老师，这个问题解决不了，修改了时区也没有用。

老师，我也出现了Xshell和物理机均ping不通虚拟机的问题，急需解决

只要链接就报错：

请输入：server，<port>或者：<ip>,<port>

今天重新启动了电脑之后在学这章内容登不上了

老师,代码19行中port后面的冒号是英文为什么还是不对.还有一个语法问题,请问老师这个是什么问题.

老师，生成booleanflag=list.add("bjsxt");这里的快捷键是什么呀

红框这里和老师的不一样，不清楚怎么添加vue工程。咋搞老师

；其实看看，想这种配置，就像是之前做项目的分层调用，控制层调用服务层，服务层调用持久层，持久层与数据库做交互。

其中，数据源是用于与数据库连接所需要的必要信息，jdbcTemplate是基于jdbc方式与数据库做交互，前提是需要数据库的连接信息，所以将数据源作为自己的属性；持久层是用于数据处理的，所以将jdbcTemplate作为其成员属性；服务层调用持久层，需要将持久层作为自己的属性。

老师，请问一下报这个错是不是密码错误的意思吗，应该在哪里输入密码呢，我一点击localhost，就报错，没有输入密码的步骤呢

老师，web项目不是直接就可以添加吗，为什么要自己新建文件夹呢

老师我这是爬取猫眼电影的你好李焕英，我的IP被禁止访问，我用了代理也不行，我试了多个免费高匿代理，还是不行，老师帮我看看，是我代码有问题吗？

老师您好，这个return是起到什么作用的呢？

为什么说找不到文件路径  可我是有这个文件的阿

老师，请教一下，我获取的 servletConfig对象是倒序的，帮忙看看哪里的问题？
