本文详细介绍了工作流中流程变量的概念及其应用场景，包括如何设置和获取流程变量，并提供了具体的Java代码示例。

前面已经说明了工作流的工作流程，接下来看一下流程变量在整个工作流程中扮演着什么样的角色。

流程变量：流程变量在整个工作流中扮演很重要的作用。例如，请假流程中有请假天数、请假原因等一些参数都为流程变量的范围，流程变量的作用域范围是只对应一个流程实例，也就是说各个流程实例的流程变量是不互相影响的。流程实例结束完成以后流程变量还保存在数据库中。

流程变量的作用：
1、用来传递业务参数（如：请假天数）
1.1 设置流程变量
1.2 获取流程变量

2、指定连线完成任务（同意和拒绝）

3、动态指定任务的办理人

第一步，记得先布置流程引擎哦。
