SpringBoot集成activiti的示例代码

SpringBoot 集成 activiti 基础环境搭建添加依赖

org.activiti

activiti-spring-boot-starter-basic 6.0.0

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); }}
