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: 8082
spring:
 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
