flowable-流程中心設計之會籤(一)

說明 

某些業務場景,審覈需要多個人審覈,然後根據審覈結果判定是通過還是拒絕,可以理解爲投票

會籤內置參數 

作用

 

用於會籤決策相關

 

參數名字	說明
nrOfInstances	一共多少實例
nrOfCompletedInstances	已經完成審批數量(包含審批結果爲通過和拒絕的)
nrOfActiveInstances	還未完成審批數量
${taskName}_approved_count	完成審批 審覈結果爲通過的數量(注:自定義擴展)
${taskName}_rejected_count	完成審批 審覈結果爲拒絕的數量(注:自定義擴展)

 

 

nrOfInstances、nrOfCompletedInstances、nrOfActiveInstances 注:此3個變量只能用於會籤節點 如果需要應用全局則需要擴展因爲會籤節點是一個單獨的execution parent指向processInstance的execution children則是其他會籤任務的execution

這3個變量保存在會籤節點的execution 而不是processInstanc的execution

 

會籤相關配置

 

類型(多實例) 

Parallel

　　並行,指的如果我們配置了3人會籤，3人可以同時在待辦看到此任務並處理

sequential

　　串行,指的是如果我們配置了3人會籤，則會需要串行執行，前一個人辦理了後一個人才能看到

 

集合(多實例)

 

參與會籤的人員列表參數變量,發起流程傳入 如以下格式

{
    "startUserId":"張立秋",
    "businessKey":9072,
    "title":"張立秋[2022-01-12]發起的商品編輯流程9",
    "definitionKey":"test_3",
    "variables":{
        "managerUserIds":["小明1","小明2","小明3"]
    }
}

 

元素變量

 

遍歷集會籤人員集合的接收變量

 

任務派遣

 

集合(多實例) 和元素變量 任務派遣搭配則可以動態指定參與會籤的人

比如集合多實例配置:managerUserIds

元素變量 managerUserId

任務派遣配置 ${managerUserId}

 

 

完成條件

 

結合內置參數,可以設置會簽結束條件,比如會籤設置了1000人蔘與 有50%完成了審批則會簽結束

如:${nrOfInstances/nrOfCompletedInstances>=0.5}

不填寫則默認:100%完成審批

 

基數

 

限制任務的數量,比如我設置5 集合多實例配置了100 則只會發起5個流程

不填寫默認:不限制

 

結合自定義擴展變量完成流程判定

 

 

1.如果會簽結束,判定如果有70%的人同意則通過

${經理級會籤_approved_count/(經理級會籤_approved_count+經理級會籤_rejected_count)>=0.7}

2.小於70%則拒絕

${經理級會籤_approved_count/(經理級會籤_approved_count+經理級會籤_rejected_count)<0.7}

狀態判斷 爲自動完成節點 結果爲通過

注:因爲連線是表達式 所以藉助自動審批通過的任務來完成會籤任務的判斷,如果會簽結束還有正常任務則不需要此節點

 

後期擴展

增加一票否決權,和一票通過權

思路:發起流程調用方指定一票否決權和一票通過權的用戶id 

以上例子的xml配置
