老师，报错说 Dubbo 远程调用服务时出现了超时异常，但是我修改了超时时间后还是不行

老师，我在配置类上从properties文件注入druid配置信息，控制台说无法set注入

所以二次开发以后，sentinel使用的就是本地的sentinel了，而不使用虚拟机里的sentinel 了是吧

现在注册中心不是用nacos比较多吗

前两天还能连上

今天突然连不上了

为什么第8行不是volant.而是Volant.

啊，有个疑问啊老师，咱properties文件里不是只给到数据库名，他咋知道操作哪个表

老师，启动之后搜索补齐关键字，发现底下没有关键词出来，然后看了一下日志发现报错信息是指定的字段（Field）"tags"不是一个完整的建议字段。 但我对比了下视频里的代码发现都是一样的，而且向ES同步商品数据是成功的，不知道怎么解决了

报错了应该是在StudentMapper.xml里面的错误
