# 课程安排
- 了解快递员取派件任务需求
- 递员取派件任务相关功能开发
- 调度中心任务调度
- 整体业务功能测试
# 1、背景说明
通过前面的学习,可以通过作业范围来确定网点或快递员,下面要做的事情就是需要为快递员生成取派件任务,这样快递员才能够进行相关的取件或派件作业。

具体需求参见《快递员端产品》文档。
# 3、实现分析
## 3.1、表结构
对于快递员的取件和派件动作,除了类型不同外其他的属性基本都是一样的,所以我们可以将存储在一张表中。
取派件任务存储在sl_work数据库中。
```sql
CREATE TABLE `sl_pickup_dispatch_task` (
`id` bigint NOT NULL COMMENT 'id',
`order_id` bigint NOT NULL COMMENT '关联订单id',
`task_type` tinyint DEFAULT NULL COMMENT '任务类型1为取件任务2为派件任务',
`status` int DEFAULT NULL COMMENT '任务状态1为新任务、2为已完成、3为已取消',
`sign_status` int DEFAULT '0' COMMENT '签收状态(0为未签收, 1为已签收2为拒收)',
`sign_recipient` tinyint DEFAULT '0' COMMENT '签收人1本人2代收',
`agency_id` bigint DEFAULT NULL COMMENT '网点ID',
`courier_id` bigint DEFAULT NULL COMMENT '快递员ID',
`estimated_start_time` datetime DEFAULT NULL COMMENT '预计取/派件开始时间',
`actual_start_time` datetime DEFAULT NULL COMMENT '实际开始时间',
`estimated_end_time` datetime DEFAULT NULL COMMENT '预计完成时间',
`actual_end_time` datetime DEFAULT NULL COMMENT '实际完成时间',
`cancel_time` datetime DEFAULT NULL COMMENT '取消时间',
`cancel_reason` int DEFAULT NULL COMMENT '取消原因',
`cancel_reason_description` varchar(100) CHARACTER SET armscii8 COLLATE armscii8_general_ci DEFAULT NULL COMMENT '取消原因具体描述',
`assigned_status` int NOT NULL COMMENT '任务分配状态(1未分配2已分配3待人工分配)',
`mark` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '备注',
`created` datetime DEFAULT NULL COMMENT '创建时间',
`updated` datetime DEFAULT NULL COMMENT '更新时间',
`is_deleted` int DEFAULT '0' COMMENT '删除0-否1-是',
PRIMARY KEY (`id`) USING BTREE,
KEY `order_id` (`order_id`) USING BTREE,
KEY `created` (`created`) USING BTREE,
KEY `task_type` (`task_type`) USING BTREE,
KEY `courier_id` (`courier_id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci ROW_FORMAT=DYNAMIC COMMENT='取件、派件任务信息表';
```
## 3.2、业务流程
### 3.2.1、取件任务流程
用户在下单后订单微服务会发消息出来消息会在dispatch微服务中进行调度计算最终会向work微服务发送消息用于生成快递员的取件任务。

派件任务会在两个场景下生成:
- 场景一,司机入库时,运单流转到最后一个节点,需要快递员派件
- 场景二,发件人与收件人的服务网点是同一个网点时,无需转运,直接生成派件任务
场景一:

针对于取派件任务进行相应的数据管理,下面我们将逐一进行实现。
## 4.1、新增取派件任务
新增取派件任务不对外开放所以在Controller中是没有方法定义的只是在消息处理中进行调用生成任务。
### 4.1.1、定义方法
```java
/**
* 新增取派件任务
*
* @param taskPickupDispatch 取派件任务信息
* @return 取派件任务信息
*/
PickupDispatchTaskEntity saveTaskPickupDispatch(PickupDispatchTaskEntity taskPickupDispatch);
```
### 4.1.2、实现方法
```java
@Override
public PickupDispatchTaskEntity saveTaskPickupDispatch(PickupDispatchTaskEntity taskPickupDispatch) {
// 设置任务状态为新任务
taskPickupDispatch.setStatus(PickupDispatchTaskStatus.NEW);
boolean result = super.save(taskPickupDispatch);
if (result) {
//TODO 同步快递员任务到es
//TODO 生成运单跟踪消息和快递员端取件/派件消息通知
return taskPickupDispatch;
}
throw new SLException(WorkExceptionEnum.PICKUP_DISPATCH_TASK_SAVE_ERROR);
}
```
## 4.2、分页查询取派件任务
### 4.2.1、Controller
```java
