activiti7使用一

目录

一、Activiti环境

1、idea安装插件
* Bpmn图形其实是通过xml表示业务流程（.bpmn文件使用文本编辑器打开）
* File | Settings | Plugins
    - 搜索actiBPM（Activiti BPMN visualizer）
2、数据库支持
* 阿里云PolarDB
    - 集群白名单
        ~ 新增ip白名单分组（www.ip138.com）
        ~ 选择安全组
    - 账号管理
        ~ 创建账号
    - 基本信息
        ~ 链接地址（主地址申请公网）
        ~ 登录数据库
* 创建数据库（名字任意）
    - CREATE DATABASE activiti DEFAULT CHARACTER SET utf8;
3、创建maven工程

5、流程定义部署
public class ActivitiDemo {
  @Test
  public void testDeployment() {
    // 改动四张表：act_re_deployment、act_re_procdef、act_ge_bytearray、act_ge_property
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    Deployment deploy = repositoryService
            .createDeployment()
            .name("出差申请流程")
            .addClasspathResource("bpmn/evection.bpmn20.xml")
            .addClasspathResource("bpmn/evection.png")
            .deploy();
    System.out.println("流程部署id=" + deploy.getId());
    System.out.println("流程部署名字=" + deploy.getName());
  }
}
6、启动流程-任务查询-完成任务
public class ActivitiDemo {
  @Test
  public void testStartProcess() {
    // 启动流程
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RuntimeService runtimeService = processEngine.getRuntimeService();
    ProcessInstance instance = runtimeService.startProcessInstanceByKey("evection");
    System.out.println("流程定义ID：" + instance.getProcessDefinitionId());
    System.out.println("流程实例ID：" + instance.getId());
    System.out.println("当前活动的ID：" + instance.getActivityId());
  }

  @Test
  public void testFindPersonalTaskList() {
    // 任务查询
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    List<Task> taskList = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("zhangsan").list();
    for (Task task : taskList) {
      System.out.println("流程实例id=" + task.getProcessInstanceId());
      System.out.println("任务Id=" + task.getId());
      System.out.println("任务负责人=" + task.getAssignee());
      System.out.println("任务名称=" + task.getName());
    }
  }

  @Test
  public void completTask() {
    // 完成任务
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    // taskService.complete("7505");
    // Task task = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("jerry").singleResult();
    // Task task = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("jack").singleResult();
    Task task = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("rose").singleResult();
    System.out.println("流程实例id=" + task.getProcessInstanceId());
    System.out.println("任务Id=" + task.getId());
    System.out.println("任务负责人=" + task.getAssignee());
    System.out.println("任务名称=" + task.getName());
    taskService.complete(task.getId());
  }
}
7、zip方式进行流程部署
public class ActivitiDemo {
  @Test
  public void deployProcessByZip() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("bpmn/evection.zip");
    ZipInputStream zipInputStream = new ZipInputStream(inputStream);
    Deployment deploy = repositoryService.createDeployment().addZipInputStream(zipInputStream).deploy();
    System.out.println("流程部署id=" + deploy.getId());
    System.out.println("流程部署的名称=" + deploy.getName());
  }
}
8、流程的查询和删除
public class ActivitiDemo {
  @Test
  public void queryProcessDefinition() {
    // 流程查询
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    ProcessDefinitionQuery definitionQuery = repositoryService.createProcessDefinitionQuery();
    List<ProcessDefinition> definitionList = definitionQuery.processDefinitionKey("myEvection").orderByProcessDefinitionVersion().desc().list();
    for (ProcessDefinition processDefinition : definitionList) {
      System.out.println("流程定义ID：" + processDefinition.getId());
      System.out.println("流程定义名称:" + processDefinition.getName());
      System.out.println("流程定义Key:" + processDefinition.getKey());
      System.out.println("流程定义版本:" + processDefinition.getVersion());
      System.out.println("流程部署ID:" + processDefinition.getDeploymentId());
    }
  }

