activiti框架API使用技巧

流程引擎的初始化

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

RepositoryService repositoryService = processEngine.getRepositoryService();Deployment deployment = repositoryService.createDeployment()  .addClasspathResource("processes/my-process.bpmn20.xml")  .deploy();

RuntimeService runtimeService = processEngine.getRuntimeService();ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("my-process");

TaskService taskService = processEngine.getTaskService();List<Task> tasks = taskService.createTaskQuery().taskAssignee("kermit").list();

taskService.complete(task.getId());

ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId("my-process-id").singleResult();

HistoryService historyService = processEngine.getHistoryService();List<HistoricProcessInstance> historicProcessInstances = historyService.createHistoricProcessInstanceQuery().finished().list();

RepositoryService repositoryService = processEngine.getRepositoryService();ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().processDefinitionId(processInstance.getProcessDefinitionId()).singleResult();

这些是使用Activiti框架API的基本技巧，可以帮助您在实际开发中更好地使用Activiti框架。
