activiti自定义流程之整合（一）：整体环境配置

结合之前所说的自定义流程的思路，分别是后台、前台、整合，之前的内容也分别进行了相关的练习和尝试，现在就该到了最后的整合了，依旧是以实现功能为目的，细节暂且不去管他。

因为我们实际项目后端用的是spring、spring mvc、mysql、mybatis，前台用的angular js，因此在整合时我也自己搭建使用了这样的环境。

1、 所使用的环境基础：eclipse4.4、mysql5.6、angularjs1.4、tomcat7、jdk1.7、maven3.2、spring4.0.9、activiit5.16、activiti-modeler5.16

2、

后端maven导包pom.xml文件如下：

3、

web项目基础配置web.xml如下：

[html]
view plain
copy

lt;/web-app>

4、

其他依赖环境，如下图中红线框起来的部分：其中包括使用angularjs依赖的js，整合activiti-modeler依赖的文件和使用ueditor插件所需的文件。（具体的文件可参考之前的博客内容）



5、后台spring基础配置文件spring.xml如下：

lt;/beans>

5、 整个项目结构如图：
