</beans>

 

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