@PostMapping("page")
@ApiOperation(value = "分页查询", notes = "获取取派件任务分页数据")
public PageResponse<PickupDispatchTaskDTO> findByPage(@RequestBody PickupDispatchTaskPageQueryDTO dto) {
return this.pickupDispatchTaskService.findByPage(dto);
}
```
### 4.2.2、Service
```java
/**
* 分页查询取派件任务
*
* @param dto 查询条件
* @return 分页结果
*/
PageResponse<PickupDispatchTaskDTO> findByPage(PickupDispatchTaskPageQueryDTO dto);
```
### 4.2.3、ServiceImpl
```java
/**
* 分页查询取派件任务
*
* @param dto 查询条件
* @return 分页结果
*/
@Override
public PageResponse<PickupDispatchTaskDTO> findByPage(PickupDispatchTaskPageQueryDTO dto) {
//1.构造条件
Page<PickupDispatchTaskEntity> iPage = new Page<>(dto.getPage(), dto.getPageSize());
LambdaQueryWrapper<PickupDispatchTaskEntity> queryWrapper = Wrappers.<PickupDispatchTaskEntity>lambdaQuery()
.like(ObjectUtil.isNotEmpty(dto.getId()), PickupDispatchTaskEntity::getId, dto.getId())
.like(ObjectUtil.isNotEmpty(dto.getOrderId()), PickupDispatchTaskEntity::getOrderId, dto.getOrderId())
.eq(ObjectUtil.isNotEmpty(dto.getAgencyId()), PickupDispatchTaskEntity::getAgencyId, dto.getAgencyId())
.eq(ObjectUtil.isNotEmpty(dto.getCourierId()), PickupDispatchTaskEntity::getCourierId, dto.getCourierId())
.eq(ObjectUtil.isNotEmpty(dto.getTaskType()), PickupDispatchTaskEntity::getTaskType, dto.getTaskType())
.eq(ObjectUtil.isNotEmpty(dto.getStatus()), PickupDispatchTaskEntity::getStatus, dto.getStatus())
.eq(ObjectUtil.isNotEmpty(dto.getAssignedStatus()), PickupDispatchTaskEntity::getAssignedStatus, dto.getAssignedStatus())
.eq(ObjectUtil.isNotEmpty(dto.getSignStatus()), PickupDispatchTaskEntity::getSignStatus, dto.getSignStatus())
.eq(ObjectUtil.isNotEmpty(dto.getIsDeleted()), PickupDispatchTaskEntity::getIsDeleted, dto.getIsDeleted())
.between(ObjectUtil.isNotEmpty(dto.getMinEstimatedEndTime()), PickupDispatchTaskEntity::getEstimatedEndTime, dto.getMinEstimatedEndTime(), dto.getMaxEstimatedEndTime())
.between(ObjectUtil.isNotEmpty(dto.getMinActualEndTime()), PickupDispatchTaskEntity::getActualEndTime, dto.getMinActualEndTime(), dto.getMaxActualEndTime())
.orderByDesc(PickupDispatchTaskEntity::getUpdated);
//2.分页查询
Page<PickupDispatchTaskEntity> result = super.page(iPage, queryWrapper);
//3.实体类转为dto
return PageResponse.of(result, PickupDispatchTaskDTO.class);
}
```
## 4.3、按照时间查询任务数
### 4.3.1、Controller
```java
@GetMapping("count")
@ApiOperation(value = "任务数量查询", notes = "按照当日快递员id列表查询每个快递员的取派件任务数")
@ApiImplicitParams({
@ApiImplicitParam(name = "courierIds", value = "订单id列表", required = true),
@ApiImplicitParam(name = "taskType", value = "任务类型", required = true),
@ApiImplicitParam(name = "date", value = "日期格式yyyy-MM-dd 或 yyyyMMdd", required = true)
})
