activiti框架API使用技巧

1. 流程引擎的初始化

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); 

2. 部署流程定义

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

3. 启动流程实例

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

4. 查询任务

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

5. 完成任务

taskService.complete(task.getId()); 

6. 查询流程实例

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

7. 查询历史流程实例

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

8. 获取流程定义信息

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。
