体检预约

体检预约流程

用户可以通过如下操作流程进行体检预约：

1、在移动端首页点击体检预约，页面跳转到套餐列表页面

2、在套餐列表页面点击要预约的套餐，页面跳转到套餐详情页面

3、在套餐详情页面点击立即预约，页面跳转到预约页面

4、在预约页面录入体检人信息，包括手机号，点击发送验证码

5、在预约页面录入收到的手机短信验证码，点击提交预约，完成体检预约

体检预约

页面调整

在预约页面（/pages/orderInfo.html）进行调整

展示预约的套餐信息

第一步：从请求路径中获取当前套餐的id

<script>
  var id = getUrlParam("id");//套餐id
</script>

第二步：定义模型数据setmeal，用于套餐数据展示

var vue = new Vue({
  el:'#app',
  data:{
    setmeal:{},//套餐信息
    orderInfo:{
      setmealId:id,
      sex:'1'
    }//预约信息
  }
});

<div class="card">
  <div class="">
    <img :src="'http://pqjroc654.bkt.clouddn.com/'+setmeal.img" width="100%" height="100%" />
  </div>
  <div class="project-text">
    <h4 class="tit">{{setmeal.name}}</h4>
    <p class="subtit">{{setmeal.remark}}</p>
    <p class="keywords">
        <span>{{setmeal.sex == '0' ? '性别不限' : setmeal.sex == '1' ? '男':'女'}}</span>
        <span>{{setmeal.age}}</span>
    </p>
  </div>
  <div class="project-know">
    <a href="orderNotice.html" class="link-page">
      <i class="icon-ask-circle"><span class="path1"></span><span class="path2"></span></i>
      <span class="word">预约须知</span>
      <span class="arrow"><i class="icon-rit-arrow"></i></span>
    </a>
  </div>
</div>

第三步：在VUE的钩子函数中发送ajax请求，根据id查询套餐信息

mounted(){
  axios.post("/setmeal/findById.do?id=" + id).then((response) => {
    this.setmeal = response.data.data;
  });
}

手机号校验

第一步：在页面导入的healthmobile.js文件中已经定义了校验手机号的方法

/**
 * 手机号校验
 1--以1为开头；
 2--第二位可为3,4,5,7,8,中的任意一位；
 3--最后以0-9的9个整数结尾。
 */
function checkTelephone(telephone) {
    var reg=/^[1][3,4,5,7,8][0-9]{9}$/;
    if (!reg.test(telephone)) {
        return false;
    } else {
        return true;
    }
}

第二步：为发送验证码按钮绑定事件sendValidateCode

<div class="input-row">
  <label>手机号</label>
  <input v-model="orderInfo.telephone" 
         type="text" class="input-clear" placeholder="请输入手机号">
  <input style="font-size: x-small;" 
         id="validateCodeButton" @click="sendValidateCode()" type="button" value="发送验证码">
</div>

//发送验证码
sendValidateCode(){
  //获取用户输入的手机号
  var telephone = this.orderInfo.telephone;
  //校验手机号输入是否正确
  if (!checkTelephone(telephone)) {
    this.$message.error('请输入正确的手机号');
    return false;
  }
}

30秒倒计时效果

前面在sendValidateCode方法中进行了手机号校验，如果校验通过，需要显示30秒倒计时效果

//发送验证码
sendValidateCode(){
  //获取用户输入的手机号
  var telephone = this.orderInfo.telephone;
  //校验手机号输入是否正确
  if (!checkTelephone(telephone)) {
    this.$message.error('请输入正确的手机号');
    return false;
  }
  validateCodeButton = $("#validateCodeButton")[0];
  clock = window.setInterval(doLoop, 1000); //一秒执行一次
}

其中，validateCodeButton和clock是在healthmobile.js文件中定义的变量，doLoop是在healthmobile.js文件中定义的方法

var clock = '';//定时器对象，用于页面30秒倒计时效果
var nums = 30;
var validateCodeButton;
//基于定时器实现30秒倒计时效果
function doLoop() {
    validateCodeButton.disabled = true;//将按钮置为不可点击
    nums--;
    if (nums > 0) {
        validateCodeButton.value = nums + '秒后重新获取';
    } else {
        clearInterval(clock); //清除js定时器
        validateCodeButton.disabled = false;
        validateCodeButton.value = '重新获取验证码';
        nums = 30; //重置时间
    }
}

