【flowable】十、flowable网关

我是靠谱客的博主儒雅衬衫，最近开发中收集的这篇文章主要介绍【flowable】十、flowable网关，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

flowable网关

网关（gateway）用于控制执行的流向。

网关用其中带有图标的菱形表示。该图标显示了网关的类型。

bpmn.gateway

不用网关也可以实现分支，比如之前通过流程变量，在连线的条件上设置分支条件，但这样有个缺点：如果条件都不满足，流程就结束了（并且是异常结束）。

而从网关出去的条件都不满足是直接抛出异常。

排他网关

排他网关（exclusive gateway）。当执行到达这个网关时，会按照所有出口顺序流定义的顺序对它们进行计算。选择第一个条件计算为true的顺序流（当没有设置条件时，认为顺序流为true）继续流程。

请注意这里出口顺序流的含义与BPMN 2.0中的一般情况不一样。一般情况下，会选择所有条件计算为true的顺序流，并行执行。而使用排他网关时，只会选择一条顺序流。当多条顺序流的条件都计算为true时，会且仅会选择在XML中最先定义的顺序流继续流程。如果没有可选的顺序流，会抛出异常。

排他网关用内部带有’X’图标的标准网关（菱形）表示，'X’图标代表异或的含义。请注意内部没有图标的网关默认为排他网关。BPMN 2.0规范不允许在同一个流程中混合使用有及没有X的菱形标志。

案例:

为了简单，各个处理人流程变量写死了，使用了固定的。请假天数使用了流程变量，动态赋值。

部署流程和启动流程

 /**
     * 部署流程
     */
    @Test
    public void deployment() {
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

        RepositoryService repositoryService = processEngine.getRepositoryService();
        repositoryService.createDeployment().name("排他网关流程").addClasspathResource("排他网关.bpmn20.xml").deploy();
    }

    /**
     * 启动流程实例
     */
    @Test
    public void startProcess() {
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

        RuntimeService runtimeService = processEngine.getRuntimeService();
        runtimeService.startProcessInstanceById("排他网关:1:47504");
    }

流程启动后，第一个任务是由员工受理：

/**
     * 员工任务
     */
    @Test
    public void task1() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取TaskService完成流程任务
        TaskService taskService = processEngine.getTaskService();

        //员工发起请假申请，所以这里设置下排他网关里面的请假天数流程变量
        //这里num=2,按照排他网关的条件设计，员工完成任务后，该任务流转到经理
        Map<String, Object> variables = new HashMap<>();
        variables.put("num", 2);

        //查询员工的任务
        Task task = taskService.createTaskQuery().processInstanceId("50001").taskAssignee("员工").singleResult();
        if (task != null) {
            taskService.complete(task.getId(), variables);
        }
    }

员工完成后，任务流转到经理，排他网关生效

需要注意：如果从网关出去的线所有条件都不满足的情况下会抛出系统异常

并行网关

网关也可以建模流程中的并行执行。在流程模型中引入并行的最简单的网关，就是并行网关（parallel gateway）。它可以将执行*分支（fork）为多条路径，也可以合并（join）*多条入口路径的执行。

并行网关的功能取决于其入口与出口顺序流：

**分支：**所有的出口顺序流都并行执行，为每一条顺序流创建一个并行执行。
**合并：**所有到达并行网关的并行执行都会在网关处等待，直到每一条入口顺序流都到达了有个执行。然后流程经过该合并网关继续。

请注意，如果并行网关同时具有多条入口与出口顺序流，可以同时具有分支与合并的行为。在这种情况下，网关首先合并所有入口顺序流，然后分裂为多条并行执行路径。

与其他网关类型有一个重要区别：并行网关不计算条件。如果连接到并行网关的顺序流上定义了条件，也会直接忽略该条件。

请注意并行网关不需要“平衡”（也就是说，前后对应的两个并行网关，其入口/出口顺序流的数量不需要一致）。每个并行网关都会简单地等待所有入口顺序流，并为每一条出口顺序流创建并行执行，而不受流程模型中的其他结构影响。

并行网关，用内部带有’加号’图标的网关（菱形）表示，代表*与（AND）*的含义。

部署流程并启动流程

/**
     * 部署流程
     */
    @Test
    public void deployment() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取RepositoryService部署流程
        RepositoryService repositoryService = processEngine.getRepositoryService();

        repositoryService.createDeployment().name("并行网关流程").addClasspathResource("并行网关.bpmn20.xml").deploy();
    }

