Activiti的画图插件的安装
工作流的流程步骤
（1）画出业务流程图
（2）部署流程
（3）启动流程实例
（4）查询当前办理人的个人任务
（5）完成任务
业务流程图（学生请假）
创建Activiti的表，Activiti跟Spring结合，在项目初始化就可以创建了
部署流程的两种方式（）
/**
* 部署流程定义使用ClassPath方式（添加）
* 表的变化：
* act_re_deployment 流程部署表
* act_re_procdef 流程定义表
* act_ge_bytearray 资源文件表
* act_ge_property 系统配置表
* */
@Test
public void TestflowWithClassPath(){
private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();//获取流程引擎对象（Activiti的核心对象）
Deployment deployment = processEngine.getRepositoryService() //根据调用流程引擎对象的RepositoryService方法获得 deployment 对象
.createDeployment()
.addClasspathResource("diragrams/studentLeaveProcess.bpmn")
.addClasspathResource("diragrams/studentLeaveProcess.png")
.name("学生请假流程")
.deploy();
//查询流程部署表（以下数据信息）
System.out.println("流程部署id:"+deployment.getId());
System.out.println("流程部署名称:"+deployment.getName());
}
/**
* 部署流程定义使用Zip方式（添加）
*
*
*
* */
@Test
public void TestFlowWithZip(){
InputStream inputStream = this.getClass() //获取当前类对象
.getClassLoader() //获取类加载器
.getResourceAsStream("diragrams/HelloWord.zip"); //获取指定文件资源
ZipInputStream zipInputStream = new ZipInputStream(inputStream);
Deployment deployment = processEngine.getRepositoryService()
.createDeployment().addZipInputStream(zipInputStream)
.name("lmy1")
.deploy();
System.out.println("流程部署id:"+deployment.getId());
System.out.println("流程部署名称:"+deployment.getName());
}
启动流程
/**
* 启动流程实例
* 表的变化：
* act_ru_excutioon 执行对象表
* act_ru_identitylink 身份联系表
* act_ru_task 任务表
* act_hi_actinst 活动节点历史表
* act_hi_identitylink 身份联系历史表
* act_hi_procinst 流程实例历史表
* act_hi_taskinst 历史任务表
* */
@Test
public void Start(){
// RuntimeService：在Activiti中，每当一个流程定义被启动一次之后，都会生成一个相应的流程对象实例。RuntimeService提供了启动流程、查询流程实例、设置获取流程实例变量等功能。此外它还提供了对流程部署，流程定义和流程实例的存取服务。
ProcessInstance pi = processEngine.getRuntimeService() //使用流程定义的key启动流程
.startProcessInstanceByKey("myFirstProcess");
System.out.println("流程实例id:"+pi.getId());
System.out.println("流程定义id:"+pi.getProcessDefinitionId());
}
查询当前人的任务
@Test
public void Tasklmy(){
// TaskService: 在Activiti中业务流程定义中的每一个执行节点被称为一个Task，对流程中的数据存取，状态变更等操作均需要在Task中完成。TaskService提供了对用户Task 和Form相关的操作。它提供了运行时任务查询、领取、完成、删除以及变量设置等功能。
List<Task> taskList = processEngine.getTaskService()
.createTaskQuery()
.taskAssignee("lmy")
.list();
for (Task task:taskList) {
System.out.println("任务id"+task.getId());
System.out.println("任务name"+task.getName());
System.out.println("任务创建时间"+task.getCreateTime());
System.out.println("任务委派人"+task.getAssignee());
System.out.println("流程实例id"+task.getProcessInstanceId());
}
}
完成任务
/**
* 结束流程
* 表的变化：
* 带有re_的数据清空
* 历史表的（hi_）数据修改或者添加
*
*
* */
@Test
public void completeTask(){
processEngine.getTaskService()
.complete("25004");//任务的id
}
