Flowable可视化流程设计器Flowable BPMN visualizer

本文主要是介绍Flowable可视化流程设计器Flowable BPMN visualizer，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.安装IDEA插件`Flowable BPMN visualizer`

IDEA插件市场中搜索Flowable BPMN visualizer安装该插件
在这里插入图片描述

2.创建流程图

2.1.创建流程图文件

在resources下创建myProcess.bpmn20.xml流程图。

创建时名称只用输入myProcess

2.2.创建流程图

在这里插入图片描述

选中myProcess.bpmn20.xml，右键打开流程图设计界面
设计流程图
流程名称和id

创建开始事件

创建用户任务

指定任务责任人zhangsan和lisi

创建结束事件

连线

2.3.部署和执行流程

依次执行下列方法

public class Test02 {ProcessEngineConfiguration configuration = null;@Beforepublic void before(){// 获取  ProcessEngineConfiguration 对象configuration = new StandaloneProcessEngineConfiguration();// 配置 相关的数据库的连接信息configuration.setJdbcDriver("com.mysql.cj.jdbc.Driver");configuration.setJdbcUsername("root");configuration.setJdbcPassword("123456");configuration.setJdbcUrl("jdbc:mysql://localhost:3306/flowable-learn?serverTimezone=UTC&nullCatalogMeansCurrent=true");// 如果数据库中的表结构不存在就新建configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);}/*** 部署流程**/@Testpublic void testDeploy(){// 1.获取 ProcessEngine 对象ProcessEngine processEngine = configuration.buildProcessEngine();// 2.获取RepositoryServiceRepositoryService repositoryService = processEngine.getRepositoryService();// 3.完成流程的部署操作Deployment deploy = repositoryService.createDeployment()// 创建Deployment对象.addClasspathResource("myProcess.bpmn20.xml") // 添加流程部署文件.name("请假流程") // 设置部署流程的名称.deploy(); // 执行部署操作System.out.println("deploy.getId() = " + deploy.getId());System.out.println("deploy.getName() = " + deploy.getName());}/*** 启动流程实例*/@Testpublic void testRunProcess(){ProcessEngine processEngine = configuration.buildProcessEngine();// 我们需要通过RuntimeService来启动流程实例RuntimeService runtimeService = processEngine.getRuntimeService();// 启动流程实例ProcessInstance holidayRequest = runtimeService.startProcessInstanceById("myProcess:4:145004"); //从库中act_re_procdef表查看该值System.out.println("holidayRequest.getProcessDefinitionId() = " + holidayRequest.getProcessDefinitionId());System.out.println("holidayRequest.getActivityId() = " + holidayRequest.getActivityId());System.out.println("holidayRequest.getId() = " + holidayRequest.getId());}/*** 查询和完成zhangsan任务*/@Testpublic void testQueryTask(){ProcessEngine processEngine = configuration.buildProcessEngine();TaskService taskService = processEngine.getTaskService();List<Task> list = taskService.createTaskQuery().processDefinitionKey("myProcess") // 指定查询的流程编程.taskAssignee("zhangsan") // 查询这个任务的处理人.list();for (Task task : list) {System.out.println("task.getProcessDefinitionId() = " + task.getProcessDefinitionId());System.out.println("task.getName() = " + task.getName());System.out.println("task.getAssignee() = " + task.getAssignee());System.out.println("task.getDescription() = " + task.getDescription());System.out.println("task.getId() = " + task.getId());taskService.complete(task.getId());}}/*** 完成lisi当前任务*/@Testpublic void testCompleteTask(){ProcessEngine processEngine = configuration.buildProcessEngine();TaskService taskService = processEngine.getTaskService();List<Task> list = taskService.createTaskQuery().processDefinitionKey("myProcess").taskAssignee("lisi").list();for (Task task : list) {// 完成任务taskService.complete(task.getId());}}/*** 获取流程任务的历史数据*/@Testpublic void testHistory(){ProcessEngine processEngine = configuration.buildProcessEngine();HistoryService historyService = processEngine.getHistoryService();List<HistoricActivityInstance> list = historyService.createHistoricActivityInstanceQuery().processDefinitionId("myProcess:4:145004").finished() // 查询的历史记录的状态是已经完成.orderByHistoricActivityInstanceEndTime().asc() // 指定排序的字段和顺序.list();for (HistoricActivityInstance history : list) {System.out.println(history.getActivityName()+":"+history.getAssignee()+"--"+history.getActivityId()+":" + history.getDurationInMillis()+"毫秒");}}
