流程文件: bookorder.simple.bpmn20.xml

API:

public class SimpleProcessTest {
@Test
public void startBookOrder() {
ProcessEngine processEngine = ProcessEngineConfiguration #1
.createStandaloneInMemProcessEngineConfiguration() #1
.buildProcessEngine(); #1
RuntimeService runtimeService =
processEngine.getRuntimeService();
RepositoryService repositoryService =
processEngine.getRepositoryService();
repositoryService.createDeployment() #2
.addClasspathResource("bookorder.simple.bpmn20.xml") #2
.deploy(); #2
ProcessInstance processInstance = #3
runtimeService.startProcessInstanceByKey( #3
"simplebookorder"); #3
assertNotNull(processInstance.getId());
System.out.println("id " + processInstance.getId() + " " +
processInstance.getProcessDefinitionId());
}
}

API 解析:
ProcessEngineConfiguration
ProcessEngine
    RepositoryService
        Deployment
    RuntimeService
ProcessInstance

3.1
创建流程引擎:
3.1.1 从配置文件配置: activiti.cfg.xml

ProcessEngine processEngine = ProcessEngineConfiguration
   .createProcessEngineConfigurationFromResourceDefault()
   .buildProcessEngine();

3.1.2 代码创建

ProcessEngine processEngine = ProcessEngineConfiguration
   .createStandaloneProcessEngineConfiguration()
   .buildProcessEngine();

Or

ProcessEngine processEngine = ProcessEngineConfiguration
   .createStandaloneInMemProcessEngineConfiguration()
   .buildProcessEngine();
