flowable测试demo

本文主要是介绍flowable测试demo，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

要构建的流程是一个非常简单的请假流程。Flowable引擎需要流程定义为BPMN 2.0格式，这是一个业界广泛接受的XML标准。

在Flowable术语中，我们将其称为一个流程定义(process definition)。一个流程定义可以启动多个流程实例(process instance)。流程定义可以看做是重复执行流程的蓝图。 在这个例子中，流程定义定义了请假的各个步骤，而一个流程实例对应某个雇员提出的一个请假申请。

BPMN 2.0存储为XML，并包含可视化的部分：使用标准方式定义了每个步骤类型（人工任务，自动服务调用，等等）如何呈现，以及如何互相连接。这样BPMN 2.0标准使技术人员与业务人员能用双方都能理解的方式交流业务流程。

我们要使用的流程定义为：

创建一个类，并运行一下：

package com.yuanbb.utils;

import org.flowable.engine.ProcessEngine;
import org.flowable.engine.ProcessEngineConfiguration;
import org.flowable.engine.impl.cfg.StandaloneProcessEngineConfiguration;

/**
 * @Author 三分恶
 * @Date 2020/5/2
 * @Description 创建表格
 */
public class HolidayRequest {
    public static void main(String[] args) {
        //1、创建ProcessEngineConfiguration实例,该实例可以配置与调整流程引擎的设置
        ProcessEngineConfiguration cfg = new StandaloneProcessEngineConfiguration()
                //2、通常采用xml配置文件创建ProcessEngineConfiguration，这里直接采用代码的方式
                //3、配置数据库相关参数
                .setJdbcUrl("jdbc:mysql://localhost:3306/flowable_demo?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2b8&nullCatalogMeansCurrent=true")
                .setJdbcUsername("root")
                .setJdbcPassword("root")
                .setJdbcDriver("com.mysql.jdbc.Driver")
                .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
        //4、初始化ProcessEngine流程引擎实例
        ProcessEngine processEngine = cfg.buildProcessEngine();
    }
}

未配置日志：
