一、启动流程

多种方式启动

package com.wjy.pro;

import org.activiti.engine.ProcessEngine;

import org.activiti.engine.ProcessEngines;

import org.activiti.engine.RepositoryService;

import org.activiti.engine.RuntimeService;

import org.activiti.engine.TaskService;

import org.activiti.engine.repository.Deployment;

import org.activiti.engine.repository.ProcessDefinition;

import org.activiti.engine.runtime.ProcessInstance;

public class Start {

    public static void main(String[] args) {

        ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();

        // 存储服务

        RepositoryService rs = engine.getRepositoryService();

        // 运行时服务

        RuntimeService runService = engine.getRuntimeService();

        // 任务服务

        TaskService taskService = engine.getTaskService();

        // 部署

        Deployment dep = rs.createDeployment().addClasspathResource("start.bpmn").deploy();

        ProcessDefinition pd = rs.createProcessDefinitionQuery().deploymentId(dep.getId()).singleResult();

        // 启动流程

        ProcessInstance pi = runService.startProcessInstanceById(pd.getId(), "abc");

        //根据流程文件中定义process节点的id来启动

        //runService.startProcessInstanceByKey("");

        //根据消息名称启动流程  在流程定义的开始事件中加入消息定义 <messageEventDefinition/>

        //runService.startProcessInstanceByMessage("");

        System.out.println(pi.getId());

    }

}

二、流程操作与数据查询

1、流程触发-ReceiveTask

package com.wjy.handle;

import org.activiti.engine.ProcessEngine;

import org.activiti.engine.ProcessEngines;

import org.activiti.engine.RepositoryService;

import org.activiti.engine.RuntimeService;

import org.activiti.engine.TaskService;

import org.activiti.engine.repository.Deployment;

import org.activiti.engine.repository.ProcessDefinition;

import org.activiti.engine.runtime.Execution;

import org.activiti.engine.runtime.ProcessInstance;

public class ReceiveTaskTest {

    public static void main(String[] args) {

        ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();

        // 存储服务

        RepositoryService rs = engine.getRepositoryService();

        // 运行时服务

        RuntimeService runService = engine.getRuntimeService();

        // 任务服务

        TaskService taskService = engine.getTaskService();

        // 部署ReceiveTask类型任务

        Deployment dep = rs.createDeployment().addClasspathResource("receiveTask.bpmn").deploy();

        ProcessDefinition pd = rs.createProcessDefinitionQuery().deploymentId(dep.getId()).singleResult();

        // 启动流程

        ProcessInstance pi = runService.startProcessInstanceById(pd.getId());

        // 查当前的子执行流（只有一个）

        Execution exe = runService.createExecutionQuery()

                .processInstanceId(pi.getId())

                .onlyChildExecutions()

                .singleResult();

        System.out.println(pi.getId() + ", 当前节点：" + exe.getActivityId());//37505, 当前节点：receivetask1

        // 让它往前走  同complete

        runService.trigger(exe.getId());

        exe = runService.createExecutionQuery()

                .processInstanceId(pi.getId())

                .onlyChildExecutions()

                .singleResult();

        System.out.println(pi.getId() + ", 当前节点：" + exe.getActivityId());//37505, 当前节点：usertask1

    }

}

2、触发信号事件

public class MessageTest {

    public static void main(String[] args) {

        ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();

        // 存储服务

        RepositoryService rs = engine.getRepositoryService();

        // 运行时服务

        RuntimeService runService = engine.getRuntimeService();

        // 任务服务

        TaskService taskService = engine.getTaskService();

        // 部署

        Deployment dep = rs.createDeployment()

                .addClasspathResource("MessageEvent.bpmn").deploy();

        ProcessDefinition pd = rs.createProcessDefinitionQuery()

                .deploymentId(dep.getId())

                .singleResult();

        // 启动流程

        ProcessInstance pi = runService.startProcessInstanceById(pd.getId());

        // 查当前的子执行流（只有一个）

        Execution exe = runService.createExecutionQuery()

                .processInstanceId(pi.getId())

                .onlyChildExecutions()

                .singleResult();

        System.out.println(pi.getId() + ", 当前节点：" + exe.getActivityId());

        // 等待外面发送的消息才会让它往前走

//        <intermediateCatchEvent id="messageintermediatecatchevent1" name="MessageCatchEvent">

//            <messageEventDefinition messageRef="testMsg"></messageEventDefinition>

//        </intermediateCatchEvent>

        runService.messageEventReceived("testMsg", exe.getId());

        exe = runService.createExecutionQuery()

                .processInstanceId(pi.getId())

                .onlyChildExecutions()

                .singleResult();

        System.out.println(pi.getId() + ", 当前节点：" + exe.getActivityId());

    }

}

signal

package com.wjy.handle;

    public static void main(String[] args) {

        ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();

        // 存储服务

        RepositoryService rs = engine.getRepositoryService();

        // 运行时服务

        RuntimeService runService = engine.getRuntimeService();

        // 任务服务

        TaskService taskService = engine.getTaskService();

        // 部署

        Deployment dep = rs.createDeployment()

                .addClasspathResource("SingleEvent.bpmn").deploy();

        ProcessDefinition pd = rs.createProcessDefinitionQuery()

                .deploymentId(dep.getId()).singleResult();

        // 启动流程

        ProcessInstance pi = runService.startProcessInstanceById(pd.getId());

        // 查当前的子执行流（只有一个） createExecutionQuery

        Execution exe = runService.createExecutionQuery()

                .processInstanceId(pi.getId())

                .onlyChildExecutions()

                .singleResult();

        System.out.println(pi.getId() + ", 当前节点：" + exe.getActivityId());

        //等待外面传送定义的信号才会执行

//        <intermediateCatchEvent id="signalintermediatecatchevent1" name="SignalCatchEvent">

//            <signalEventDefinition signalRef="testSignal"></signalEventDefinition>

//        </intermediateCatchEvent>

        runService.signalEventReceived("testSignal");

        //流程查询createExecutionQuery

        exe = runService.createExecutionQuery()

                .processInstanceId(pi.getId())

                .onlyChildExecutions()

                .singleResult();

        System.out.println(pi.getId() + ", 当前节点：" + exe.getActivityId());

    }

}