发送ajax请求

在按钮上显示30秒倒计时效果的同时，需要发送ajax请求，在后台给用户发送手机验证码

//发送验证码
sendValidateCode(){
  //获取用户输入的手机号
  var telephone = this.orderInfo.telephone;
  //校验手机号输入是否正确
  if (!checkTelephone(telephone)) {
    this.$message.error('请输入正确的手机号');
    return false;
  }
  validateCodeButton = $("#validateCodeButton")[0];
  clock = window.setInterval(doLoop, 1000); //一秒执行一次
  axios.post("/validateCode/send4Order.do?telephone=" + telephone).then((response) => {
    if(!response.data.flag){
      //验证码发送失败
      this.$message.error('验证码发送失败，请检查手机号输入是否正确');
    }
  });
}

创建ValidateCodeController，提供方法发送短信验证码，并将验证码保存到redis

package com.itheima.controller;
​
import com.aliyuncs.exceptions.ClientException;
import com.itheima.constant.MessageConstant;
import com.itheima.constant.RedisConstant;
import com.itheima.constant.RedisMessageConstant;
import com.itheima.entity.Result;
import com.itheima.utils.JedisUtils;
import com.itheima.utils.SMSUtils;
import com.itheima.utils.ValidateCodeUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import java.util.Random;
​
/**
 * 短信验证码
 */
@RestController
@RequestMapping("/validateCode")
public class ValidateCodeController {
    @Autowired
    private JedisPool jedisPool;
  
    //体检预约时发送手机验证码
    @RequestMapping("/send4Order")
    public Result send4Order(String telephone){
        Integer code = ValidateCodeUtils.generateValidateCode(4);//生成4位数字验证码
        try {
            //发送短信
            SMSUtils.sendShortMessage(SMSUtils.VALIDATE_CODE,telephone,code.toString());
        } catch (ClientException e) {
            e.printStackTrace();
            //验证码发送失败
            return new Result(false, MessageConstant.SEND_VALIDATECODE_FAIL);
        }
        System.out.println("发送的手机验证码为：" + code);
        //将生成的验证码缓存到redis
        jedisPool.getResource().setex(
          telephone + RedisMessageConstant.SENDTYPE_ORDER,5 * 60,code.toString());
        //验证码发送成功
        return new Result(true,MessageConstant.SEND_VALIDATECODE_SUCCESS);
    }
}

页面中使用DatePicker控件来展示日历。根据需求，最多可以提前一个月进行体检预约，所以日历控件只展示未来一个月的日期

<div class="date">
  <label>体检日期</label>
  <i class="icon-date" class="picktime"></i>
  <input v-model="orderInfo.orderDate" type="text" class="picktime" readonly>
</div>

<script>
  //日期控件
  var calendar = new datePicker();
  calendar.init({
    'trigger': '.picktime',/*按钮选择器，用于触发弹出插件*/
    'type': 'date',/*模式：date日期；datetime日期时间；time时间；ym年月；*/
    'minDate': getSpecifiedDate(new Date(),1),/*最小日期*/
    'maxDate': getSpecifiedDate(new Date(),30),/*最大日期*/
    'onSubmit': function() { /*确认时触发事件*/},
    'onClose': function() { /*取消时触发事件*/ }
  });
</script>

其中getSpecifiedDate方法定义在healthmobile.js文件中

//获得指定日期后指定天数的日期
function getSpecifiedDate(date,days) {
    date.setDate(date.getDate() + days);//获取指定天之后的日期
    var year = date.getFullYear();
    var month = date.getMonth() + 1;
    var day = date.getDate();
    return (year + "-" + month + "-" + day);
}

提交预约请求

为提交预约按钮绑定事件

<div class="box-button">
  <button @click="submitOrder()" type="button" class="btn order-btn">提交预约</button>
</div>

//提交预约
submitOrder(){
  //校验身份证号格式
  if(!checkIdCard(this.orderInfo.idCard)){
    this.$message.error('身份证号码输入错误，请重新输入');
    return ;
  }
  axios.post("/order/submit.do",this.orderInfo).then((response) => {
    if(response.data.flag){
      //预约成功，跳转到预约成功页面
      window.location.href="orderSuccess.html?orderId=" + response.data.data;
    }else{
      //预约失败，提示预约失败信息
      this.$message.error(response.data.message);
    }
  });
}

其中checkIdCard方法是在healthmobile.js文件中定义的

/**
 * 身份证号码校验
 * 身份证号码为15位或者18位，15位时全为数字，18位前17位为数字，最后一位是校验位，可能为数字或字符X
 */
function checkIdCard(idCard){
    var reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/;
    if(reg.test(idCard)){
        return true;
    }else{
        return false;
    }
}

