各個Service的做用：

RepositoryService	管理流程定義
RuntimeService	執行管理，包括啓動、推動、刪除流程實例等操做
TaskService	任務管理
HistoryService	歷史管理(執行完的數據的管理)
IdentityService	組織機構管理
FormService	一個可選服務，任務表單管理
ManagerService

 

1：RepositoryService

是Activiti的倉庫服務類。所謂的倉庫指流程定義文檔的兩個文件：bpmn文件和流程圖片。

1)     產生方式

 

2)     能夠產生DeploymentBuilder，用來定義流程部署的相關參數

 

3)     刪除流程定義

 

2：RuntimeService

是activiti的流程執行服務類。能夠從這個服務類中獲取不少關於流程執行相關的信息。

3：TaskService

是activiti的任務服務類。能夠從這個類中獲取任務的信息。

4：HistoryService

是activiti的查詢歷史信息的類。在一個流程執行完成後，這個對象爲咱們提供查詢歷史信息。
