【Activiti-02】 基本操作

1.创建系统需要的25张数据表；

配置数据库连接

activiti.cfg.xml

    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
