flowable-流程中心設計之網關(八)

簡介

網關主要作用是根據條件控制,判斷流向,主要分為連線，排他網關，並行網關，兼容網關，事件網關。

 

 

連線

說明

連線就是可以設置多條線路，如果有多條連線符合條件，那就選擇第一條在流程文件中出現的連線，如果沒有符合條件的，就是用默認線路。

排他網關

說明

排他網關好像一個人在分岔路口，只會選擇一條線路前進，如果有多條連線符合條件，那就選擇第一條在流程文件中出現的連線，如果沒有符合條件的，就是用默認線路。

並行網關

說明

並行網關用於表述流程的並發，並行網關可以讓一個執行流變成多個同時進行的並發執行流，也可以讓多個執行流合並為一個執行流，因此並行網關會有兩種行為，分岔和合並。

設計

發起人填表后,3條線上傳附件，然后匯集一起提交

 

包含網關

說明

兼容網關就好像排他網關和並行網關的結合體，與排他網關不同的是，兼容網關可以創建多條執行流，

換言之，如果多個條件成立，那么此時可以將它看做並行網關，而排他網關，多個條件成立時，只會選擇第一個定義的順序流。

設計

 

事件網關

說明

網關的每個外出順序流都要連接到一個中間捕獲事件
