SpringBoot 集成 activiti的示例代码

SpringBoot 集成 activiti

基础环境搭建

添加依赖

<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: # 最大工作线程数，默认200 max: 1000 # 最小工作空闲线程数，默认10。（适当增大一些，以便应对突然增长的访问量） 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: # 建表规则 # false 默认值。在启动时会对比数据库中保存的版本，如果没有表或版本不匹配则抛出异常。生产环境常用 # true 对activiti所有表进行更新操作，不存在则自动创建。开发常用 # create_drop 在启动时创建，在关闭时删除（必须手动关闭引擎，才能删除）。单元测试常用 # drop_create 在启动时删除原来的旧表，然后在创建新表（不需要手动关闭引擎） database-schema-update: true # 启动的时候是否自动部署流程 check-process-definitions: false # 历史数据 # none 不保存任何的历史数据，因此，在流程执行过程中，这是最高效的 # activity 级别高于none，保存流程实例与流程行为，其他数据不保存 # audit 除activity级别会保存的数据外，还会保存全部的流程任务及其属性。audit为history的默认值 # full 保存历史数据的最高级别，除了会保存audit级别的数据外，还会保存其他全部流程相关的细节数据，包括一些流程参数等 history-level: audit # 不生成历史表 activiti6默认启用,activiti7默认关闭 db-history-used: true

现在运行项目报错

在启动类中排除安全配置就可以成功运行

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