1、什么是包含网关
包含网关可以看做是排他网关和并行网关的结合体;和排他网关一样,你可以在外出顺序流上定义条件,包含网关会解析它们;但是主要的区别是包含网关可以选择多于一条顺序流,这和并行网关一样,包含网关的功能是基于进入和外出顺序流的;
分支:所有外出顺序流的条件都会被解析,结果为true的顺序会以并行方式继续执行,会为每个顺序流创建一个分支;
汇聚:所有并行分支达到包含网关,会进入等待状态,知道每个包含流程token的进入顺序流的分支都到达;这是与并行网关的最大不同;换句话说,包含网关只会等待选中执行了的进入顺序流;在汇聚之后,流程会穿过包含网关继续执行;
2、流程定义
3、部署流程
package com.zn; import org.activiti.engine.ProcessEngine; import org.activiti.engine.ProcessEngines; import org.activiti.engine.RepositoryService; import org.activiti.engine.repository.Deployment; import org.junit.Test; public class ActivitiInclusiveGateway { /** * 流程部署 */ @Test public void deployment() { //获取ProcessEngine对象 默认配置文件名称:activiti.cfg.xml 并且configuration的Bean实例ID为processEngineConfiguration ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); //获取RepositoryService对象进行流程部署 RepositoryService repositoryService = processEngine.getRepositoryService(); //进行部署,将对应的流程定义文件生成到数据库当中,作为记录进行保存 Deployment deployment = repositoryService.createDeployment() .addClasspathResource("bmpnfiles/holidayInclusiveGateway.bpmn") //加载流程文件 .name("请假流程-包含网关") //设置流程名称 .key("holiday") .deploy(); //部署 //输出部署信息 System.out.println("流程名称:" + deployment.getName()); System.out.println("流程ID:" + deployment.getId()); System.out.println("流程Key:" + deployment.getKey()); } }

4、启动流程实例(userType=1)
当userType=1执行的时候,会走常规体验项和抽血化验以及早餐,如果是userType=1会走全部四项;
package com.zn; import org.activiti.engine.ProcessEngine; import org.activiti.engine.ProcessEngines; import org.activiti.engine.RepositoryService; import org.activiti.engine.RuntimeService; import org.activiti.engine.repository.Deployment; import org.activiti.engine.runtime.ProcessInstance; import org.junit.Test; import java.util.HashMap; import java.util.Map; public class ActivitiInclusiveGateway { /** * 启动流程实例 */ @Test public void startInstance() { //获取ProcessEngine对象 ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); //获取RuntimeService RuntimeService runtimeService = processEngine.getRuntimeService(); //设置流程变量 Map<String, Object> assMap = new HashMap<>(); assMap.put("userType", 1); //启动流程实例 ProcessInstance holidayGroup = runtimeService.startProcessInstanceByKey("holidayInc", assMap); System.out.println("流程实例:" + holidayGroup.getId()); } }

5、任务处理
package com.zn; import org.activiti.engine.*; import org.activiti.engine.repository.Deployment; import org.activiti.engine.runtime.ProcessInstance; import org.activiti.engine.task.Task; import org.junit.Test; import java.util.HashMap; import java.util.Map; public class ActivitiInclusiveGateway { /* *任务处理 */ @Test public void completeTask(){ //获取ProcessEngine ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); //获取TaskService对象 TaskService taskService = processEngine.getTaskService(); //查询到自己的任务,然后通过任务ID进行提交 Task task = taskService.createTaskQuery().processDefinitionKey("holidayInc").taskAssignee("zhangsan").singleResult(); //任务处理 taskService.complete(task.getId()); } }

在走到包含网关时,需要判断条件,符合条件的分支,将会执行,最终进行汇聚;
6、任务处理
package com.zn; import org.activiti.engine.*; import org.activiti.engine.repository.Deployment; import org.activiti.engine.runtime.ProcessInstance; import org.activiti.engine.task.Task; import org.junit.Test; import java.util.HashMap; import java.util.Map; public class ActivitiInclusiveGateway { /* *任务处理 */ @Test public void completeTask(){ //获取ProcessEngine ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); //获取TaskService对象 TaskService taskService = processEngine.getTaskService(); //查询到自己的任务,然后通过任务ID进行提交 Task task = taskService.createTaskQuery().processDefinitionKey("holidayInc").taskAssignee("lisi").singleResult(); //任务处理 taskService.complete(task.getId()); } }

7、任务处理
package com.zn; import org.activiti.engine.*; import org.activiti.engine.repository.Deployment; import org.activiti.engine.runtime.ProcessInstance; import org.activiti.engine.task.Task; import org.junit.Test; import java.util.HashMap; import java.util.Map; public class ActivitiInclusiveGateway { /* *任务处理 */ @Test public void completeTask(){ //获取ProcessEngine ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); //获取TaskService对象 TaskService taskService = processEngine.getTaskService(); //查询到自己的任务,然后通过任务ID进行提交 Task task = taskService.createTaskQuery().processDefinitionKey("holidayInc").taskAssignee("wangwu").singleResult(); //任务处理 taskService.complete(task.getId()); } }

8、任务处理
package com.zn; import org.activiti.engine.*; import org.activiti.engine.repository.Deployment; import org.activiti.engine.runtime.ProcessInstance; import org.activiti.engine.task.Task; import org.junit.Test; import java.util.HashMap; import java.util.Map; public class ActivitiInclusiveGateway { /* *任务处理 */ @Test public void completeTask(){ //获取ProcessEngine ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); //获取TaskService对象 TaskService taskService = processEngine.getTaskService(); //查询到自己的任务,然后通过任务ID进行提交 Task task = taskService.createTaskQuery().processDefinitionKey("holidayInc").taskAssignee("sunqi").singleResult(); //任务处理 taskService.complete(task.getId()); } }

执行完成后,整个流程就结束:
