一:绘制流程图

 

 二.将流程图后缀名更改为xml 生成uml图并保存为png

 

 生成此图片

 

 三:创建流程

    public static void main(String[] args) {
        ProcessEngineConfiguration processEngineConfigurationFromResource = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
        ProcessEngine processEngine = processEngineConfigurationFromResource.buildProcessEngine();

        RepositoryService repositoryService = processEngine.getRepositoryService();
        repositoryService.createDeployment()
                .addClasspathResource("bpmn/holiday.bpmn")
                .addClasspathResource("bpmn/holiday.png")
                .name("创建流程")
                .deploy();
    }
