高校健康上报系统设计与实现

0. 大作业讲解视频在根目录下

1. 项目介绍

在全国人民共同抗击新冠肺炎疫情的严峻形势下,为使高校师生健康信息及时汇报,便于了解健康状况,做好高校师生内部疫情防控和管理工作,特别设计开发高校健康上报系统。

2. 需求分析

2.1 前端界面功能模块

  1. 界面美观、简洁、主题统一;
  2. 调研国内相关系统界面的输入信息,设计前端各信息录入项目;
  3. 有防止用户重复提交的功能;
  4. 有加速渲染前端界面的设计。

2.2 后端管理端功能

  1. 使用 Vue + ElementUI 实现管理后台各个功能界面;
  2. 界面简洁,主题统一;
  3. 管理员账号管理模块;
  4. 使用Spring Security安全框架实现认证、访问控制;
  5. 账号管理模块,可以锁定账号;
  6. 有解决系统高并发问题的设计;
  7. 提供大数据报表并导出Excel表格,相关人员通过报表可以一目了然查看相关信息;
  8. 所有列表可以进行综合查询,特别是时间字段,并可以排序;
  9. 所有列表可以导出excel文件或者pdf文件;
  10. 接入莞工中央认证
  11. 后台登录使用自定义图形验证码

3. 数据库设计

3.1 中央认证表

注:该表保存通过中央认证登录的用户信息【用于填写健康上报表单前的登录认证】

3.2 管理员表

3.3 健康上报表

4. 前端设计

使用技术栈:Vue + ElementUI + axios + VueX + Echart

4.1 健康上报表单设计

健康上报表单代码仓库:https://gitee.com/alizipeng/health-system-front

4.2 中台管理系统设计

中台管理系统代码仓库:https://gitee.com/alizipeng/health-system-middle

5. 后端设计

5.1 技术方案

(1)开发框架:Spring Boot、Mybatis-plus

(2)项目构建工具:Maven

(3)权限控制:Spring Security。用于对登录的用户认证授权,进行访问控制。

(4)数据缓存/NoSQL:Redis。用于缓存常用数据,如省份数据等;以及做一些NoSQL查询;使用Redis防止消息重复消费

(5)消息队列:RabbitMQ。用于异步导出查询数据,将数据导出与主业务进行 解耦 。可将数据导出模块单独部署,当数据量很大时,可以防止导出模块与主业务模块抢夺服务器资源。同时使用了 延时队列 来删除过期的导出文件。

(6)数据导出:利用MyBatis的动态SQL功能,首先传入参数生成完整SQL,再把SQL发送到队列中,等待消费者进行消费。

5.2 多模块项目结构

5.3 权限模块设计

} ```

5.4 数据导出模块设计

5.4.1 消息队列部分设计

分为两个消费者:

DataStatsTaskReceiver 的功能为 1. 执行SQL并导出Excel文件,然后把文件上传到七牛云中,再将任务状态更新为成功,客户端便可下载文件; 2. 成功导出文件后,会给文件设置一个有效期,过期之后将从七牛云删除。具体实现为发送延时消息到延迟队列中。

DelayTaskReceiver 为延迟队列的消费者,功能为接收 DataStatsTaskReceiver 发送过来的文件ID,等到有效期到达之后,会对文件进行删除。具体实现为使用了RabbitMQ延时队列插件。

DataStatsTaskReceiver 实现: ```java @RabbitListener(queues = DataStatsTaskQueueConstants.STATS_TASK_QUEUE_NAME) public void handler(Message message, Channel channel) throws IOException { DataStatsTask dataStatsTask = (DataStatsTask) message.getPayload(); MessageHeaders headers = message.getHeaders(); Long tag = (Long) headers.get(AmqpHeaders.DELIVERY_TAG); String msgId = (String) headers.get("spring_returned_message_correlation"); logger.info("Received Task:{}",dataStatsTask.toString()); // 设置唯一消息id,防止重复消费 if (redisTemplate.opsForHash().entries("stats_task_log").containsKey(msgId)) { //redis 中包含该 key,说明该消息已经被消费过 logger.info(msgId + ":消息已经被消费"); channel.basicAck(tag, false);//确认消息已消费 return; } String sql = dataStatsTask.getSql(); String key = dataStatsTask.getTaskId(); // 在redis中设置该任务的状态 redisTemplate.opsForHash().put("export_task",dataStatsTask.getTaskId(),"processing"); if(dbUtil.extractToExcel(sql,path,key)){ String local = path+key; String url = QiNiuUtil.upload(local,key); if(url==null){ redisTemplate.opsForHash().delete("export_task",dataStatsTask.getTaskId()); return; } redisTemplate.opsForHash().put("export_task",dataStatsTask.getTaskId(),url); // 发送延时任务 sendDelayTask(key,dataStatsTask.getExpired()); } } /* * 发送延时任务,msg为id,delayTime为文件有效期 / public void sendDelayTask(String msg,Integer delayTime){ rabbitTemplate.convertAndSend(DelayDeleteQueueConstants.DELAY_DELETE_EXCHANGE_NAME, DelayDeleteQueueConstants.DELAY_DELETE_ROUTING_KEY_NAME, msg, a ->{ a.getMessageProperties().setDelay(delayTime); return a; }); }

`DelayTaskReceiver`配置: java @Configuration public class DelayedRabbitMQConfig {

@Bean
public Queue immediateQueue() {
    return new Queue(DelayDeleteQueueConstants.DELAY_DELETE_QUEUE_NAME);
}

@Bean
public CustomExchange customExchange() {
    Map<String, Object> args = new HashMap<>();
    args.put("x-delayed-type", "direct");
    return new CustomExchange(DelayDeleteQueueConstants.DELAY_DELETE_EXCHANGE_NAME,
            "x-delayed-message", true, false, args);
}

@Bean
public Binding bindingNotify(@Qualifier("immediateQueue") Queue queue,
                             @Qualifier("customExchange") CustomExchange customExchange) {
    return BindingBuilder.bind(queue).to(customExchange)
            .with(DelayDeleteQueueConstants.DELAY_DELETE_ROUTING_KEY_NAME).noargs();
}

}

`DelayTaskReceiver`实现: java @RabbitListener(queues = DelayDeleteQueueConstants.DELAY_DELETE_QUEUE_NAME) public void handler(Message message, Channel channel) throws IOException { String taskId = String.valueOf(message.getPayload()); logger.debug("delete expired task:{}",taskId); QiNiuUtil.deleteFile(taskId); redisTemplate.opsForHash().delete("export_task",taskId); } ```

