11activiti - 入门demo（IDEA）

代码已上传至Github：https://github.com/ylw-github/Activiti-Demo.git

1.新建maven项目

点击next,输入GroupId和ArtifactId，点击next，定义项目名和项目地址，Finish之后项目就建好了。

2.添加依赖

3.绘制工作流

使用bpmn插件，在java的resource目录下，点击New，选择BpmnFile，创建bpmn文件

我们需要一个开始，一个结束，两个UserTask
我们需要修改两个UserTask的Name和Assignee,如图:

员工请假：

经理审批：

保存之后打开可能会出现乱码，解决办法参考：https://blog.csdn.net/vimonkey/article/details/72910153

4.代码

在recourse目录下写一个activiti的配置文件activiti.cfg.xml。

新建测试工具类ActivitiTest.java,运行创建工作流方法

运行成功：

打开数据库，发现已经自动生成表了

下面附上完整的代码：
