4、eate Activiti process engine创建一个流程引擎对象/ProcessEngine processEngine = ProcessEngineConfiguration/.createStandaloneProcessEngineConfiguration()/.buildProcessEngine();/创建一个流程引擎对象(为了便于多册测试，修改 name=;databaseSchemaUpdate; value=;create-drop; 默认为 ture)ProcessEngineprocessEngine=ProcessEngineConfiguration.c

5、reateProcessEngineConfigurationFromRes ource(;activiti.cfg.xml”;).buildProcessEngine();/ Get Activiti servicesrepositoryService/获取流程相关的服务 RepositoryServiceprocessEngine.getRepositoryService();RuntimeService runtimeService = processEngine.getRuntimeService();/ Deploy the process definition/部署相关的流程配置r

6、epositoryService.createDeployment() .addClasspathResource(;diagrams/financialReport.bpmn20.xml”;) .deploy();/ Start a process instance/获取流程实例StringprocId=runtimeService.startProcessInstanceByKey(;financialReport;).getId();/ Get the first task TaskService taskService = processEngine.getTaskService();

7、/获取accountancy组可能要操作的任务List;tasks=taskService.createTaskQuery().taskCandidateGroup(;accountancy;).list(); for (Task task : tasks) System.out.println(;Following task is available for accountancy group: ; + task.getName();/设置 fozzie 代办 claim it taskService.claim(task.getId(), ;fozzie;);/ Verify Fozzie

8、 can now retrieve the task/审核fozzie当前的获取的任务数量 tasks=taskService.createTaskQuery().taskAssignee(;fozzie;).list(); for (Task task : tasks) System.out.println(;Task for fozzie: ; + task.getName();/ Complete the task /设置forzze完毕 taskSplete(task.getId();System.out.println(;Number of tasks for fozzie:; +

9、taskService.createTaskQuery().taskAssignee(;fozzie;).count();/ Retrieve and claim the second task/管理者审核报告并让kermit代办tasks=taskService.createTaskQuery().taskCandidateGroup(;management;).list();for (Task task : tasks) System.out.println(;Following task is available for accountancy group: ; + task.getNa

10、me();taskService.claim(task.getId(), ;kermit;);/ Completing the second task ends the process/完成报告for (Task task : tasks) taskSplete(task.getId();/ verify that the process is actually finished/查询流程实例完成事件HistoryService historyService = processEngine.getHistoryService();HistoricProcessInstance historic

11、ProcessInstance =historyService.createHistoricProcessInstanceQuery().processInstanceId(procId).si ngleResult();System.out.println(;Process instance end time:;+historicProcessInstance.getEndTime();运行结果如下：信息：ProcessEngine default created2011-12-18 17:06:00 org.activiti.engine.impl.jobexecutor.JobAcqui