    /**
     * 启动流程
     */
    @Test
    public void startProcess() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取RuntimeService启动流程实例
        RuntimeService runtimeService = processEngine.getRuntimeService();

        //参数是act_re_procdef表的主键
        runtimeService.startProcessInstanceById("并行网关:1:55004");
    }

执行完成后，会有一条员工的任务：

在这里插入图片描述

员工完成任务

/**
     * 员工完成任务
     */
    @Test
    public void completeTask() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取TaskService完成任务
        TaskService taskService = processEngine.getTaskService();

        //直接查询 "员工"的任务
        Task task = taskService.createTaskQuery().processInstanceId("57501").taskAssignee("员工").singleResult();
        //在后面总经理审批前端排他网关有个 请假天数的流程变量，这里也同步设置下
      	//这里设置的num=2.也就是最后不需要总经理审批，流程就结束了。
        Map<String, Object> variables = new HashMap<>();
        variables.put("num", 2);
        if (task != null) {
            taskService.setVariables(task.getId(), variables);
            taskService.complete(task.getId());
        }
    }

查看act_ru_task表：

在这里插入图片描述

在员工完成任务后，任务表生成了两条记录，即并行网关有几个分支，就会生成几个任务记录。并且，必须要等多个分支任务都完成后汇聚到一起，再流转到下一节点任务

还有一点：即使我们并行网关设置了条件，且代码中设置的流程变量只满足了一个条件，但依旧产生了两条任务，也就是并行网关并不会去解析我们设置的条件的

现在完成项目经理和技术经理的

/**
     * 项目经理完成任务
     */
    @Test
    public void completeTask2() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取TaskService完成任务
        TaskService taskService = processEngine.getTaskService();

        //直接查询 "项目经理"的任务
        Task task = taskService.createTaskQuery().processInstanceId("57501").taskAssignee("项目经理").singleResult();
        if (task != null) {
            taskService.complete(task.getId());
        }
    }

项目经理任务完成后，表中还有一条技术经理的任务，所以还需要把技术经理的任务完成

在这里插入图片描述

/**
     * 技术经理完成任务
     */
    @Test
    public void completeTask3() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取TaskService完成任务
        TaskService taskService = processEngine.getTaskService();

        //直接查询 "技术经理"的任务
        Task task = taskService.createTaskQuery().processInstanceId("57501").taskAssignee("技术经理").singleResult();
        if (task != null) {
            taskService.complete(task.getId());
        }
    }

等技术经理完成任务后，流程就结束了，因为在员工任务的那一步，num设置为2，不需要由总经理审批。act_ru_task表汇总已经没有该流程记录了。

这里的项目经理和技术经理审批没有前后顺序，不管哪个先执行完，都要等对方执行完后，流程才会走到下一个节点。

包容网关

可以把**包容网关（inclusive gateway）**看做排他网关与并行网关的组合。与排他网关一样，可以在包容网关的出口顺序流上定义条件，包容网关会计算条件。然而主要的区别是，包容网关与并行网关一样，可以同时选择多于一条出口顺序流。

包容网关的功能取决于其入口与出口顺序流：

**分支：**流程会计算所有出口顺序流的条件。对于每一条计算为true的顺序流，流程都会创建一个并行执行。
**合并：**所有到达包容网关的并行执行，都会在网关处等待。直到每一条具有流程标志（process token）的入口顺序流，都有一个执行到达。这是与并行网关的重要区别。换句话说，包容网关只会等待可以被执行的入口顺序流。在合并后，流程穿过合并并行网关继续。

并行网关不计算连线条件，包容网关计算连线条件

案例：

为了简单，各个处理人流程变量写死了，使用了固定的。请假天数使用了流程变量，动态赋值。

部署流程并启动流程

/**

    @Test
    public void deployment() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取RepositoryService部署流程

启动完成后，第一个任务由员工完成

查看act_ru_task表：

员工完成任务

在员工完成任务通向的下一个任务节点是包容网关，有请假天数的流程变量，需要设置下

之后根据请假天数的流程变量，包容网关判断条件并走向下一个任务节点。

/**
     * 员工完成任务
     */
    @Test
    public void completeTask() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

        TaskService taskService = processEngine.getTaskService();

        Task task = taskService.createTaskQuery().processInstanceId("70001").taskAssignee("员工").singleResult();
        if (task != null) {
            //设置请假天数流程变量
            Map<String, Object> variables = new HashMap<>();
            variables.put("num", 2);

