springboot整合activity自动部署及部署文件命名流程
问题描述
springboot整合activity,部署流程定义的时候在数据库总是会自动的部署一次。
问题分析
查看启动日志,出现如下一段话:
ProcessEngine default created
Process deployed: {id: myProcess_1:1:db6bacd7-edbd-11ea-b883-1860249fb796, key: myProcess_1, name: null }
在项目启动的时候流程自动部署
查阅相关资料总结
1.项目中包含流程定义的xml或者bpmn文件,项目在第一次启动的时候会自动部署。
解决方案
在配置文件中增加如下配置:
#项目随着spring启动自动部署
spring.activiti.check-process-definitions=false
删除数据库中部署的流程定义,再次启动项目,没有出现自动部署的现象。

看看演示吧
启动程序会自动初始化Activiti所用的数据库和我们的业务数据库,并自动发布我们的流程。
此时我们要加入的公司id为1,申请加入的人的id为2,使用PostMan访问http://localhost:8080/process/2/1 此时数据库发生如下变化
此时用户admin和wtr具备审批申请的权利,此时我们访问http://localhost:8080/tasks?assignee=admin 查看admin用户的任务,返回结果为:
[
{
"id":"10",
"name":"Approval Task"
}
]
我们现在通过访问http://localhost:8080/complete/true/10 完成任务,true为同意(可以选择false),10为task的id,任务完成后会自动调用Service Task,此时wyf这条记录的comp_compId为更新为当前公司的id。
以上为个人经验,希望能给大家一个参考,也希望大家多多支持编程网。
