activiti中核心类就是ProcessEngine流程引擎，与spring整合后，就是通过spring来管理ProcessEngine，创建spring与activiti的整合配置文件：activiti-spring.xml，名称不固定

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:activiti-spring.xml")
public class Test01 {

    @Autowired
    private RepositoryService repositoryService;

    
    @Test
    public void deployment() {
        Deployment deployment = repositoryService.createDeployment()
                .name("activiti整合spring")
                .key("activiti-spring1")
                .addClasspathResource("bpmn/activiti-spring.bpmn20.xml")
                .deploy();

        System.out.println(deployment.getId());
        System.out.println(deployment.getName());
    }

    @Autowired
    private RuntimeService runtimeService;

    
    @Test
    public void startProcess() {
        ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("activiti-spring");
        System.out.println(processInstance.getProcessDefinitionKey());
        System.out.println(processInstance.getProcessInstanceId());
        System.out.println(processInstance.getName());

    }
}

1. 加载activiti-spring.xml文件。
2. 加载SpringProcessEngineConfiguration对象，这个对象需要依赖注入DataSource和TransactionManager对象。
3. 加载ProcessEngineFactoryBean工厂对象来创建ProcessEngine对象，而ProcessEngineFactoryBean工厂对象需要依赖注入ProcessEngineConfiguration对象。
4. ProcessEngine对象负责创建activiti中的业务service对象，比如：RepositoryService，RuntimeService，TaskService等，从而简化activiti的开发过程。
