步驟設置完畢以後，就要設置好流轉了，好比財務申請大於50000元（請假天數>5天）要總經理審批，不然財務審批以後就結束了。javascript

設置分支沒有任何關注點，咱們把關注點都放在了用戶的起草表單。因此本節如同設置字段，設置步驟同樣，只須要填充好Flow_StepRule表html

表結構：Flow_StepRule表主要是字段對比值，因此須要操做符，咱們約定操做符爲=、>、<、<=、>=、!=六種java

　　　　表Flow_StepRule的主表是Flow_Step，因此跟步驟同樣爲主從關係的設置json

我是這樣設計的，先獲取步驟列表，再按列表的步驟來設置分支，如圖ide
