Activity workflow table structure learning

One 、 Seven core interfaces

RepositoryService: Provides a series of tools to manage process deployment and process definition API

RunntimeService: Manage and control process instances when the process is running

TaskService: Manage process tasks , For example, task reminder , Task completion and creation, etc

IdentityService: Provides a way to manage process role data API, These roles include user groups 、 Users and their relationships

ManagementService:  Provide services to manage and maintain the process engine

HistoryService： Operate on the historical data of the process , Including inquiries , Delete these historical data

FormService： Provide form filling service for operation flow

Two 、28 The data structure of a table

act_ge_ The beginning represents the general table ,ge yes general Abbreviation

act_hi_ The beginning represents the historical data table ,hi yes history Abbreviation , Corresponding HistoryService Interface API

act_id_ The beginning represents identity authentication data ,id yes identity Abbreviation , Corresponding IdentityService Interface API

act_re_ The beginning represents the process storage table ,re yes repository Abbreviation , Corresponding RepositoryService Interface API, Store static data of process deployment and process definition

act_ru_ The beginning represents the process operation data table ,ru yes runntime Abbreviation , Corresponding RunntimeService Interface API, Store dynamic data such as process instances and user tasks

Table structure operations ： 
Resource pool process rule table  

• 1) act_re_deployment Deployment information sheet  
• 2) act_re_model Process design model deployment table  
• 3) act_re_procdef Process definition data sheet  

Runtime database tables  

• 1) act_ru_execution Runtime process execution instance table  
• 2) act_ru_identitylink Run time process personnel table , It mainly stores information about task nodes and participants  
• 3) act_ru_task Runtime task node table  
• 4) act_ru_variable Runtime process variable data table  

Historical database tables  

• 1) act_hi_actinst History node table  
• 2) act_hi_attachment Historical attachment table  
• 3) act_ih_comment Historical opinion form  
• 4) act_hi_identitylink Historical process personnel list  
• 5) act_hi_detail Historical details , Provide query of historical variables  
• 6) act_hi_procinst Historical process example table  
• 7) act_hi_taskinst Examples of historical tasks  
• 8) act_hi_varinst Table of historical variables  

Organization chart  

• 1) act_id_group User group information table  
• 2) act_id_info User extended information table  
• 3) act_id_membership User and user group corresponding information table  
• 4) act_id_user User information sheet  

These four tables are very common , Basic organizational management , As for user authentication, it is suggested to develop a set of , The function of the component is too simple , There are many requirements that are difficult to meet in use  
General data sheet  

• 1) act_ge_bytearray Binary data table  
• 2) act_ge_property The attribute data table stores data at the entire process engine level , When initializing the table structure , Three records will be inserted by default

activiti.cfg.xml（activiti Configuration file for ） 

Activiti Core profile , Configure the basic parameters of the process engine creation tool and database connection pool parameters . 
Define database configuration parameters ： 

• jdbcUrl: Database JDBC URL. 
• jdbcDriver: Drivers corresponding to different database types . 
• jdbcUsername: User name to connect to the database . 
• jdbcPassword: Password to connect to the database . 

be based on JDBC Parameter configuration of the database connection Will use the default MyBatis Connection pool . The following parameters can be used to configure the connection pool （ come from MyBatis Parameters ）： 

• jdbcMaxActiveConnections: The maximum number of connections in use in the connection pool . The default is 10. 
• jdbcMaxIdleConnections: The maximum number of idle connections in the connection pool . 
• jdbcMaxCheckoutTime: The longest time the connection has been taken out of use , Over time will be forced to recycle . The default is 20000（20 second ）. 
• jdbcMaxWaitTime: This is an underlying configuration , So that the connection pool can be unable to get a connection for a long time , Print a log , And try again to get a connection .（ Avoid silent operation failure due to wrong configuration ）. The default is 20000（20 second ）.

  Process deployment related table  

• act_re_deployement Deployment object table  
• act_rep_procdef   Process definition form  
• act_ge_bytearray Resource file table

  Process instance related table

•  act_ru_execution Executing object table （ Contains the execution object ID And process instances ID, If there are multiple threads, there may be process instances ID Dissimilarity ）
•  act_hi_procinst Process instance history table
•  act_hi_actinst Store all completed tasks in history

 Task Task related table

•  act_ru_task To do list （ Only the corresponding node is UserTask Of ）
•  act_hi_taskinst The history table of the entrusted tasks （ Only the corresponding node is UserTask Of ） 
•  act_hi_actinst   Activity history table of all nodes （ The activity history of all nodes of the corresponding process , The activities of all nodes from the start node to the end node will be recorded ）

Process variable table

•  act_ru_variable Executing process variable table
•  act_hi_variable Process variable history

3、 ... and 、 The data dictionary

         Save the process definition image and xml、Serializable( serialize ) The variable of , Save all binary data , Pay special attention to class path deployment , Don't put the svn And other hidden files or other files unrelated to the process are also deployed to the table , It will cause some mistakes （ The process definition may not be deleted ）
