《项目开发团队分配管理软件》，nginx 面试题阿里
--------------------团队成员列表---------------------
TDI/ID ?姓名 ? ?年龄 ? ? ?工资 ? ? ? 职位 ? ? ?奖金 ? ? ? ?股票 ?
2/4 ? ? 刘强东 ? 24 ? ? ?7300.0 ? ?程序员 ?
3/2 ? ? 马化腾 ? 32 ? ? ?18000.0 ?架构师 ? 15000.0 ?2000 ?
4/6 ? ? 任志强 ? 22 ? ? ?6800.0 ? ?程序员 ?
5/12 ? 杨致远 ? 27 ? ? ?600.0 ? ? ?设计师 ? 4800.0
-----------------------------------------------------
TeamService 类的设计：
功能：关于开发团队成员的管理：添加、删除等（还需要自行实现）。
说明：
counter 为静态变量，用来为开发团队新增成员自动生成团队中的唯一 ID，即 memberId。（提示：应使用增 1 的方式）
MAX_MEMBER：表示开发团队最大成员数
team 数组：用来保存当前团队中的各成员对象 （也可以用一个新的集合）
total：记录团队成员的实际人数
TeamService 类的设计：
getTeam()方法：返回当前团队的所有对象
返回：包含所有成员对象的数组，数组大小与成员人数一致
addMember(e: Employee)方法：向团队中添加成员
参数：待添加成员的对象
异常：添加失败， TeamException 中包含了失败原因
removeMember(memberId: int)方法：从团队中删除成员
参数：待删除成员的 memberId
异常：找不到指定 memberId 的员工，删除失败
另外，可根据需要自行添加其他方法或重载构造器
TeamView 类的设计
说明：
listSvc 和 teamSvc 属性：供类中的方法使用
enterMainMenu ()方法：主界面显示及控制方法。
以下方法仅供 enterMainMenu()方法调用：
listAllEmployees ()方法：以表格形式列出公司所有成员
getTeam()方法：显示团队成员列表操作
addMember ()方法：实现添加成员操作
deleteMember ()方法：实现删除成员操作?
4.开发项目管理模块
在 domain 包中完成项目实体类 Project 的创建
在 service 包中完成项目操作类 ProjectService 的创建
其他还需要的方法属性可自行添加
IndexView 类的设计?
最后在 view 包中编写项目程序运行主界面类 IndexView
将前面 4 个模块的内容装在一起，并运行软件，操作基本功能，调试 bug，项目开发完成。
五、架构展开
======
如果没有参考代码的话，对于我们应该如何进行展开呢？
让我们来看看----系统功能结构：
很一目了然，我们能看出，我们需要做的就是创建四个模块，最后收成一个整体，让各个子体关联上，文本运行正常无 BUG 就完成了。
所以我建议的是，一个模块一个模块的做，然后做好一个用 main 方法测试通过，最后想办法凑一堆，让它跑！！！！
系统流程：
