一.前言
前面Activiti工作流的学习，说明了Activiti的基本应用，在我们开发中可以根据实际的业务参考Activiti的API去更好的理解以及巩固。我们实际的开发中我们基本上都使用spring框架进行开发，现在来说明一下Activiti工作流与spring集成，Activiti工作流与spring集成还算比较简单，可以参考Activiti的API来进行整合。

三.Activiti与spring整合xml配置文件
向spring配置文件中，添加一个spring-workflow2-activiti.xml配置文件，里面如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
