  • activiti-包含网关

    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.测试

      3.1 部署流程

    package com.wn.Inc;
    
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.ProcessEngines;
    import org.activiti.engine.RepositoryService;
    
    /*流程部署*/
    public class Deployment {
        public static void main(String[] args) {
            //获取ProcessEngine
            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
            org.activiti.engine.repository.Deployment deployment= repositoryService.createDeployment()
                    .addClasspathResource("bpmnfile/hoildayInc.bpmn")       //加载流程文件
                    .addClasspathResource("bpmnfile/hoildayInc.png")
                    .name("请假流程-包含网关")   //设置流程名称
                    .key("hoildayInc-Key")
                    .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());
        }
    }

        

      3.2 启动流程

        3.2.1 启动普通员工(1)的流程

    package com.wn.Inc;
    
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.ProcessEngines;
    import org.activiti.engine.RuntimeService;
    import org.activiti.engine.runtime.ProcessInstance;
    
    import java.util.HashMap;
    import java.util.Map;
    
    /*启动流程实例*/
    /*设置流程变量的值*/
    public class StartInstance {
        public static void main(String[] args) {
            //获取ProcessEngine
            ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
            //获取RuntimeService
            RuntimeService runtimeService = processEngine.getRuntimeService();
            //设置流程变量  启动流程时设置
            //定义一个map集合,存放assignee的值
            Map<String ,Object> assMap=new HashMap<>();
            assMap.put("userType",1);
            //启动一个流程实例
            ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("hoildayInc", assMap);
            System.out.println("流程实例ID:"+processInstance.getId());
        }
    }

          

        3.2.2 启动领导(2)的流程  

    package com.wn.Inc;
    
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.ProcessEngines;
    import org.activiti.engine.RuntimeService;
    import org.activiti.engine.runtime.ProcessInstance;
    
    import java.util.HashMap;
    import java.util.Map;
    
    /*启动流程实例*/
    /*设置流程变量的值*/
    public class StartInstance {
        public static void main(String[] args) {
            //获取ProcessEngine
            ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
            //获取RuntimeService
            RuntimeService runtimeService = processEngine.getRuntimeService();
            //设置流程变量  启动流程时设置
            //定义一个map集合,存放assignee的值
            Map<String ,Object> assMap=new HashMap<>();
            assMap.put("userType",2);
            //启动一个流程实例
            ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("hoildayInc", assMap);
            System.out.println("流程实例ID:"+processInstance.getId());
        }
    }

          

      3.3 提交流程

        3.3.1 提交流程(zhangsan)

    package com.wn.Inc;
    
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.ProcessEngines;
    import org.activiti.engine.TaskService;
    import org.activiti.engine.task.Task;
    
    /*提交任务*/
    public class CommitTask {
        public static void main(String[] args) {
            //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("hoildayInc").taskAssignee("zhangsan").singleResult();
            //任务处理
            taskService.complete(task.getId());
        }
    }

          当普通员工(1)执行的时候,会走常规体验项和抽血化验以及早餐,如果是高级领导(2)会走全部四项;

          

          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;

            //任务处理
            taskService.complete(task.getId());
        }
    }

            Task task = taskService.createTaskQuery().processDefinitionKey("hoildayInc").taskAssignee("wangwu").singleResult();
            //任务处理
            taskService.complete(task.getId());
        }
    }

            import org.activiti.engine.TaskService;
            import org.activiti.engine.task.Task;
    
    /*提交任务*/
    public class CommitTask {
        public static void main(String[] args) {
            //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("hoildayInc").taskAssignee("sunqi").singleResult();
            //任务处理
            taskService.complete(task.getId());
        }
    }

          当执行完成后,整个流程结束;