5.4.2 数据导出工具类

执行SQL,然后导出为Excel,会自动添加表头 ```java

public boolean extractToExcel(String sql,String path,String fileName){ try { ResultSet resultSet = execute(sql); ResultSetMetaData resultSetMetaData = resultSet.getMetaData(); List > ret = new ArrayList<>(); List header = new ArrayList<>(); int colCount = resultSetMetaData.getColumnCount(); for(int i=1;i<=colCount;i++) header.add(resultSetMetaData.getColumnName(i)); // 添加表头 ret.add(header); while (resultSet.next()){ List row = new ArrayList<>(); for(int i=1;i<=colCount;i++) row.add(resultSet.getObject(i)); ret.add(row); } DataToExcel.ToExcel(ret,path,fileName); } catch (SQLException throwables) { throwables.printStackTrace(); return false; } return true; } 以下为生成SQL代码: java / * 运行期获取MyBatis执行的SQL及参数 * * @param id Mapper xml 文件里的select Id * @param obj 参数 * @param sqlSessionFactory * @return / public static String getMyBatisSql(String id, Object obj, SqlSessionFactory sqlSessionFactory) { MappedStatement ms = sqlSessionFactory.getConfiguration().getMappedStatement(id); BoundSql boundSql = ms.getBoundSql(obj); String sql = boundSql.getSql(); List parameterMappings = boundSql.getParameterMappings(); if (parameterMappings != null) { Object[] parameterArray = new Object[parameterMappings.size()]; ParameterMapping parameterMapping = null; Object value = null; Object parameterObject = null; MetaObject metaObject = null; PropertyTokenizer prop = null; String propertyName = null; String[] names = null; for (int i = 0; i < parameterMappings.size(); i++) { parameterMapping = parameterMappings.get(i); if (parameterMapping.getMode() != ParameterMode.OUT) { propertyName = parameterMapping.getProperty(); names = propertyName.split("\."); if (propertyName.indexOf(".") != -1 && names.length == 2) { parameterObject = boundSql.getAdditionalParameter(names[0]); propertyName = names[1]; } else if (propertyName.indexOf(".") != -1 && names.length == 3) { parameterObject = boundSql.getAdditionalParameter(names[0]); // map if (parameterObject instanceof Map) { parameterObject = ((Map) parameterObject).get(names[1]); } propertyName = names[2]; } else { parameterObject = boundSql.getAdditionalParameter(propertyName); } if (null == parameterObject) { parameterObject = getFieldValueByFieldName(propertyName, obj); } prop = new PropertyTokenizer(propertyName); if (parameterObject == null) { value = null; } else if (ms.getConfiguration().getTypeHandlerRegistry().hasTypeHandler(parameterObject.getClass())) { value = parameterObject; } else if (boundSql.hasAdditionalParameter(propertyName)) { value = boundSql.getAdditionalParameter(propertyName); } else if (propertyName.startsWith(ForEachSqlNode.ITEM_PREFIX) && boundSql.hasAdditionalParameter(prop.getName())) { value = boundSql.getAdditionalParameter(prop.getName()); } else { value = metaObject == null ? null : metaObject.getValue(propertyName); } parameterArray[i] = value; } parameterObject = null; } int i = 0; while (sql.indexOf("?") != -1) { if (null == parameterArray[i]) { throw new RuntimeException("mybatis获取sql异常"); } if (parameterArray[i] instanceof String) { sql = sql.replaceFirst("\?", "'" + parameterArray[i].toString() + "'"); } else { sql = sql.replaceFirst("\?", parameterArray[i].toString()); } i++; } int index; StringBuilder sb = new StringBuilder(); for (String s : sql.split("\n")) { index = s.indexOf("--"); if (-1 == index) { index = s.length(); } sb.append(s.substring(0, index).replace("\t", " ").trim()).append(" "); } return sb.toString().replaceAll("(\r?\n(\s \r?\n)+)", " ").replaceAll("\n", " ").replaceAll("\r", " ").replaceAll(" ", " ").replaceAll(" ", " ").replaceAll(" ", " ");

    }
    return sql;
}

Controller调用代码: java @GetMapping("/stats/temperature") public ResultVo getStatsTemperature(@RequestParam("temperature")float temperature, @RequestParam("time")String time) { SqlSessionFactory sqlSessionFactory = null; try { sqlSessionFactory = new SqlSessionFactoryBuilder().build(Resources.getResourceAsStream("stats-mybatis.xml")); } catch (IOException e) { e.printStackTrace(); return ResultUtils.error("Server error"); } TemperStatsParam sParam = new TemperStatsParam(); sParam.setTemperature(temperature); sParam.setTime(time); String sql = MybatisSQLUtil.getMyBatisSql("StatsMapper.getTemperStats", sParam, sqlSessionFactory); DataStatsTask dataStatsTask = new DataStatsTask(UUID.randomUUID().toString()+".xls", sql,60000); sendDataStatsTask(dataStatsTask); return ResultUtils.success(dataStatsTask.getTaskId()); } ``` Mapper:
