springboot整合activity自動部署及部署文件命名流程

問題描述

springboot整合activity，部署流程定義的時候在數據庫總是會自動的部署一次。

問題分析

查看啟動日志，出現如下一段話：

ProcessEngine default created

Process deployed: {id: myProcess_1:1:db6bacd7-edbd-11ea-b883-1860249fb796, key: myProcess_1, name: null }

在項目啟動的時候流程自動部署

查閱相關資料總結

1.項目中包含流程定義的xml或者bpmn文件，項目在第一次啟動的時候會自動部署。

解決方案

在配置文件中增加如下配置：

#項目隨著spring啟動自動部署
spring.activiti.check-process-definitions=false

刪除數據庫中部署的流程定義，再次啟動項目，沒有出現自動部署的現象。