public List<CourierTaskCountDTO> findCountByCourierIds(@RequestParam("courierIds") List<Long> courierIds,
@RequestParam("taskType") PickupDispatchTaskType taskType,
@RequestParam("date") String date) {
return this.pickupDispatchTaskService.findCountByCourierIds(courierIds, taskType, date);
}
```
### 4.3.2、Service
```java
/**
* 按照当日快递员id列表查询每个快递员的取派件任务数
*
* @param courierIds 快递员id列表
* @param pickupDispatchTaskType 任务类型
* @param date 日期格式yyyy-MM-dd 或 yyyyMMdd
* @return 任务数
*/
List<CourierTaskCountDTO> findCountByCourierIds(List<Long> courierIds, PickupDispatchTaskType pickupDispatchTaskType, String date);
```
### 4.2.3、ServiceImpl
```java
@Override
public List<CourierTaskCountDTO> findCountByCourierIds(List<Long> courierIds, PickupDispatchTaskType pickupDispatchTaskType, String date) {
//计算一天的时间的边界
DateTime dateTime = DateUtil.parse(date);
LocalDateTime startDateTime = DateUtil.beginOfDay(dateTime).toLocalDateTime();
LocalDateTime endDateTime = DateUtil.endOfDay(dateTime).toLocalDateTime();
return this.taskPickupDispatchMapper
.findCountByCourierIds(courierIds, pickupDispatchTaskType.getCode(), startDateTime, endDateTime);
}
```
### 4.2.4、定义SQL
此方法的实现调用自定义Mapper中的SQL实现。
```xml
<select id="findCountByCourierIds" resultType="com.sl.ms.work.domain.dto.CourierTaskCountDTO">
SELECT
COUNT(1) `count`,
courier_id
FROM sl_pickup_dispatch_task t
WHERE
t.courier_id IN <foreach collection="courierIds" item="courierId" open="(" close=")" separator=",">#{courierId}</foreach>
AND t.created BETWEEN #{startDateTime} AND #{endDateTime}
AND t.task_type = #{type}
GROUP BY courier_id
</select>
```
## 4.4、根据订单查询任务
根据订单id查询取派件任务。
### 4.4.1、Controller
```java
@GetMapping("/orderId/{orderId}/{taskType}")
@ApiOperation(value = "订单id查询", notes = "根据订单id获取取派件任务信息")
@ApiImplicitParams({
@ApiImplicitParam(name = "orderId", value = "订单id"),
@ApiImplicitParam(name = "taskType", value = "任务类型")
})
public List<PickupDispatchTaskDTO> findByOrderId(@PathVariable("orderId") Long orderId,
@PathVariable("taskType") PickupDispatchTaskType taskType) {
List<PickupDispatchTaskEntity> entities = pickupDispatchTaskService.findByOrderId(orderId, taskType);
return BeanUtil.copyToList(entities, PickupDispatchTaskDTO.class);
}
```
### 4.4.2、Service
```java
/**
* 根据订单id查询取派件任务
*
* @param orderId 订单id
* @param taskType 任务类型
* @return 任务
*/
List<PickupDispatchTaskEntity> findByOrderId(Long orderId, PickupDispatchTaskType taskType);
```
### 4.4.3、ServiceImpl
```java
@Override
public List<PickupDispatchTaskEntity> findByOrderId(Long orderId, PickupDispatchTaskType taskType) {
LambdaQueryWrapper<PickupDispatchTaskEntity> wrapper = Wrappers.<PickupDispatchTaskEntity>lambdaQuery()
.eq(PickupDispatchTaskEntity::getOrderId, orderId)
