之前有需要使用到Flowable鉴于网上的资料不是很多也不是很全也是捣鼓了半天因此争取能在这里简单分享一下经验帮助有需要的朋友也非常欢迎大家指出不足的地方。
一、监听器
在Flowable中我们可以使用监听器来完成很多流程业务比如指定任务处理人、任务通知提醒等操作在这里我们来简单尝试一下监听器的使用我们在上篇文章中使用的请假流程中来创建监听器。 如上图所示
事件 create任务创建的时候触发。assignment在分配处理人的时候触发。complete处理完成之后触发。all所有的行为都会触发
我们创建一下监听器指定一下事件类型这里用create其中org.flowable.TestTaskListener为自定义的一个java类 这里也提供了更新之后的xml文件

二、创建监听类
package org.flowable;import org.flowable.engine.delegate.TaskListener;
import org.flowable.task.service.delegate.DelegateTask;/*** Authorhyy* Date:2023/9/15* Description:*/
public class TestTaskListener implements TaskListener {Overridepublic void notify(DelegateTask delegateTask) {System.err.println( 监听器执行 );if(create.equals(delegateTask.getEventName()) ){System.out.println(你的业务操作....);}}
}
创建TestTaskListener实现TaskListener我们发现这个方法的关键信息都是从DelegateTask中获取name我们来看一下这个类
public interface DelegateTask extends VariableScope {//任务IDString getId();//任务名称String getName();void setName(String name);//描述String getDescription();void setDescription(String description);//优先级int getPriority();void setPriority(int priority);//实例IDString getProcessInstanceId();//流程定义IDString getProcessDefinitionId();Date getCreateTime();//任务主键String getTaskDefinitionKey();//是否终断boolean isSuspended();//租户IDString getTenantId();//表单keyString getFormKey();void setFormKey(String formKey);//事件String getEventName();//.......
}三、重新部署流程
在上一篇文章示例中我们在重新部署一下这个流程 Testpublic void testDeploy() {//1.获取ProcessEngine 对象ProcessEngine processEngine ProcessEngines.getDefaultProcessEngine();//2.获取RepositoryServiceRepositoryService repositoryService processEngine.getRepositoryService();//3.完成流程部署操作Deployment deploy repositoryService.createDeployment().addClasspathResource(MyHoliday.bpmn20.xml) //关联要部署的流程名称.name(请假流程).deploy(); //部署流程System.out.println(id: deploy.getId()); System.out.println(name: deploy.getName());System.out.println(key: deploy.getKey());}这里去ACT_RE_PROCDEF中找到部署ID为代码打印的ID数据我这里是35001,拿到他的ID_字段MyHoliday:2:35004去启动流程
四、启动流程
Testpublic void startTest() {ProcessEngine defaultProcessEngine ProcessEngines.getDefaultProcessEngine();RuntimeService runtimeService defaultProcessEngine.getRuntimeService();MapString, Object variables new HashMap();variables.put(firstAssigne, 张三);variables.put(deptAssigne, 李四);ProcessInstance processInstance runtimeService.startProcessInstanceById(MyHoliday:2:35004, variables);System.out.println(processInstance.getProcessInstanceId() processInstance.getProcessInstanceId());}发现控制台打印如下日志表示监听器执行完成
