3.1
创建流程引擎:
3.1.1 从配置文件配置: activiti.cfg.xml

ProcessEngine processEngine = ProcessEngineConfiguration
   .createProcessEngineConfigurationFromResourceDefault()
   .buildProcessEngine();

3.1.2 代码创建

ProcessEngine processEngine = ProcessEngineConfiguration
   .createStandaloneProcessEngineConfiguration()
   .buildProcessEngine();

Or

ProcessEngine processEngine = ProcessEngineConfiguration
   .createStandaloneInMemProcessEngineConfiguration()
   .buildProcessEngine();