.eq(PickupDispatchTaskEntity::getTaskType, taskType)
.orderByAsc(PickupDispatchTaskEntity::getCreated);
return this.list(wrapper);
}
```
## 4.5、id批量删除
根据id批量删除取派件任务信息逻辑删除
### 4.5.1、Controller
```java
@DeleteMapping("ids")
@ApiOperation(value = "id批量删除", notes = "根据id批量删除取派件任务信息逻辑删除")
@ApiImplicitParams({
@ApiImplicitParam(name = "ids", value = "任务id列表")
})

```
## 4.6、改派快递员
场景本来属于A快递员的取件任务由于某种原因A快递员不能执行此时A快递员可以改派给其他快递员会用到此接口。
另外,派件不支持直接改派,需要客服在后台操作。
### 4.6.1、Controller
```java
@PutMapping("courier")
@ApiOperation(value = "改派快递员", notes = "改派快递员")
@ApiImplicitParams({
@ApiImplicitParam(name = "id", value = "任务id", required = true),
@ApiImplicitParam(name = "originalCourierId", value = "原快递员id", required = true),
@ApiImplicitParam(name = "targetCourierId", value = "目标快递员id", required = true),
})
public Boolean updateCourierId(@RequestParam("id") Long id,
@RequestParam("originalCourierId") Long originalCourierId,
@RequestParam("targetCourierId") Long targetCourierId) {
return this.pickupDispatchTaskService.updateCourierId(id, originalCourierId, targetCourierId);
}
```
### 4.6.2、Service
```java
/**
* 改派快递员
*
* @param ids 任务id列表
* @param originalCourierId 原快递员id
* @param targetCourierId 目标快递员id
* @return 是否成功
*/
Boolean updateCourierId(List<Long> ids, Long originalCourierId, Long targetCourierId);
```
### 4.6.3、ServiceImpl
```java
@Override
public Boolean updateCourierId(List<Long> ids, Long originalCourierId, Long targetCourierId) {
if (ObjectUtil.hasEmpty(ids, targetCourierId, originalCourierId)) {
throw new SLException(WorkExceptionEnum.UPDATE_COURIER_PARAM_ERROR);
}
if (ObjectUtil.equal(originalCourierId, targetCourierId)) {
throw new SLException(WorkExceptionEnum.UPDATE_COURIER_EQUAL_PARAM_ERROR);
}
List<PickupDispatchTaskEntity> entities = super.listByIds(ids);
if (CollUtil.isEmpty(entities)) {
throw new SLException(WorkExceptionEnum.PICKUP_DISPATCH_TASK_NOT_FOUND);
}
entities.forEach(entity -> {
//校验原快递id是否正确本来无快递员id的情况除外
if (ObjectUtil.isNotEmpty(entity.getCourierId())
&& ObjectUtil.notEqual(entity.getCourierId(), originalCourierId)) {
throw new SLException(WorkExceptionEnum.UPDATE_COURIER_ID_PARAM_ERROR);
}
//更改快递员id
entity.setCourierId(targetCourierId);
// 标识已分配状态
entity.setAssignedStatus(PickupDispatchTaskAssignedStatus.DISTRIBUTED);
});
//批量更新
List<Long> taskIds = entities.stream().map(PickupDispatchTaskEntity::getId).collect(Collectors.toList());
LambdaUpdateWrapper<PickupDispatchTaskEntity> updateWrapper = Wrappers.<PickupDispatchTaskEntity>lambdaUpdate()
.in(PickupDispatchTaskEntity::getId, taskIds)
.set(PickupDispatchTaskEntity::getCourierId, targetCourierId)
.set(PickupDispatchTaskEntity::getAssignedStatus, PickupDispatchTaskAssignedStatus.DISTRIBUTED);