  @Test
  public void deleteDeployMent() {
    // 流程删除
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    String deploymentId = "2501";
    // 当前流程如果没有完成，想要删除的话需要使用特殊方式，原理就是：级联删除
    repositoryService.deleteDeployment(deploymentId, true);
  }
}
9、流程资源下载
public class ActivitiDemo {
  @Test
  public void getDeployment() throws IOException {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().processDefinitionKey("myEvection").singleResult();
    String deploymentId = processDefinition.getDeploymentId();
    // 从数据库获取流
    String pngName = processDefinition.getDiagramResourceName();
    InputStream pngInput = repositoryService.getResourceAsStream(deploymentId, pngName);
    String bpmnName = processDefinition.getResourceName();
    InputStream bpmnInput = repositoryService.getResourceAsStream(deploymentId, bpmnName);
    // 传输流
    File pngFile = new File("E:\\study\\ll-activiti\\evection.png");
    File bpmnFile = new File("E:\\study\\ll-activiti\\evection.bpmn20.xml");
    FileOutputStream pngOutputStream = new FileOutputStream(pngFile);
    FileOutputStream bpmnOutputStream = new FileOutputStream(bpmnFile);
    IOUtils.copy(pngInput, pngOutputStream);
    IOUtils.copy(bpmnInput, bpmnOutputStream);
    pngOutputStream.close();
    bpmnOutputStream.close();
    pngInput.close();
    bpmnInput.close();
  }
}
10、查看历史信息
public class ActivitiDemo {
  @Test
  public void findHistoryInfo() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    HistoryService historyService = processEngine.getHistoryService();
    HistoricActivityInstanceQuery instanceQuery = historyService.createHistoricActivityInstanceQuery();
    // instanceQuery.processInstanceId("12501");
    instanceQuery.processDefinitionId("myEvection:1:10004");
    instanceQuery.orderByHistoricActivityInstanceStartTime().asc();
    List<HistoricActivityInstance> activityInstanceList = instanceQuery.list();
    for (HistoricActivityInstance hi : activityInstanceList) {
      System.out.println(hi.getActivityId());
      System.out.println(hi.getActivityName());
      System.out.println(hi.getProcessDefinitionId());
      System.out.println(hi.getProcessInstanceId());
      System.out.println("<==========================>");
    }
  }
}
11、任务挂起与激活
public class ActivtiBusinessDemo {
  @Test
  public void addBusinessKey() {
    // 实现businessKey的关联
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RuntimeService runtimeService = processEngine.getRuntimeService();
    ProcessInstance instance = runtimeService.startProcessInstanceByKey("myEvection", "1001");
    System.out.println("businessKey==" + instance.getBusinessKey());
  }

  @Test
  public void suspendAllProcessInstance() {
    // 实现流程定义的全部挂起与激活
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().processDefinitionKey("myEvection").singleResult();
    boolean suspended = processDefinition.isSuspended();
    String definitionId = processDefinition.getId();
    if (suspended) {
      repositoryService.activateProcessDefinitionById(definitionId, true, null);
      System.out.println("流程定义id:" + definitionId + "，已激活");
    } else {
      repositoryService.suspendProcessDefinitionById(definitionId, true, null);
      System.out.println("流程定义id:" + definitionId + "，已挂起");
    }
  }

  @Test
  public void suspendSingleProcessInstance() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RuntimeService runtimeService = processEngine.getRuntimeService();
    ProcessInstance instance = runtimeService.createProcessInstanceQuery().processInstanceId("15001").singleResult();
    boolean suspended = instance.isSuspended();
    String instanceId = instance.getId();
    if (suspended) {
      runtimeService.activateProcessInstanceById(instanceId);
      System.out.println("流程实例id:" + instanceId + "已经激活");
    } else {
      runtimeService.suspendProcessInstanceById(instanceId);
      System.out.println("流程实例id:" + instanceId + "已经暂停");
    }
  }

  @Test
  public void completTask() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    Task task = taskService.createTaskQuery().processInstanceId("15001").taskAssignee("zhangsan").singleResult();
    System.out.println("流程实例id==" + task.getProcessInstanceId());
    System.out.println("流程任务id==" + task.getId());
    System.out.println("负责人==" + task.getAssignee());
    System.out.println("任务名称==" + task.getName());
    taskService.complete(task.getId());
  }
}
12、使用uel表达式设置负责人
<process id="myEvection1" name="出差申请-uel" isExecutable="true">
  <startEvent id="sid-34c8a888-0fca-4ed3-a310-7c7e323e3f97"/>

                targetRef="sid-8991e623-e51a-4765-8dc4-043c9a2ea97b"/>
</process>

public class TestAssigneeUel {
  @Test
  public void testDeployment() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    Deployment deploy = repositoryService.createDeployment().name("出差申请流程-uel").addClasspathResource("bpmn/myEvection-uel.bpmn20.xml").deploy();
    System.out.println("流程部署id=" + deploy.getId());
    System.out.println("流程部署名字=" + deploy.getName());
  }

  @Test
  public void startAssigneeUel() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RuntimeService runtimeService = processEngine.getRuntimeService();
    Map<String, Object> assigneeMap = new HashMap<>();
    assigneeMap.put("assignee0", "张三");
    assigneeMap.put("assignee1", "李经理");
    assigneeMap.put("assignee2", "王总经理");
    assigneeMap.put("assignee3", "赵财务");
    runtimeService.startProcessInstanceByKey("myEvection1", assigneeMap);
  }
}
13、使用监听器设置负责人
<process id="testListener" name="测试监听器" isExecutable="true">
  <startEvent id="sid-9015503c-e6d8-4220-a895-7c4c3f7bb724"/>

      <activiti:taskListener event="all" class="com.itheima.demo.listener.MyTaskListener"/>
    </extensionElements>
  </userTask>
  <userTask id="sid-b5c63971-7df9-4928-b33b-36c83dda63bb" name="审核申请"/>
  <endEvent id="sid-e277723c-2c3b-4422-a942-bb81790fd077"/>
