idea2020.1集成actibpm插件

由于项目需要使用到Activiti工作流框架，而idea2020.1没有直接下载的插件，需要手动安装，故记录下，以后方便安装使用。

1、下载安装插件

版本是2020.1.1

idea插件官网

选择本地安装

找到下载到的本地的jar，然后重启idea即可。

安装完之后

2、编写demo测试

2.1、创建springboot项目

2.2、引入依赖

2.3、创建流程文件

各个流程配置如下：

2.4、复制test.bpmn,并重命名（名字一定要以 bpmn20结尾）

生成png图片

将生成的图片导出到processes目录下

2.5、代码

测试类

2.6、测试

加载activiti.cfg.xml配置文件并部署流程

启动流程

根据角色查看任务

处理任务
