activiti自定义流程节点

activiti

为满足用户自定义流程，这里采用排他网关将所有流程节点相连接并设置好连线参数，用户可以自行配置每一节点后下一步的参数，达到流程配置的目的

取人规则

每个节点配置对应的取人规则，需要在对应的节点上绑定Task监听器来获取人员

• id

• rule_cd

• remote_rule_cd

  • 远程规则cd

• rule_type

  • every_one
  • user_fix
  • user_apply
  • dept_duty
  • dept_apply
  • dept_fix
  • office_duty
  • office_apply
  • office_fix

• company_cd

• user_cd

• orgn_cd

人员

• 所有人

  • rule_type
    • every_one

• 固定人员

  • rule_type
    • user_fix
  • user_cd
    • xxx

• 提交人

  • rule_type
    • user_apply

• 责任部门

• 申报科室

  • rule_type
    • office_apply
  • level
    • 4

• 固定科室

  • rule_type
    • office_fix
  • level
    • 4
  • orgn_cd
    • xxx

流程选取

用户配置多个流程，可以通过juel以及优先级等方法来匹配需要的流程

• id
• company_cd
• process_cd
• is_default
  • 一个公司仅一个
• juel
  • 需要解析juel表达式

        System.out.println("++++++++++++++++++++++++++++++++++++++++++++++");
    }
