Activiti7的使用（七）

2019-12-02 本文已影响0人傻明蚕豆

在之前的文章已经介绍过Activiti7的基本使用，现在就使用springboot整合Activiti7，完成一个完整的请假流程。

Activiti7 发布正式版之后，它与 SpringBoot2.x 已经完全支持整合开发。

Activti7 新支持ProcessRuntime 接口和TaskRuntime 接口，我没有尝试用这两个接口，想用的朋友可以自己研究。

首先创建一个springboot项目，添加Activiti依赖，如下：

<groupId>org.activiti</groupId>

<artifactId>activiti-spring-boot-starter</artifactId>

</dependency>

因为 Activiti7 与 SpringBoot 整合后，默认情况下，集成了 SpringSecurity 安全框架，所以我们就要去准备 SpringSecurity 整合进来的相关用户权限配置信息（该配置我就不贴出来了）。

项目搭建好后，就要画流程图：

整个流程是这样：请假人填写请假信息提交后，就开启一个流程实例，并完成“填写请假信息”任务，然后到“部门主管审批”，审批不通过就返回“填写请假信息”，审批通过并且请假天数小于等于5天，就转到“人事存档”，审批通过并且请假天数大于5天，转到“总经理审批”，经理审批不通过就跳回“填写请假信息”，经理审批通过就转到“人事存档”，“人事存档”完成任务就转到“行政考勤”和“财务统计”，当“行政考勤”和“财务统计”都完成任务，整个流程结束。

下边是流程图的详细信息：

在除了“填写请假信息”外的所有任务，都添加了监听器，作用是在这些任务创建时，添加任务的候选人，然后这些候选人都可以查看到这些任务，然后可以领取任务并完成任务。在排他网关的出口都添加判断条件，这些条件在上面xml中都有。

然后我们启动springboot项目，发现数据库表只有17张，但不影响操作；

首先部署流程：

//部署流程定义

@RequestMapping(value= "deploy/{zipName}")

@ResponseBody

public Respon deploy(@PathVariable(name="zipName")String zipName){

Respon respon=new Respon();

//转化出ZipInputStream流对象

InputStream is = TestController.class.getClassLoader().getResourceAsStream("diagram/"+zipName+".zip");

//将 inputstream流转化为ZipInputStream流

ZipInputStream zipInputStream = new ZipInputStream(is);

//进行部署

Deployment deployment = repositoryService.createDeployment()

.addZipInputStream(zipInputStream).deploy();

//输出部署的一些信息

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

respon.setCode(Constant.CODE_SUCCESS);

respon.setMsg(Constant.CODE_SUCCESS_STRING);

return respon;

}

开始请假

//开始一个请假流程，并完成填写请假申请信息

@RequestMapping(value= "startTest/{userName}/{totalDay}")

@ResponseBody

public Respon startTest(@PathVariable(name="userName")String userName, @PathVariable(name="totalDay")Float totalDay){

Respon respon=new Respon();

String key="qingjia_1";

ProcessInstance processInstance=runtimeService.startProcessInstanceByKey(key);

String processInstanceId=processInstance.getProcessInstanceId();

System.out.println(processInstanceId);

System.out.println("开启了流程实例");

List<Task> list=taskService.createTaskQuery()

.processDefinitionKey(key)//流程实例key

.processInstanceId(processInstanceId)

.list();

for(Task task:list){

System.out.println("任务id："+list.get(0).getId());

System.out.println("任务名称："+list.get(0).getName());

taskService.setAssignee(list.get(0).getId(),userName);

Map<String,Object> map=new HashMap<String,Object>();

map.put("totalDay",totalDay);

map.put("applyUserName",userName);

taskService.complete(task.getId(),map);

//这里完成任务后，监听器马上触发，所以是监听器代码先运行。

System.out.println(userName+"-->完成任务："+task.getId()+"."+task.getName());

}

respon.setData(processInstanceId);

respon.setCode(Constant.CODE_SUCCESS);

respon.setMsg(Constant.CODE_SUCCESS_STRING);

return respon;

}

/**

* Created by Administrator on 2019/11/22.

