0.springboot项目创建
通过https://start.spring.io/生成纯净的一个springboot工程
1.引入activiti相关依赖

<dependency> <groupid>org.activiti</groupid> <artifactid>activiti-spring-boot-starter</artifactid> <version> 7.1 . 0 .m6</version> </dependency> |
2.启动工程并创建activiti数据库
##activiti7中使用spring security,因此启动工程前,需要加入2个文件支持,2个文件的代码如下:

##启动springboot工程,让系统启动时帮我们建好25张表 2.安装activiti插件(设计器) ##idea
file->settings->plugins,然后找actibpm进行安装。
##流程图中乱码问题先提前设置防止:
修改idea64.exe.vmoptions文件,在文件中加上如下,然后重启idea
-dfile.encoding=utf-8
##进行流程设计
file->new->bpmnfile
设计好后,修改process1.bpmn成process1.xml,然后右键export file导出成process1.jpg,再将process1.bpmn修改成process1.bpmn20.xml,最后将2个文件放在process文件夹
3.流程部署
使用activiti提供的api把流程定义内容存储起来,activiti执行把流程定义内容存储在数据库中。

package cn.gzsendi.activitidemotest; /** * created by jxlhl on 2021/8/18. */ import org.activiti.engine.repositoryservice; import org.activiti.engine.repository.deployment; import org.activiti.engine.repository.deploymentbuilder; import org.junit.test; import org.junit.runner.runwith; import org.springframework.beans.factory.annotation.autowired; import org.springframework.boot.test.context.springboottest; import org.springframework.test.context.junit4.springrunner; @runwith (springrunner. class ) @springboottest public class springbootjunittest { //得到repositoryservice实例 @autowired private repositoryservice repositoryservice; //0.流程部署,单个文件部署方式 @test public void testdeployment(){ //使用repositoryservice进行部署 deploymentbuilder builder = repositoryservice.createdeployment(); builder.addclasspathresource( "process/process1.bpmn20.xml" ); builder.addclasspathresource( "process/process1.jpg" ); builder.name( "first_activiti_process" ); deployment deployment = builder.deploy(); //输出部署信息 system.out.println( "流程部署id:" + deployment.getid()); system.out.println( "流程部署名称:" + deployment.getname()); //流程部署id:125098e1-ffd9-11eb-8847-02004c4f4f50 //流程部署名称:first_activiti_process } } |
执行此操作后activiti会将上边代码中指定的bpmn20文件和图片文件保存在activiti数据库。
流程定义部署后操作activiti的3张表
4.流程实例启动
启动一个流程实例表示开始一次业务流程的运行

5.任务查询
流程启动后,任务的负责人就可以查询自己当前需要处理的任务,查询出来的任务都是该用户的待办任务。
