0.springboot項目創建
通過https://start.spring.io/生成純凈的一個springboot工程
1.引入activiti相關依賴

<dependency> <groupid>org.activiti</groupid> <artifactid>activiti-spring-boot-starter</artifactid> <version>7.1.0.m6</version></dependency> |
2.啟動工程并創建activiti數據庫
##activiti7中使用spring security，因此啟動工程前，需要加入2個文件支持，2個文件的代碼如下：

##啟動springboot工程，讓系統啟動時幫我們建好25張表 2.安裝activiti插件（設計器） ##idea
file->settings->plugins，然后找actibpm進行安裝。
##流程圖中亂碼問題先提前設置防止：
修改idea64.exe.vmoptions文件，在文件中加上如下，然后重啟idea
-dfile.encoding=utf-8
##進行流程設計
file->new->bpmnfile
設計好后，修改process1.bpmn成process1.xml,然后右鍵export file導出成process1.jpg，再將process1.bpmn修改成process1.bpmn20.xml，最后將2個文件放在process文件夾
3.流程部署
使用activiti提供的api把流程定義內容存儲起來，activiti執行把流程定義內容存儲在數據庫中。

執行此操作后activiti會將上邊代碼中指定的bpmn20文件和圖片文件保存在activiti數據庫。
流程定義部署后操作activiti的3張表
4.流程實例啟動
啟動一個流程實例表示開始一次業務流程的運行

5.任務查詢
流程啟動后，任務的負責人就可以查詢自己當前需要處理的任務，查詢出來的任務都是該用戶的待辦任務。
