## * Activiti 7 需要Spring Security, 所以需要加入Spring Security相关依赖包。原因: 流程一般是需要人签核的 * 绘制的流程图文件放在 resources/processes 文件夹中, 会自动部署流程到数据库 * 默认历史表不会自动生成,需要手动开启配置。 ``` db-history-used: true ``` https://github.com/LiXiongGithub/springboot_activiti/tree/master/src/main ``` @Configuration @EnableWebSecurity public class MySecurityConfig extends WebSecurityConfigurerAdapter { @Override @Autowired public void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(myUserDetailsService());
