springboot集成activiti全過(guò)程
更新時(shí)間：2025年10月31日 10:06:06 作者：zengsange
文章介紹了在Spring Boot中集成Activiti時(shí)的配置和使用方法,包括在`pom.xml`中添加依賴、將`activiti.cfg.xml`文件放在`resources`目錄下、以及配置各種監(jiān)聽(tīng)器來(lái)監(jiān)聽(tīng)流程的不同階段

注解 需要用到activiti.xfg.xml 吧activiti.xfg.xml放到resources目錄下 不然processEngine 會(huì)報(bào)null
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
activiti.xfg.xml內(nèi)容