            /**
             * 这里员工完成任务后，请假天数是2，按照包容网关的流程设计，该流程后续需要由项目经理过和人事经理审批。
             * 项目经理：连线未设置条件，本身就要执行
             * 人事经理：请假天数小于等于3天，满足
             * 技术经理：请假天数大于3天，不满足
             */
            taskService.complete(task.getId(), variables);
        }
    }

刷新act_ru_task表：包容网关流程出现了两个待处理的流程任务，包容网关生效

在这里插入图片描述

项目经理和人事经理完成任务

/**
     * 项目经理和人事经理完成任务
     */
    @Test
    public void completeTask2() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

        TaskService taskService = processEngine.getTaskService();

        /**
         * 项目经理和人事经理任务完成后，流程要么由总经理审批要么就直接结束了。
         * 通过排他网关判断，流程变量num不更新了，还是用开始员工申请的。
         */
        Task task = taskService.createTaskQuery().processInstanceId("70001").taskAssignee("项目经理").singleResult();
        taskService.complete(task.getId());

        Task task2 = taskService.createTaskQuery().processInstanceId("70001").taskAssignee("人事经理").singleResult();
        taskService.complete(task2.getId());
    }

根据条件，项目经理和人事经理完成任务后，流程直接结束。

事件网关

基于事件的网关（event-based gateway）提供了根据事件做选择的方式。网关的每一条出口顺序流都需要连接至一个捕获中间事件。当流程执行到达基于事件的网关时，与等待状态类似，网关会暂停执行，并且为每一条出口顺序流创建一个事件订阅。

请注意：基于事件的网关的出口顺序流与一般的顺序流不同。这些顺序流从不实际执行。相反，它们用于告知流程引擎：当执行到达一个基于事件的网关时，需要订阅什么事件。有以下限制：

一个基于事件的网关，必须有两条或更多的出口顺序流。
基于事件的网关，只能连接至intermediateCatchEvent（捕获中间事件）类型的元素（Flowable不支持在基于事件的网关之后连接“接收任务 Receive Task”）。
连接至基于事件的网关的intermediateCatchEvent，必须只有一个入口顺序流。

事件网关的执行原理？

网关的每一条出口顺序流，都需要连接至一个捕获中间事件。当流程执行到达基于事件的网关时，网关类似等待状态地动作：执行被暂停。并且，为每一条出口顺序流，创建一个事件订阅。流程的走向完全是由于中间事件的选择。而由哪一个事件来决定流程的走向则是由最先触发的事件来决定的。

监听器

//信号监听器
public class SignalListener implements TaskListener, ExecutionListener {

    @Override
    public void notify(DelegateExecution execution) {
        System.out.println("信号事件:执行监听器执行了...");
    }

    @Override
    public void notify(DelegateTask delegateTask) {
        System.out.println("信号事件:任务监听器执行了...");
    }
}
//定时监听器
public class TimerListener implements TaskListener, ExecutionListener {

    @Override
    public void notify(DelegateExecution execution) {
        System.out.println("定时事件：执行监听器执行了...");
    }

    @Override
    public void notify(DelegateTask delegateTask) {
        System.out.println("定时事件：任务监听器执行了...");
    }
}

技术经理和项目经理的分配人就在流程固定设置为技术经理和项目经理

部署流程和启动流程

/**
     * 部署流程
     */
    @Test
    public void deployment() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取RepositoryService部署流程
        RepositoryService repositoryService = processEngine.getRepositoryService();

        repositoryService.createDeployment().name("事件网关").addClasspathResource("事件网关.bpmn20.xml").deploy();
    }

    /**
     * 启动流程定义
     */
    @Test
    public void startProcess() {
        //获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //获取RuntimeService启动流程
        RuntimeService runtimeService = processEngine.getRuntimeService();
        //参数是act_re_procdef表的主键
        runtimeService.startProcessInstanceById("事件网关:1:77504");
    }

流程启动后，act_ru_task中不会有任务生成，只有定时或者信号事件任意一个触发后才会生成任务。

通过代码主动触发信号任务：

/**
     * 触发信号
     */
    @Test
    public void createSign() {
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

        RuntimeService runtimeService = processEngine.getRuntimeService();

        List<Execution> executions = runtimeService.createExecutionQuery().signalEventSubscriptionName("signal").list();
        for (Execution execution : executions) {
            //发送信号
            runtimeService.signalEventReceived("signal", execution.getId());
        }
    }
