Activiti集成SpringBoot实现流程部署的简单例子
发布时间：2023年12月17日
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
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
