Flowable工作流快速入门

最近要处理一个oa工作流相关需求，这里记录一下，有完整的代码及相关资源。抛砖引玉，有不对的地方请指教。

本项目里面有两个工作流--报销的工作流和请假的工作流，这里我只演示一个请假的工作流

github资源包括idea插件资源 github.com/zhuliangnan…

项目目录,其中lib中为两个idea插件资源,因为我用的是最新版的idea插件库里面找不到这个插件所以一并提供。一个是actibpm.jar用于生成bpmn文件,注意: jBPM文件为上面那个jar的配套文件,直接引入idea插件不要只单独引入里面的jar，本地的idea插件目录如下参考。 ps：虽然idea提供了两个插件可以画图，但是着实不好用。好吧，非常不好用。。末尾我会提供本地部署flowable-model的方法画图和相关教程,还有百度云资源。

1. jar包引入

        <!--flowable工作流依赖-->
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter</artifactId>
            <version>6.3.0</version>
        </dependency>

        <!-- druid数据库连接池-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.10</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

2. yml文件,数据库请大家自行创建

server:
  port: 8082

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/flowable?serverTimezone=Asia/Shanghai&useSSL=false&useUnicode=true&characterEncoding=utf-8
    username: root
    password: 123456
    driverClassName: com.mysql.jdbc.Driver
  resources:
#    static-locations: classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,classpath:/static/flowable-modeler
flowable:
  #关闭定时任务JOB
  async-executor-activate: false

3. MoneyProcess.xml文件生成

上面已经提供了两个插件资源，请引入使用，这里直接给出已经生成好的一个xml ps: 如果不知道如何使用请至文章末尾，有保姆级别教程教你一步一步画出来。

        try {
            out = httpServletResponse.getOutputStream();
            while ((legth = in.read(buf)) != -1) {
                out.write(buf, 0, legth);
            }
        } finally {
            if (in != null) {
                in.close();
            }
            if (out != null) {
                out.close();
            }
        }
    }

}

5. 几个Service节点对应文件

CheckService.java

import org.flowable.engine.delegate.DelegateExecution;
import org.flowable.engine.delegate.JavaDelegate;

/**
 * @author zln
 * @date 2021/08/29
 */
public class CheckService implements JavaDelegate {
    @Override
    public void execute(DelegateExecution delegateExecution) {
        System.out.println("对于请求参数进行check: \n 申请人:"+delegateExecution.getVariable("userId")
                +"申请金额:"+delegateExecution.getVariable("money"));
    }
}

FailService.java

import org.flowable.engine.delegate.DelegateExecution;
import org.flowable.engine.delegate.JavaDelegate;
/**
 * @author zln
 * @date 2021/08/29
 */
public class FailService implements JavaDelegate {


    @Override
    public void execute(DelegateExecution delegateExecution) {
        System.out.println("请求被拒绝check: \n 申请人:"+delegateExecution.getVariable("username")
                +"申请金额:"+delegateExecution.getVariable("money"));
    }
}

SuccessService.java

import org.flowable.engine.delegate.DelegateExecution;
import org.flowable.engine.delegate.JavaDelegate;
/**
 * @author zln
 * @date 2021/08/29
 */
public class SuccessService implements JavaDelegate {
    @Override
    public void execute(DelegateExecution delegateExecution) {
        System.out.println("请求被通过check: \n 申请人:"+delegateExecution.getVariable("username")
                +"申请金额:"+delegateExecution.getVariable("money"));
    }
}

以上就是这个流程需要的所有文件，大家也可以通过git下载。

4. 启动项目

flowable会为我们自动创建34个表，用于数据，历史记录，流程定义，运行实例等等。 请注意如果启动失败，解决错误以后，每次都需要把表数据清空，或者删除在再重新启动。

5. 测试

step.1 访问 http://127.0.0.1:8082/flowable-money/add?userId=测试1&money=400

step.2 根据返回的processid查看流程 http://127.0.0.1:8082/flowable-money/processDiagram?processId=10009

这里我们看到现在Manager节点进行审核

step.3 这里我们给他通过审核 http://127.0.0.1:8082/flowable-money/apply?approved=1&taskId=10016

ps：taskid在act_ru_task表中这里面存储了，流程id和taskid的对应关系

审核通过流程结束。act_ru_task的那个流程记录被删除。

工作流相关API服务介绍

RepositoryService

流程建立相关。比如流程定义，流程的部署，流程文件的查询，验证BpmnModel等，流程转换成bpmnModel，BpmnModel转化成流程文件(.bpm)等。关键方法如下：

//伪代码。关键代码
// 验证bpmnModel
 List<ValidationError> validationErrors = repositoryService.validateProcess(bpmnModel);

//流程的查询
repositoryService.createProcessDefinitionQuery().processDefinitionName(route.getId().toString()).singleResult();

