Activiti-02 基本操作

Posted 2020-08-28 Devan.Yan

1.创建系统需要的25张数据表；

配置数据库连接

activiti.cfg.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans.xsd">

  <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">

        .taskAssignee(assignee)
        .list();
        for(Task task:tasklist){
            System.out.println(task.getName());
            System.out.println(task.getId());
            System.out.println("-------------");
        }
        return tasklist;
    }
    /**

     */
    public void runTime(){
        String processKey = "myProcess";
        RuntimeService runtimeService = pe.getRuntimeService();
        runtimeService.startProcessInstanceByKey(processKey);
    }
    
    /**
     * #2、部署一个 流程
     */
    public void deploy(){
        RepositoryService repositoryService = pe.getRepositoryService();//获得Service
        repositoryService.createDeployment()//创建部署对象
        .addClasspathResource("bpmn/mainBpmn.bpmn")
        .addClasspathResource("bpmn/mainBpmn.png")
        .name("测试流程")
        .deploy();//部署
        
    }
    
    /**
     * #1、创建流程引擎
     */
    public void buildProcessEngine(){
        //活的流程引擎配置信息
        ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResourceDefault();
        //创建流程引擎
        processEngineConfiguration.buildProcessEngine();
    }
}

 

运行后、数据库会生成25张数据表
