- 然后从自己目录下把项目克隆到本地
- 切换分支>git checkout -b study6 activiti-6.0.0
- 编译>mvn clean test-compile
- 导入到编辑器
Activiti6.0模块介绍
- module/activiti-engine 核心模块
- module/activiti-spring Spring集成模块
- module/activiti-sping-boot SpringBoot集成模块
- module/activiti-rest 对外提供rest api模块
- module/activiti-form-engine 表单引擎模块
- module/activiti-ldap 集成ldap用户的模块
基于源码activiti-app运行
启动cativiti-app
cd modules/activiti-ui/activiti-app
mvn clean tomcat7:run
打开浏览器访问http://127.0.0.1:9999/activiti-app/
activiti-ui
- activiti-app 集成发布的war工程
- activiti-app-conf UI独立于业务外的配置
- activiti-app-logic UI的业务逻辑
- activiti-app-rest 提供接口的rest api
Activiti6.0初体验helloword
通过activiti-app画好流程图并设置属性
- id:startEvent | name:开始
- id:submitForm | name:填写审批信息
- id:decideSubmit | name:提交OR取消
- id:endEventCancel | name:取消
- id:tl_approve | name:主管审批
- id:decideTLApprove | name:主管审批校验
- id:hr_approve | name:人事审批
- id:decideHRApprove | name:人事审批校验
- id:endEvent |name:结束
设置form表单信息
填写审批信息表单
主管审批表单
hr审批表单
设置流转条件
提交or取消:
- ${submitType=="y"||submitType=="Y"}
- ${submitType=="n"||submitType=="N"}
主管审批校验:
- ${tlApprove=="y"||tlApprove=="Y"}
- ${tlApprove=="n"||tlApprove=="N"}
人事审批校验:
- ${hrApprove=="y"||hrApprove=="Y"}
- ${hrApprove=="n"||hrApprove=="N"}
导出工作流xml文件创建demoActiviti项目
- 把导入文件放入项目里
- 引入jar包
