</if> <if test=”vo.reserveDateBegin != null and vo.reserveDateBegin != ‘’”> and reserve_date >= #{vo.reserveDateBegin}
</if> <if test=”vo.reserveDateEnd != null and vo.reserveDateEnd != ‘’”> and reserve_date <= #{vo.reserveDateEnd}
</if> and is_deleted = 0
</where> group by reserve_date
order by reserve_date
</select></mapper>


添加application.properties配置

mybatis-plus.mapper-locations=classpath:com/atguigu/yygh/order/mapper/xml/*.xml

2.2添加service接口

在OrderService类添加接口

_/
* 订单统计 */_Map getCountMap(OrderCountQueryVo orderCountQueryVo);

2.3添加service接口实现

在OrderServiceImpl类添加实现

| @Overridepublic Map getCountMap(OrderCountQueryVo orderCountQueryVo) {
Map map = new HashMap<>();

List<OrderCountVo> orderCountVoList<br />= **baseMapper**.selectOrderCount(orderCountQueryVo);<br />    _//日期列表<br />    _List<String> dateList<br />=orderCountVoList.stream().map(OrderCountVo::getReserveDate).collect(Collectors._toList_());<br />    _//统计列表<br />    _List<Integer> countList<br />=orderCountVoList.stream().map(OrderCountVo::getCount).collect(Collectors._toList_());<br />    map.put(**"dateList"**, dateList);<br />    map.put(**"countList"**, countList);<br />    **return **map;<br />} |

| —- |

2.4添加controller方法

在OrderApiController类添加方法

@ApiOperation(value = “获取订单统计数据”)@PostMapping(“inner/getCountMap”)public Map getCountMap(@RequestBody OrderCountQueryVo orderCountQueryVo) {
return orderService.getCountMap(orderCountQueryVo);
}

3、添加feign方法

创建模块：service-order-client

3.1添加feign接口

添加接口和方法

| @FeignClient(value = “service-order”)@Repositorypublic interface OrderFeignClient {
/
* 获取订单统计数据 */
@PostMapping(“/api/order/orderInfo/inner/getCountMap”)
Map getCountMap(@RequestBody OrderCountQueryVo orderCountQueryVo);

} | | —- |

4、搭建service-statistics

4.1搭建service-statistics服务

搭建方式如service-user

4.2修改配置pom.xml

<dependencies> <dependency> <groupId>com.atguigu</groupId> <artifactId>service_order_client</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency></dependencies>

4.3添加配置文件

1、application.properties

# 服务端口server.port=8208# 服务名spring.application.name=service-statistics# 环境设置：dev、test、prodspring.profiles.active=dev
# nacos服务地址spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

4.4添加启动类

| @SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//取消数据源自动配置@EnableDiscoveryClient
@EnableFeignClients
@ComponentScan(basePackages = {“com.atguigu”})public class ServiceStatisticsApplication {

**public static void **main(String[] args) {<br />        SpringApplication._run_(ServiceStatisticsApplication.**class**, args);<br />    }

} | | —- |

4.5添加controller方法

| @Api(tags = “统计管理接口”)@RestController
@RequestMapping(“/admin/statistics”)public class StatisticsController {

@Autowired<br />    **private **OrderFeignClient **orderFeignClient**;

@ApiOperation(value = **"获取订单统计数据"**)<br />    @GetMapping(**"getCountMap"**)<br />    **public **Result getCountMap(@ApiParam(name = **"orderCountQueryVo"**, value = **"查询对象"**, required = **false**) OrderCountQueryVo orderCountQueryVo) {<br />        **return **Result._ok_(**orderFeignClient**.getCountMap(orderCountQueryVo));<br />    }<br />} |

5、前端展示

5.1添加路由

在 src/router/index.js 文件添加路由

{
path: ‘/statistics’,
component: Layout,
redirect: ‘/statistics/order/index’,
name: ‘BasesInfo’,
meta: { title: ‘统计管理’, icon: ‘table’ },
alwaysShow: true,
children: [
{
path: ‘order/index’,
name: ‘预约统计’,
component: () =>import(‘@/views/statistics/order/index’),
meta: { title: ‘预约统计’ }
}
]
},

5.2封装api请求

创建/api/statistics/orderStatistics.js

import request from ‘@/utils/request’

const api_name = ‘/admin/statistics’

export default {

getCountMap(searchObj) {
return request({
url: ${api_name}/getCountMap,
method: ‘get’,
params: searchObj
})
}
}

5.3添加组件

创建/views/statistics/order/index.vue组件
