New BPMN file used by activiti workflow

Activiti Workflow use new bpmn file

One 、bpmn The file is introduced

Business process modeling and annotation （Business Process Model and Notation,BPMN) , The basic symbols that describe the process , Including how these elements are combined into a business flow chart （Business Process Diagram）

idea Draw the process , There are two files bpmn Document and png file , among bpmn File can also be called process definition file , It needs to follow BPMN language norm .png: It's just a simple picture , It doesn't work .

Two 、 Process drawing

2.1 Use activiti-app Drawing process

Process instance ： Points approval process

2.2 The process node specifies an agent

Each process node needs to specify an agent , That is, the process executes to a task , A designated user is required to approve

Click the task node , Select an agent

There are three ways to appoint agents ：

• 1、 Fixed agent

  

• 2、 Use url Expressions dynamically set delegates

  

• 3、 Use listeners to dynamically set up agents

  

2.3 Except for agents , Node can also set other types of node auditing

Follow up articles to explain

3、 ... and 、 Process saving and Export

preservation ：

export ：

Four 、 technological process bpmn file