// 通过bpmnmodel定义流程并部署流程
Deployment deployment = repositoryService.createDeployment().addBpmnModel(bpmnModel.getProcesses().get(0).getName()+".bpmn", bpmnModel).deploy();

//将流程转成bpmnModel
repositoryService.getBpmnModel(processDefinition.getId());

//根据processDef上的deploymentId获取流程定义生成的bpmn文件或者其他资源文件。
InputStream inputStream = repositoryService.getResourceAsStream(deploymentId, resourceName);

// 删除流程定义
repositoryService.deleteDeployment(processDefinition.getDeploymentId(), cascade);

RumtimeService

流程实例管理。管理流程实例的启动，推进，删除，获取流程实例当前状态等

// 启动实例。businessId为业务号，一般唯一。比如lotId。商品编码。业务层方便查找
runtimeService.startProcessInstanceById(processDefinition.getId(), businessId);

// trigger形式的过站 只适用于ReceiveTask S1表示当前流程所在的taskId
ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceBusinessKey(businessId).singleResult();

Execution execution = runtimeService.createExecutionQuery().processInstanceId(processInstance.getId()).activityId("S1").singleResult();

runtimeService.trigger(execution.getId());

HistoryService

流程历史查询，所有有关历史的查询都从这个Service中来。

// 整个业务的持续时间
List<HistoricProcessInstance> list = historyService.createHistoricProcessInstanceQuery().processInstanceBusinessKey(lotId).list();
String instanceId = "";
for (HistoricProcessInstance hpi : list) {
    instanceId = hpi.getId();
    System.out.println("流程定义文件->" + hpi.getProcessDefinitionId());
    System.out.println("ProcessInstance->" + hpi.getId());
    System.out.println("StartActivityId->" + hpi.getStartActivityId());
    System.out.println("EndActivityId->" + hpi.getEndActivityId());
    System.out.println("startTime ->" + hpi.getStartTime() + "EndTime->" + hpi.getEndTime() + "duration" + hpi.getDurationInMillis());
}

//业务流转过程中每站的记录
List<HistoricActivityInstance> list1 = historyService.createHistoricActivityInstanceQuery().processInstanceId(instanceId).list().stream().sorted(Comparator.comparing(HistoricActivityInstance :: getStartTime)).collect(Collectors.toList());
for (HistoricActivityInstance historicActivityInstance : list1) {
    System.out.println("------");
    System.out.println(historicActivityInstance.getActivityId());
    System.out.println(historicActivityInstance.getActivityName());
    System.out.println(historicActivityInstance.getActivityType());
    System.out.println("startTime ->" +historicActivityInstance.getStartTime() + "EndTime->" + historicActivityInstance.getEndTime() + "duration" + historicActivityInstance.getDurationInMillis());
}

TaskService

用于指定节点任务的主要Service.比如ReceiveTask, UserTask, MailTask,HttpTask等等。不同的Task具备了不同的处理方式。

Execution execution = runtimeService.createExecutionQuery().processInstanceId(processInstance.getId()).activityId("S1").singleResult();
runtimeService.trigger(execution.getId());

execution = runtimeService.createExecutionQuery().processInstanceId(processInstance.getId()).activityId("S2").singleResult();
runtimeService.trigger(execution.getId());

execution = runtimeService.createExecutionQuery().processInstanceId(processInstance.getId()).activityId("S3").singleResult();
runtimeService.trigger(execution.getId());

PS. Flowable-Modle本地部署

名称：flowable-6.4.0.zip 链接：pan.baidu.com/s/1ctXANv-3… 提取码：7a5u

step1.解压并启动

把wars里面文件部署到tomcat的wepapp目录项目，启动startup.bat就好了，war包会自动解压如下图。如果没有自动解压，请检查是否放到了C盘导致没有权限，另外tomcat的log里面也会有日志。实在不行手动解压就好了。 启动过程比较慢，启动完访问 http://localhost:8080/flowable-modeler

step3.画流程

首先创建一个流程

流程的简单介绍

相关重要节点如何配置截图 一般只需要配置name和id，name用于显示在图上的名字，id用于唯一标识，id不去设置它自己生成

Task节点设置

排它节点设置 排它节点需要设置条件，由上一步传过来的参数决定走向，这里我们需要一个approved变量，这里我图方便所有人审批都是用的一个方法如下图，大家关注在task节点通过或者不通过审核的同时传入了哪些变量给下一个节点(排它节点)使用。

Service节点

ps：Service节点的创建由Task节点创建而来如下图

Service节点就是对应我们代码里面的处理类，Class里面配置处理类的位置就好了，到达Service节点的适合就会去执行。

ok，以上就是画流程图的简单操作和对应代码的相关东西。完成图如下
