0.springboot項目創(chuàng)建
通過https://start.spring.io/生成純凈的一個springboot工程
1.引入activiti相關(guān)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(chuàng)建activiti數(shù)據(jù)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(tǒng)啟動時幫我們建好25張表 2.安裝activiti插件（設(shè)計器） ##idea
file->settings->plugins，然后找actibpm進(jìn)行安裝。
##流程圖中亂碼問題先提前設(shè)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(jìn)行流程設(shè)計
file->new->bpmnfile
設(shè)計好后，修改process1.bpmn成process1.xml,然后右鍵export file導(dǎo)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(nèi)容存儲起來，activiti執(zhí)行把流程定義內(nèi)容存儲在數(shù)據(jù)庫中。

執(zhí)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(shù)據(jù)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(yè)務(wù)流程的運行

5.任務(wù)查詢
流程啟動后，任務(wù)的負(fù)責(zé)人就可以查詢自己當(dāng)前需要處理的任務(wù)，查詢出來的任務(wù)都是該用戶的待辦任務(wù)。
