工作流和工作流引擎是什么东西?
在本教程中,您将学习如何使用 Camunda Modeler 创建第一个 BPMN 2.0 流程,源码并了解如何执行自动化步骤。源码首先,源码快速kd指标源码打开 Camunda Modeler 并创建一个新的源码 BPMN 图。 为了开始构建流程,源码请进行以下步骤: 双击 Start Event,源码将其命名为“Payment Retrieval requested”。源码确保使用 Shift + Enter 添加换行。源码 将启动事件拖放到画布上,源码命名为“Charge Credit Card”。源码c 源码封装将其更改为服务任务。源码 添加“Payment Received”作为结束事件。源码 配置服务任务时,源码选择外部任务模式,源码并确保“可执行文件”属性被勾选。源码检测资质 为进程定义 ID(例如,payment-retrieval)和名称(例如,Payment Retrieval),并保存图表为“payment.bpmn”。下载 BPMN 模型。钢铁订单源码 实现外部任务辅助角色,使用 Camunda 平台根据项目需求选择合适语言(Java 或 JavaScript)。对于 Java 开发者,首先确保安装 JDK 1.8 和 IDE(如 Eclipse)。创建 Maven 项目,棋牌源码租用配置依赖项,添加 Camunda 外部任务客户端。实现 ExternalTaskClient,运行并部署流程。使用 Camunda Modeler 或 Cockpit 验证部署状态。 部署流程后,启动一个新的实例,观察流程是否正常运行。使用 Camunda REST API 或 curl 发送 POST 请求来启动流程实例。在 Cockpit 中监控流程实例的状态。 源代码和文档可在 GitHub(github.com/camunda/camu...)和官方文档(docs.camunda.org/get-st...)中获取。 以上步骤演示了 Camunda 流程引擎的基本使用方法,了解如何设计自动化和人工参与流程,配置表单,以及部署流程实例。云程低代码平台提供了丰富的功能扩展,可在线体验更多功能()。activitiå¨çº¿è®¾è®¡-Activiti6.0ä¸å¦ä½è®¾è®¡åå ³è表åï¼
