SpringBoot 集成 activiti

基礎環境搭建

添加依賴

<dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-basic</artifactId> <version>6.0.0</version> </dependency>

添加配置文件

server: tomcat: uri-encoding: UTF-8 threads: # 最大工作線程數，默認200 max: 1000 # 最小工作空閑線程數，默認10。（適當增大一些，以便應對突然增長的訪問量） min-spare: 30 port: 8082spring: datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://127.0.0.1:3306/activiti6-demo?characterEncoding=utf8&useSSL=false username: root password: 123456 activiti: # 建表規則 # false 默認值。在啟動時會對比數據庫中保存的版本，如果沒有表或版本不匹配則拋出異常。生產環境常用 # true 對activiti所有表進行更新操作，不存在則自動創建。開發常用 # create_drop 在啟動時創建，在關閉時刪除（必須手動關閉引擎，才能刪除）。單元測試常用 # drop_create 在啟動時刪除原來的舊表，然后在創建新表（不需要手動關閉引擎） database-schema-update: true # 啟動的時候是否自動部署流程 check-process-definitions: false # 歷史數據 # none 不保存任何的歷史數據，因此，在流程執行過程中，這是最高效的 # activity 級別高于none，保存流程實例與流程行為，其他數據不保存 # audit 除activity級別會保存的數據外，還會保存全部的流程任務及其屬性。audit為history的默認值 # full 保存歷史數據的最高級別，除了會保存audit級別的數據外，還會保存其他全部流程相關的細節數據，包括一些流程參數等 history-level: audit # 不生成歷史表 activiti6默認啟用,activiti7默認關閉 db-history-used: true

在啟動類中排除安全配置就可以成功運行

@SpringBootApplication( exclude = SecurityAutoConfiguration.class)public class ActivityDemoApplication { public static void main(String[] args) { SpringApplication.run(ActivityDemoApplication.class, args); }}
