Activit工作流引擎核心數據表存儲解剖

歷史記錄 www update let def 流程實例 aaa delete nes

假設: 某公司的員工請假單審批流程是 發起者-->部門主管--->部門經理 共三個節點


發起者:公司所有的用戶

部門主管:aaa(審批)

部門經理:bbb(審批)


java  Activiti工作流引擎共有23張數據表用來存儲審批  這裏我只是使用了核心的幾張表



第一步:發布流程定義

發布定義員工請假申請單流程

mysql>  UPDATE act_ge_property 
	SET    rev_ = 2, 
	       value_ = '101' 
	WHERE  name_ = 'next.dbid' 
	       AND rev_ = 1; 

mysql>  select * from act_ge_property;
+----------------+--------------+------+
| NAME_          | VALUE_       | REV_ |
+----------------+--------------+------+
| next.dbid      | 101          |    2 |
| schema.history | create(5.12) |    1 |
| schema.version | 5.12         |    1 |
+----------------+--------------+------+
3 rows in set

=========================================================================

mysql>  INSERT INTO `act_re_deployment` 
SET id_ = '1', 
    name_ = '員工請假申請單', 
    category_ = NULL, 
    deploy_time_ = '2018-02-09 20:23:36'; 

mysql>  select * from act_re_deployment;

+-----+--------------+-----------+-------------------------+
| 1   | 員工請假申請單 | NULL      | 2018-02-09 20:23:36 |
+-----+--------------+-----------+-------------------------+
1 row in set

=========================================================================

mysql>  INSERT INTO `act_ge_bytearray` SET id_='2',

            name_= 'diagram/diagram.bpmn', 
            bytes_= _binary'<?xml..?>..中間xml省去..</definitions>', 
            deployment_id_= '1', 
            generated_= 0;

=========================================================================

mysql>  INSERT INTO `act_re_procdef` 
	SET id_ = 'myprocess:1:4', 
	    rev_ = 1, 
	    category_ = 'http://www.activiti.org/test', 
	    name_ = 'my process', 
	    key_ = 'myprocess', 
	    version_ = 1, 
	    deployment_id_ = '1', 
	    resource_name_ = 'diagram/diagram.bpmn', 
	    dgrm_resource_name_ = 'diagram/diagram.png', 
	    description_ = NULL, 
	    has_start_form_key_ = 0, 
	    suspension_state_ = 1; 

mysql>  select * from `act_re_procdef`\g;
*************************** 1. row ***************************
                id_: myprocess:1:4
               rev_: 1

              name_: my process

1 row in set (0.00 sec)

第二步:員工發起請假流程審批實例

通過流程定義 processDefinitionKey 來啟動一個流程流程
=========================================================================

mysql>  UPDATE act_ge_property 
	SET    rev_ = 3, 
	       value_ = '201' 
	WHERE  name_ = 'next.dbid' 
	       AND rev_ = 2; 

mysql>  select * from act_ge_property;
+----------------+--------------+------+
| NAME_          | VALUE_       | REV_ |
+----------------+--------------+------+
| next.dbid      | 201          |    3 |
| schema.history | create(5.12) |    1 |
| schema.version | 5.12         |    1 |
+----------------+--------------+------+
3 rows in set

=========================================================================
向流程實例表插入一條數據
