Required JAR Packages:

The necessary jar packages, database-driven jar packages, and Mybatis-3.2.2.jar on the website Lib

Activiti Operation Flow:

1. Flowchart actions: Define, deploy, view, delete

2. Business operations: Start the business (also specify the next task operator), process related business (a. Process variables, B, fields in the table Business_key), query personal business, dynamically specify the next task Manager (self-closing to get the current user's superiors), Transact business (write the URL to the diagram, Dynamically get formkey at execution time by configuring the Action return value $ (#url), Query Task (task ID----->taskid------>business_key------------> Request form Information)

Note: Activiti can query the business using the fields in the process table, or you can query the process ID based on the business ID
