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
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）
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
