没人出现这个错误吗，试了一下还是没搞定。。。。。。

为什么底色会变成了黑色呢？默认是灰色的。。。。。

请问老师：我的窗口怎么是这样子，而且不是飞机在动，是图片在向右移动

苹果电脑怎么进行path设置啊。。。 有没有苹果电脑的相关视频啊。 这我根本看不懂。。

苹果电脑是不是自带java的jdk呀？因为我在我电脑的控制面板看到了一样的图标

oracle中创建表Name时不可定义表列名name,报错ORA-00904;

是因为name是关键字吗？那需要使用name需要加“”，可老师没加啊？

为什么  网页的表单提交方式method=get。  获取请求参数时 方式使用post方式也可以获取到请求参数呢？

老师，这两个标签是什么意思呢，有点忘记了

老师你好！章节6-Django项目阶段-博客项目 往下都没有课件资料耶！比如Html素材...这些，方便提供下吗？

老师，jsp-api.jar这个jar包的作用是什么？

老师，我想问下，这个solr是按照视频一步步部署的，可就是不成功，会有什么别的原因么？试了几次了