boolean result = super.update(updateWrapper);
if (result) {
//TODO 发送消息同步更新快递员任务ES
}
return result;
}
```
## 4.7、更新取派件状态
实现更新取派件任务状态功能时,需要考虑如下几点:
- 更新的状态不能为【新任务】状态
- 更新状态为【已完成】并且任务类型为派件任务时,必须设置签收状态和签收人
- 更新状态为【已取消】,是取件任务的操作,根据不同的原因有不同的处理逻辑
- 【因个人无法取件,退回到网点】,需要发送消息重新生成取件任务
- 【用户取消投递】,需要取消订单
- 其他原因(用户恶意下单、禁用品、重复下单等),需要关闭订单
快递员取消时选择的原因:

## 4.11、测试
可以通过编写单元测试或swagger接口进程测试。
```java
package com.sl.ms.work.service;
import com.sl.ms.work.domain.enums.pickupDispatchtask.PickupDispatchTaskAssignedStatus;
import com.sl.ms.work.domain.enums.pickupDispatchtask.PickupDispatchTaskSignStatus;
import com.sl.ms.work.domain.enums.pickupDispatchtask.PickupDispatchTaskType;
import com.sl.ms.work.entity.PickupDispatchTaskEntity;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import javax.annotation.Resource;
@SpringBootTest
class PickupDispatchTaskServiceTest {
@Resource
private PickupDispatchTaskService pickupDispatchTaskService;
/**
* 测试新增取件任务
*/
@Test
void saveTaskPickupDispatch() {
PickupDispatchTaskEntity pickupDispatchTaskEntity = new PickupDispatchTaskEntity();
pickupDispatchTaskEntity.setCourierId(1019618890088508577L);
pickupDispatchTaskEntity.setOrderId(1564170062718373889L);
pickupDispatchTaskEntity.setAgencyId(1015716681416180257L);
pickupDispatchTaskEntity.setTaskType(PickupDispatchTaskType.PICKUP);
pickupDispatchTaskEntity.setMark("带包装");
pickupDispatchTaskEntity.setSignStatus(PickupDispatchTaskSignStatus.NOT_SIGNED);
pickupDispatchTaskEntity.setAssignedStatus(PickupDispatchTaskAssignedStatus.DISTRIBUTED);
PickupDispatchTaskEntity pickupDispatchTask = this.pickupDispatchTaskService.saveTaskPickupDispatch(pickupDispatchTaskEntity);
System.out.println(pickupDispatchTask);
}
}
```
基于swagger的测试

# 5、调度中心
在调度中心中对于生成取派件任务的消息进行处理,消息内容类似这样:
```json
{
"orderId": 123,
"agencyId": 8001,
"taskType": 1,
"mark": "带包装",
"longitude": 116.111,
"latitude": 39.00,
"created": 1654224658728,
"estimatedStartTime": 1654224658728
}
```
实现的关键点:
- 如果只查询到一个快递员,直接分配即可
- 如果是多个快递员,需要查询这些快递员当日的任务数,按照最少的进行分配,这样可以做到相对均衡
- 如果没有快递员设置快递员id为空可以在后台系统中人为的进行调配快递员
- 对于取件任务而言,需要考虑用户选择的【期望上门时间】
- 与当前时间相比大于2小时发送延时消息否则发送实时消息

## 5.2、测试
对于`OrderMQListener`的测试,需要启动必要的服务,因为需要查询快递员(不查询也可以,就是无快递员的逻辑),此时就需要确保有快递员数据(确保在服务范围内或有所在机构的快递员),准备完成后,先进行单元测试,后面再进行整合测试。
```shell
docker start sl-express-gateway
docker start sl-express-ms-base-service
docker start sl-express-ms-courier-service
docker start sl-express-ms-web-manager
docker start sl-express-ms-service-scope-service
```
启动之后,可以查看快递员的排班情况:

编写单元测试:
```java
package com.sl.ms.dispatch.mq;

# 6、生成任务
在work微服务中可以接收到来自调度中心的消息接下来我们需要编写消费消息的逻辑生成快递员的取派件任务。
## 6.1、消费消息
```java
/**
* 生成快递员取派件任务
*
* @param msg 消息
*/
@RabbitListener(bindings = @QueueBinding(
