flowable流程中心设计之会签(二)

说明 

某些业务场景,审核需要多个人审核,然后根据审核结果判定是通过还是拒绝,可以理解为投票

会签内置参数 

作用

 

用于会签决策相关

 

参数名字	说明
nrOfInstances	一共多少实例
nrOfCompletedInstances	已经完成审批数量(包含审批结果为通过和拒绝的)
nrOfActiveInstances	还未完成审批数量
${taskName}_approved_count	完成审批 审核结果为通过的数量(注:自定义扩展)
${taskName}_rejected_count	完成审批 审核结果为拒绝的数量(注:自定义扩展)

 

nrOfInstances、nrOfCompletedInstances、nrOfActiveInstances 注:此3个变量只能用于会签节点 如果需要应用全局则需要扩展因为会签节点是一个单独的execution parent指向processInstance的execution children则是其他会签任务的execution

这3个变量保存在会签节点的execution 而不是processInstanc的execution

 

会签相关配置

 

类型(多实例) 

Parallel

　　并行,指的如果我们配置了3人会签，3人可以同时在待办看到此任务并处理

sequential

　　串行,指的是如果我们配置了3人会签，则会需要串行执行，前一个人办理了后一个人才能看到

 

集合(多实例)

 

参与会签的人员列表参数变量,发起流程传入 如以下格式

{
    "startUserId":"张立秋",
    "businessKey":9072,
    "title":"张立秋[2022-01-12]发起的商品编辑流程9",
    "definitionKey":"test_3",
    "variables":{
        "managerUserIds":["小明1","小明2","小明3"]
    }
}

 

元素变量

 

遍历集会签人员集合的接收变量

 

任务派遣

 

集合(多实例) 和元素变量 任务派遣搭配则可以动态指定参与会签的人

比如集合多实例配置:managerUserIds

元素变量 managerUserId

任务派遣配置 ${managerUserId}

 

 

完成条件

 

结合内置参数,可以设置会签结束条件,比如会签设置了1000人参与 有50%完成了审批则会签结束

如:${nrOfInstances/nrOfCompletedInstances>=0.5}

不填写则默认:100%完成审批

 

基数

 

限制任务的数量,比如我设置5 集合多实例配置了100 则只会发起5个流程

不填写默认:不限制

 

结合自定义扩展变量完成流程判定

 

1.如果会签结束,判定如果有70%的人同意则通过

${经理级会签_approved_count/(经理级会签_approved_count+经理级会签_rejected_count)>=0.7}

2.小于70%则拒绝

${经理级会签_approved_count/(经理级会签_approved_count+经理级会签_rejected_count)<0.7}

状态判断 为自动完成节点 结果为通过

注:因为连线是表达式 所以借助自动审批通过的任务来完成会签任务的判断,如果会签结束还有正常任务则不需要此节点

 

后期扩展

增加一票否决权,和一票通过权

思路:发起流程调用方指定一票否决权和一票通过权的用户id 

以上例子的xml配置
