7. 效果


????看出Activiti默认使用Spring的security，添加配置，关闭安全认证，如下：

SpringBoot系列——Activiti7工作流引擎(二)

# 关闭activiti登录验证
security:
  basic:
    enabled: false

????重启后继续访问，可正常进入首页（如还是无法进入首页，请添加@EnableAutoConfiguration(exclude = {org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class})，或者从pom.xml中移除Security包）：


????点击我要请假后，得到流程实例ID，再查看流程图，如下：

????附上首页/index.html代码，其它页面相比比较简单：




最主要的是给自己增加知识的储备，有备无患。最后给大家分享Spring系列的学习笔记和面试题，包含spring面试题、spring cloud面试题、spring boot面试题、spring教程笔记、spring boot教程笔记、最新阿里巴巴开发手册（63页PDF总结）、2022年Java面试手册。一共整理了1184页PDF文档。私信博主（666）领取，祝大家更上一层楼！！！