value = @Queue(name = Constants.MQ.Queues.WORK_PICKUP_DISPATCH_TASK_CREATE),
exchange = @Exchange(name = Constants.MQ.Exchanges.PICKUP_DISPATCH_TASK_DELAYED, type = ExchangeTypes.TOPIC, delayed = Constants.MQ.DELAYED),
key = Constants.MQ.RoutingKeys.PICKUP_DISPATCH_TASK_CREATE
))
public void listenCourierTaskMsg(String msg) {
//{"taskType":1,"orderId":225125208064,"created":1654767899885,"courierId":1001,"agencyId":8001,"estimatedStartTime":1654224658728,"mark":"带包装"}
log.info("接收到快递员任务的消息 >>> msg = {}", msg);
//解析消息
CourierTaskMsg courierTaskMsg = JSONUtil.toBean(msg, CourierTaskMsg.class);
//幂等性处理:判断订单对应的取派件任务是否存在,判断条件:订单号+任务状态
List<PickupDispatchTaskEntity> list = this.pickupDispatchTaskService.findByOrderId(courierTaskMsg.getOrderId(), PickupDispatchTaskType.codeOf(courierTaskMsg.getTaskType()));
for (PickupDispatchTaskEntity pickupDispatchTaskEntity : list) {
if (pickupDispatchTaskEntity.getStatus() == PickupDispatchTaskStatus.NEW) {
//消息重复消费
return;
}
}
// 订单不存在 不进行调度
OrderDTO orderDTO = orderFeign.findById(courierTaskMsg.getOrderId());
if (ObjectUtil.isEmpty(orderDTO)) {
return;
}
// 如果已经取消或者删除 则不进行调度
if (orderDTO.getStatus().equals(OrderStatus.CANCELLED.getCode()) || orderDTO.getStatus().equals(OrderStatus.DEL.getCode())) {
return;
}
PickupDispatchTaskEntity pickupDispatchTask = BeanUtil.toBean(courierTaskMsg, PickupDispatchTaskEntity.class);
//任务类型
pickupDispatchTask.setTaskType(PickupDispatchTaskType.codeOf(courierTaskMsg.getTaskType()));
//预计开始时间,结束时间向前推一小时
LocalDateTime estimatedStartTime = LocalDateTimeUtil.offset(pickupDispatchTask.getEstimatedEndTime(), -1, ChronoUnit.HOURS);
pickupDispatchTask.setEstimatedStartTime(estimatedStartTime);
// 默认未签收状态
pickupDispatchTask.setSignStatus(PickupDispatchTaskSignStatus.NOT_SIGNED);
//分配状态
if (ObjectUtil.isNotEmpty(pickupDispatchTask.getCourierId())) {
pickupDispatchTask.setAssignedStatus(PickupDispatchTaskAssignedStatus.DISTRIBUTED);
} else {
pickupDispatchTask.setAssignedStatus(PickupDispatchTaskAssignedStatus.MANUAL_DISTRIBUTED);
}
PickupDispatchTaskEntity result = this.pickupDispatchTaskService.saveTaskPickupDispatch(pickupDispatchTask);
if (result == null) {
//保存任务失败
throw new SLException(StrUtil.format("快递员任务保存失败 >>> msg = {}", msg));
}
}
```
## 6.2、测试
测试时需要启动oms服务
```shell
docker start sl-express-ms-oms-service
```
测试方法:通过`com.sl.ms.dispatch.mq.OrderMQListenerTest#listenOrderMsg()`的测试发出消息在work中消费消息生成取件任务。
测试结果:

# 7、整体测试
将相应的服务启动,基于四端进行测试。测试整个主流程,下单 → 取件任务 → 运输任务 → 转运 → 派件任务 → 签收。
# 8、练习
## 8.1、练习1
难度系数:★★☆☆☆
描述:阅读订单微服务中下单的业务逻辑代码。
## 8.2、练习2
难度系数:★★☆☆☆
描述:阅读快递员微服务中查询范围内快递员的代码。
# 9、面试连环问
:::info
面试官问:
- 用户下单后,是如何确认上门取件的快递员的?如果有多个快递员怎么处理?
- 系统分配给快递员的取件任务,快递员如果将任务取消后,该如何处理?
- 生成取件任务,为什么会用到延时队列?
- 生成取派件任务为什么不在work中直接生成而是发消息到调度中心再发消息到work中
