乘客端不像司机端需要检验用户是否存在，如果不存在会直接进行注册，所以不再需要调用service-passenger-user服务

司机端

司机登录时序图

双Token时序图

利用JWT（Json Web Token）生成token

该流程主要在accessToken失效后，利用refreshToken生成新的Token

实现细节

用户登录

/**
     * 注册登录逻辑
     * @param passengerPhone
     * @return
     */
    public ResponseResult loginOrRegister(String passengerPhone){
        System.out.println("user service被调用，手机号：" + passengerPhone);

        //  根据手机号查询用户信息
        Map<String,Object> map = new HashMap<>();
        map.put("passenger_phone",passengerPhone);
        List<PassengerUser> passengerUsers = passengerUserMapper.selectByMap(map);
        System.out.println(passengerUsers.size() == 0 ? "无记录": passengerUsers.get(0).getPassengerPhone());

        //  判断用户信息是否存在
        if(passengerUsers.size() == 0){
            //  如果不存在，插入用户信息
            PassengerUser passengerUser = new PassengerUser();
            passengerUser.setPassengerName("张三");
            passengerUser.setPassengerGender((byte) 0);
            passengerUser.setPassengerPhone(passengerPhone);
            passengerUser.setState((byte) 0);

            LocalDateTime now = LocalDateTime.now();
            passengerUser.setGmtCreate(now);
            passengerUser.setGmtModified(now);

            passengerUserMapper.insert(passengerUser);
        }
    }

支付系统

调用支付宝接口活动图

实现细节

阿里支付SDK调用

aliPayConfig（配置类，用来作工厂初始化的配置）

package com.mashibing.servicepay.config;

import com.alipay.easysdk.factory.Factory;
import com.alipay.easysdk.kernel.Config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;


import javax.annotation.PostConstruct;

@Component
@ConfigurationProperties(prefix = "alipay")
@Data
public class AlipayConfig {

    private String appId;

    private String appPrivateKey;

    private String publicKey;

    private String notifyUrl;

    @PostConstruct
    public void init(){
        Config config = new Config();
        //  基础配置
        config.protocol = "https";
        config.gatewayHost = "openapi.alipaydev.com";
        config.signType = "RSA2";

        //  业务配置
        config.appId = this.appId;
        config.merchantPrivateKey = this.appPrivateKey;
        config.alipayPublicKey = this.publicKey;
        config.notifyUrl = this.notifyUrl;

        Factory.setOptions(config);
        System.out.println("支付宝配置初始化完成");
    }
}

支付服务

@GetMapping("/pay")
    public String pay(String subject,String outTradeNo,String totalAmount){
        //	设置响应信息
        AlipayTradePagePayResponse response;
        try {
            //	利用alipay的Factory生成支付窗口，进行支付即可
            response = Factory.Payment.Page().pay(subject,outTradeNo,totalAmount,"");
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException();
        }
        return response.getBody();
    }

支付响应

 @RequestMapping("/notify")
    public String notify(HttpServletRequest request) throws Exception {
        System.out.println("支付回调 notify");
        String tradeStatus = request.getParameter("trade_status");
       	//	判断支付是否成功了
        if (tradeStatus.trim().equals("TRADE_SUCCESS")){
            //	获得响应头的信息进行进一步判断
            Map<String,String> param = new HashMap<>();

            Map<String,String[]> parameterMap = request.getParameterMap();
            //	获取所有响应头的key
            for (String name: parameterMap.keySet()){
                param.put(name,request.getParameter(name));
            }
		   //	一键验证
            if (Factory.Payment.Common().verifyNotify(param)){
                System.out.println("通过支付宝的验证");
			   //	获得支付的订单号并同步更新到订单中
                String out_trade_no = param.get("out_trade_no");
                Long orderId = Long.parseLong(out_trade_no);
                alipayService.pay(orderId);
            }else {
                System.out.println("支付宝验证 不通过!");
            }
        }
        return "success";
    }

计价系统

计价规则传递扩展

问题：计价规则有更新，下单时不知道

办法：当检测到计价规则有变动的时候，提示用户重新计算预估价格。

预估价格时序图

实现细节

计价规则的添加（通过拼接cityCode以及vehicleTpye形成fareType）

public ResponseResult add(PriceRule priceRule) {
        //  拼接fare_type
        String cityCode = priceRule.getCityCode();
        String vehicleType = priceRule.getVehicleType();
        //  通过城市code以及车辆类型来拼接版本类型
        String fareType = cityCode + "$" + vehicleType;

        priceRule.setFareType(fareType);

        QueryWrapper queryWrapper = new QueryWrapper();
        queryWrapper.eq("city_code", cityCode);
        queryWrapper.eq("vehicle_type", vehicleType);
        queryWrapper.orderByDesc("fare_version");

        List<PriceRule> list = priceRuleMapper.selectList(queryWrapper);
        Integer fareVersion = 0;
        if (list.size() > 0) {
            return ResponseResult.fail(CommonStatusEnum.PRICE_RULE_EXISTS.getCode(), CommonStatusEnum.PRICE_RULE_EXISTS.getValue());
        }
        priceRule.setFareVersion(++fareVersion);
        priceRuleMapper.insert(priceRule);
        return ResponseResult.success();
    }

得到最新版本的计价规则（通过orderByDesc排序）

public ResponseResult<PriceRule> getNewestVersion(String fareType){
    QueryWrapper queryWrapper = new QueryWrapper();
    queryWrapper.eq("fare_type",fareType);
    queryWrapper.orderByDesc("fare_version");

