需要的jar包：

官网lib下的必要jar包，数据库驱动jar包以及mybatis-3.2.2.jar，其中部分jar需要在activiti-restWEB-INFlib下提取，如：activiti-process-validation-5.15.1.jar、joda-time-2.1.jar，数据库驱动需要与mybatis匹配：例如ojdbc6，myeclipse需要graphiti插件（myeclipse对graphiti的支持不如eclipse好）

activiti操作流程：

1.流程图操作：定义，部署，查看，删除

2.业务操作：启动业务（同时指定下一个任务办理人），流程关联业务（a.流程变量，b,表中的字段business_key），查询个人业务，动态指定下一个任务办理人（自关获取当前用户的上级），办理业务（将url写到图中，执行时动态获取formkey,通过配置action返回值$(#url)获取）,查询任务（任务ID----->taskId------>business_key------------>申请表单信息）

3.查询流程操作：查询全部流程，查询当前用户的流程（根据传递的四个坐标参数x、y、width、height，定义div进行迭代）

注解:activiti可以使用流程表中的字段查询业务，也可以根据业务ID查询流程ID
