几天第一次接触activiti
今天接触了activiti工作流框架。
看了看终于把自己的第一个helloworld给写出来了
,有一点收获感。
?
?
但是还是有好多东西不明白的，找资料，关于这方面的又少，分享一下，希望哪位大神可以知道一下.....
?
首先呢，我西安说一下，写这个helloworld容易出错的地方吧，
?
第一点呢，就是HelloWorld.bpmn20.xml 。这个很容易出错，当用eclipse创建了一个activiti Diagram后，名字还要自己改成后缀名为xml的文档，而默认的名字 name.bpmn也的在bpmn后面加上20.这个不知道是什么情况，应该是默认的....
?
第二点呢，就是在写test类的时候
repositoryService.createDeployment().addClasspathResource("hello/HelloWorld.bpmn20.xml").deploy();
?
老师后面送的deploy忘记写上，那样额话改改报no processes deploy了，所以呢，大家如果新学得注意一下了。
?
最后还有几个问题，希望看到的大神们帮我解答一下。

package hello;import static org.junit.Assert.*;import org.activiti.engine.ProcessEngine;import org.activiti.engine.ProcessEngineConfiguration;import org.activiti.engine.RepositoryService;import org.activiti.engine.RuntimeService;import org.activiti.engine.TaskService;import org.activiti.engine.runtime.ProcessInstance;import org.activiti.engine.task.Task;import org.junit.Test;public class HelloWorldTest {@Testpublic void test() {ProcessEngineConfiguration processEngineConfiguration=ProcessEngineConfiguration.createProcessEngineConfigurationFromResourceDefault();ProcessEngine processEngine=processEngineConfiguration.buildProcessEngine();RepositoryService repositoryService=processEngine.getRepositoryService();RuntimeService runtimeService=processEngine.getRuntimeService();TaskService taskService=processEngine.getTaskService();repositoryService.createDeployment().addClasspathResource("hello/HelloWorld.bpmn20.xml").deploy();ProcessInstance processInstance=runtimeService.startProcessInstanceByKey("process1");Task task=taskService.createTaskQuery().singleResult();System.out.println(task.getName());taskService.complete(task.getId());task = taskService.createTaskQuery().singleResult();System.out.println(task.getName());}}?taskService.complete(task.getId());

这句代码不是很了解，请帮我解答一下，下面是我的流程图。
