上幾篇文章主要講了《實戰項目：設計實現一個流程編排框架(分析)》《實戰項目：設計實現一個流程編排框架(設計》《實戰項目：設計實現一個流程編排框架(實現)》,我們今天主要講一下基於分析、設計、實現的框架怎麼滿足一些基本場景。
方法節點
流程
流程執行三個方法節點，每個節點做+1操作，初始化count=0，最後輸出結果count=3；
文件定義
name: addCount
id: test1
desc: 方法節點執行
input: com.service.flow.sample.common.test1.Test1Input
output: com.service.flow.sample.common.test1.Test1Output
temp: com.service.flow.sample.common.test1.Test1Temp
startNode: node1
nodes:
- node:
id: node1
name: methodNode1
component: com.service.flow.sample.common.test1.Test1Component:count
desc: 數量+1
input: com.service.flow.sample.common.test1.Test1Input
type: method
next: node2

Bean節點
流程
流程執行三個bean節點，每個節點做+1操作，初始化count=0，最後輸出結果count=3；
文件定義

條件節點（循環節點）
流程
流程開始執行條件節點，初始化count=0；beanNode2每次做+1操作，當count>=5時，執行節點beanNode3，做+5操作，結果count=10；
文件定義
