idea集成Activiti 拖拽生成bpmn文件过程

idea集成Activiti 拖拽生成bpmn文件过程是使用工作流的第一步，今天我们拿一个业务场景来举例，比如文件归档业务：文件查询、创建临时目录、文件解压（如果是压缩包才需要解压）、文件验证、文件归档、文件入库、同时写入缓存和记录日志；

1、idea安装插件

2、boot服务生成文件

此处activiti集成boot服务参考:[上一篇][Link 1]

3、点击文件右键鼠标

![fe27555af32242ec9a22bc79833a16a5.png][]

进入查看编辑页面

此时就可以开始拖拽流程图了。

4、右键开始

创建完成后可以配置参数

此时bpmn文件同时做出改变，可以看看

此后就配置各种事件和网关了。

5、右键创建任务

配置参数

![56703dfb1d794082af3e6e2bd0beaf7a.png][]

注意：

1）、Class 是指定一个业务类,比如：

com.nandao.bpm.CommonJavaDelegate

2）、Expression 使用表达式解析一个方法，比如 ：

${testServer.doWork()}

3）、Delegate Expression 使用委托表达式指定一个对象，此对象首个字母必须改为小写，否则报错：

4）、以上三个参数只能配置一个，否则可能报错

Unknown property used in expression: ${XXX}

6、自定义条件

![c1398851b9074c1697369af5024bce27.png][]

判断参数 isZip==false，就不执行解压，条件判断，如果是可以这样判断 isZip==true

另外 ：xsi:type 含义不知道,值为tFormalExpression;

一般前面可以添加一个排他网关，这样更安全，但是有需要注意的地方。

注意：排他网关只会选择一个为true的分支执行；如果有两个分支条件都为true，排他网关会选择id值较小的一条分支去执行；如果条件都不满足，流程就结束了(是异常结束) 。

7、并行网关

![34ee0a7cecd74875a4625f86b356d111.png][]

注意：并行网关不会解析条件。 即使顺序流中定义了条件，也会被忽略。

除了刚才说的两种网关，还有包含网关、事件网关，用到时可以查一下，基本思路是一致的。

8、工作流结束

9、最终流程图

也可以下载，保存到某个目录
