activiti自定义流程之整合（一）：整体环境配置

时间：2024-04-19 16:06:02

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：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. lt;web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3. xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

  51. </welcome-file-list>
  52. 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：
