*  DiscussPostMapper
 *  DiscussPostService
 *  DiscussPostController
 *  index.html
    
     *  在帖子标题上增加访问详情页面的链接
 *  discuss-detail.html
    
     *  处理静态资源的访问路径
     *  复用index.html的header区域
     *  显示标题、作者、发布时间、帖子正文等内容

直接实现一下

先是数据层mapper

![在这里插入图片描述][dc336a26693941ab9b4abb647f9c3cbc.png_pic_center]

在映射文件中实现这个方法

<select id="selectDiscussPostById" resultType="DiscussPost">
            select
            <include refid="selectFields"></include>
            from discuss_post
            where id = #{id}
        </select>

![在这里插入图片描述][ae407e0088a149aabc2f129e52990dcc.png_pic_center]

下面是业务层

public DiscussPost findDiscussPostById(int id) {
        
            return discussPostMapper.selectDiscussPostById(id);
        }

![在这里插入图片描述][ce35b0dc226645f69fe1f9b036206f81.png_pic_center]

OK，最后是视图层

@RequestMapping(path = "/detail/{discussPostId}", method = RequestMethod.GET)
        public String getDiscussPost(@PathVariable("discussPostId") int discussPostId, Model model) {
        
            // 帖子
            DiscussPost post = discussPostService.findDiscussPostById(discussPostId);
            model.addAttribute("post", post);
            // 作者
            User user = userService.findUserById(post.getUserId());
            model.addAttribute("user", user);
    
            return "/site/discuss-detail";
        }

修改前端模板

先是修改首页，点击条目完成跳转

然后是帖子详情页的模板

同样是这些相对路径的本地资源

                    金三银四的金三已经到了，你还沉浸在过年的喜悦中吗？
                    如果是，那我要让你清醒一下了：目前大部分公司已经开启了内推，正式网申也将在3月份陆续开始，金三银四，春招的求职黄金时期已经来啦！！！
                    再不准备，作为19应届生的你可能就找不到工作了。。。作为20届实习生的你可能就找不到实习了。。。
                    现阶段时间紧，任务重，能做到短时间内快速提升的也就只有算法了，
                    那么算法要怎么复习？重点在哪里？常见笔试面试算法题型和解题思路以及最优代码是怎样的？
                    跟左程云老师学算法，不仅能解决以上所有问题，还能在短时间内得到最大程度的提升！！！
