【项目】仿牛客网社区开发
第3章 Spring Boot 实践 开发社区核心功能
3 帖子详情
- 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>
- 1
- 2
- 3
- 4
- 5
- 6
- 7
- 8
下面是业务层
public DiscussPost findDiscussPostById(int id) {
return discussPostMapper.selectDiscussPostById(id);
}
- 1
- 2
- 3
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";
}
- 1
- 2
- 3
- 4
- 5
- 6
- 7
- 8
- 9
- 10
- 11
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
<!doctype html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">

<meta charset="utf-8">

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！！！
