来源：互联网发布：网络应用软件编辑：程序博客网时间：2024/04/30 05:04

业务用例描述
核心工作流：
1、员工填写请假申请单，包括“请假原因”和“请假天数”，填写后进行提交；
2、部门主管对员工请假申请进行审批，同意员工请假；
3、人力资源主管对员工请假申请进行审批，同意员工请假；
4、系统发送邮件通知员工请假申请已获得批准；

5、用例结束；

工作流定义文件说明
依据本业务需求的工作流定义文件如下
定义中包括6个step

step1是员工请假申请的步骤，本步骤的action在执行时将回调业务方法类ApplyFunction，将申请单数据插入到数据库中，同时处理结果将根据请假申请天数dayCount进行判断，如果请假申请天数大于3天，将跳到step2让部门主管审批，如果不大于3天，将直接跳到step3让人力资源主管审批；

step2 是部门主管审批，如果审批同意（opinion!=2）将跳到step3再由人力资源主管审批，如果审批不同意（opinion==2）将跳到step5自动发“申请未批准”邮件通知步骤；

step3 是人力资源主管审批，如果审批同意（opinion!=2）将跳到step4自动发“申请批准”邮件通知步骤，如果审批不同意（opinion==2）将跳到step5自动发“申请未批准”邮件通知步骤；

step4和step5都是自动发送邮件通知步骤，执行完之后跳到空步骤step6结束该工作流实例。
