Activiti集成SpringBoot实现流程部署的简单例子

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: 8081spring:# 数据源配置 datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/activiti7" />=true&serverTimezone=UTC&characterEncoding=UTF8&nullCatalogMeansCurrent=trueusername: "root"password: "123456"type: com.zaxxer.hikari.HikariDataSourcehikari:# 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

然后是BPM.xml看好它的路径

启动类