    List<PriceRule> list = priceRuleMapper.selectList(queryWrapper);
    if (list.size() > 0){
        return ResponseResult.success(list.get(0));
    }else{
        return ResponseResult.fail(CommonStatusEnum.PRICE_RULE_EMPTY.getCode(),CommonStatusEnum.PRICE_RULE_EMPTY.getValue());
    }
}

订单系统

订单状态图

订单无效（0）

订单开始（1）

司机接单（2）

司机去接乘客（3）

司机到达乘客起点（4）

乘客上车，行程开始（5）

乘客到达指定地点（6）

司机发起收款（7）

乘客支付完成（8）

订单取消（9）

在状态5之前都可以进行取消，让订单进入取消状态

乘客下订单时序图

派单业务流程图

首先验证用户信息的合理性

对于业务情况进行检验，主要包括对当地是否开通业务？是否有计价规则？是否有司机？三个方面进行检验

同时开展三个逻辑：派单业务、定时任务、消息推送

派单业务主要分为实时订单和预约订单（无需查找）

实时订单通过对2km，4km，6km的反复搜索来搜索相关的司机

最后如果找到了司机就同时向乘客和司机推送消息

实现细节

定时任务处理（在一段时间内反复进行派单直到成功）

 //  定时任务的处理
        for (int i = 0; i < 6; i++) {
            //  派单
            int result = dispatchRealTimeOrder(order);
            if (result == 1){

派单逻辑

派单的整个逻辑

获得订单中所要求的经纬度，进行周围搜索车辆终端

找到能进行该订单的车辆id

根据车辆id找到司机，查询司机是否有正在进行的订单

查询车辆是否符合订单要求的车辆类型

通知司机、通知乘客

        ResponseEntity<String> result = restTemplate.getForEntity(url.toString(), String.class);

        return result.getBody();
    }

解析Json数据

利用JSONObject类获得Json数据，再利用get方法获得各个关键字的信息

 /**
     * 插入行政区数据
     * @param keywords
     * @return
     */
    public ResponseResult initDicDistrict(String keywords){

                String provinceName = provinceJsonObject.getString(AmapConfigConstant.NAME);
                String provinceParentAddressCode = countryCode;
                String provinceLevel = provinceJsonObject.getString(AmapConfigConstant.LEVEL);
                insertData(provinceCode,provinceName,provinceParentAddressCode,getLevel(provinceLevel));
                //  解析市县数据

                    String cityCode = cityJsonObject.getString(AmapConfigConstant.ADCODE);
                    String cityName = cityJsonObject.getString(AmapConfigConstant.NAME);
                    String cityParentAddressCode = provinceCode;
                    String cityLevel = cityJsonObject.getString(AmapConfigConstant.LEVEL);
                    if (cityLevel.equals("district")){
                        continue;

                    insertData(cityCode,cityName,cityParentAddressCode,getLevel(cityLevel));
                }
            }
        }

        return ResponseResult.success();
    }

SSE通知系统

实现细节

建立连接

public static Map<String,SseEmitter> sseEmitterMap = new HashMap<>();

    /**
     * 建立连接
     * @param userId
     * @param identity
     * @return
     */
    @GetMapping("/connect")
    public SseEmitter connect(@RequestParam Long userId,@RequestParam String identity){
        log.info("用户ID:" + userId + ",身份类型:" + identity) ;
	    //	通过将内容放到SseEmitter中作为连接成功与否的判断标准
        SseEmitter sseEmitter = new SseEmitter(0L);

        String sseMapKey = SsePrefixUtils.generatorSseKey(userId, identity);
        sseEmitterMap.put(sseMapKey,sseEmitter);
        return sseEmitter;
    }

发送消息

/**
     * 发送消息
     * @param userId    用户id
     * @param identity  身份类型
     * @param content   消息内容
     * @return
     */
    @GetMapping("/push")
    public String push(@RequestParam Long userId,@RequestParam String identity,@RequestParam String content){

        log.info("用户ID:" + userId + ",身份类型:" + identity) ;
        String sseMapKey = SsePrefixUtils.generatorSseKey(userId, identity);
        try {
            if (sseEmitterMap.containsKey(sseMapKey)){
                //	通过静态成员变量再次获得SseEmitter来发送消息
                sseEmitterMap.get(sseMapKey).send(content);
            }else {
                return "推送失败";
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "给用户:" + sseMapKey + "发送了消息:" + content;
    }

这边发送，html页面会有对应的事件响应器

source = new EventSource("http://localhost:9000/connect?userId=" + userId+"&identity="+identity);

    if (window.EventSource){
        console.log("此浏览器支持SSE");

        //  监听服务的推送的内容
        source.addEventListener("message",function (e) {
            content = e.data;
            console.log(content);
            sendMessageContent(content);
        });

    }else {
        console.log("此浏览器不支持");
    }

    function sendMessageContent(content) {
        document.getElementById("message").innerHTML += (content+'</br>');
    }

验证码系统

实现细节

生成验证码

这里就是用一个随机数来生成的验证码

 @GetMapping("/numberCode/{size}")
    public ResponseResult numberCode(@PathVariable("size") int size){
        System.out.println("size:" + size);
        //  生成验证码
        //  获取随机数,利用小数点往后移就可以了，就是相当于乘
        double mathRandom = (Math.random() * 9 + 1 ) * Math.pow(10,size-1);
        int resultInt = (int)mathRandom;
        System.out.println("generate src code:"+ resultInt);

        //  定义返回值
        NumberCodeResponse response = new NumberCodeResponse();
        response.setNumberCode(resultInt);

        return ResponseResult.success(response);
    }
