会签#

流程图绘制

注意上面几个参数
- 多实例类型用来判断串行并行
- 基数（有几个用户处理）
- 元素变量
- 集合（集合变量）
- 完成条件–这里填的是 ${nrOfCompletedInstances > 1 }

在任务监听器

package org.flowable.listener;

import org.flowable.engine.ProcessEngine;
import org.flowable.engine.ProcessEngines;
import org.flowable.engine.TaskService;
import org.flowable.engine.delegate.TaskListener;
import org.flowable.task.api.Task;
import org.flowable.task.service.delegate.DelegateTask;

public class MultiInstanceTaskListener implements TaskListener {

 @Override
 public void notify(DelegateTask delegateTask) {
 System.out.println("处理aaaa");
 if(delegateTask.getEventName().equals("create")) {
 System.out.println("任务id" + delegateTask.getId());
 System.out.println("哪些人需要会签" + delegateTask.getVariable("persons"));
 System.out.println("任务处理人" + delegateTask.getVariable("person"));
 ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();
 TaskService taskService = engine.getTaskService();
 Task task = taskService.createTaskQuery().taskId(delegateTask.getId()).singleResult();
 task.setAssignee(delegateTask.getVariable("person").toString());
 taskService.saveTask(task);
 }
 }

- 具体

部署并启动流程


 @Test
 public void deploy(){
 ProcessEngine processEngine= ProcessEngines.getDefaultProcessEngine();
 RepositoryService repositoryService = processEngine.getRepositoryService();
 Deployment deploy = repositoryService.createDeployment().name("ly画的请假流程-候选人")
 .addClasspathResource("请假流程-候选人.bpmn20.xml")
 .deploy();

 }
 @Test
 public void runProcess(){
 //设置候选人
 Map<String,Object> variables=new HashMap<>();
 variables.put("candidate1","张三");
 variables.put("candidate2","李四");
 variables.put("candidate3","王五");
 ProcessEngine engine=ProcessEngines.getDefaultProcessEngine();
 //获取流程运行服务
 RuntimeService runtimeService = engine.getRuntimeService();
 //运行流程
 ProcessInstance processInstance = runtimeService.startProcessInstanceById(
 "holiday-candidate:1:4",variables);
 System.out.println("processInstance--"+processInstance);
 }

查看数据库表数据
- 处理人为空
- 变量
- 图解

实际，作为登录用户如果是张三/李四或者王五，那它可以查看它自己是候选人的任务


 /**
 * 查询候选任务
 */
 @Test
 public void queryCandidate(){
 ProcessEngine processEngine=ProcessEngines.getDefaultProcessEngine();
 TaskService taskService=processEngine.getTaskService();
 List<Task> tasks = taskService.createTaskQuery()
 .processInstanceId("5001")
 .taskCandidateUser("张三")
 .list();
 for(Task task:tasks){
 System.out.println("id--"+task.getId()+"--"+task.getName());
 }
 }

拾取任务

任务分配-uel表达式#

通过变量指定来进行分配

首先绘制流程图（定义）
- 变量处理

之后将xml文件导出

流程定义的部署

流程部署深入解析#

使用eclipse打包部署(没有eclipse环境，所以这里只有截图) 将两个流程，打包为bar文件，然后放到项目resources文件夹中
这里是为了测试一次部署多个流程（定义，图）代码如下
部署完成后查看表结构
- act_re_procdef
  
  部署id一样
- act_re_deployment
- 结论：部署和定义是1对多的关系
每次部署所涉及到的资源文件
涉及到的三张表
- act_ge_bytearray
- act_re_procdef category–>xml中的namespace name–>定义时起的名称 key_—>xml中定义的id resource_name—>xml文件名称 dgrm_resource_name–>生成图片名称 suspension_state –> 是否被挂起
  
  tenant_id – >谁部署的流程
- act_re_deployment name_部署名
代码
主要源码 DeployCmd.class
DeploymentEntityManagerImpl.java
insert()方法插入并执行资源点开里面的insert方法

表结构#

尽量通过API动数据
ACT_RE：repository，包含流程定义和流程静态资源
ACT_RU: runtime，包含流程实例、任务、变量等，流程结束会删除
ACT_HI: history，包含历史数据，比如历史流程实例、变量、任务等
ACT_GE: general，通用数据
ACT_ID: identity，组织机构。包含标识的信息，如用户、用户组等等
具体的
- 流程历史记录
- 流程定义表
- 运行实例表
- 用户用户组表
源码中的体现

默认的配置文件加载#

对于

ProcessEngine defaultProcessEngine = ProcessEngines.getDefaultProcessEngine();
//-->
public static ProcessEngine getDefaultProcessEngine() {
 return getProcessEngine(NAME_DEFAULT); //NAME_DEFAULT = "default"
 }
//-->
public static ProcessEngine getProcessEngine(String processEngineName) {
 if (!isInitialized()) {
 init();
 }
 return processEngines.get(processEngineName);
 }
//-->部分

 /**
 * Initializes all process engines that can be found on the classpath for resources <code>flowable.cfg.xml</code> (plain Flowable style configuration) and for resources
 * <code>flowable-context.xml</code> (Spring style configuration).
 */
 public static synchronized void init() {
 if (!isInitialized()) {
 if (processEngines == null) {
 // Create new map to store process-engines if current map is null
 processEngines = new HashMap<>();
 }
 ClassLoader classLoader = ReflectUtil.getClassLoader();
 Enumeration<URL> resources = null;
 try {
 resources = classLoader.getResources("flowable.cfg.xml");
 } catch (IOException e) {
 throw new FlowableIllegalArgumentException("problem retrieving flowable.cfg.xml resources on the classpath: " + System.getProperty("java.class.path"), e);
 }
 //后面还有，每帖出来
 }
 }

注意这行classLoader.getResources("flowable.cfg.xml"); 需要在resources根目录下放这么一个文件

Flowable介绍#

flowable的历史
flowable是BPNM的一个基于java的软件实现，不仅包括BPMN，还有DMN决策表和CMMNCase管理引擎，并且有自己的用户管理、微服务API等