后台代码

Controller

在health_mobile工程中创建OrderController并提供submitOrder方法

package com.itheima.controller;
​
import com.alibaba.dubbo.config.annotation.Reference;
import com.aliyuncs.exceptions.ClientException;
import com.itheima.constant.MessageConstant;
import com.itheima.constant.RedisConstant;
import com.itheima.constant.RedisMessageConstant;
import com.itheima.entity.Result;
import com.itheima.pojo.Member;
import com.itheima.pojo.Order;
import com.itheima.pojo.Setmeal;
import com.itheima.service.OrderService;
import com.itheima.utils.JedisUtils;
import com.itheima.utils.SMSUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import redis.clients.jedis.JedisPool;
import java.util.HashMap;
import java.util.Map;
​
/**
 * 体检预约
 */
@RestController
@RequestMapping("/order")
public class OrderController {
    @Reference
    private OrderService orderService;
    @Autowired
    private JedisPool jedisPool;
​
    /**
     * 体检预约
     * @param map
     * @return
     */
    @RequestMapping("/submit")
    public Result submitOrder(@RequestBody Map map){
        String telephone = (String) map.get("telephone");
        //从Redis中获取缓存的验证码，key为手机号+RedisConstant.SENDTYPE_ORDER
        String codeInRedis = jedisPool.getResource().get(
          telephone + RedisMessageConstant.SENDTYPE_ORDER);
        String validateCode = (String) map.get("validateCode");
        //校验手机验证码
        if(codeInRedis == null || !codeInRedis.equals(validateCode)){
            return new Result(false, MessageConstant.VALIDATECODE_ERROR);
        }
        Result result =null;
        //调用体检预约服务
        try{
            map.put("orderType", Order.ORDERTYPE_WEIXIN);
            result = orderService.order(map);
        }catch (Exception e){
            e.printStackTrace();
            //预约失败
            return result;
        }
        if(result.isFlag()){
            //预约成功，发送短信通知
            String orderDate = (String) map.get("orderDate");
            try {
                SMSUtils.sendShortMessage(SMSUtils.ORDER_NOTICE,telephone,orderDate);
            } catch (ClientException e) {
                e.printStackTrace();
            }
        }
        return result;
    }
}

服务接口

在health_interface工程中创建体检预约服务接口OrderService并提供预约方法

package com.itheima.service;
​
import com.itheima.entity.Result;
import java.util.Map;
/**
 * 体检预约服务接口
 */
public interface OrderService {
    //体检预约
    public Result order(Map map) throws Exception;
}

服务实现类

在health_service_provider工程中创建体检预约服务实现类OrderServiceImpl并实现体检预约方法。

体检预约方法处理逻辑比较复杂，需要进行如下业务处理：

1、检查用户所选择的预约日期是否已经提前进行了预约设置，如果没有设置则无法进行预约

2、检查用户所选择的预约日期是否已经约满，如果已经约满则无法预约

3、检查用户是否重复预约（同一个用户在同一天预约了同一个套餐），如果是重复预约则无法完成再次预约

4、检查当前用户是否为会员，如果是会员则直接完成预约，如果不是会员则自动完成注册并进行预约

5、预约成功，更新当日的已预约人数

实现代码如下：

package com.itheima.service;
​
import com.alibaba.dubbo.config.annotation.Service;
import com.itheima.constant.MessageConstant;
import com.itheima.dao.MemberDao;

        //检查当前日期是否进行了预约设置
        String orderDate = (String) map.get("orderDate");
        Date date = DateUtils.parseString2Date(orderDate);
        OrderSetting orderSetting = orderSettingDao.findByOrderDate(date);
        if(orderSetting == null){
            return new Result(false, MessageConstant.SELECTED_DATE_CANNOT_ORDER);
        }
      
        //检查预约日期是否预约已满
        int number = orderSetting.getNumber();//可预约人数
        int reservations = orderSetting.getReservations();//已预约人数
        if(reservations >= number){
            //预约已满，不能预约
            return new Result(false,MessageConstant.ORDER_FULL);
        }
      
        //检查当前用户是否为会员，根据手机号判断
        String telephone = (String) map.get("telephone");
        Member member = memberDao.findByTelephone(telephone);
        //防止重复预约
        if(member != null){
            Integer memberId = member.getId();
            int setmealId = Integer.parseInt((String) map.get("setmealId"));
            Order order = new Order(memberId,date,null,null,setmealId);
            List<Order> list = orderDao.findByCondition(order);
            if(list != null && list.size() > 0){
                //已经完成了预约，不能重复预约
                return new Result(false,MessageConstant.HAS_ORDERED);
            }
        }
        
        //可以预约，设置预约人数加一
        orderSetting.setReservations(orderSetting.getReservations()+1);
        orderSettingDao.editReservationsByOrderDate(orderSetting);
