Activit工作流引擎核心数据表存储解剖

假设: 某公司的员工请假单审批流程是 发起者-->部门主管--->部门经理 共三个节点

发起者:公司所有的用户
部门主管:aaa(审批)
部门经理:bbb(审批)

java 　Activiti工作流引擎共有23张数据表用来存储审批　　这里我只是使用了核心的几张表

第一步:发布流程定义

发布定义员工请假申请单流程

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_ = '员工请假申请单',
category_ = NULL,
deploy_time_ = '2018-02-09 20:23:36';

mysql>  select * from act_re_deployment;
+-----+--------------+-----------+-------------------------+
| ID_ | NAME_        | CATEGORY_ | DEPLOY_TIME_            |
+-----+--------------+-----------+-------------------------+
| 1   | 员工请假申请单 | NULL      | 2018-02-09 20:23:36　|
+-----+--------------+-----------+-------------------------+
1 row in set

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

mysql>  INSERT INTO `act_ge_bytearray` SET id_='2',
rev_= 1,
name_= 'diagram/diagram.bpmn',
bytes_= _binary'<?xml..?>..中间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
category_: http://www.activiti.org/test name_: my process

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
1 row in set (0.00 sec)

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

第二步:员工发起请假流程审批实例

通过流程定义 processDefinitionKey 来启动一个流程流程
=========================================================================

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

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