* 主管监听器

@Component

public class ZhuGuanListener implements TaskListener{

@Override

public void notify(DelegateTask delegateTask) {

System.out.println("进入主管监听器");

System.out.println("新产生任务id："+delegateTask.getId());

System.out.println("新产生任务名称："+delegateTask.getName());

List<String> list=new ArrayList<>();

list.add("主管-诸葛亮");

list.add("副主管-刘伯温");

list.add("副主管-李靖");

delegateTask.addCandidateUsers(list);

}

所有主管都可以查询到相关任务

//查询可选任务

@RequestMapping(value= "listTask/{userName}")

@ResponseBody

public Respon listTask(@PathVariable(name="userName")String userName){

Respon respon=new Respon();

List<Task> list=taskService.createTaskQuery().taskCandidateUser(userName).list();

if(list.size()>0){

String taskId=list.get(0).getId();

System.out.println("任务id："+list.get(0).getId());

System.out.println("任务名称："+list.get(0).getName());

respon.setMsg(taskId);

}else{

respon.setMsg("没有可选任务");

return respon;

}

respon.setCode(Constant.CODE_SUCCESS);

return respon;

}

主管领取并完成任务

//主管领取任务并审批

@RequestMapping(value= "claimTask/{userName}/{taskId}/{flag}/{totalDay}")

@ResponseBody

public Respon claimTask(@PathVariable(name="userName")String userName,@PathVariable(name="taskId")String taskId,@PathVariable(name="flag")String flag,@PathVariable(name="totalDay")Float totalDay){

Respon respon=new Respon();

//flag="_3"驳回；flag="1"通过

Map<String,Object> map=new HashMap<>();

map.put("zhuguanFlag",flag);

map.put("totalDay",totalDay);

taskService.claim(taskId,userName);

taskService.complete(taskId,map);

System.out.println(userName+"：审批任务id："+taskId);

respon.setCode(Constant.CODE_SUCCESS);

respon.setMsg(Constant.CODE_SUCCESS_STRING);

return respon;

}

我这里主管审批通过了，所以下一步就是总经理可以查看到任务

总经理审批任务不通过

//经理领取任务并审批

@RequestMapping(value= "claimTask2/{userName}/{taskId}/{flag}")

@ResponseBody

public Respon claimTask2(@PathVariable(name="userName")String userName,@PathVariable(name="taskId")String taskId,@PathVariable(name="flag")String flag){

Respon respon=new Respon();

//flag="2"驳回；flag="1"通过

Map<String,Object> map=new HashMap<>();

map.put("jingliFlag",flag);

taskService.claim(taskId,userName);

taskService.complete(taskId,map);

System.out.println(userName+"：审批任务id："+taskId);

respon.setCode(Constant.CODE_SUCCESS);

respon.setMsg(Constant.CODE_SUCCESS_STRING);

return respon;

}

审批没通过就返回到“填写请假信息”，我不知道是什么原因，这里驳回不用写其他代码，在网上看过很多驳回的例子都是要写很多东西，但那都是Activiti6及更低的版本，可能Activiti7就不需要。

那现在就查看是否进行到“填写请假信息”这个任务

//查询该流程实例有什么任务

@RequestMapping(value= "processTask/{processInstanceId}")

@ResponseBody

public Respon processTask(@PathVariable(name="processInstanceId")String processInstanceId){

Respon respon=new Respon();

String key="qingjia_1";

List<Task> list=taskService.createTaskQuery().processDefinitionKey(key)//流程实例key

.processInstanceId(processInstanceId).list();

if(list.size()>0){

String taskId=list.get(0).getId();

System.out.println("任务id："+list.get(0).getId());

System.out.println("任务名称："+list.get(0).getName());

respon.setMsg(taskId);

}else{

respon.setMsg("没有可选任务");

return respon;

}

respon.setCode(Constant.CODE_SUCCESS);

return respon;

}

到这里差不多了，剩下的步骤和上面的都类似，所有我就不一一操作，如各位有什么问题和意见都可以提出来，大家一起研究。

最后希望这篇文章能帮到各位学习到更多，谢谢。
