Activiti6：模拟钉钉上⾯的请假流程（使⽤web画图并导出xml然后使⽤java执⾏流程）1.声明当前内容主要为本⼈学习和测试Activiti6这个⼯作流的基本操作，模拟钉钉上⾯的请假流程(简单版)当前内容主要有：1. 使⽤官⽅的web-app⽅式画图2. 将当前流程图导出为xml配置3. 将xml配置导⼊项⽬，并使⽤java⽅式加载并实现流程执⾏2.画出请假执⾏流程图其中都是使⽤最简单的元素重要点：1.启动当前流程需要三个：员⼯名称，请假时间，请假类型例如下⾯参数：此时发起流程就必须这些参数，注意required设置为true流程发起后，通过审核⼈，此时审核⼈需要⼀个参数来执⾏后⾯是否允许请假通过，同样的设置为approve，设置为boolean类型之后流程到了条件判断，这⾥其实就是判断当前的定义的变量approve==true或者approve==false然后后⾯的审核⼈和判断就和这个⼀样即可完成条件判断(所以这⾥省略后⾯的userTask和条件判断)之后到达抄送⼈此时流程执⾏结束保存后(上⾯的请假类型是枚举所以需要在⽣成的xml中修改)3.将画出的图导出为xml⽂件导出内容如下 钉钉上的请假流程 < < formProperty>formProperty>

加载对应的activiti的xml配置⽂件 // ProcessEngine processEngine = aultProcessEngine(); ProcessEngine processEngine = StandaloneInMemProcessEngineConfiguration() .setDatabaseSchemaUpdate(_SCHEMA_UPDATE_TRUE) .setJdbcUrl("jdbc:mysql://localhost:3306/hy_activiti6") .setJdbcDriver("") .setJdbcUsername("root") .setJdbcPassword("root") .setAsyncExecutorActivate(false) .buildProcessEngine(); RepositoryService repositoryService = ositoryService(); Deployment() .addClasspathResource("").deploy(); .println("Number of process definitions: " + ProcessDefinitionQuery().count());

//

创建⼀个雇员的名称为：Kermit发起⼀个请假流程，请1天病假 //

创建⼀个雇员的名称为：Kermit发起⼀个请假流程，请1天病假 String username = "Kermit"; Map variables = new HashMap(); ("username", username); ("type", "illVacation"); ("offWorkDays", 1); RuntimeService runtimeService = timeService(); //

这⾥为发起实际的请假请求 ProcessInstance processInstance = rocessInstanceByKey("OffWork", variables);

// Verify that we started a new process instance n("Number of process instances: " + ProcessInstanceQuery().count());

n("员⼯：" + username + ",发起" + 1 + "天病假的请求");

//

管理组获取所有的任务请求(包括请假等事项) // Fetch all tasks for the management group TaskService taskService = kService(); List tasks = TaskQuery().taskCandidateGroup("management").list(); for (Task task : tasks) { n("Task available: " + e()); }

//

同意请求,让下⼀位进⾏处理 Task offWorkTask = (0); variables = new HashMap(); ("approve", true); te((), variables); n("⼈事部⼈员同意请假请求....");

//

再次获取,下⼀个⼈的执⾏流程 tasks = TaskQuery().taskCandidateGroup("management").list(); for (Task task : tasks) { n("Task available: " + e()); }

//

⼈事部主管同意请求 offWorkTask = (0); variables = new HashMap(); ("approve", true); te((), variables); n("⼈事部主管同意请假请求....");

//系统执⾏抄送任务给当前的经理和秘书

tasks = TaskQuery().taskCandidateGroup("system").list(); for (Task task : tasks) { n("Task available: " + e()); } //

任务完成 offWorkTask = (0); te(()); n("系统⾃动转发当前的请假给总经理和秘书...."); }}执⾏结果：查看数据库结果整个流程执⾏成功！6.总结使⽤官⽅的web app的流程设计器和下载xml⽅式简化了开发步骤，和流程xml的编写，很容易编写(但是要⼩⼼传递的参数问题和判断条件问题)
