Activiti集成SpringBoot实现流程部署的简单例子

2023-12-13 04:56:36

学习SpringBoot整合Activiti遇到的几个问题
1.连接controller时跳转登录页面，这是因为Activiti依赖中存在security包
可以选择在启动类上屏蔽security.class和org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class

但是因为我依赖中没加security的依赖决定在yml配置中添加账号密码
不添加这个的话，原始账号是user 密码是启动类运行下面提供的编码

配置中可以把自动部署关掉在这里插入图片描述

搞完这些就可以解决登录问题
在这里插入图片描述
找了很多文章，没有找到一个完美的集成，东拼西凑自己写了下。有的地方可能存在问题目前就是想实现在SpringBoot中成功部署流程。
首先application.yml配置

# 应用服务 WEB 访问端口
server.port: 8081
spring:

  # 数据源配置
 datasource:
  driver-class-name: com.mysql.cj.jdbc.Driver
  url: jdbc:mysql://localhost:3306/activiti7? nullCatalogMeansCurrent=true&serverTimezone=UTC&characterEncoding=UTF8&nullCatalogMeansCurrent=true
  username: "root"
  password: "123456"
  type: com.zaxxer.hikari.HikariDataSource
  hikari:
  # 等待连接池分配连接的最大时间（毫秒），超过这个时长还没有可用的连接，则会抛出SQLException
   connection-timeout: 30000
  # 最小连接数
   minimum-idle: 5
  # 最大连接数
   maximum-pool-size: 20
  # 自动提交
   auto-commit: true
  # 连接超时的最大时长（毫秒），超时则会被释放（retired）
   idle-timeout: 600000
  # 连接池的名字
   pool-name: DataSourceHikariCP
  # 连接池的最大生命时长（毫秒），超时则会被释放（retired）
   max-lifetime: 18000000
 security:
    user:
     name: root
     password: 123456
 # activiti7配置
 activiti:
  # 自动部署验证设置：true-开启（默认）、false-关闭
  check-process-definitions: false
  # 保存历史数据
  history-level: full
  # 检测历史表是否存在
  db-history-used: true
  # 关闭自动部署
  deployment-mode: never-fail
  # 对数据库中所有表进行更新操作，如果表不存在，则自动创建
  # create_drop：启动时创建表，在关闭时删除表（必须手动关闭引擎，才能删除表）
  # drop-create：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
  # 解决频繁查询SQL问题
  async-executor-activate: false

然后依赖
