工作流模拟程序员面试过程情景如下：
1.开发知识面试或者笔试
2.人事面试

流程图：

 * <receiveTask>的例子来进行.
 * 
 * 
 * 为了测试方便，将获取服务的实现抽象出来，同时使用Spring自带的与JUnit4集成的工具（

请问你将它切换到mysql或者别的数据库过了吗？

试过了Mysql，项目采用MSSQL。

您好，咨询个问题，真正项目中用的话，是用activiti-explorer的界面，在其中部署，还是重新做一个?

目前我们的项目中activiti-explorer和自己的项目时分开的通过http协议访问activiti的服务。起始activiti-explorer的界面只是在项目部署的时候使用可以采用编程方式自己实现，并不是必须的。
