数据库设计

社区首页

  1. 帖子实体类、mapper

  2. 查询帖子方法,分页

  3. 查询帖子数量

  4. 帖子和用户查询方式

    1. sql关联查询
    2. 先查帖子,查出userId再查用户

    使用第2种,因为这样更直观,而且之后存redis更方便、性能更好

  5. 主页展示,将帖子和用户返回给前端,放在model中

    1. index.html引入th模板,相对路径
    2. 帖子循环
      1. 用户头像
      2. 帖子内容th:utext
      3. 判断帖子类型是置顶还是精华 th:if
      4. 用户名
      5. 时间格式化

首页,前10

分页

  1. 获取当前页行的偏移量
  2. 获得总页数
