实现Model 检索、新增、编辑、删除、导出和部署功能。
Activiti 之Model 模型管理页面操作：Model 首页：
Model 检索：
Model 新增：
Model 编辑：
简单设计转正流程，记得点击保存按钮。
Model 导出：
Model 删除：
5001 流程模型已经被删除。
Model 部署：
功能说明：依据流程模型定义发起一次流程实例，由于该功能涉及用户和用户组设置、表单设计。这里仅仅实现在控制台后端输出流程实例Id。
选择模型定义，点击部署：
请教流程实例Id输出：
SpringBoot 之Activiti Model 模型管理后台SpringBoot程序入口排除Activiti自带SpringSecurity 安全框架校验

SpringBoot 引入前端开发框架LayUI
在layUI 开源网站中，下载LayUI。下载地址：Layui - 经典开源模块化前端 UI 框架
在本项目的resource/static文件夹中，引入layui 框架。
