3. 添加Activiti7配置
spring:
activiti:
database-schema-update: true # 对所有表更新操作，如不存在则创建 history-level: full # 保存历史数据的最⾼级别 db-history-used: true # 使⽤历史表
check-process-definitions: true # 校验流程⽂件:true-开启（默认）、false-关闭
4. 去掉SpringSecurity框架，修改启动类上的SpringBootApplication注解如下：
@SpringBootApplication(
exclude = {org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class,
org.springframework.boot.actuate.autoconfigure.security.servlet.ManagementWebSecurityAutoConfiguration.class, })
public class ActivitidemoApplication {
public static void main(String[] args) {
SpringApplication.run(ActivitidemoApplication.class, args);
}
}
5. 集成四个类分别如下
UserDetailsServiceImpl、UserGroupManagerImpl、Activiti7ApplicationConfiguration、SecurityUtil无尘黑板

//⽤户系统⽤的是三⽅免登，这⾥⽤userId作为唯⼀标识
LambdaQueryWrapper<UserRole> wrapper = new LambdaQueryWrapper<>();
wrapper.eq(UserRole::getUserId, userId);
List<UserRole> userRoles = userRoleService.list(wrapper);
List<SimpleGrantedAuthority> authorities = userRoles.stream().map(x -> new RoleId().toString())).Lis
//这⾥要填上⽤户的账号、密码(可以不填)和⾓⾊集合
return new User(userId, "", authorities);
}
}
