先给大家总的说一下这个项目里面用到了哪些功能吧!后面有代码的解析,整个项目的代码已经进行封装了。
首先要说的就是登陆和注册页面,其中用到了前面分享的跳转页面和验证码以及toUpperCase()转换。
以上这张图就是登陆后的主页面,这里面用到了网站中常用的分页查询、session对象(后续还会出一章session与cookie的区别)、绑定数据以及基本的增删改查。
上面这张图可以说是相当于一个增删改查的模板,其中用到了文件上传
这个页面是点击主页面中的新闻主题进来的,也就是说当你对某一条新闻感兴趣的时候,你想了解的更详细的,就可以点击进去,并且可以评论参与该新闻的讨论当中,其中用到了文本编辑器+绑定数据。
这个可以相当于一个游客界面,如果你没登录的话,你可以点击登录注册账号,其中也用到了分页和绑定数据。
以下就是每个页面所对应的代码。
首先我们有四个表,用户表、新闻表、评论表、主题表。每个表都有实体类和方法类(之前出过一章学生管理系统,里面有18个功能,不懂得可以去看看),当你需要用到某个方法的时候就可以直接调用。
