Processengines container of activiti

Processengines consists of one or more processengine and processengineinfo corresponding to processengine.

Each processengine corresponds to one processengineinfo.

 

 

 

Each processengine is created through a configuration file activiti. properties. The activiti. properties configuration contains a process. Engine. Name to uniquely identify the process engine.

The parsing of activiti. properties is completed by dbprocessenginebuilder. After dbprocessenginebuilder parses the file, it creates the processengineconfiguration instance and saves the default Implementation of persistencesessionfactory ibatispersistencesessionfactory to the processengineconfiguration instance.

 

When processengine is created, the processengineconfiguration instance is passed in as a parameter and a processengineimpl instance is returned.

 

A brief diagram of the process for creating each process instance:

 

A processengineconfiguration contains all the service components required by the process engine,

 

In processengine and processengineimpl, only some components are exposed and visible to the outside. For example, procesengine and processengineimpl are externally exposed components that can be acquired.
