请假流程的java源文件如下：

package me.kafeitu.activiti.chapter2;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.repository.ProcessDefinition;
import org.activiti.engine.runtime.ProcessInstance;
import org.junit.Test;

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;

public class VerySimpleLeaveProcessTest {

@Testpublic void testStartProcess() throws Exception {    // 创建流程引擎，使用内存数据库    ProcessEngine processEngine = ProcessEngineConfiguration            .createStandaloneInMemProcessEngineConfiguration()            .buildProcessEngine();    // 部署流程定义文件    RepositoryService repositoryService = processEngine.getRepositoryService();    String processFileName = "me/kafeitu/activiti/helloworld/sayhelloleave.bpmn";    repositoryService.createDeployment().addClasspathResource(processFileName)            .deploy();    // 验证已部署流程定义    ProcessDefinition processDefinition = repositoryService            .createProcessDefinitionQuery().singleResult();    assertEquals("leavesayhello", processDefinition.getKey());    // 启动流程并返回流程实例    RuntimeService runtimeService = processEngine.getRuntimeService();    ProcessInstance processInstance = runtimeService            .startProcessInstanceByKey("leavesayhello");    assertNotNull(processInstance);    System.out.println("pid=" + processInstance.getId() + ", pdid="            + processInstance.getProcessDefinitionId());}

}

其中部署的流程定义文件如下：
